4 Getting Started with Enterprise Manager

After the Enterprise Manager installation, the Management Service and Grid Control are automatically started. You can immediately log in to Grid Control with the SYSMAN account and begin using Enterprise Manager to manage your enterprise.

This chapter covers Enterprise manager's out-of-box configuration, recommends tasks to perform after installation to begin customizing Enterprise Manager for your particular environment, and contains information on how to configure the Oracle Management Agent and Management Service. The following topics are covered in this chapter:

Enterprise Manager's Out-of-Box Configuration
Using Grid Control for the First Time
Controlling the Management Service and Management Agent

Enterprise Manager's Out-of-Box Configuration

At install time, the following tasks are automatically performed, with no user interaction required:

Default Super Administrator SYSMAN account is created with the password you specified.
The SYSMAN account is automatically configured to receive e-mail notifications if you provided the e-mail notification settings at installation time.
E-mail notifications are set up with default Notification Rules for the critical conditions.
Supported targets located on the same host machine as the Management Agent are automatically discovered.
Targets subtabs are created: Hosts, Databases, Application Servers, Web Applications, Groups, All Targets.

Default Super Administrator: SYSMAN

A default Super Administrator account, SYSMAN, is created with the password you specified during the installation. After installation, you can immediately log in to Grid Control with this user name and password to perform management tasks. The SYSMAN account owns the database schema containing the Management Repository.

To learn more about the SYSMAN user account, refer to the "Setting Up Enterprise Manager for Your Environment" chapter of Oracle Enterprise Manager Concepts.

E-mail Notifications

The SYSMAN account is automatically configured to receive e-mail notifications from Enterprise Manager if, during installation, you specified the Outgoing (SMTP) Mail Server and SYSMAN e-mail address. Also, as part of the self-monitoring feature, a script is created that enables the user to be notified by e-mail in the event that Enterprise Manager goes down unexpectedly.

Note:

If you do not specify the mail server, there will be no notification. If you specify the mail server, but not the e-mail address, the system is set up to send e-mail notifications, but the SYSMAN account will not receive any notifications. If you did not specify the information during install, you can set up e-mail notification afterwards using Enterprise Manager Grid Control.

Notification Rules

E-mail notifications are set up with default Notification Rules for the critical conditions that could occur for all supported target types. For example, for the database target type, a rule is created such that e-mail notifications are sent when any database becomes unavailable, or if any of its key health metrics (Datafile Usage %, Archiver Hung Error Stack, Tablespace Space Used %, and others) becomes critical. The e-mail notifications will be sent to the e-mail address associated with the SYSMAN account. These rules are public; when other administrators are created, they can subscribe to them later.

For more information on the notification rules, in Enterprise Manager, click Preferences, then Rules. Click Help on that page.

Automatic Discovery

The first time the Management Agent is started, the supported targets that are located on the same host machine as the Management Agent are automatically discovered and default monitoring levels and data collections are automatically enabled.

See Also:

For a list of certified targets for Enterprise Manager Grid Control, refer to Table 1-6.

Troubleshooting Problems with Target Discovery

If you are unable to discover targets on a Management Agent host, check for the following problems:

When the Management Agent is installed, an automatic discovery is performed to detect any existing Oracle9iAS 9.0.2 or 9.0.3 instances. If the 9.0.2 or 9.0.3 Oracle9iAS instances were installed by a different OS user than the user that installs the Management Agent, then the file protections on targets.xml within that Oracle9iAS installation may prevent the Management Agent from reading the file. This will prevent the discovery of that Oracle9iAS instance.

To confirm that this is the problem, check the Management Agent logs located at AGENT_HOME/sysman/log/ for "permission denied" errors, where AGENT_HOME is the Oracle home for the Management Agent. To correct the problem, set the file permissions so that it can be read by the user who installed the Management Agent.

This problem does not occur when discovering other existing Oracle Application Server versions on a machine.

If you encounter problems monitoring Oracle Database 10g or ASM targets, refer to "Configuring Database and ASM Targets for Monitoring" in this book.

Targets Subtabs

The Hosts, Databases, Application Servers, Web Applications, Groups, and All Targets target subtabs are created. These subtabs are categories of targets that provide immediate access to the targets you may want to access most often.

See Also:

Refer to the Enterprise Manager online help for detailed information on managing each of these target areas.

Using Grid Control for the First Time

Enterprise Manager Grid Control provides a Web-based interface for managing your entire enterprise. Table 4-1 provides a roadmap of the actions you may want to perform now that Enterprise Manager is installed and running.

The first column describes actions that you may wish to perform; the second contains considerations and reasons for performing the action; the third helps you navigate to the appropriate online help page in Enterprise Manager.

All help topics are contained within the "Setting Up Enterprise Manager" directory of the online help.

Table 4-1 Using Grid Control for the First Time

Action	Purpose	For More Information^Foot 1
Plan Target Management	Consider: Which administrators have access to which targets? How much access does each administrators have to the targets? Which administrators, if any, get system level access? With proper planning, you will have a clearer picture on how to divide the workload among the administrators.	"Setting Up Targets to Monitor and Manage" "Defining Administrators"
Create Additional Notification Methods	If the default e-mail notification is not sufficient. When new administrators are created, they can immediately have access to the methods.	"Setting Up Notifications for Alerts"
Review and Edit Default Notification Rules	If you want SYSMAN to receive notifications for all conditions. If you want a method other than e-mail to be used.	"Managing Notification Methods" in "Setting Up Notifications for Alerts" subdirectory
Create Groups	Logically organize your targets into groups for effective management. You can later grant group access to administrators rather than individual target access.	"Defining Groups"
Create Roles	Create roles to access certain targets and specific management features. Roles are especially useful if there are several administrators that share similar responsibilities.	"Creating, Editing, and Viewing Roles" in "Defining Administrators" subdirectory
Create Administrators	Make sure administrators reflect your management team. Assign administrators roles/privileges to divide their responsibilities. Ensure that no one shares an account. SYSMAN should be the only Super Administrator account.	"Creating, Editing, and Viewing Administrators" in "Defining Administrators" subdirectory
Perform Advanced Configuration Tasks	Enable Secure Mode for Enterprise Manager. Configure firewalls that exist between various components of Enterprise Manager.	For advanced configuration topics, refer to Oracle Enterprise Manager Advanced Configuration.

For information about configuring Enterprise Manager components, such as Management Agents and Beacons, for use in a firewall environment, refer to Oracle Enterprise Manager Advanced Configuration.

Starting the Management Repository Database

If you need to start the Management Repository database, use SQL*Plus to connect to Oracle as SYSDBA, and then issue the STARTUP command.

See Also:

For instructions on managing the repository database, refer to the "Maintaining and Troubleshooting the Management Repository" chapter of Oracle Enterprise Manager Advanced Configuration.

For detailed instructions on starting up a database, refer to the "Starting Up and Shutting Down" chapter in the Oracle Database Administrator's Guide.

Starting and Stopping the Management Service

The relevant emctl commands are listed in the following table.

You must be in the AS_HOME/bin directory to issue the emctl commands, where AS_HOME is the Oracle Application Server home directory in which the Oracle Management Service is installed and deployed.

If you want to ...	Enter the following command
Start the Management Service	emctl start oms
Stop the Management Service	emctl stop oms
Verify status of the Management Service	emctl status oms
Start all components of the Application Server, including the Management Service and WebCache	opmnctl startall
Start all components of the Application Server, including the Management Service and WebCache	opmnctl stopall

See Also:

For more information on using command line utilities, refer to the "Using the Enterprise Command-Line Utility (emctl)" section of Oracle Enterprise Manager Advanced Configuration.

Starting and Stopping the Management Agent

The relevant emctl commands are listed in the following table.

You must be in the AGENT_HOME/bin directory to issue the emctl commands, where AGENT_HOME is the Oracle home directory for your Management Agent. Note that this directory is different than the AS_HOME/bin directory, which is for the Oracle Application Server Control Agent.

If you want to ...	Enter the following command
Start the Management Agent	emctl start agent
Stop the Management Agent	emctl stop agent
Verify status of the Management Agent	emctl status agent

Accessing Enterprise Manager Grid Control

The Oracle Enterprise Manager Grid Control is the primary tool for managing your Oracle environment.

If you need to log in to Enterprise Manager Grid Control, it is accessible through the following URL:

http://<oms_hostname>.<domain>:<port>/em

https://<oms_hostname>.<domain>:<port>/em

If the Management Service is running in non-secure mode, access Grid Control using the Web Cache port. Using the Web Cache port is a prerequisite for self-monitoring. The default port is assigned in the 7777-7877 range.

http://<oms_hostname>.<domain>:7777/em

If the Management Service is running in secure mode, access Grid Control over HTTPS. The default port is assigned in the 4443-4533 range.

https://<oms_hostname>.<domain>:4443/em

If you are uncertain about the port number, you can refer to one of the following files:

ORACLE_HOME/install/setupinfo.txt as displayed by the Oracle Universal Installer at the end of the install
ORACLE_HOME/install/portlist.ini on the Management Service machine

When the login dialog appears, enter the username and password for the Super Administrator SYSMAN.
