Troubleshooting the Oracle Application Server Integration Adapter for IMS/DB

Troubleshooting Oracle Application Server Integration Adapter for IMS/DB can involve checking both Oracle Application Server ProcessConnect and Oracle Connect for IMS/DB.

This chapter contains the following sections:

• Design-Time Troubleshooting

• Troubleshooting the Daemon

Design-Time Troubleshooting

The most common cause of errors when defining the Oracle Application Server Integration Adapter for IMS/DB is incorrect definitions in the delivery channel. If you encounter problems during the modeling phase, check the delivery channel definitions.

See Also: Task: Setting Up the Delivery Channel for details of setting up the delivery channel

The following errors occur during the modeling of interactions, when using a delivery channel that was defined incorrectly.

Specifying the Wrong Adapter Name

The following error occurs when the wrong adapter name is specified in the delivery channel:

Text description of the illustration err3.gif

Check that the name specified for the adapter is the same as the name specified in the delivery channel.

Specifying the Wrong Workspace Name

The following error occurs when the wrong workspace name is specified in the delivery channel:

Text description of the illustration err3a.gif

Check that the name specified for the adapter is the same as the name specified in the delivery channel.

Specifying the Wrong Machine

The following error occurs when the remote machine is specified incorrectly:

Text description of the illustration err1.gif

Check the definition of the remote machine in the delivery channel definition.

Specifying the Wrong Port Number

The following error occurs when the port number to connect to is specified incorrectly:

Text description of the illustration err2.gif

Check the port number defined in the delivery channel. The default port number is 2552.

When the Connection with the OS/390 Machine Is Down

If the delivery channel definitions are correct, the problem is probably with the connection with the OS/390 machine itself. In this case, check that you have a connection to the OS/390 machine in Oracle Studio.

For example you receive a connection timeout error when the daemon is not running on the mainframe:

Troubleshooting the Daemon

A daemon runs on the OS/390 machine. The daemon is responsible for allocating a server process for a client. The daemon resides in a single address space and is executed as a started task.

The daemon authenticates clients, authorizes requests for a server process within a certain server workspace and provides the clients with the required servers. When a client requests a connection, the daemon allocates a server process to handle this connection, and refers the client to the allocated process. This may be a new process (dedicated to this client) or an already-started process. Further communication between the client session and the server process is direct and does not involve the daemon. The daemon is notified when the connection ends and the process is either killed or remains for use by another client

The daemon supports multiple server configurations called workspaces. Each workspace defines accessible data sources, applications, environment settings, security requirements and server allocation rules. The allocation of servers by the daemon is based on the workspace that the client uses to access the data source. Thus, a client can access a data source using one workspace, where a server process is allocated from an existing pool of servers, or the client can access a data source using a different workspace, where a new server process is allocated for each client request.

The daemon loads configuration settings such as various operational parameters as well as the list of workspaces accessible through the daemon.

See Also: Appendix D, "Daemon Configuration Settings" for details about the configuration settings

Troubleshooting the daemon and the communication between Oracle Application Server ProcessConnect and Oracle Connect for IMS/DB is performed using Oracle Studio to monitor the daemon and server activity and control what happens to the daemon and server processes.

This section contains the following sections:

• Starting the Daemon

• Shutting Down the Daemon

• Monitoring the Daemon During Runtime

• Daemon Logs

• Resolving Communication Errors

Starting the Daemon

If for any reason you shut down the daemon, as described in "Shutting Down the Daemon", you can restart the daemon as described in the following task.

Note: The daemon is started on the OS/390 machine only. It cannot be started remotely using Oracle Studio.

Task: Starting the Daemon

Activate INSTROOT.USERLIB(ATTDAEMN) as a started task to invoke the daemon. For example, in the SDSF screen enter the following:

'/s ATTDAEMN'

INSTROOT is the high-level qualifier where Oracle Connect for IMS/DB is installed.

See Also: "Starting the Daemon" for details about the ATTDAEMN JCL

Resolving Communication Errors

When Oracle Studio disconnects from the OS/390 machine, the machine is displayed in Oracle Studio with an X in a red circle. If this situation occurs, try to access the machine later.

The following table describes the various scenarios that may exist when Oracle Application Server ProcessConnect disconnects from the OS/390 machine.

Table 6-2  Scenarios When a Client Is Disconnected

Scenario	Idle (Not Processing a Client Request)	Processing a Client Request
Explicit Disconnect (client explicitly closes connection or client program terminates)	The server is immediately notified of the disconnect and either becomes available for use by another client or terminates (if it is not reusable).	The server does not know that the client has disconnected and continues processing. When processing completes, the server tries to reply to the client and immediately gets an error that the connection was lost. The server either becomes available for use by another client or terminates (if it is not reusable).
Abrupt Disconnect (client closed without proper shutdown or client system hanged and communication disconnected)	The server does not know that the client has disconnected and remains in the idle state. After timing out based on whichever comes first of the value for the client idle timeout daemon workspace parameter or the TCP/IP KEEPALIVE parameter, the server is notified of the disconnect and either becomes available for use by another client or terminates (if it is not reusable).	The server does not know that the client has disconnected and continues processing. When processing completes, the server tries to reply to the client. After an interval (typically several minutes, depending on the TCP/IP configuration), during which the TCP/IP subsystem retries sending the message to the client, the server assumes that the client is dead and notifies the server that the connection has been closed. The server either becomes available for use by another client or terminates (if it is not reusable).

To troubleshoot client/server communication problems, you need to be familiar with the following:

• The daemon configuration settings

• Oracle Connect for IMS/DB security.

• The TCP/IP subsystem. Oracle Application Server Integration Adapter for IMS/DB uses TPC/IP for internal intermachine communications.

• System details, such as the account name and password of the administrator account, the IP address of the machines involved and whether a portmapper is being used.

Cause: The remote host is not correctly defined to Oracle Connect for IMS/DB or is not working.

Action: Check the remote machine definition in the delivery channel for the adapter.

Action: Check the daemon is up on the OS/390 machine. Use the Status option in the Runtime Manager perspective.

Action: Check the network connection by trying to ping the host machine or run ftp or telnet to or from it.

C045: Failed to create a service thread

Cause: The server failed to create a thread to service a client request.

Action: A system or process quota limit has been exceeded. Either increase the quota or lower the Clients per server limit in the WS Info. section of the daemon configuration.

See Also: "WS Info." for details

C047: %s out of memory

Cause: Not enough memory was available to Oracle Connect for IMS/DB to complete a requested operation.

Action: Kill unnecessary processes running on the server.

Action: Add more memory to the system.

Action: Allow the process to use more memory.

Action: Limit the number of processes the daemon may start. If the demand for servers exceeds the number of available servers, clients get a message telling them the maximum number of servers has been reached and asking them to try again later.

C066: Communication error with the server%s

Cause: Connection to the Oracle Connect for IMS/DB daemon or server failed, or an established session with a server has failed.

Action: Check the remote machine definition in the delivery channel.

Action: Check the daemon is up on the OS/390 machine. Use the Status option in the Runtime Manager perspective.

Action: In case of a network problem, check the network connection by trying to ping the host machine or run ftp or telnet to or from it.

C067: Unexpected error occurred in server function %s

Cause: One of the server functions has exited with an exception (such as an abend, or an Invalid Instruction).

Action: Contact Oracle Support Services.

C068: Fail to login daemon

Cause: The daemon is not running on the server machine.

Action: Use the Status in Oracle Studio Runtime Manager perspective to check whether a daemon is running on the server

Action: Have the system administrator re-install Oracle Connect for IMS/DB on the server.

C069: Fail to get server

Cause: The Oracle Connect for IMS/DB daemon on the server machine could not start a server process to serve the client. A separate message provides more detail on why the server process could not start.

Action: There are many possible causes of this error. If the cause is not clear from the related message, see the Oracle Connect for IMS/DB daemon log file on the server

Action: The resolution to this error is highly dependent on the particular cause. The following are some typical causes and resolutions.

Action: Some process creation quota was exceeded. Either try again later or increase the quota or the other relevant system resources.

Action: The server startup script failed.

Action: The username given is not allowed to use the requested server. Use an authorized username.

Action: A limit on concurrent clients for a server has been reached. Try again later.

Action: If you use impersonation, check the user profile on the client. Also see C015, above.

C06A: Failed to connect to server

Cause: The server assigned to the client did not accept the client connection. A separate message provides more detail about why the server process did not accept the connection.

Action: See the daemon and server log files for the reason that the server was not available to accept its assigned client.

Action: If a multi-threaded server is used and many clients are trying to connect to it at the same time, some may get a Connection Refused error if the TCP/IP request queue fills up.

C06B: Disconnecting from server

Cause: A network failure, or a server machine failure or a server program failure caused the connection to abort. The currently active transaction is aborted as well.

Action: Oracle Connect for IMS/DB automatically tries to re-establish a connection with a server upon the next SQL command issued against the server. Once the network or machine failure is corrected, the connection to the daemon is re-established automatically.

C070: Server failed to send reply to the client

Cause: Server terminated unexpectedly.

Action: Unless the client was intentionally stopped (for example, using Control-C), contact Oracle Support Services.

C071: Connection to server %s was disconnected. Cursors state was lost.

Cause: Either a network failure, a server machine failure or a server program failure caused the connection to abort. The currently active transaction is aborted as well.

Action: Normally, Oracle Connect for IMS/DB automatically tries to create a new session with the server upon the next attempt to access the server. If the network and server are accessible, the next operation should succeed. Otherwise, the network and/or server machine should be fixed before connection can be resumed.

Action: In case of a server crash not related to callable user code, contact Oracle support.

C072: Reconnect to server %s

Cause: This is an informational message only. The client has reestablished its connection with the server.

Action: No action is required.

C073: The parameters passed to the admin server are invalid: %s

Cause: Internal error.

Action: Contact Oracle Support Services.

C074: No authorization to perform the requested operation (%s)

Cause: User/account has insufficient privileges.

Action: Grant administrative privileges to the user/account via the Administrator parameter of the Daemon Security or WS Security sections in the daemon configuration.

See Also: "Daemon Security" or "WS Security" for details

C075: Failed to register daemon in the TCP/IP service table

Cause: Registration of the daemon in the TCP/IP services file has failed.

Action: Check that the account running the daemon has the permissions to update the TCP/IP services file.

E001: Failed in lock/release operation

Cause: A lock or release operation of a global resource has failed. A separate message provides more details. The separate message specifies the cause of this error.

Action: There are various causes for this error, including lack of sufficient privileges or a system resource shortage.
