1 What's New in OPMN?

This chapter describes the new features of Oracle Process Manager and Notification Server (OPMN) available in Oracle Fusion Middleware Release 11g (11.1.1.1.3).

This chapter includes the following topics:

Integration with Oracle Instance

Support with Oracle WebLogic Server

1.1 Integration with Oracle Instance

Each ORACLE_HOME can support multiple instances, each with its own configuration and diagnostic directory tree (ORACLE_INSTANCE). OPMN now operates from within an ORACLE_INSTANCE.

There are two basic subdirectories within the ORACLE_INSTANCE base directory: ORACLE_INSTANCE/config and ORACLE_INSTANCE/diagnostics/logs. Within each of these two directories each component has a specific directory tree with the format: component type/component name where component type is either the OPMN type value configured for the ias-component or the process-type id for the component, and component name is the id value configured for the ias-component.

For example, the default Oracle HTTP Server (OHS) install log configuration directory would therefore be:

ORACLE_INSTANCE/config/OHS/ohs1 (UNIX)

ORACLE_INSTANCE\config\OHS\ohs1 (Microsoft Windows)

The OPMN component type is always OPMN and component name is always opmn.

1.2 Support with Oracle WebLogic Server

In most Oracle Fusion Middleware installations an Oracle instance is associated with an Oracle WebLogic Server domain for management of system components using the Oracle Enterprise Manager Fusion Middleware Control Console (Fusion Middleware Control Console). In these deployments, OPMN is integrated with the WebLogic domain to provide remote management of system components.

Unlike prior releases of Oracle Fusion Middleware, OPMN not only manages system components in the local Oracle instance but it is also integrated with the WebLogic domain to provide remote system component management using either the Fusion Middleware Control Console and or the WLST command line.

Note:

For more information about Oracle Fusion Middleware management concepts refer to the Oracle Fusion Middleware Administrator's Guide.

2 Oracle Process Manager and Notification Overview

This chapter provides an overview of Oracle's Process Manager and Notification (OPMN) server for Oracle Fusion Middleware. It includes the following topics:

What is OPMN?

How OPMN Works

What System Components Does OPMN Manage?

2.1 What is OPMN?

Oracle Process Manager and Notification (OPMN) is installed and configured with the following installation types:

Web Tier Installation: OPMN manages Oracle HTTP Server and Oracle Web Cache

Oracle Portal, Forms, Reports, and Discoverer Installation: OPMN manages Oracle Portal, Oracle Forms Services, Oracle Reports, Oracle Business Intelligence Discoverer, and Oracle EM Agent and Service Manager

Oracle Identity Management Installation: OPMN manages Oracle Internet Directory and Oracle Virtual Directory

OPMN features the following functionality:

Provides a command-line interface for process control and monitoring for single or multiple system components.

Provides an integrated way to manage system components.

Enables management of system subcomponents and sub-subcomponents.

Channels all events from different system component instances to all system components that can utilize them.

Solves interdependency issues between system components by enabling you to start and stop components in order.

Enables customizing of enterprise functionality by using event scripts.

Enables gathering of host and system process statistics and tasks.

Provides automatic restart of system processes when they become unresponsive, terminate unexpectedly, or become unreachable as determined by ping and notification operations.

Provides automatic death detection of system processes.

Enables you to control an Oracle instance through modifications to the opmn.xml file.

An Oracle instance is a directory that contains a set of system components managed by a common OPMN.

The OPMN server should be started as soon as possible after turning on the computer. OPMN must be running whenever system components are turned on or off.

On Microsoft Windows, OPMN is created as a service for each Oracle instance.

Oracle Fusion Middleware components that are managed by OPMN should never be started or stopped manually. Do not use command line scripts or utilities from previous versions of Oracle Fusion Middleware for starting and stopping system components. OPMN must be the last service turned off whenever you restart or turn off your computer.

Use the Fusion Middleware Control Console and the opmnctl command line utility to start or stop system components.

Note:

Refer to Chapter 4 for more information about the opmnctl command.

2.2 How OPMN Works

OPMN consists of a core grouping of three components that interpret and convey notification information sent between system processes within the same or different OPMN servers.

The core of OPMN consists of the following three components:

Oracle Notification Server

Oracle Process Manager

PM Modules

Figure 2-1 shows the architecture of the core of OPMN.

Figure 2-1 OPMN Architecture

2.2.1 Oracle Notification Server

Oracle Notification Server (ONS) is the transport mechanism for failure, recovery, startup, and other related notifications between components in Oracle Fusion Middleware. It operates according to a publish-subscribe model: a system component receives a notification of a certain type for each subscription to ONS. When such a notification is published, ONS sends it to the appropriate subscribers.

Unlike previous versions of Oracle Fusion Middleware, ONS is not configured to discover other OPMN servers. OPMN does not need to connect to other OPMNs for normal operation because all administration is centralized in the WebLogic domain. The WebLogic domain establishes remote client connections to each OPMN server as needed.

2.2.2 Oracle Process Manager

Oracle Process Manager (PM) is the centralized process management mechanism used to manage system processes. The PM is responsible for starting, restarting, stopping, and monitoring every process it manages. The PM handles all requests sent to OPMN associated with controlling a process or obtaining status about a process. The PM is also responsible for performing death-detection and automatic restart of the processes it manages. The system processes that PM is configured to manage are specified in the opmn.xml file.

The PM waits for a user command to start a specific, or all system processes. When a process is stopped, the PM receives a request as specified by the request parameters.

The OPMN server consists of 2 processes. The first OPMN server process has only one purpose: to start the second OPMN server process when necessary. The second OPMN server process handles all request traffic and does all the work. If the second OPMN server process goes down as part of an opmnctl reload command or an unexpected crash it is restarted by the first OPMN server process.

On Microsoft Windows, the second OPMN server process is not restarted if it is deliberately terminated. Instead, the first OPMN server process exits as well. Recovering from this situation is accomplished by restarting the OPMN server from the command line or service manager.

The Fusion Middleware Control Console also uses PM to manage processes.

The PM uses the Oracle Notification Server to:

detect that a process has completed initialization and is ready to receive requests

determine what ports are in use

obtain component specific runtime information

2.2.3 PM Modules

The Oracle Process Manager Modules (PM Modules) implement system component-specific process management functionality. The PM Modules pass notification information returned by other system component PM Modules within the same or different OPMN servers.

The PM Modules:

handle any communications originating from the running component.

construct system component specific control information (how to start, stop, restart the component).

test responsiveness in an system component specific manner to determine if a component is responding to requests.

See Also:

Chapter 6 for the common configuration of the opmn.xml file.

2.3 What System Components Does OPMN Manage?

OPMN manages all system components including the Oracle EM Agent and Service Manager.

You can also configure OPMN to manage other processes (including Oracle and other third-party products) using the Custom PM Module. See Appendix A for more information about configuring a custom process.

OPMN manages the following Oracle Fusion Middleware components:

OHS

Oracle Web Cache

Oracle Internet Directory

Oracle Virtual Directory

Oracle Forms

Oracle Reports

Oracle Business Intelligence Discoverer

2.3.1 Oracle Enterprise Manager Fusion Middleware Control Console

In addition to OPMN, you can also manage your enterprise using the Fusion Middleware Control Console. The Fusion Middleware Control Console leverages the functionality of OPMN to manage your Oracle Fusion Middleware enterprise. Using a Web browser, Fusion Middleware Control Console provides a graphical interface that enables management of all system components in your network and enterprise.

See Also:

Oracle Fusion Middleware Administrator's Guide for more information about Oracle Fusion Middleware management.

3 The opmn.xml File

This chapter provides an overview of the opmn.xml file for Oracle Fusion Middleware. It features the following topics:

opmn.xml

Automatic Restart

OPMN Log Files

Security

IPv6 Support

3.1 opmn.xml

The ORACLE_INSTANCE/config/OPMN/opmn/opmn.xml file is the main configuration file for OPMN. The opmn.xml file contains information for PM and system component specific configuration. The opmn.xml file shows you which system components OPMN is managing on your system.

The opmn.xml file is divided into three main sections: log files, notification-server, and process-manager.

log files: The log files configuration by default fully enables the standard log but disables the debug log

notification server: The notification-server configuration includes the OPMN listener ports as well as secure connection definition. Optional <topology> opmn.xml file element can be manually added for OPMN discovery.

process manager: The process-manager configuration includes all information required for each managed component.

The opmn.xml file does not contain component-specific element names. Component specific management code is located in the PM modules which are loaded by OPMN at startup according to what has been specified in the modules section of the opmn.xml file.

Each level has a specific set of configurations. In addition, there are several configuration elements that are accepted at more than one level to provide the flexibility of applying a configuration across an entire system component or just part of a component.

<ias-component>
   <process-type>
      <process-set>

<ias-component>: This entry represents the system component. It enables management of the component for processes such as starting and stopping.

<process-type>: This subcomponent of the <ias-component> entry declares the type of process to run by association with a specific PM module.

<process-set>: This sub-subcomponent of the <ias-component> entry enables you to declare different sets of optional runtime arguments and environments for the system component. <process-set> is an optional configuration element.

The opmn.xml file contains system component entries arranged in the hierarchical structure shown in the following Example 3-1.

Example 3-1 Element Entries in opmn.xml File

<ias-component id="ohs1">
   <process-type id="OHS">
      <process-set id="OHS">....

3.2 Automatic Restart

OPMN gives the user control over automatic death detection and restart of components; you can configure the parameters by which OPMN determines a process has died and disable automatic restart for individual components.

OPMN monitors the operation of its managed processes by the following methods:

Operating system level detection of system process death

Periodic ping requests to system processes

Periodic status notification from system processes (reverse-ping)

The ping and notification functionality is only used where appropriate according to the functionality of the system component.

OPMN automatically restarts system components that terminate unexpectedly. OPMN also restarts processes that are unresponsive according to the result of notification and ping operations.

See Also:

Chapter 6 for more information about the common configuration of the opmn.xml file.

3.3 OPMN Log Files

The log files generated by OPMN provide important information that can help you identify and diagnose performance and configuration issues. The Fusion Middleware Control Console makes reviewing these log files easier by helping you locate and view system component log files.

See Also:

Oracle Fusion Middleware Administrator's Guide for additional diagnostic utilities

Section B.2.1 for more information about OPMN log files

3.4 Security

The OPMN local listener port used by ONS clients and PM administrative processes do not use Secure Socket Layer (SSL) encryption for security, but rely on two other mechanisms to ensure authorized access to the OPMN server:

OPMN binds the local listener port to the local host. Users on the local system can connect to this port and issue OPMN process control requests. Information requests are allowed on the OPMN request port, which is bound to the system IP. The request port does not have SSL encryption.

When the OPMN server process first starts up and successfully binds to the local port, it creates a string of printable ASCII characters which it uses as a key for local connections. All connection attempts on the local port must include this key or the connection is closed by the OPMN server. The ASCII character string is written into the ORACLE_HOME/opmn/.formfactor file. Processes that cannot access the .formfactor file are not permitted to interact with the OPMN server.

For security reasons, the OPMN server logs any attempts to connect to its local port with an invalid form factor key (a key that does not match the value written by this OPMN process into the .formfactor file). You may encounter the following:

You attempt to run the OPMN client manually with the wrong user identification. Only the application server user can read the value from the .formfactor file, and so requests or processes run as the wrong user is not able to provide the correct key to the OPMN server.

You attempt to run an OPMN client from the wrong Oracle instance. (It is possible to have multiple Oracle instances set up on the same system.) If the other Oracle instances have OPMN configured to use the same local port then the system process request from the wrong Oracle instance reads the wrong .formfactor file.

You have manually changed the local port configuration in the opmn.xml file and started a new OPMN server without first stopping the previous OPMN server. The new OPMN server runs, binds to the new port, and overwrites the .formfactor file. The previous OPMN server is now unreachable through the local port, and can only be shutdown through remote OPMN requests (if SSL and authentication are configured) or by manually stopping the previous OPMN server.

Oracle Fusion Middleware and the Oracle Database both use ONS. When these two products are installed onto the same host, an ONS port conflict may arise if the port values configured for ONS are the same for both the Oracle Database and the Oracle Fusion Middleware component.

ONS with the Oracle Database is only used for special configurations and therefore is typically never started. However, the database listener attempts to connect to the Database ONS server but ends up connecting to the ONS server that was installed with Oracle Fusion Middleware. ONS (as part of OPMN) is always started whenever Oracle Fusion Middleware is started.

Because the Oracle Database is installed in a different location than that of Oracle Fusion Middleware, the Database ONS does not have access to the .formfactor file that was created when OPMN started up with the Oracle Fusion Middleware. As a result, the database listener attempts to connect to OPMN; the DB listener interprets it as a its standalone ONS) without a form factor string. OPMN logs an error similar to the following in the ons.log file:

04/11/15 18:43:32 [4] Local connection 0,127.0.0.1,6100 invalid form factor

This is expected OPMN behavior; preventing client access to the ONS server unless they possess the correct formfactor string.

To avoid having the Oracle Database listener contact the system OPMN server, change the default local and remote port values for the ONS server that was installed with the Oracle Database.

3.5 IPv6 Support

ONS is able to concurrently support the IPv4 and IPv6 network interfaces.

IPv4 is version 4 of the Internet Protocol (IP). It was the first version of the Internet Protocol to be widely deployed, and forms the basis for most of the current Internet (as of 2004).

IPv4 uses 32-bit addresses, limiting it to 4,294,967,296 unique addresses, many of which are reserved for special purposes such as local networks or multicast addresses, reducing the number of addresses that can be allocated as public Internet addresses.

IPv6 is intended to address the concern that there are too few IP addresses available for the future demand of device connectivity (especially cell phones and mobile devices). IPv6 supports 340 undecillion (3.4 × 1038) addresses.

As shown in Figure 3-1, for output, such as debug or log records, each IPv4 identifier is displayed as four, eight bit fields for the address (each a three digit decimal format) and a single 16 bit field for the port (a five digit decimal format).

Each IPv6 identifier is displayed as eight 16 bit fields for the address (each a four digit hexidecimal format) and a single 16 bit field for the port (the five digit decimal format).

Figure 3-1 IPv4 and IPv6 Host Identifier

4 opmnctl Commands

This chapter provides an overview of opmnctl commands for Oracle Fusion Middleware components managed by OPMN. It features the following topics:

opmnctl

opmnctl Command Quick Reference

opmnctl Detailed Command Description

4.1 opmnctl

opmnctl is the supported tool for starting and stopping all components in an Oracle instance, with the exception of the Fusion Middleware Control Console. opmnctl provides a centralized way to control and monitor system components from the command line.

If OPMN is configured to discover other Oracle instances, you can use opmnctl to execute control and monitoring commands across multiple Oracle instances simultaneously.

The location of the opmnctl script determines which opmnctl commands you can use.

The opmnctl command exists in two distinct directory location paths:

ORACLE_HOME/opmn/bin/opmnctl: The opmnctl command ORACLE_HOME/opmn/bin/opmnctl location can only be used to create an Oracle instance or a component for an Oracle instance on the local system. opmnctl commands generated from this location cannot be used to manage system processes

ORACLE_INSTANCE/bin/opmnctl: The other opmnctl command which is located in the ORACLE_INSTANCE/bin/ directory location provides a per Oracle instance instantiation of opmnctl. The opmnctl command in this location must be used for managing processes for this Oracle instance and can also be used for creating components for the Oracle instance.

Note:

Oracle Fusion Middleware components managed by OPMN should never be started or stopped manually. Do not use command line scripts or utilities from previous versions of Oracle Fusion Middleware for starting and stopping system components. Use the Fusion Middleware Control Console and the opmnctl command line utility to start or stop system components.

Note:

Oracle recommends starting OPMN as the user that has installed Oracle Fusion Middleware.

4.1.1 opmnctl Syntax

For example, the following command starts all system processes configured for Oracle Web Cache:

opmnctl startproc ias-component=webcache1

Refer to Chapter 5 for additional opmnctl command examples.

Table 4-2 lists the attribute names and values that can be used with the opmnctl command:

Table 4-2 opmnctl Attribute Names and Values

Attribute Name
Attribute Values

ias-instance

Value should be the same as the value for the id attribute for the <ias-instance> element in the opmn.xml file.

ias-component

Value should be the same as the value for the id attribute for the <ias-component> element in the opmn.xml file.

process-type

Value should be the same as the value for the id attribute for the <process-type> element in the opmn.xml file.

process-set

Value should be the same as the value for the id attribute for the <process-set> element in the opmn.xml file.

mode

Value can either be sync or async. The default value is "sync, meaning that this request operates synchronously, and waits for the operation to complete before returning. "async indicates that the request returns immediately, while OPMN continues to perform the request until the operation finishes.

timeout

This can only be specified in sync mode. The value is in seconds. After this timeout expires, OPMN does not continue to perform the request for startproc operations. The request does continue for restartproc and stopproc operations. The timeout attribute overrides the configured timeout value for the request to take for each ias-instance, ias-component, process-type, and process-set value.

uniqueid

This value is assigned by OPMN after starting up. You can use this value when you execute the opmnctl restartproc and opmnctl stopproc commands.

sequential

If the value of the sequential attribute is true, each process or application targeted by the request is acted upon sequentially (one at a time). The request order of affected managed-process dependencies is honored.

report

If the value of the report attribute is true, OPMN reports the results of each part of the request as it completes (as each process starts, for example). The default behavior is for OPMN to wait until the entire request has completed before sending all of the results at once.

The target attributes of ias-instance, ias-component, process-type, and process-set may be specified in a hierarchical manner, with an ias-instance, a single ias-component within that ias-instance, a single process-type within the ias-component, and a single process-set within the process-type. Any of these attributes may be omitted, and treated as a wildcard (process-set is omitted, for example, then all process-sets under the specified process-type matches the request).

The target attributes may also be specified in a list of a single hierarchical type (a list of ias-components, for example).

Note:

If Oracle Internet Directory is managed by OPMN and an Oracle Internet Directory dependency (not a managed-process dependency for Oracle Internet Directory) is encountered as part of the request, and the request is expected to start both Oracle Internet Directory processes (such as an opmnctl startall request), the Oracle Internet Directory process will not start unless it has been configured in the opmn.xml file previously. Otherwise, the request times out with an Oracle Internet Directory dependency failure.

4.3.1.3 Verbose

Syntax: opmnctl verbose command

The opmnctl verbose option enables you to obtain detailed information about the command you are executing.

For example, the following command outputs the information shown in Example 4-2:

prompt> opmnctl verbose startproc ias-component=ohs1

Example 4-2 opmnctl verbose output

4.3.2 Server Control Commands

The opmnctl start, startall, reload, stopall, and shutdown commands enable you to control the OPMN server.

Server Control Commands on Microsoft Windows

opmnctl start

opmnctl startall

opmnctl stopall

opmnctl shutdown

opmnctl reload

Output is not generated for the successful execution of an opmnctl server control command. Refer to Appendix B if you receive any error messages during opmnctl command execution.

4.3.2.1 Server Control Commands on Microsoft Windows

On the Microsoft Windows operating system, OPMN is installed as a Windows service (Oracle<OracleHomename>ProcessManager) and it starts up automatically when you restart your computer. When you start or stop OPMN using Microsoft Windows Services you start or stop all system components on the local Oracle instance.

Use the Fusion Middleware Control Console and the opmnctl command line utility to start or stop system components.

4.3.2.2 opmnctl start

Syntax: opmnctl start

Use this command to start the OPMN server for a local Oracle instance without starting system processes.

Note:

OPMN starts up automatically on Microsoft Windows when you start or restart your computer. All system component processes are also started.

See Also:

Chapter 5 for OPMN command-line examples

4.3.2.3 opmnctl startall

Syntax: opmnctl startall [timeout=<seconds>]

Use this command to start OPMN as well as the system processes for a local Oracle instance. The startall is equivalent to the start command and the startproc command without arguments. Oracle recommends using the start or startproc command.

This command operates synchronously and waits for the operation to complete before returning. To set a timeout for the request, specify the timeout value in seconds.

Components with id-matching="true" will not start.

Enter the following command for additional detailed information:

opmnctl usage startall

On Microsoft Windows, you can also perform an opmnctl startall by starting the Oracle<OracleHomename>ProcessManager service in the Windows services control panel. The Oracle<OracleHomename>ProcessManager starts automatically when you start or restart your computer.

4.3.2.4 opmnctl stopall

Syntax: opmnctl stopall

Use the opmnctl stopall command to shut down the OPMN server as well as the system processes for the local Oracle instance. This request operates synchronously; it waits for the operation to complete before returning.

Shutting down the OPMN server is not necessary during normal operation. Shutting down the OPMN server prevents remote commands to OPMN from executing on the Oracle instance until OPMN is restarted.

The opmnctl stopall command should only be executed prior to shutting down OPMN and your computer. This request first tries to stop all system components gracefully. Processes which will not stop gracefully is forcefully shutdown. After stopping all managed processes, the OPMN daemon shutdowns itself.

The opmnctl stopall command should only be used when it is necessary to stop the OPMN daemon quickly in case of an emergency. Once started, the OPMN daemon should remain up until it is necessary to restart the computer or some other unforeseen administrative event occurs.To stop all system components without stopping the OPMN daemon, consider using the opmnctl stopproc command without any arguments.To restart the OPMN daemon without restarting any system components, consider using the opmnctl reload command. The opmnctl reload command is the appropriate command to use when the only goal is to restart the opmn daemon with a new configuration.

Use the opmnctl stopproc command if you want to stop all system processes.

Use the opmnctl reload if you want OPMN to reread its configuration.

Enter one of the following commands to obtain additional information:

opmnctl usage stopall

or

opmnctl usage shutdown

4.3.2.5 opmnctl shutdown

Syntax: opmnctl shutdown

Use the opmnctl shutdown command to shut down the OPMN server as well as the system processes for the local Oracle instance.

The opmnctl shutdown command quickly shutdowns the OPMN daemon and system components for the local Oracle instance.The opmnctl shutdown command is similar to the opmnctl stopall command but waits less time before initiating a forceful termination of system components. After all of the system components are stopped, the OPMN daemon shutdowns itself.

The opmnctl shutdown command should only be performed when it is necessary to stop the OPMN daemon. Once started, the OPMN daemon should remain up until it is necessary to restart the computer or some other unforeseen administrative event occurs.To stop all system components without stopping the OPMN daemon, consider using the opmnctl stopproc command without any arguments.To restart the OPMN daemon without restarting any system components, consider using the opmnctl reload command. The opmnctl reload command is the appropriate command to use when the objective is to restart the OPMN daemon with a new configuration.

On Microsoft Windows, you can also perform an opmnctl shutdown by stopping the Oracle<OracleHomename>ProcessManager service in the Windows services control panel.

Use the opmnctl stopproc command if you want to stop all system component processes.

Use the opmnctl reload if you want OPMN to reread its configuration.

Enter one of the following commands to obtain additional information:

opmnctl usage stopall

or

opmnctl usage shutdown

4.3.2.6 opmnctl reload

Syntax: opmnctl reload

Use this command to trigger the OPMN to reread its configuration files. This command restarts the OPMN server without restarting any system processes managed by OPMN. The OPMN server for the Oracle instance must be up and running.

Note:

On Microsoft Windows, you can highlight the Oracle<OracleHomename>ProcessManager in the services control panel and select Restart. The restart of the service is not equivalent to an opmnctl reload, however. This action is equivalent to an opmnctl shutdown followed by an opmnctl startall. It is a much slower operation than opmnctl reload because it restarts OPMN and all the processes managed by OPMN.

Enter the following command for additional detailed information:

opmnctl usage reload

See Also:

Section 4.3.1 for OPMN command definitions

4.3.3 Process Control Commands

The opmnctl process control commands enable you to start, stop, or restart single or multiple system components. You can control a system component at the <ias-component>, <process-set>, or <process-type> level.

This section describes the process control commands available with opmnctl. It includes the following process control commands:

opmnctl startproc, opmnctl restartproc and opmnctl stopproc

Progressive Request Reports

Sequential Requests

Output is not generated for the successful execution of an opmnctl process control command. Refer to Appendix B if you receive any error messages during opmnctl command execution.

4.3.3.1 opmnctl startproc, opmnctl restartproc and opmnctl stopproc

Syntax: opmnctl startproc [<attr>=<value>...]

              opmnctl restartproc [<attr>=<value>...]

              opmnctl stopproc [<attr>=<value>...]

Use these commands to start, restart, or stop system processes. The OPMN server for the Oracle instance must be up and running.

You can use attributes for these commands. If no attribute is supplied when executing startproc, stopproc, and restartproc, all system processes except components with id-matching="true" in the opmn.xml file is started.

The following attributes and values can be used with the startproc, stopproc, and restartproc commands:

ias-component, process-type, and process-set: The values for these attributes should be the same as the id value specified in the opmn.xml file. If no attribute is supplied, the command is applied to all system component processes other than those that are configured in the opmn.xml file with id-matching="true". To execute commands on components configured with id-matching="true", it is necessary to specify the ias-component argument.

mode: The mode attribute value can be either sync or async; the default value is sync. The sync value for mode causes the opmnctl command to operate synchronously and wait for the command to be executed completely before a return prompt is displayed. The timeout element can only be specified when the value of mode is sync. The value is specified in number of seconds. After the specified timeout expires, the operation is aborted for startproc but not for restartproc or stopproc. The opmnctl command prompt returns, the OPMN server continues to perform the opmnctl restartproc or stopproc command request until the operation is finished.

The async value for mode causes the return prompt to be displayed immediately, while the OPMN server continues to perform the opmnctl command request until the operation is finished.

uniqueid: This value is assigned by OPMN after starting up. You can use this value when you execute the restartproc and stopproc commands. You can obtain this value by entering the following command and obtaining the unique number for the system component in the uid column of the generated output:

opmnctl status -l

Attribute names other than those listed may be specified for some types of system processes managed by OPMN. Unique attribute name should be specific to each type of system process.

Using the opmnctl startproc, restartproc, or stopproc commands and attributes enables control of specific processes in your Oracle instance. You can execute the opmnctl startproc, restartproc, or stopproc commands at the <ias-component>, <process-type> and the <process-set> level.

The following command restarts Oracle Web Cache at the <process-type> level:

opmnctl restartproc ias-component=webcache1 process-type=WebCache

The following command stops Oracle HTTP Server at the <ias-component> level:

opmnctl stopproc ias-component=ohs1

Enter one of the following commands to obtain additional information:

opmnctl usage startproc

or

opmnctl usage restartproc

or

opmnctl usage stopproc

See Also:

Section 4.3.1 for OPMN command definitions

Chapter 5 for OPMN command-line examples

4.3.3.2 Progressive Request Reports

The report=true attribute when used with startproc, restartproc, or stopproc enables OPMN to report back on each part of a request as it completes. For example, if an opmnctl startproc request attempts to start 4 processes, OPMN reports back to the user the result of each process start attempt as soon as it completes.

4.3.3.3 Sequential Requests

By default an OPMN request is run for all affected processes at the same time, unless a dependency dictates a specific ordering. If the attribute sequential=true is specified when used with the startproc, restartproc, or stopproc command, then OPMN runs the request on a single process at a time, waiting for the request to complete on the first before running the request on the second. When the request has finished on one process, it works on the next.

Note that dependencies are still honoured, and take part in the request sequentially as well.

As shown in Figure 4-1, by default OPMN issues jobs for all processes in parallel such that they run at the same time (except when honoring dependencies). For example, with the following command:

> opmnctl startproc

Figure 4-1 Processes in Parallel

If the sequential attribute is set to true, OPMN performs the request upon one process at a time (shown in Figure 4-2).

For example the following command:

% opmnctl startproc sequential=true

starts all of the managed system processes sequentially.

Figure 4-2 Managed Process Sequential Request #1

OPMN is processing one managed process, before moving on the next shown in Figure 4-3.

As shown in Figure 4-3, when the request completes for the first managed process, the request starts on the next managed process.

Figure 4-3 Managed Process Sequential Request #2

As shown in Figure 4-4, all affected managed processes have completed the request.

Figure 4-4 Managed Process Sequential Request #3

4.3.4 Provisioning Commands

The opmnctl provisioning commands are used for provisioning system components within an Oracle instance. Use these commands to:

Create and delete an Oracle instance or system component.

Register and unregister an Oracle instance with a WebLogic domain for management using the Fusion Middleware Control Console.

Update an Oracle instance or system component registration with the WebLogic domain.

Note:

The opmnctl provisioning commands must use the following naming conventions:

Name must begin with a letter and contain only alphanumerics, hyphen(-) and underscore(_) characters.

Name must be no more than 30 characters long.

Name must be at least 4 characters long.

This section includes the following topics:

General Syntax

Alternative Syntax for Provisioning Commands

Common Arguments

Commands

4.3.4.1 General Syntax

opmnctl provisioning commands are invoked using the following syntax:

opmnctl  command  [-argName1  value1]  [-argName2  value2]  ...

The following provisioning commands are supported:

createinstance

createcomponent

deleteinstance

deletecomponent

registerinstance

unregisterinstance

updateinstanceregistration

updatecomponentregistration

4.3.4.2 Alternative Syntax for Provisioning Commands

Provisioning commands can also be invoked with the syntax used by other opmnctl commands:

opmnctl command [argName1=value1] [argName2=value2] ...

This alternate syntax follows the Attributes style (refer to Section 4.3.1.2) and accepts argument names presented in lower case. The alternate syntax is provided to allow greater uniformity between opmnctl commands.

Any opmnctl provisioning commands can be entered using either syntax.

For example, the following commands are equivalent:

opmnctl createcomponent -componentType OHS -componentName ohs1
opmnctl createcomponent componenttype=OHS componentname=ohs1

Both syntax styles can be combined within the same command.

4.3.4.3 Common Arguments

The following arguments generally apply to all provisioning commands, with the exception with component specific arguments that apply only to component-related commands:

Adminserver Arguments

Logging Arguments

Oracle Instance Arguments

Component Specific Arguments

4.3.4.3.1 Adminserver Arguments

administrative server (Adminserver) arguments denote how opmnctl should contact the Adminserver of the Oracle WebLogic Server domain.

The Adminserver values are stored in the Oracle instance as defaults for subsequent commands. opmnctl does not use or require the Adminserver values for a non-registered Oracle instance. See Section 4.3.4.4.1 about the createinstance command for creating a non-registered instance.

The Adminserver arguments are:

-adminHost : the Weblogic Adminserver host. The default value is the last successful command for the Oracle instance or local host.

-adminPort: the Weblogic Adminserver port. The default value is the last successful command for the Oracle instance; or 7001.

-adminProtocol: Weblogic Adminserver protocol. The default value is the last successful command for the Oracle instance; or t3.

-adminUsername: the Weblogic Adminserver login user name. The default value is the last successful command for the Oracle instance; otherwise you are prompted to type in their login user name.

-adminPasswordFile: the location of the file containing the administrative user (admin user) password. The default value is the last successful command for the Oracle instance; otherwise you are prompted to type in your admin user password.

4.3.4.3.2 Logging Arguments

By default, opmnctl logs the detailed provisioning errors and exceptions in the ORACLE_INSTANCE/diagnostics/logs/OPMN/opmn/provision.log file. For certain errors during execution of the createinstance command, specifically when the provision.log file has not been created yet, the detailed exception is indicated on the console. Log file locations can be specified using the -logFile argument.

-logFile: the location of provisioning log file.

-logLevel: the logging level of provisioning log. For example, INFO or FINER.

4.3.4.3.3 Oracle Instance Arguments

The -oracleInstance and -instanceName arguments are used primarily for the createinstance command. After the Oracle instance is created, the ORACLE_INSTANCE/bin/opmnctl directory provides a default Oracle instance home. The Oracle instance name is determined automatically.

The Oracle instance arguments are:

-oracleInstance: the Oracle instance root directory. This directory is only required when the opmnctl command is not executed from the Oracle instance home.

-instanceName: this command option is used for assigning an Oracle instance name when the Oracle instance is created or to verify the Oracle instance name afterward.

For the createinstance command, if the instanceName is not provided directly, the last directory name of the -oracleInstance is used as the Oracle instance name.

4.3.4.3.4 Component Specific Arguments

Commands that target a single component can accept arguments specific to the component type. For example, the -wcAdminPasswordFile argument is accepted when creating an Oracle Web Cache component but not when creating an OHS component.

These arguments are syntactically optional but must be understood to ensure proper configuration.

For details covering these specific arguments and how they should be used, refer to the Oracle Fusion Middleware Administrator's Guide.

A list of the arguments applicable to a system component can be displayed by including the component type when executing the opmnctl usage command.

For example:

opmnctl usage createcomponent -componentType OHS

4.3.4.4 Commands

This section describes the create series of commands. It includes the following sections:

createinstance

createcomponent

deleteinstance

deletecomponent

registerinstance

unregisterinstance

updateinstanceregistration

updatecomponentregistration

4.3.4.4.1 createinstance

The createinstance command creates an Oracle instance and registers It uses the following arguments:

Adminserver

Logging

Oracle Instance

-adminRegistration: the registration status for the created Oracle instance. Supported values are ON (registered) and OFF (non-registered). The default value is ON.

-opmnRemoteHost: the OPMN remote host. The default value is the computer canonical host name.

-opmnLocalPort: the OPMN local port value. The default port value is 6700 if the port is available.

-opmnRemotePort: the OPMN remote port value. The default port value is 6701 if the port is available.

For example:

opmnctl createinstance -oracleInstance /foo/bar/inst1 -adminHost myadminserver -adminPort 7001

or

opmnctl createinstance -oracleInstance /foo/bar/inst1 -adminRegistration OFF

4.3.4.4.2 createcomponent

The createcomponent command creates a component within an Oracle instance. The created component is consistent with the Oracle instance in regard to its registration state.

The createcomponent command uses the following arguments:

Adminserver

Logging

Oracle Instance

Component Specific Arguments

-componentType : the system component type

-componentName : the system component name

For example:

opmnctl createcomponent -componentType OHS -componentName ohs1 -proxyPort 8888

It is important to note that different system components feature different sets of arguments that are available for configuration. In the above command example, the -proxyPort usage is specific to the OHS component. For more information about component specific arguments refer to Section 4.3.4.3.4.

4.3.4.4.3 deleteinstance

The deleteinstance command deletes an Oracle instance and unregisters the Oracle instance and associated system components. A successful Oracle instance deletion removes all files of the Oracle instance except for the default provision.log file.

For example:

opmnctl deleteinstance

The deleteinstance command uses the following arguments:

Adminserver

Logging

Oracle Instance

-force: The -force argument forces the opmnctl deleteinstance command to proceed regardless of discrepancies in the Oracle instance. The command is enabled only with a value of true. The default value is false.

Please note that the -force option circumvents most pre-validation checks. Therefore, Oracle recommends using the -force option with caution. An example is shown in section Force deleteinstance.

Force deleteinstance

The deleteinstance command operates in a forced mode if the option -force true is included in the command. When used, this option directs opmnctl to proceed with the operation regardless of warnings and errors detected for the Oracle instance. Because the Oracle instance may be in a bad or non-responsive state, Oracle recommends explicitly providing non-required values that are associated and appropriate for the Oracle instance (for example, -instanceName, -adminHost, -adminPort) to ensure that the proper values are used.

During the course of cleanup, the forced deleteinstance command displays warnings and exceptions consistent with the damaged state of the Oracle instance. These warnings and exceptions are provided as visual feedback for the inconsistencies encountered and do not necessarily indicate that further corrective action is needed.

For example:

opmnctl deleteinstance -force true -instanceName instance1 -adminHost myadminserver -adminPort 7001

or

opmnctl deleteinstance -force true -instanceName instance1

4.3.4.4.4 deletecomponent

The deletecomponent command deletes a system component.

The deletecomponent command uses the following arguments:

Adminserver

Logging

Oracle Instance

-componentName: The system component name.

For example:

opmnctl deletecomponent -componentName ohs1

4.3.4.4.5 registerinstance

The registerinstance command switches the Oracle instance to a registered state and updates the Adminserver value.

The registerinstance command uses the following arguments:

Adminserver

Logging

Oracle Instance

For example:

opmnctl registerinstance -adminHost myhostname -adminPort 8000

4.3.4.4.6 unregisterinstance

The unregisterinstance command switches the Oracle instance to a non-registered state and updates the Adminserver value.

For example:

opmnctl unregisterinstance

The unregisterinstance command uses the following arguments:

Adminserver

Logging

Oracle Instance

-force: directs the opmnctl unregisterinstance command to proceed regardless of discrepancies in the Oracle instance. This option is only enabled with a value of true. The default value is false.

Please note that the -force option circumvents most pre-validation checks. Therefore, Oracle recommends using the -force option with caution. An example is shown in section Forced unregisterinstance

Forced unregisterinstance

The unregisterinstance command can operate in a forced mode when the option -force true is included.

This option directs opmnctl unregisterinstance to unregister the Oracle instance but limits the scope of these changes exclusively to the Adminserver. In other words, it unregisters an Oracle instance name from the Adminserver without examining or interacting with an Oracle instance (except optionally for writing to the provision.log file).

This mode can readily break registration associations. For example, executing this command with the name of a operational registered Oracle instance would put Adminserver and the Oracle instance out of synchronization. Afterward, the Adminserver no longer lists the Oracle instance or associated system components; however, in this example, the Oracle instance would still be configured as registered and but would fail most provisioning commands. Therefore, Oracle recommends using the -force option with caution.

For example:

opmnctl unregisterinstance -force true -instanceName instance1 -adminHost myadminserver -adminPort 7001

4.3.4.4.7 updateinstanceregistration

The updateinstanceregistration command updates information registered on the Adminserver for the Oracle instance. Specifically, the updateinstanceregistration command updates the registered OPMN remote port, OPMN remote host and OPMN wallet from the current OPMN settings.

The updateinstanceregistration command uses the following arguments:

Adminserver

Logging

Oracle Instance

For example:

opmnctl updateinstanceregistration

4.3.4.4.8 updatecomponentregistration

The updatecomponentregistration command updates settings registered on the Adminserver for the subject system component. These settings include the component proxy port, component proxy wallet, component mbean properties and Fusion Middleware Control Console component properties, plus other values specific to the type of component.

The updatecomponentregistration command uses the following arguments:

Adminserver

Logging

Oracle Instance

Component Specific Arguments

-componentName: the system component name

For example:

opmnctl updatecomponentregistration -componentName ohs1 -proxyPort 8889 ....

4.3.5 Status Commands

The opmnctl status commands enable you to determine the status of system component processes.

This section describes the command options available with the opmnctl command. It includes the following sections:

opmnctl status

opmnctl metric

opmnctl dmsdump

opmnctl ping

opmnctl set

opmnctl query

See Also:

Section 4.3.1.2 for information about attributes

Section 4.3.5.1.1 for information about the options for the status command of opmnctl

Section 4.3.5.1.2 for information about the opmnctl status -port command

4.3.5.1 opmnctl status

Syntax: opmnctl status [<options>]

The status command enables you to obtain information on the system processes managed by OPMN.

The output is a text table. Each row in the table represents one system process.

You can customize the status command in the following ways:

Change the information displayed about each system process

Remove the table headers from the output

Change the field separator

Change the record separator

Change the width of individual columns

Change the justification of the data in an individual column

Enter the opmnctl usage status command to obtain full details on how to use the status command.

Example 4-3, "opmctl Status Output" shows the output after entering the opmnctl status command for the AppSrv1 Oracle instance on host comp1 for the domain yourcompany.com:

Example 4-3 opmctl Status Output

opmnctl status

The uid information enables you to stop or restart an individual Oracle Fusion Middleware process.

For example, the following command stops the OHS process-type:

opmnctl stopproc uniqueid=1792746301

-fsep <string>: Use this option to assign a field separator value for your opmnctl status output. The default value is |.

-rsep <string>: Use this option to assign a record separator value for your opmnctl status output. The default value is \n.

-noheaders: Use this option if you do not want a header displayed after you run the opmnctl status command.

-fmt <fmtlist>: This is a single string containing one or more statistic identifiers connected together where each identifier has the following format: <statname>[<width>{<justification>]. The default value is: %cmp18%prt18%pid5R%sta8.

Table 4-3 lists the format string syntax for the <fmtlist> option:

Table 4-3 Format String Syntax

Format String Syntax
Description

<statname>

This must be one of the following:

clu: system farm name

ins: Oracle instance name

cmp: system component ID

prt: process-type ID

prs: process-set ID

idx: index of process in process-set

pid: operating system process ID

uid: OPMN uniqueid

typ: name for this kind of process

sta: process status

stm: start time (ms)

utm: up time (ms)

cpu: cpu time (ms)

mem: memory used (in KB)

por: port list

fpr: full detail port list

<width>

Specifies the size for the field. Output shorter than this value receives padding according to the specified <justification>. Output longer than this value is truncated, and terminated with '~'.

Default: width of each datum.

<justification>

Specifies the justification for the field. This enables you to justify output when it is less than the width. It is L, R, or C (left, right, or center justification).

Default: L

For example, the following command displays the output shown in Example 4-5:

prompt> opmnctl status -noheaders -fsep @ -fmt %cmp%prt%pid%sta

Example 4-5 opmnctl status -noheaders output

webcache1@WebCache-admin@1544@Alive
webcache1@WebCache@1545@Alive
ohs1@OHS@1543@Alive

See Also:

Section 4.3.1 for command definitions

Enter the following command for additional detailed information:

opmnctl usage status

4.3.5.1.2 opmnctl status -port

The opmnctl status -port command enables you to display the request connect string used to connect to the OPMN daemon. For example, the command:

opmnctl status -port

displays:

123.your_company.com:6200

This opmnctl status -port command is a convenient shortcut that replaces the need to look inside of the opmn.xml file to determine the request access port.

4.3.5.2 opmnctl metric

The opmnctl metric command enables you to print the DMS statistics for a system component process. The opmnctl metric has the following command and argument structure:

opmnctl metric op=<op> [<identifier>=<value>] dmsarg=<dmsargs>]

The opmnctl metric command uses the following command arguments:

op=<op>: Specifies the operation, where <op> can be either list or query.

A list operation does not use additional arguments. The target OPMN returns a list of managed system processes for which DMS metrics are available through the metric request.

A query operation returns the metric tree for the managed process or processes qualified by the <identifier>=<value> arguments (all available processes are assumed if no identifier arguments are specified).

local=<bool>: When set to true, this option limits the command to operate within the local Oracle instance. This is useful when OPMN has been configured to discover other Oracle instances.

<identifer>=<value>: Specifies which managed process or processes to query for DMS metrics. Multiple identifiers can be specified, and each is used to match the managed process with address properties (the list is inclusive).

The four standard properties are:

PROCESS_UID=<uid>:Where <uid> is the unique id for the target process. This value is obtained by the metric list operation, the opmnctl status command, or any similar method that is used to display OPMN DMS metrics.

PROCESS_UID=0: This property always specifies OPMN itself.

INSTANCE_UID=<instance>@<uid>: Where <instance> is the Oracle instance name for the target Oracle instance and <uid> is the unique id for the target process on the Oracle instance. This identifier is only valid if <instance> is the local Oracle instance name, or all OPMN servers in the farm are configured to connect to one another.

COMPONENT_NAME=<component-name>: Where <component-name> is the id value for the <ias-component> in the opmn.xml file. COMPONENT_NAME=opmn always specifies OPMN itself.

COMPONENT_TYPE=<component-type>: Where <component-type> is the type value for the <ias-component> in the opmn.xml file, or if that is not defined, the id value for the <process-type> element. COMPONENT_TYPE=OPMN always specifies OPMN itself.

dmsarg=<dmsargs>: Specifies the DMS specific options for the metric query. <dmsargs> is a single argument that may include multiple options for the DMS layer, each following the <attr>=<value> format, and each option seperated by an &.

For example: format=raw, format=xml&name=/ProcessInfo

Refer to the Oracle Fusion Middleware Performance Guide for additional metric options.

4.3.5.3 opmnctl dmsdump

Syntax: opmnctl dmsdump [<attr>=<value>[&<attr>=<val>...]]

The opmnctl dmsdump command enables you to print the Oracle Dynamic Monitoring Service (DMS) statistics for OPMN. You can obtain a printout of process control operations for specific system components. If no attributes are specified, performance data for all system component processes for your system components are printed out.

DMS enables you to monitor a specific performance metric, a set of performance metrics, or all performance metrics. Options allow you to specify a reporting interval to report the requested metrics.

Multiple <attr>=<value> pairs must be separated by an &. For example, the following opmnctl command:

opmnctl dmsdump "table=opmn_ons&format=xml"

outputs the set of statistics that are gathered for ONS. The output includes the ports that ONS listens on and the number of notifications that ONS has processed. The output is in.xml format rather than text. If you want to review the output in text format do not include &format=xml on the command line.

For more information about DMS performance metric attributes and values refer to the Oracle Fusion Middleware Performance Guide.

4.3.5.4 opmnctl ping

Syntax: opmnctl ping [<max_retry>]

The opmnctl ping command enables you to contact the local OPMN server to verify operation. <max_retry> specifies the maximum number of retry times. If <max_retry> is specified, the local OPMN is pinged every one second, until the command execution succeeds or <max_retry> is reached.

For example, the following command,

opmnctl ping 10

designates pinging of OPMN 10 times until the ping command succeeds

4.3.5.5 opmnctl set

Syntax: opmnctl set [<attr>=<value> ...]

The opmnctl set command sets the logging configuration for OPMN.

An attribute name must be specified along with an attribute value. The following attribute names are required by OPMN for this command:

target: the value for target can be either log or debug, which refer to the standard.log or the debug.log. The standard log is configured to include all possible log messages by default and it is recommended that users not change its settings. Refer to Appendix B for more information about OPMN troubleshooting.

Note:

Enable usage of the debug.log file only after conferring with Oracle Support. The debug.log file is used by Oracle Support to debug and diagnose OPMN issues. Messages that are contained in the debug.log file are typically not readily comprehensible to the user.

comp: specifies the OPMN internal components and subcomponents

4.3.5.5.1 The comp Attribute

The value for the comp attribute can be either ons or pm. Additionally, the attribute value can be a specific set of sub-components for either the ons or pm attributes.

The following values for comp specify the OPMN internal components and subcomponents:

internal:specifies the common internal information for OPMN

ons:specifies the ONS component information for OPMN

pm: specifies the PM component information for OPMN

Both the ons and pm components consist of subcomponents which may be specified using the component[subcomponents] syntax where component can be either ons or pm. If both ons and pm are specified together they must be separated by a semicolon in the opmn.xml file. If subcomponents are listed, the listed items must be separated by a comma.

process module information. Only modules which call the modLog() (or modDebug for the debug log) function yields output. A specific module or list of modules may be specified with modules(module-ids). module-ids can be specified with a colon seperated list of module-ids to be displayed: modules (module1-id:module2-id). module-ids that do not match a configured and enabled module are not processed.

Each subcomponent for ons and pm may be prefaced with the negation character,!, which deselects the subcomponent. By using all with negated sub-components, specific subcomponents can be easily eliminated from the display.

Components and subcomponents are set or negated in the order in which they are encountered. Therefore:

ons[all,!topology]

yields all ons subcomponents excluding topology, while the following:

ons[!topology,all]

yields all ons subcomponents including topology.

4.3.5.6 opmnctl query

Syntax: opmnctl query [<attr>=<value> ...]

The opmnctl query command enables you to query the logging configuration for OPMN.

The attribute name of target must be specified along with an attribute value. The value for target can be either log or debug, which refer to the opmn.log file or the opmn.dbg file, respectively. Refer to Section B.2.1, "OPMN log Files" for more information.

4.3.6 Help Commands

The opmnctl help commands enable you to obtain additional information regarding OPMN.

This section describes the help command options available with the opmnctl command. It includes the following sections:

Section 4.3.6.1, "opmnctl help"

Section 4.3.6.2, "opmnctl usage"

Section 4.3.6.3, "opmnctl validate"

For example, enter the following command to receive the output shown in Example 4-7:

opmnctl usage stopall

Example 4-7 opmnctl usage stopall output

opmnctl stopall [sequential=true] [report=true]

Stop opmn daemon and managed processes for local Oracle instance.

This request first tries to stop all managed processes gracefully.
Processes which will not stop gracefully will be forcefully shutdown.  After
stopping all managed processes, the opmn daemon will shutdown itself.

This request should only be performed when it is necessary to stop the opmn
daemon.  Once started, the opmn daemon should remain up until it is necessary to
restart the computer or some other rare administrative event occurs.

To stop all managed processes without stopping the opmn daemon, consider
using the stopproc command without any target arguments.

If the value of the sequential attribute is "true", each process will be stopped
upon sequentially (one at a time).

If the value of the report attribute is "true", opmn will report the results of
the attempt to stop each processes as it completes.
The default behavior is for opmn to wait until the entire request has completed
before sending all of the results at once.

To restart the opmn daemon without restarting any managed processes, consider
using the reload command.  The reload command is the appropriate command to
use when the only goal is to restart the opmn daemon with a new configuration.

This request operates synchronously and will wait for the operation to complete
before returning.

4.3.6.3 opmnctl validate

Syntax: opmnctl validate [<filename>]

The opmnctl validate command validates the XML syntax of the opmn.xml file. The default ORACLE_INSTANCE/config/OPMN/opmn/opmn.xml is validated when ORACLE_INSTANCE/bin/opmnctl is used. The <filename> can be specified by either the relative or absolute path.

5 Using OPMN

This chapter provides command-line examples on how to use OPMN for Oracle Fusion Middleware. It features the following topics:

Starting OPMN

Starting and Stopping All System Components

Starting and Stopping a System Component

Starting and Stopping all System Components of the Same Type

5.1 Starting OPMN

OPMN does not depend on any other system component being up and running before it can be started and used. The OPMN server should be started as soon as possible after turning on the host.

Use the following command to start OPMN without starting other system components:

opmnctl start

5.2 Starting and Stopping All System Components

Use the following command to start all system components of an Oracle instance:

opmnctl startproc

Use the following command to stop all system components of an Oracle instance:

opmnctl stopproc

5.3 Starting and Stopping a System Component

Use the following command to start a system component named ohs1:

opmnctl startproc ias-component=ohs1

Use the following command to stop a system component named ohs1:

opmnctl stopproc ias-component=ohs1

5.4 Starting and Stopping all System Components of the Same Type

Use the following command to start all system components of the type OID in an Oracle instance:

opmnctl startproc process-type=OID

Use the following command to stop all system components of the type OID in an Oracle instance:

opmnctl stopproc process-type=OID

6 opmn.xml Common Configuration

This chapter provides common configuration examples, and descriptions of elements and attributes for the OPMN opmn.xml file.

It contains the following topics:

Example of opmn.xml Elements and Attributes

opmn.xml Element and Attribute Descriptions

6.1 Example of opmn.xml Elements and Attributes

Example 6-1 shows all possible elements and attributes that may appear in an opmn.xml file that are not specific to any system components.

6.1.1 Global Definitions and Syntax

All paths, module data values, and environment values may reference the following global variables, which is expanded to their platform specific values:

Table 6-1 Global Variables and Definitions

Global Variable
Definition

ORACLE_HOME

Full path to ORACLE_HOME

ORACLE_INSTANCE

Full path to ORACLE_INSTANCE

:

The library path (or class path) separator (":" on Linux or ";" on Microsoft Windows, for example).

EXE_EXT

The executable file extension ("" on Linux or ".exe" on Microsoft Windows, for example)

SO_EXT

The shared library extension (".so" on Linux or ".dll" on Microsoft Windows, for example)

SHELL_EXT

The shell file extension (".sh" on Linux or ".bat" on Microsoft Windows, for example)

Each of the variables defined above must be referenced using the same syntax as an environment variable in Linux or Windows. For example any of these references, ORACLE_HOME, {ORACLE_HOME}, or %ORACLE_HOME% yields the full path to ORACLE_HOME.

OPMN also automatically converts path separators in any path, module data value, or environment value based upon the platform on which OPMN is running. For example, /oracle/instances/ias1 would remain the same on Linux, but on Microsoft Windows OPMN would convert it to \oracle\instances\ias1.

OPMN uses the ^ character as an escape character to disable path separator conversion for the following character, and so "^/" always yields "/" in the parsed string. Two ^ characters yields a single ^.

6.2 opmn.xml Element and Attribute Descriptions

This section describes the elements and attributes in the opmn.xml file that are not specific to any system components. This section also provides attribute descriptions of the elements.

opmn

Required: true
Default: none
Parents: none
Attributes: none

<opmn> is the top-level element in the opmn.xml file.

log

Required: false
Default: see attributes
Parents: <opmn>
Attributes: path, comp, rotation-size, rotation-hour

The configuration definitions for the OPMN log mechanism.

path="path" 

Required: true
Default: ORACLE_INSTANCE/diagnostics/logs/OPMN/opmn/opmn.log
Valid Values: The path name for the OPMN log file.

comp="comp-codes"

Required: true
Default: internal, ons, pm
Valid Values: A list of comp-codes. A semi-colon must be used to separate the items on the comp-codes list.

The comp attribute specifies the component codes for logged events. These codes can be viewed and changed dynamically at OPMN run-time using the following commands:

> opmnctl query target=log
> opmnctl set target=log comp=<comp-codes>

The default comp-codes for log already include all possible log messages, and it is recommended that you do not change the value.

The following comp-codes are displayed in the log and debug elements of the opmn.xml file:

internal: a log for the common internal information for OPMN

ons: a log for the ONS component information for OPMN

pm: a log for the PM component information for OPMN

Both the ons and pm components consist of subcomponents which may be specified using the component[subcomponents] syntax. The component can be either ons or pm (separated by a semicolon if both are specified). The list of valid subcomponents for the given component are each separated by a comma. For example, comp="ons[local,listener];pm".

The following Table 6-2 lists the ONS component codes.

process module information. Only modules which call the modLog() (or modDebug for the debug log) function yields output. A specific module or list of modules may be specified with modules(module-ids). module-ids can be specified with a colon separated list of module-ids to be displayed: modules (module1-id:module2-id). module-ids that do not match a configured and enabled module are not processed.

Each subcomponent (for ons or pm) may be prefaced with the negation character ! which deselects the subcomponent. By using the term "all" with negated sub-components, specific subcomponents are eliminated from the display.

Components and subcomponents are set or negated in the order in which they are encountered. The ons[all,!topology] yields all ons subcomponents excluding topology, while ons[!topology,all] yields all ons subcomponents including topology.

rotation-size="kBytes"

Required: false
Default: none
Valid Values: An integer.

The rotation-size is the maximum size in kilobytes of the log file. When the log file reaches the configured size, the OPMN logging mechanism closes the log, rename it with a time stamp suffix, and then create a new log file. This attribute may be used with rotation-hour.

rotation-hour="HOD"

Required: false
Default: none
Valid Values: An integer value between 0 to 23.

At the given hour of the day, the OPMN logging mechanism closes the log, renames it with a time stamp suffix, and then creates a new log file. This attribute may be used with rotation-size.

debug

Required: false
Default: see attributes
Parents: <opmn>
Attributes: path, comp, rotation-size, rotation-hour

The debug element contains the configuration definitions for the OPMN debug log mechanism.

Note:

Enable usage of the opmn.debug file only after conferring with Oracle Support. The opmn.debug file is used by Oracle Support to debug and diagnose OPMN issues. Messages that are contained in the opmn.debug file are typically not readily comprehensible to the user.

path="path"

Required: true
Default: ORACLE_INSTANCE/diagnostics/logs/OPMN/opmn/opmn.log
Valid Values: The path name for the OPMN debug log file.

comp="comp-codes"

Required: true
Default: none
Valid Values: A list of comp-codes. A semi-colon must be used to separate the items on the comp-codes list.

The comp attribute specifies the component codes for logged events. These codes can be viewed and changed dynamically at OPMN run-time using the following commands:

> opmnctl query target=log
> opmnctl set target=log comp=<comp-codes>

The values revert back to the configured values in the opmn.xml file when OPMN is reloaded.

The following comp-codes are displayed in the log and debug elements of the opmn.xml file:

internal: a log for the common internal information for OPMN

ons: a log for the ONS component information for OPMN

pm: a log for the PM component information for OPMN

Both the ons and pm components consist of subcomponents which may be specified using the component[subcomponents] syntax. The component can be either ons or pm (separated by a semicolon if both are specified). The list of valid subcomponents for the given component are each separated by a comma. For example, comp="ons[local,listener];pm".

The following Table 6-4 lists the ONS component codes.

modules

process module information. Only modules which call the modLog() (or modDebug for the debug log) function yields output. A specific module or list of modules may be specified with modules(module-ids). module-ids can be specified with a colon separated list of module-ids to be displayed: modules (module1-id:module2-id). module-ids that do not match a configured and enabled module are not processed.

Each subcomponent (for ons or pm) may be prefaced with the negation character ! which deselects the subcomponent. By using the term "all" with negated sub-components, specific subcomponents are eliminated from the display.

Components and subcomponents are set or negated in the order in which they are encountered. The ons[all,!topology] yields all ons subcomponents excluding topology, while ons[!topology,all] yields all ons subcomponents including topology.

rotation-size="kBytes"

Required: false
Default: none
Valid Values: An integer.

The rotation-size is the maximum size in kilobytes of the log file. When the log file reaches the configured size, the OPMN logging mechanism closes the log, renames the log with a time stamp suffix, and then creates a new log file.

The rotation-size attribute may be used with the rotation-hour attribute.

rotation-hour="HOD"

Required: false
Default: none
Valid Values: An integer value between 0 to 23.

The rotation-hour attribute for use with the log file at the specified time of day, the OPMN logging mechanism closes the log file, renames it with a time stamp suffix, and then creates a new log file. This attribute may be used with the rotation-size attribute.

notification-server

Required: true
Default: none
Parents: <opmn>
Attributes: interface

The notification-server element configures or, contains the elements to configure the ONS portion of OPMN.

interface="type"

Required: false
Default: any
Valid Values: any, IPv6, or IPv4

By default, OPMN supports both the IPv6 and IPv4 network interfaces (see Section 3.5 for information about IPv6 support). OPMN binds to both interfaces for its listener ports and attempts connections using either interface. OPMN always attempts to use the IPv6 interface first, if such an address is available. This behavior is the same as the default behavior for the Sun Java Virtual Machine (JVM).

Both IPv4 and IPv6, require that you use the same network for connection to other OPMN servers. For example, IPv6 forces OPMN to only use the IPv6 network interface even if the IPv4 interface is available. This means that OPMN is only be able to connect to (and be connected from) other OPMN servers that can use the same network interface. If you configure IPv6 or IPv4 on a system that does not provide the same network interface support, OPMN will not start.

ipaddr

Required: true
Default: none
Parents: <notification-server>
Attributes: remote, request

The iapddr element specifies host information for ONS listener threads and host port bindings.

remote="ip; ip"

Required: false
Default: none
Valid Values: an IP address (in the IPv4 or IPv6 format) or host name to which ONS binds its remote port. A list of IP values may be configured to force ONS to bind to a specific set of IP addresses. Each IP value must be separated by a semi-colon on the list.

The remote attribute is the IP address or host name to which ONS binds its remote port. The remote port is used for ONS to ONS communication. Notifications pass from ONS to ONS through the remote port, and OPMN uses ONS to route remote requests to other OPMN servers through the remote port.

request="ip; ip"

Required: false
Default: IP address for default system host name
Valid Values: an IP address (in IPv4 or IPv6 format) or host name to which ONS binds its request port. A list of IP values may be configured to force ONS to bind to a set of specific IP addresses. The values on the list must be separated by a semi-colon.

The request attribute is for the IP address or host name to which ONS binds its remote port. This port can only be used for obtaining status information.

port

Required: true
Default: none
Parents: <notification-server>
Attributes: local, remote, request

The port element contains configuration information for ONS listener threads host and port bindings.

local="port"

Required: true
Default: none
Valid Values: A valid port number.

The local attribute is for the ONS local port value.

remote="port"

Required: false
Default: none
Valid Values: A port number.

The remote attribute is for the ONS remote port value.

request="port"

Required: false
Default: none
Valid Values: A port number.

The request attribute is for the ONS request port value.

ssl

Required: false
Default: none
Parents: <notification-server>
Attributes: enabled, wallet-file, wallet-password, openssl-certfile, openssl-keyfile, openssl-password, and openssl-lib

The ssl element is used for ONS to ONS security and authentication configuration. You may configure either the Oracle SSL layer (wallet-file and wallet-password) or the Open SSL layer (openssl-certfile, openssl-keyfile, openssl-password, and openssl-lib). You cannot use both. If you configure both Oracle and Open SSL layers within the same opmn.xml file, the server will not start.

The Oracle SSL layer uses the libraries shipped with either the Oracle Fusion Middleware or Oracle Database products. The Oracle SSL layer uses the standard Oracle wallet.The Open SSL layer provides better performance, documentation, and support for encryption hardware. It also has uses less hardware space within OPMN. Open SSL is an open source tool kit to develop security protocols. You can find more information at:

http://www.openssl.org

enabled="boolean"

Required: true
Default: none
Valid Values: true or false

If the enabled value is set to true, it enables SSL connections for ONS.

wallet-file="path"

Required: false (for Oracle SSL only)
Default: none
Valid Values: The path name to the Oracle wallet.

wallet-password="password"

Required: false (for Oracle SSL only)
Default: none
Valid Values: A string for the wallet password.

The wallet-password attribute is the password string for the specified Oracle wallet.

openssl-certfile="path"

Required: true (for Open SSL only)
Default: none
Valid Values: The path name to the Open SSL cert file.

openssl-keyfile="path"

Required: true (for Open SSL only)
Default: none
Valid Values: The path name to the Open SSL key file.

openssl-password="password"

Required: true (for Open SSL only)
Default: none
Valid Values: A string for the openssl-keyfile password.

The openssl-password attribute is the password string for the specified openssl-keyfile.

openssl-lib="path"

Required: false (for Open SSL only)
Default: none
Valid Values: The path name to the Open SSL library.

tune

Required: false
Default: See attributes
Parents: <notification-server>
Attributes: io-timeout, io-idle, timeout

The tune element contains the information for the Tuneable Notification Server ONS parameters.

io-timeout="timeout"

Required: false
Default: 30
Valid Values: 0 or an integer value >= 4 and <= 3600

The io-timeout is the socket read timeout value in seconds used by each remote OPMN (or ONS) server directly connected to the local server. If the remote server does not receive any data across the connection with the local server in the configured io-timeout period, the remote server times-out the connection and close the socket. The io-timeout value is the timeout period remote OPMN (or ONS) servers uses for the local server.

The io-timeout value is also used as a timeout for resource cleanup after an ONS connection has disconnected. If the connection is reestablished before the timeout period, the resources are transferred to the new connection. Otherwise the resources are released after the timeout period has expired.

The io-timeout parameter should be increased for servers running on very busy or overloaded systems.

A value of 0 disables io-timeout checking on remote servers for the local server. The io-timeout disables cleaning up of failover participant state, duplicate notification detection state, and notifications queued for the down connection. Notifications continues to be queued until the connection is reestablished, which can consume an ever expanding amount of memory on the remote OPMN or ONS servers if the timeout check is disabled and the connection never comes back. The io-timeout parameter should only be set to 0 for debug purposes.

A configured non- zero value that is less than the minimum value is set to the minimum, and a value greater than the maximum is set to the maximum.

io-idle="interval"

Required: false
Default: io-timeout - ( io-timeout / 3 )
Valid Values: an integer value >= 2 and <= ( io-timeout - 2 )

The interval in seconds between sending a message to each remote server to which the local server is directly connected. If no normal network traffic is sent from the local server to any remote server in the configured interval, a message is sent to the remote server.

The io-idle parameter ensures that an idle but responsive OPMN server does not have its connection timed out when with a remote server. On busy systems, this value should be far enough below the io-timeout value such that there is enough time for the local server to queue and send the idle message to the remote server before the remote server detects the timeout.

If the io-timeout is 0, the io-idle attribute is ignored. A configured value that is less than the minimum value is set to the minimum, and a value greater than the maximum is set to the maximum.

timeout="timeout"

Required: false
Default: 20
Valid Values: an integer value >= 1 and <= 3600

The timeout parameter is the socket timeout value in seconds used for the local OPMN server for connection attempts and client connection writes. If the connection handshake to the local OPMN server takes longer than the configured timeout value, then the socket is closed and the connection resources are available. If a write on a client connection socket takes longer than the configured timeout value, then the socket is closed and the connection resources are available.

process-manager

Required: true
Default: none
Parents: <opmn>
Attributes: insecure-remote-requests

The process-manager contains the configuration definitions for the PM portion of OPMN.

insecure-remote-requests="boolean"

Required: false
Default: false
Valid Values: true or false

The insecure-remote-request attribute is a security check which disables requests until security features are configured. By default OPMN only allows start, stop, restart, shutdown and reload requests rerouted from remote OPMN servers if ONS SSL is enabled and a wallet file is configured for authentication.

Note:

Setting the insecure-remote-request attribute to true overrides that security check and enables these requests to be issued remotely with no security features configured.

Setting the insecure-remote-request attribute to true is a major security risk and should only be done for testing purposes with all connected OPMN servers behind a well secured fire wall or completely disconnected from any external network.

process-modules

Required: true
Default: none
Parents: <process-manager>
Attributes: none

Each process module is designed to support a specific set of process-type elements; it is only required if the process-type elements are configured. The PM dynamically loads in a library for each specified process module.

module

Required: true
Default: none
Parents: <process-modules>
Attributes: path, tag, status, cron

The module element is used to provide process-type specific support for the PM. Each module is implemented as a shared library. The module exports a set of standard functions and uses the PM process module API. A module must provide a list of the process-types it supports. Only one configured process module may list a specific process-type. No two modules can list the same process-type.

path="path"

Required: true
Default: none
Valid Values: The path name for the module shared library.

The path attribute must specify the path name of the shared library file. The library file has the system suffix of.so for Linux and .dll for Microsoft Windows. The suffix may be omitted and OPMN automatically appends it. ORACLE_HOME may be used when specifying the path name.

tag="tag-id"

Required: false
Default: The value specified by the path element.
Valid Values: A string uniquely identifying the module.

The tag attribute identifies the module. A module may report its tag value when logging errors to the PM log file or as part of the response to a request. While optional, it is a good idea to set this attribute to a meaningful value to help track any issues with process management.

status="state"

Required: false
Default: enabled
Valid Values: critical, enabled, or disabled

A module may be enabled, in which case PM loads in its shared library when it starts and calls the module's initialization functions, or disabled in which case the module entry is completely ignored. If the module process-types are configured in the opmn.xml file they must also be disabled. The critical state is the same as enabled, except that OPMN terminates with a fatal error code if the module initialization fails.

cron="interval"

Required: false
Default: none
Valid Values: An integer.

Specify the interval in seconds between calls to the module's cron callback function. Configuring a cron interval for a module that does not support the cron callback is not allowed. Unless you have designed the module, you should neither add nor alter this attribute.

module-data

Required: false
Default: none
Parents: <module>, <ias-instance>, <ias-component>, <dependencies>, <process-set>
Attributes: none

The module-data blocks are used to define module specific name-value pairs that are meaningful only to a specific module. Each module-data block is organized into categories, which contain the name-value data pairs.

The module-data blocks can be defined for multiple elements within the opmn.xml file, and OPMN creates an aggregate module-data block at the process-set level that contains all values defined at or above it. If multiple definitions exist in this hierarchy with the same category id and data id, the value defined at the lowest level is used.

Table 6-5 illustrates the module-data defined at each level in the hierarchy (with the highest level displayed at the top) and the resultant union at the process-set level of all of the module-data definitions:

Table 6-6 module-data Hierarchy

</category>
<category id="CatB">
   <data id= "DataBA" value="baba"/>
   <data id= "DataBB" value="bbbb"/>
</category>

category

Required: true
Default: none
Parents: module-data
Attributes: id

The category element is an organizational level within a module-data block.

id="id"

Required: true
Default: none
Valid Values: A string.

This id string identifies a data category. Each category id within a single module-data block must be unique, but multiple module-data blocks may contain the same data category ids, in which case the categories are considered to be related.

data

Required: true
Default: none
Parents: <category>
Attributes: id, value, process-conversion

A data name value definition within a module-data category.

id="id"

Required: true
Default: none
Valid Values: A string.

This string identifies a data attribute. Each data id within a single category must be unique, but multiple categories may contain the same data identifications. Data elements with the same identification as other data elements, that are defined in different categories with the same identification, are related.

value="value"

Required: true
Default: none
Valid Values: A string.

The value string associated with the data element id. Any environment variable defined anywhere within the process-set (any level at or above the process-set) in which the data value is defined (again, any level at or above the process-set) referenced within the value string as $variable or %variable% is expanded to the variable value.

process-conversion="boolean"

Required: false
Default: true
Valid Values: true or false

The process-conversion attribute enables you to set the separator character. By default OPMN converts slashes in the data value string to be those of the directory path separator character for the system on which OPMN is running (on UNIX each \ character is converted to / and on Windows each / is converted to \). Set this attribute to false to disable this conversion.

Note that if process-conversion is true, OPMN uses the ^ character as an escape character to disable process conversion for the following character, and so ^/ on a Windows system yields a "/" in the string. Specify two ^ characters if you need to specify the ^ character in the resultant string: ^^ yields ^.

module-id

Required: true
Default: none
Parents: <module>
Attributes: id

The module-id name defines the type of process and associates the configuration with a process module.

This identifier is used by each process-type to specify which module supports it. A module may be configured with multiple module-ids.

id="module-id"

Required: true
Default: none
Valid Values: A string.

ias-instance

Required: true
Default: none
Parents: <process-manager>
Attributes: id

The configuration definitions for an Oracle instance. Only one ias-instance is supported for each OPMN.

id = ias-instance-id; name = ias-instance-name

id="ias-instance-name"

Required: true
Default: none
Valid Values: A string.

The string specifies the ias-instance id.

name="ias-instance-name"

Required: false
Default: ias-instance-id
Valid Values: A string.

The name string specifies the ias-instance name, and it is this value that is used to identify the Oracle instance.

environment

Required: true
Default: Refer to the following paragraph.
Parents: <ias-instance>, <ias-component>, <process-type>, <process-set>
Attributes: none

Like module-data blocks, environment blocks can be defined for multiple elements within the opmn.xml file, and OPMN creates an aggregate environment block at the process-set level that contains all values defined at, or above it. If multiple definitions exist in the hierarchy with the same id, the value defined at the lowest level is used.

OPMN provides a default set of environment variables for each managed process, and a set of Java system properties for managed Java processes.

variable

Required: true
Default: none
Parents: <environment>
Attributes: id, value, append, process-conversion

The variable element defines the environment variable name and value.

id="id"

Required: true
Default: none
Valid Values: A string.

The id is the environment variable name. An environment id may be duplicated within an environment block, with the last defined value taking priority over earlier definitions. The same environment id may be defined within environment blocks for different elements, and the value defined at the lowest level takes priority over values defined at higher levels.

value="value"

Required: true
Default: none
Valid Values: A string.

The environment value. Environment variables referenced within the value string as $variable or %variable% is expanded to the variable value. The same environment variable may reference itself to use a definition defined at a higher level, or earlier within this same environment block or from the environment of OPMN.

You may use the Linux shell syntax for referencing an environment variable, $variable or ${variable}, or the Microsoft Windows format %variable%. Referenced variables that have not been defined remain in place as referenced, and so value="_notdefined_" would remain unchanged.

For example, the following environment block yields a value for accumulate of "foobar".

<environment>
   <variable id="accumulate" value="foo">
   <variable id="accumulate" value="${accumulate}bar">
</environment>

append="boolean"

Required: false
Default: false
Valid Values: true or false

You can force OPMN to append the new environment variable value to the previously defined value, with the system library delimeter placed in between the two values (':' for Linux and ';' for Microsoft Windows) by specifying a value of true for this attribute. This is useful when assembling a value for a variable such as CLASSPATH.

For example, the following environment block yields a value for CLASSPATH of "/foo:/bar" on a Linux system.

<environment>
   <variable id="CLASSPATH" value="/foo">
   <variable id="CLASSPATH" value="/bar" append="true">
</environment>

process-conversion="boolean"

Required: false
Default: true
Valid Values: true or false

ias-component

Required: true
Default: none
Parents: <ias-instance>
Attributes: id, id-matching, status, type

An ias-component is a logical grouping of process-type for administrative purposes.

id="component-id"

Required: true
Default: none
Valid Values: a string

The id attribute uniquely identifies the ias-component within the ias-instance.

id-matching="boolean"

Required: false
Default: false
Valid Values: true or false

By default OPMN requests that do not specify ias-components match all configured ias-components, unless the id-matching attribute for a component is set to true, in which case the request must explicitly include the ias-component id in order to affect the ias-component or any process-type or process-set configured for that ias-component.

status="state"

Required: false
Default: enabled
Valid Values: enabled or disabled

An ias-component may be enabled, in which case OPMN parses all of its configured attributes and elements and enables requests to operate upon it, or disabled, in which case the ias-component entry is completely ignored.

type="component-type"

Required: false
Default: none
Valid values: A string.

The type attribute allows you to specify a relationship among ias-components within the same ias-instance.

When configured the component-type is used for the value of the per process COMPONENT_TYPE environment variable (or the oracle.component.type system property for Java processes), and for the type element of the paths specified by COMPONENT_CONFIG_PATH and COMPONENT_LOG_PATH (oracle.component.configpath and oracle.component.logpath). If component-type is not configured, then the process-type id attribute is used in the composition of these strings.

dependencies

Required: false
Default: none
Parents: <ias-component>, <process-type>, <process-set>
Attributes: none

OPMN uses dependencies to determine if a process should be started or not. Like module-data and environment block, dependencies blocks can be defined for multiple elements within the opmn.xml file, and OPMN creates an aggregate dependency list at the process-set level that contains all dependencies defined at or above it. If duplicate dependencies are defined at different levels, then duplicate checks on that dependency is made before starting a process. OPMN creates an aggregate dependency list at the process-set level that contains all dependencies defined at or above it. If duplicate dependencies are defined at different levels, then duplicate checks on the dependency is made before starting a process.

There are two primary types of dependencies: external and internal. External dependencies are for those resources not managed by OPMN. For example: Fusion Middleware Control Console.

An external program is executed by OPMN to perform the check on the resource. Internal dependencies are for system component processes (unit), which may include processes managed on a remote OPMN.

OPMN maintains a cache of dependency states which contains the last known state of each dependency, and the time it was last checked. A cache-timeout parameter for each dependency enables users to specify how long to use its state in the cache, or if it should be used at all. Similarly, a general timeout parameter for each dependency determines how long OPMN waits for a status update from that dependency before aborting the dependency check and the process start.

OPMN checks dependencies in the order in which they are declared. The traversal of the list of dependencies concludes either with the full sequence of successful checks, the dependency is available, or the first check failure, the dependency is not available, or the dependency check timed out.

database

Required: false
Default: none
Parents: <dependencies>
Attributes: db-connect-info, infrastructure-key, timeout, cache-timeout

The database element specifies the database to check. Either db-connect-info or infrastructure-key is used to identify the database.

db-connect-info="connect"

Required: true if infrastructure-key is not specified.
Default: none
Valid Values: A string

The db-connect-info attribute is the string required to connect to the database. The string can be in either of the following formats:

<host>:<port>/<service name>

(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp) (HOST=<host>) (PORT=<port>)) (CONNECT_DATA=(SERVICE_NAME=<service name>)))

For example:

pdsundev7:1521/asdb.us.oracle.com

infrastructure-key="key"

Required: true if db-connect is not specified.
Default: none
Valid Values: A string

The infrastructure key attribute is required to identify the database.

timeout="depend-timeout"

Required: false
Default: 1200
Valid Values: An integer

The timeout attribute specifies in seconds how long OPMN waits for a dependency check to complete. If the check takes longer than the configured timeout, then OPMN considers the check to have failed.

cache-timeout="cache-timeout"

Required: false
Default: 600
Valid Values: An integer

The cache-timeout attribute specifies how long in seconds OPMN uses the current "up" status for the dependency entry in the cache. If the last successful dependency check was within the prescribed number of seconds from the current check, then the dependency check is instantly flagged as successful, otherwise another dependency check is performed. Note that the cache-timeout is only for the last successful check of the dependency, and if the previous check failed, another access of the dependency is performed for this check. A value of 0 indicates OPMN always performs the check.

OID

Required: false
Default: none

managed-process

Required: false
Default: none
Parents: <dependencies>
Attributes: ias-instance, ias-component, process-type, process-set, autostart, autostop, timeout, cache-timeout

The managed-process attribute specifies the managed process to check. A process for process-type or process-set does not start unless the specified dependency managed process is active. Circular dependencies are detected and rejected for local managed processes, but not for remote managed processes; this may result in a dependency check deadlock, which times out.

ias-instance="ias-instance-id"

Required: false
Default: The ias-instance of the current process-type or process-set.
Valid Values: A string

The ias-instance for the managed process dependency. If the specified ias-instance is not managed by the current OPMN, it is assumed to be a remote managed process dependency.

The cache-timeout attribute is only used for a process managed by a remote OPMN. The cache-timeout attribute specifies how long in seconds OPMN uses the current "up" status for the dependency entry in the cache. If the last timeout dependency check was within the prescribed number of seconds from the current check, then the dependency check is instantly flagged as successful, otherwise OPMN performs another dependency check. Note that the cache-timeout is only for the last successful check of the dependency, and if the previous check failed, OPMN access of the dependency is performed for this check. A value of 0 indicates OPMN always performs the check.

Note:

The cache-timeout is only for the last successful check of the dependency, and if the previous check failed, OPMN performs another dependency check.

process-type

Required: true
Default: none
Parents: <ias-component>
Attributes: id, module-id, status, working-dir

A process-type is a grouping of process-sets that are supported by the same module.

id="process-type-id"

Required: true
Default: none
Valid Values: a string

The id attribute uniquely identifies the process-type within the ias-component.

Required: true
Default: none
Valid Values: a string

The module-id attribute must map directly map to the module-id attribute that supports the process-type.

status="state"

Required: false
Default: enabled
Valid Values: enabled or disabled

A process-type may be enabled, in which case OPMN parses all of its configured attributes and elements and enables requests to operate upon it, or disabled, in which case the process-type entry is completely ignored and treated as if it were not listed in the opmn.xml file.

working-dir="path"

Required: false
Default: none
Valid Values: A path name

The working-dir path name specifies the working location that is set for managed processes created by the process-type element. If a process-set also defines a working-dir attribute, then the process-set path name takes precedence over the process-type path name.

event-scripts

Required: false
Default: none
Parents: <process-type>, <process-set>
Attributes: none

A configured event script is executed when a specific process related event has occurred. OPMN waits until the script completes or times out before proceeding with the next action for the process.

Table 6-9 shows event script arguments.

Table 6-9 Event Script Arguments

Option Name
Option Argument
Description

-timeStamp

<time>

An integer value for the current time on the system (in seconds).

-instanceName

<instance-name>

The instance-name of the managed process.

-componentId

<component-id>

The component-id of the managed process.

-processType

<process-type-id>

The process-type of the managed process.

-processSet

<process-set-id>

The process-set of the managed process.

-processIndex

<index>

The process-index of the managed process.

-stderrFoot 1 

<path>

The path name for the stderr file pointer of the process.

-stdoutFootref 1

<path>

The path name for the stdout file pointer of the process. Note: this argument is only given for a pre-start script if the start is part of a process restart request.

-reason

<reason>

A string indicating the reason script was executed. The http_request indicates the process action is the result of the user HTTP request to OPMN. The non_http_request indicates the process action was initiated by OPMN itself.

-pidFoot 2 

<process-id>

The operating system integer value given for the process-id.

-startTimeFootref 2

<time>

An integer value for the system start time of the process (in seconds).

Footnote 1 This argument is only given for a pre-start script if the start is part of a process restart request. The pre-start event is triggered only prior to performing a start. A restart operation may be composed of a stop operation followed by a start operation. A start operation can occur as an operation all by itself or as a sub-operation of a restart.

Footnote 2 This argument is only available with pre-stop or post-crash event scripts.

pre-start

Required: false
Default: none
Parents: <event-scripts>
Attributes: path

OPMN runs the pre-start script after any configured dependency checks have been performed (and passed) and before the process is actually started. The timeout for the pre-start script is the timeout value configured for starting the process itself, and any time consumed by the execution of this script counts toward the process start timeout. If the script times out, the process is not started and any associated HTTP request fails.

Be cautious when you execute any OPMN process requests such as start, stop or restart within an event script. These requests are serialized at the process-set level. If the script invokes a request on a process-set on which the current request (or another already queued request) is operating, then the script hangs until it times out.

path="path"

Required: true
Default: none
Valid Values: The path name to the executable script.

The path name must specify either an executable program for which OPMN has execute permission, or a script file for which OPMN has both read and executable permission.

pre-stop

Required: false
Default: none
Parents: <event-scripts>
Attributes: path

OPMN runs the specified script before stopping the associated process. The timeout for the script is the value configured for stopping the process itself. Any time consumed by the execution of the script counts toward the process stop timeout. If the script times out, any associated HTTP request fails. However, OPMN proceeds with stopping the process.

Be cautious when you execute any OPMN process requests such as start, stop, or restart. These requests are serialized at the process-set level. If the script invokes a request on a process-set on which the current request (or another already queued request) is operating, then the script hangs until it times out.

path="path"

Required: true
Default: none
Valid Values: The path name to the executable script.

The path attribute must specify either an executable program for which OPMN has execute permission, or a script file for which OPMN has both read and executable permission.

post-crash

Required: false
Default: none
Parents:<event-scripts>
Attributes: path

OPMN runs the specified script after the associated process has terminated unexpectedly. The timeout for the script is the timeout value configured for stopping the process itself. After the script has terminated OPMN schedules a replacement of the terminated process.

Be cautious when you execute any OPMN process requests such as start, stop or restart. These requests are serialized at the process-set level. If the script invokes a request on a process-set on which the current request (or another already queued request) is operating, then the script hangs until it times out.

path="path"

Required: true
Default: none
Valid Values: The path name to the executable script.

The path attribute must specify either an executable program for which OPMN has execute permission, or a script file for which OPMN has both read and executable permission.

interval="interval"

Required: false
Default: 20
Valid Values: An integer

The interval attribute is the interval, in seconds, between each ping of a managed process.

port

Required: false
Default: none
Parents: <process-type>
Attributes: id, range

The port element provides a port management mechanism for modules to use. Each module uses the ports configured with id.

id="id"

Required: true
Default: none
Valid Values: A string

The id attribute identifies the range of ports for the process-type. Each module has its own list of required or optional port ids.

range="range"

Required: true
Default: none
Valid Values: A port range

The port range specifies which ports to use for the id.

Upon request from a module for a port number from the id, OPMN checks if a port in the range has been bound on the local system, and if it has not, it returns that port number back to the module. Syntax of the port range is a comma separated list of individual port numbers or a low-high range specification.

Examples:

Specify ports 5555, 6666, 7777, 8888, and 9999:

range="5555,6666,7777,8888,9999"

Specify ports 4000 through 4250 (inclusive):

range="4000-4250"

Specify ports 7000 through 7049, 7775, 7785, and 8050 through 8099:

process-set

Required: false
Default: id="component-id" numprocs="1"
Parents: <process-type>
Attributes: id, restart-on-death, numprocs, minprocs, maxprocs, status, working-dir, parallel-requests

A process-set is the abstraction of a process within OPMN. All module-data, environment variables, and other configuration parameters are resolved into their final values at the process-set level.

If a process-set is not configured, then one is automatically created using the same id as the ias-component and numprocs of 1.

id="process-set-id"

Required: true
Default: none
Valid Values: A string

The id attribute uniquely identifies the process-set within the process-type.

restart-on-death="boolean"

Required: false
Default: true
Valid Values: true or false

If a managed process terminates unexpectedly, that is, not stopped by a request, then OPMN will not automatically restart it. To disable automatic restarting of terminated managed processes set the attribute to false.

numprocs="num"

Required: true unless minprocs is configured; otherwise false
Default: none
Valid Values: An integer

Specifies the number of processes for OPMN to start for the process-set.

minprocs="min"

Required: true unless numprocs is configured; otherwise false
Default: none
Valid Values: An integer

Specifies the default number of processes for OPMN to start for this process set. If minprocs is configured, then maxprocs must be set with a value greater than or equal to the value for minprocs. If minprocs and maxprocs are configured, a specific number of processes may be given in an OPMN request for this process set. This attribute may not be specified if numprocs has been configured.

maxprocs="max"

Required: true if minprocs is configured; otherwise false
Default: none
Valid Values: An integer

The maxprocs attribute must be specified if minprocs has been configured, but cannot be specified if numprocs has been configured.

status="state"

Required: false.
Default: enabled
Valid Values: enabled or disabled

A process-set may be enabled, in which case OPMN parses all of its configured attributes and elements and enables requests to operate upon it, or disabled, in which case the process-set entry is complete ignored and treated as if it were not even listed in the opmn.xml file.

working-dir="path"

Required: false.
Default: ORACLE_INSTANCE
Valid Values: A path name

The working-dir path name specifies the working directory set for the managed processes created that belong to the process-set.

parallel-requests="boolean"

Required: false
Default: false
Valid Values: true or false

OPMN serializes requests at the process-set level, such that only one request can execute on a given process-set at a time: each subsequent request must wait until the previous request completes before it can execute. This default behavior is disabled for a process-set when parallel-requests is set to true.

Note:

When the parallel-requests attribute is enabled OPMN performs no serialization on requests for the process-set at all, which means conflicting requests may be issued and execute at virtually the same time, thus leaving processes in the process-set in unpredictable states; therefore when parallel-requests is set to true you must verify that conflicting requests are not issued at the same time for the process-set (this includes requests with implicit wild-cards for matching process-sets).

launch-targets

Required: false
Default: none
Parents: <process-manager>
Attributes: none

The launch-targets block is composed of a list of launch-target definitions. There can be only one launch-targets block.

launch-target

Required: false
Default: none
Parents: <launch-target>
Attributes: id

The definition of a process which OPMN starts via the launch request.

id="id"
Required: true

Default: none
Parents: <launch-target>
Attributes: path

The executable path for the launch-target. Only one exec element may be configured per launch-target.

Any additional arguments passed in via the launch request are passed in after the configured arguments.

value="argument"

Required: true
Default: none
Valid values: A string.

Specify a single argument for the executable; spaces are not argument delimeters-use multiple argument elements to define multiple arguments.

timeout

Required: false
Default: 120
Parents: <launch-target>
Attributes: value

The timeout used for each io made from the launch request thread. Only one timeout element may be configured per launch-target.

A Configuring Custom Process

This chapter describes custom process configuration in the OPMN opmn.xml file.

It features the following topics:

Custom Process Module Configuration

Custom Process Minimum Configuration

Custom Process Complete Configuration

Custom Process Attribute Descriptions

A.1 Custom Process Module Configuration

The following lines load and identify the custom process module. Management of custom processes by the process module are identified by the module id.

<module path="ORACLE_HOME/opmn/lib/libopmncustom.so">
   <module-id id="CUSTOM" />
</module>

A.2 Custom Process Minimum Configuration

The following lines represent the minimum configuration for a custom process. Default values are assigned to all other configuration elements and attributes for the custom process.

<ias-component id="Custom">
   <process-type id="Custom" module-id="CUSTOM">
   <process-set id="Custom" numprocs="1">
      <module-data>
         <category id="start-parameters">
            <data id="start-executable" value="Your start executable here" />
         </category>
      </module-data>
   </process-set>
   </process-type>
</ias-component>

A.3 Custom Process Complete Configuration

Example A-1 show a complete configuration for a custom process. It contains all possible configuration elements and attributes for a custom process.

A custom process can be part of any other system component. In such cases, the process-type element in Example A-1 must be part of the component configuration.

A.3.1 Ping

The custom module provides the framework for pinging a custom process in one of two ways:

HTTP ping

script ping

The type of ping can be configured by specifying the appropriate data in the ping-parameters category. The sample configuration example Example A-1 shows a custom process using HTTP ping. Example A-1 is an example of script ping that you can substitute into the component configuration.

Example A-1 Custom Process Complete Configuration

<ias-component id="Custom" status="enabled" id-matching="false">
   <environment>
      <variable id="TEST_ENV_VARIABLE" value="/your/test/value"
      append="false"/>
   </environment>
   <process-type id="Custom" module-id="CUSTOM">
   <process-set id="Custom" restart-on-death="true" numprocs="1">
      <module-data>
         <category id="start-parameters">
            <data id="start-executable" value="Your start executable here" />
            <data id="start-args" value="Your start args here" />
            <data id="append-req-args" value="Arguments appended to the end of the
             start command"/>
            <data id="java-proc" value="true"/>
         </category>
         <category id="stop-parameters">
            <data id="stop-executable" value="Your stop executable here" />
            <data id="stop-args" value="Your stop args here" />
            <data id="append-req-args" value="Arguments appended to the end of the
             stop command"/>
         </category>
         <category id="restart-parameters">
            <data id="restart-executable" value="Your restart executable here"/>
            <data id="restart-args" value="Your restart args here" />
            <data id="append-req-args" value="Arguments appended to the end of the
             restart command"/>
         </category>
         <category id="ping-parameters">
            <data id="ping-type" value="http" />
            <data id="ping-url" value="/your/ping/url" />
            <data id="ping-host" value="abc.company.com" />
            <data id="ping-port" value="7777" />
            <data id="ping-limit" value="3" />
            <data id="ping-timeout" value="300" />
         </category>
         <category id="ready-parameters">
            <data id="use-ping-for-ready" value="false" />
         </category>
      </module-data>
   </process-set>
   </process-type>
</ias-component>

Pinging with a script can be configured as shown in Example A-2.

Example A-2 Ping Type Script

<category id="ping-parameters">
   <data id="ping-type" value="script" />
   <data id="script-executable" value="Ping executable here" />
   <data id="script-args" value="Ping arguments here " />
</category>

You can use pinging (when available) for determining the readiness of a process. This indicates that OPMN needs confirmation that a managed process has started successfully after creation. Processes can inform OPMN of their ready status in various ways. The custom module enables these processes to communicate readiness through pinging. If you configure pinging for a custom process, you can also use this mechanism to determine if the process is ready. You can choose not to configure any mechanism for determining readiness in which case the custom module just assumes that the process started successfully.

Note:

The ready ping, if configured, is created soon after the process is created. If the process takes a while to initialize and respond to pings, then using pinging for determining readiness is not appropriate. This is because if the process does not respond to the "ready ping", OPMN determines that the process did not start correctly and stop it.

A.4 Custom Process Attribute Descriptions

This section describes the attributes that are specific for a custom process. This section also provides attribute descriptions of the attributes.

The custom process attributes are described with the following format:

Title: This is the attribute name and value being defined. For example, id="Custom".

Required: This field defines whether or not the attribute is required in the component definition.

Default: This defines the default value assigned to the attribute. The default value appears in the installed version of the opmn.xml file or is assigned internally if the attribute is not present.

B.1 Problems and Solutions

This section describes some of the common problems encountered when using OPMN. It features the following topics:

System Process Does Not Start

Determining if System Processes are Dying or Unresponsive

opmnctl Command Execution Times Out

System Component Automatically Restarted by OPMN

Unexpected opmnctl start Behavior

Disabled Element in the opmn.xml File

Unable to Start OHS

Unable to Stop Component

globalInitNLS Error

OPMN Start Up Consumes CPU Processing Capability

Error Messages During Start-up of OPMN

Increasing Size of opmn.log File

Cleanup of Oracle Instance or Component If It is in a Bad State

B.1.1 System Process Does Not Start

Problem

Unable to start a system process using OPMN.

Solution

Try the following if you are unable to start a system process using OPMN:

Verify and if necessary, correct, the command input. Confirm the spelling and choice of option for the command you are entering.

Note:

Do not use command line scripts or utilities from previous versions of Oracle Application Server or Oracle Fusion Middleware for starting OPMN or system components.

Most managed processes now have their own log directory, and OPMN uses that if it is present as the location for the process log file.

ORACLE_INSTANCE/diagnostic/logs/<type>/<ias-component>/

If the default directory for a managed process does not exist, OPMN places the console log in its own log directory:

ORACLE_INSTANCE/diagnostics/logs/OPMN/opmn/

For example, the standard output log for Oracle HTTP Server may be ORACLE_INSTANCE/diagnostics/logs/OHS/ohs1/console~OHS~1.log

Verify the dependency requirements for the system process you are attempting to start.

Verify the element values for the system component in the opmn.xml file. Use the opmnctl validate command to verify configuration of opmn.xml file. You may have mis-configured the opmn.xml for the system component you are attempting to start.

B.1.2 Determining if System Processes are Dying or Unresponsive

Problem

Your system processes are dying or unreachable.

Solution

If your system processes are dying or unreachable:

Review the system component specific output in the ORACLE_INSTANCE/diagnostics/logs/OPMN/opmn.

Look at the ORACLE_INSTANCE/diagnostics/logs/OPMN/opmn/opmn.log for system processes. Look for process crashed or process unreachable messages. OPMN automatically restarts system processes that die or become unresponsive.

See Also:

Section B.2.1 for more information about OPMN log files

Create event scripts for any pre-stop or post-crash events. The event scripts could be used to create a specific log file or send you an email about a failure.

See Also:

Section B.2.4 for information about troubleshooting with event scripts

B.1.3 opmnctl Command Execution Times Out

Problem

The time it takes to execute an opmnctl command is dependent on the type of system process and available computer hardware. Because of this the time it takes to execute an opmnctl command may not be readily apparent.

Solution

To verify successful execution of the opmnctl command, try the following:

Increase the start element timeout attribute for the component that is not starting. Set the timeout in the opmn.xml file at a level that allows OPMN to wait for process to come up. This functionality is available with the startproc command which starts all the relevant processes configured in the opmn.xml file.

Check the start element in the opmn.xml file and change the retry attribute to a higher increment of time.

Look at the ORACLE_INSTANCE/diagnostics/logs/ for the system process that is not starting.

Review the component-specific log file for the system component that is not starting. For example, ORACLE_INSTANCE/diagnostics/logs/OHS/ohs1/console~OHS~1.log.

See Also:

Chapter 6 for more information about the common configuration of the opmn.xml file

B.1.4 System Component Automatically Restarted by OPMN

Problem

A system component is automatically restarted by OPMN.

Solution

If a system component is automatically restarted by OPMN, try the following:

Review the message for the system component in the ORACLE_INSTANCE/diagnostics/logs/OPMN/opmn/opmn.log file.

Verify that the ping timeout for the system component is sufficient. A system component that receives a lot of activity may require an increase in the length of time for the timeout. Increase the ping timeout element in the system component opmn.xml file.

B.1.5 Unexpected opmnctl start Behavior

Problem

Occasionally, there is unexpected behavior when you use the opmnctl start command to start OPMN; either only OPMN is started or OPMN makes a best effort to start system processes. Typically, this unexpected behavior is due to turning-off or rebooting your computer without first shutting down OPMN. When you restart your computer, all system component processes are started.

Solution

Oracle recommends that you shutdown OPMN before shutting down your computer. Use the opmnctl stopall command to stop OPMN and system component processes.

On the Microsoft Windows operating system, you can use the Windows services control panel to stop OPMN and system components.

Note:

OPMN keeps a record on disk of the expected status of the processes it manages. If a computer goes down while OPMN is running, upon restart OPMN uses the information cached on disk and make a best effort attempt to automatically restart all processes that were running at the time the system went down. This may catch some users off guard who start only OPMN and notice that processes managed by OPMN have also been started even though an explicit request to start those processes has not been issued.

You can suppress this automatic process recovery by setting the following attribute for the process-manager element in the opmn.xml file:

restore-procs-on-reboot="true"

B.1.6 Disabled Element in the opmn.xml File

Problem

Unable to start an system process.

Solution

If you are unable to start an system process, check if an element in the system opmn.xml file is disabled. If an element in the opmn.xml file is disabled OPMN generates an output message of "Missing" or "Disabled".

B.1.7 Unable to Start OHS

Problem

If you have multiple Oracle Fusion Middleware installations on one host and you start them at the same time (for example, to start a farm), OPMN may become unresponsive. You may receive an error message such as:

"failed to restart a managed process after the maximum retry limit"

This may occur when two Oracle instances on the same host use the same ports. An OHS component in one Oracle instances is trying to use the same port as an OHS component in a different Oracle instance. When two OPMN processes on a host start at the same time, there is no coordination between them on port usage.Port allocation for all OHS instances within Oracle Fusion Middleware is controlled by OPMN; there can be overlapping port ranges within a single opmn.xml file. However, when two OPMN processes on a host start at the same time, there is no coordination between them on port usage.

Solution

Make sure the ports assigned to OHS in each Oracle instance are unique and not used by any other process on the computer.

It is also recommended that you increase the maximum number of retries for starting Oracle instances. If you have identical port ranges in two Oracle homes and increase the number of times OPMN attempts to restart a process, OPMN eventually selects a port that works. This technique ultimately does not eliminate the problem, because there is the possibility that OPMN will not find a port that works in the number of port connection attempts that you have specified in the opmn.xml file.

B.1.8 Unable to Stop Component

Problem

If you are unable to stop system components using the opmnctl stop or opmnctl stopall commands, the component or process was most likely not started using OPMN. The component or process might have been started using a startup script or utility.

Solution

System components should never be started or stopped manually. Do not use command line scripts or utilities from previous versions of Oracle Application Server or Oracle Fusion Middleware for starting and stopping system components.

Use the Fusion Middleware Control Console and the opmnctl command line utility to start or stop system components.

See Also:

Chapter 5 for OPMN command-line examples

B.1.9 globalInitNLS Error

Problem

You may receive a globalInitNLS error when executing the opmnctl command. The following error message is displayed:

"globalInitNLS: NLS boot file not found or invalid -- default linked-in boot block used XML parser init: error 201."

Solution

This error occurs when the ORA_NLS33 environmental variable is set. This environmental variable should not be set.

B.1.10 OPMN Start Up Consumes CPU Processing Capability

Problem

On some computers, when OPMN starts up, it consumes large amounts of CPU processing capability. This can vary from approximately 50% to 60% of your computer's CPU processing capabilities. In affected computers, the OPMN CPU processing consumption continues until OPMN is shutdown.

Solution

One of the possible cause for the excessive CPU processing consumption is the installation environment used multibyte text character sets such as Japanese.

B.1.11 Error Messages During Start-up of OPMN

Problem

When trying to start OPMN using the opmnctl start or opmnctl startall commands you receive the following error messages:

pingwait exits with 1220384

or

pingwait exits with 1220396

These error messages are generated when there are syntax errors in the ORACLE_INSTANCE/config/OPMN/opmn/opmn.xml that need to be corrected.

Solution

If you encounter these error messages do the following:

run the following command (with the complete directory path to the opmn.xml file):

opmnctl validate opmn.xml

remove all empty tags from the opmn.xml file.

B.1.12 Increasing Size of opmn.log File

Problem

If you install Oracle Fusion Middleware on a computer that contains a previous installation of the Oracle Database or Oracle Fusion Middleware, the ORACLE_INSTANCE/diagnostics/logs/OPMN/opmn/opmn.log file increases in size to over 4100000 KB due to continuous logging. The file may contain the following error message:

"[ons-connect] Local connection 127.0.0.1,6100 invalid form factor "

Solution

Change the request port for the opmn.xml file to a value greater than the 6100. For example:

<port local ="6202" remote="6302" request="6105"/>

This error is most often caused by a conflict with a previous Oracle Database or Oracle Fusion Middleware installation on the same computer. The above occurs due to entries in the oraInventory directory of an existing or previous installation of Oracle Database or Oracle Fusion Middleware.

B.1.13 Cleanup of Oracle Instance or Component If It is in a Bad State

Problem

Your Oracle instance or component is providing some incorrect defaults for your opmnctl commands.

Solution

Use the opmnctl deleteinstance command with the -force true option to clean up the Oracle instance or component.

For example:

opmnctl deleteinstance -oracleInstance /scratch/bsong/demo1/inst1 -instanceName inst1 \ -adminHost myhost -adminPort myport -force true

Use discretion when utilizing the -force option. When you use this option with the opmnctl deleteinstance command a number of safeguards that protect the integrity of the Oracle instance or component are overruled. Misuse of this option may produce undesirable results.

Explicitly listing all applicable arguments (for example, oracleInstance, instanceName, adminHost, and adminPort) with the opmnctl deleteinstance command can help attain the desired results.

During the course of executing cleanup, a forced command displays warnings or exceptions consistent with the damaged state of the Oracle instance or component. These warning are provided as visual feedback for the inconsistencies encountered and do not necessarily indicate that further corrective action is needed.

B.1.14 Path Arguments Containing Quotation Marks on Windows Operating Systems

Problem

The path argument provided to opmnctl contains quotes (") and everything that appears after the first quote (including other flags intended for opmn) is included in the ORACLE_Instance name. This is a Windows operating system issue only.

For example:

opmnctl createinstance -oracleInstance %T_WORK%\"inst1" -adminRegistrationOFF

In this example, the name of the ORACLE_INSTANCE will be:

inst1-adminRegistration OFF

Solution

The quotes must encompass the entire argument or the command.

For example:

opmnctl createinstance "%T_WORK%\inst1" -adminRegistration OFF

In the corrected example, the name of the ORACLE_INSTANCE will be:

inst1

B.2 Diagnosing OPMN Problems

There are several methods for troubleshooting any problems you may have using OPMN:

OPMN log Files

opmnctl debug

Oracle Enterprise Manager Fusion Middleware Control Console

Troubleshooting with Event Scripts

opmn.xml Environment Variables

B.2.1 OPMN log Files

The OPMN log files enable you to troubleshoot difficulties you might have in execution and use of OPMN and system component processes. OPMN and system component processes generate log files during processing. You can review the following generated log files to verify successful or unsuccessful execution of an OPMN command:

ORACLE_INSTANCE/diagnostics/OPMN/opmn/opmn.out: contains the standard output (stdout) and standard error (stderr) logs of OPMN. Also referred to as the OPMN "console log". After a certain point in OPMN initialization, nothing else is written to this file. Only a small set of messages ever appears in this file; therefore, this file may not be present if you conduct a search through the log file directories.

ORACLE_INSTANCE/opmn/logs/opmn.log: tracks command execution and operation progress. It contains messages useful for monitoring the operations of the OPMN server. Output written to the opmn.log file contains the exit status of a child OPMN process. A status code of 4 indicates a normal reload of OPMN. All other status codes indicate an abnormal termination of the child OPMN process. The opmn.log file is configured using the <log> attribute in the opmn.xml file. Refer to Chapter 6 for more information about the common configuration of the opmn.xml file.

ORACLE_INSTANCE/diagnostics/logs/OPMN/opmn/debug.log: contains OPMN debug log messages (English only) for ONS and PM. Review the error codes and messages that are shown in the debug.log file. The PM portion of OPMN generates and outputs the error messages in this file. The debug.log file tracks command execution and operation progress. The level of detail that gets logged in the debug.log can be modified by configuration of the <debug> element in the opmn.xml file.

Refer to Chapter 6 for examples of debug levels.

Use the debug.log file to debug the ONS portion of OPMN or for early OPMN errors. The ONS portion of OPMN is initialized before PM. Therefore, errors that occur early in OPMN initialization shows up in the debug.log file.

Enable usage of the debug.log file only after conferring with Oracle Support. The debug.log file is used by Oracle Support to debug and diagnose OPMN issues. Messages that are contained in the debug.log file are typically not readily comprehensible to the user.

B.2.1.1 opmn.log and debug.log File Rotation

OPMN enables you to rotate the opmn.log and debug.log files based on parameters of file size, specific time, or both, as a basis for file rotation. You can enable rotation by configuring the rotation-size and rotation-hour attributes of the <log> and <debug> tags in the opmn.xml file. When either the log file grows to a specified size or the specified time of the day is reached, or a combination of both parameters, the OPMN logging mechanism closes the file, rename the file with a unique time stamp suffix, and then create a new opmn.log or debug.log file.

The OPMN console log file (opmn.out) is not rotated; this file is typically very small in size. Once OPMN surpasses an point of initialization, output is no longer generated to the console output file; therefore, only a relatively small set of messages appears in this file.

B.2.1.2 Process Console log File Rotation

At process startup, before handing off an existing console log file to a managed process, OPMN checks the size against a configured limit (rotation-size attribute of the <log> tag). If the file size exceeds the limit, OPMN renames the existing file to include a time stamp, and then create a new file for the managed process. If the rotation-size attribute is not configured, OPMN is not able rotate the process console log file.

B.2.2 opmnctl debug

Use the opmnctl debug command to verify the status of an system process and whether any actions are pending. This command generates output that can be used in conjunction with contact to your local Oracle support to diagnose your OPMN problem.

The syntax for the opmnctl debug command is:

opmnctl debug [comp=pm|ons] [interval=<secs> count=<num>]

Output is generated following execution of the opmnctl debug command. Oracle recommends that you contact Oracle support to use the generated output to assist in diagnosis of your problem.

The attributes (<attr>) name for this command are either comp, interval, or count. The value for comp can be either ons or pm, representing ONS and PM, respectively. If comp is not specified, then both ons and pm debug information is reported. For example, the following command outputs debug information for ONS.

opmnctl debug comp=ons

You can specify the interval in seconds and number of requests sent to OPMN to assist in the debugging process. The values of <interval> and <count> must always be specified together. Values for them should be integers greater than 0. For example, the following command, outputs debug information at an interval of 5 seconds 3 times.

opmnctl debug comp=pm interval=5 count=3

Contact your local Oracle support to assist you in using the opmnctl debug command to diagnose your OPMN problem.

B.2.3 Oracle Enterprise Manager Fusion Middleware Control Console

Fusion Middleware Control Console provides a graphical interface that enables diagnosis of system components in your network and enterprise. Fusion Middleware Control Console features a log page. The log page enables you to view all of the system log files in one place and trace problems across multiple log files. Fusion Middleware Control Console uses an API that contacts OPMN.

See Also:

Oracle Fusion Middleware Administrator's Guide

B.2.4 Troubleshooting with Event Scripts

You can create your own event scripts that record system process event activities. You can create a script that records events prior to the start or stop of system processes, as well as an unscheduled system crash.

Refer to the event-scripts element description in Chapter 6.

Example B-1 shows a pre-start event script.

Example B-1 Pre-start Event Script

#!/bin/sh
echo
echo =---===----======---=-----=-----=------======----===---=
echo =---===----===== PRE-START EVENT SCRIPT =====----===---=
echo =---===----======---=-----=-----=------======----===---=

while [ $# -gt 0 ]; do
     case $1 in
        -timeStamp)    timeStamp=$2; shift;;
        -instanceName) instanceName=$2; shift;;
        -componentId)  componentId=$2; shift;;
        -processType)  processType=$2; shift;;
        -processSet)   processSet=$2; shift;;
        -processIndex) processIndex=$2; shift;;
        -stderr)       stderrPath=$2; shift;;
        -stdout)       stdoutPath=$2; shift;;
        -reason)       reason=$2; shift;;
        -pid)          pid=$2; shift;;
        -startTime)    startTime=$2; shift;;
        *) echo "Option Not Recognized: [$1]"; shift;;
        esac
        shift
done

echo timeStamp=$timeStamp
echo instanceName=$instanceName
echo componentId=$componentId
echo processType=$processType
echo processSet=$processSet
echo processIndex=$processIndex
echo stderr=$stderrPath
echo stdout=$stdoutPath
echo reason=$reason
echo pid=$pid
echo startTime=$startTime

Note:

The pre-start event script example, Example B-1, will not work for the Microsoft Windows operating system; however, you can create a script, with a.bat suffix, with similar functionality.

Use the full path to the.bat file when adding the necessary configuration information to the opmn.xml file,.

B.2.5 opmn.xml Environment Variables

The environment variable used to launch OPMN server is not inherited by the system process started by OPMN server. OPMN sets the environment variables at the ias-instance level, with the values extracted either from the ias-instance configuration or from the OPMN run time environment.

In the graphic, if the sequential attribute is set to true, OPMN performs the request upon one process at a time.

As shown in the graphic, all affected managed processes have completed the request.

As shown in the graphic, when the request completes for the first OC4J process, the request starts on the next OC4J process.

As shown in the graphic, by default OPMN issues jobs for all processes in parallel such that they run at the same time (except when honoring dependencies).

OPMN consists of Oracle Notification Server, Oracle Process Manager, and Process Modules

As shown in the graphic, for output, such as debug or log records, each IPv4 identifier is displayed as four, eight bit fields for the address (each a three digit decimal format) and a single 16 bit field for the port (a five digit decimal format).
