System Monitoring Plug-in for Oracle TimesTen In-Memory Database Installation Guide
Release 11.2.1
E13081-03
September 2009
The Oracle TimesTen In-Memory Database Plug-in extends Oracle Enterprise Manager Grid Control to add support for monitoring TimesTen databases.The installation guide contains information to review before installing the Oracle TimesTen In-Memory Database Plug-in:
The installation guide also contains the procedures necessary to install the plug-in, view data about your target instance (your database), and to uninstall the plug-in:
You can also find information about the location of Oracle TimesTen In-Memory Database documentation.
The Oracle TimesTen In-Memory Database Plug-in supports Oracle TimesTen In-Memory Database Release 7.0.3 and later 7.0 releases.The plug-in also supports Oracle Enterprise Manager Agent:
Release 10.2.0.4
Release 10.2.0.3
Release 10.2.0.2
Release 10.2.0.1
Note:
Oracle Enterprise Manager Agent Release 10.2.0.4 is recommended. The plug-in does not support Oracle Enterprise Manager DBControl.Before installing the Oracle TimesTen In-Memory Database Plug-in:
Install Oracle Enterprise Manager Agent Release 10.2.0.1 or later. Make sure the agent can successfully communicate with your Oracle Enterprise Manager Server and can upload data. For example, Agent Availability
must be UP
, Last Load Time
should show a recent date/timestamp, and Last Load Time
should get periodically updated.
Install Oracle TimesTen In-Memory Database Release 7.0.3 or later.
Note:
The Oracle Enterprise Manager Agent must reside on the same machine as the Oracle TimesTen In-Memory Database.When you install the Oracle TimesTen In-Memory Database Plug-in, you need to know:
The name of your TimesTen instance
The DSN
If you have enabled Access Control on your TimesTen instance:
The TimesTen username
The password for the TimesTen username
Note:
Be sure the TimesTen database specified by the instance and DSN is loaded.For information on your TimesTen instance, run the ttStatus
utility.
You need to set credentials in Oracle Enterprise Manager for the user that the agent runs as. You can either set default credentials (credentials are the same for all agents) or you can set different credentials for each agent (target credentials). Target credentials override default credentials.
Choose Preferences located in the top right of the Oracle Enterprise Manager home page.
Choose Preferred Credentials located in the top left of Preferences.
Click the icon in the Set Credentials column in the row for the agent.
You see the Agent Preferred Credentials page. You are ready to enter default and target credentials by entering the operating system username and password for the agent.
In the Host UserName column, type the username.
In the Host Password column, type the password.
Click Apply.
You need to set credentials for agents by setting the host username and host password in Oracle Enterprise Manager Grid Control. On Windows, you need to grant to the host username the Logon as a batch job
privilege.
For more information on setting credentials, see "Setting credentials in Oracle Enterprise Manager".
Set your control panel to classic view
.
From the desktop, choose Start > Control Panel > Administrative Tools.
Double click Local Security Policy.
Choose Local Policies.
Choose User Rights Assignment.
Double click log on as a batch job.
The log on as a batch job Properties dialog appears.
Click Add User or Group.
The Select Users or Group dialog appears. You are ready to enter the host username.
In Enter the Object Names to Select, type the host username.
Click OK.
Click OK on log on as a batch job Properties dialog.
