Using EMCA with Real Application Clusters

In this section, I will be using two Database Control consoles running; one on linux1 and the other on linux2. From either of these consoles, you can manage and monitor all targets in the cluster.

* For information on the current cluster configuration, you can run:

$ emca -displayConfig dbcontrol -cluster

The above command prompts for the database unique name for the cluster database. This will print the current configuration onto the screen, indicating the nodes that have consoles running on them and the consoles where each agent is uploading.

* Create Database Console

$ emca -config dbcontrol db -repos create -cluster
