Discovering Oracle RAC database and instance targets in Oracle Enterprise Manager enables monitoring and administration.
Oracle Enterprise Manager Cloud Control enables you to use the Oracle Enterprise Manager console interface to discover Oracle RAC database and instance targets.
If the Oracle Enterprise Manager Cloud Control agents are installed on a cluster that has an Oracle RAC database, then Oracle RAC database targets are discovered at install time. You can use the console interface to discover targets if a database is created after agents are installed or if a database is not automatically discovered at agent install time.
To discover nodes and instances, use Oracle Enterprise Manager Cloud Control as follows:
Log in to Oracle Enterprise Manager and click the Targets tab.
Click the Database tab to view all of the available targets. The column labeled Types shows the Oracle RAC databases using the entry Cluster Database.
Add the database target by selecting the target name, then clicking Add. The Add Database Target: Specify Host page appears, which enables you to add databases, listeners, and Oracle ASM as monitored targets.
Click the flashlight icon to display the available host names, select a host, then click Continue. The Add Database: Specify Source page appears.
Either request Oracle Enterprise Manager to discover only noncluster databases and listeners, or to discover all cluster databases, noncluster databases, and listeners on the cluster, then click Continue.
If this procedure did not discover your reconfigured cluster database and all of its instances, you can use the Targets Discovered on Cluster page to manually configure your cluster database and noncluster databases.
