How to enable your 11g RAC to be active/passive

Starting with 11g, the INSTANCE_COUNT parameter is no longer valid. You will have to manually add a service name to the cluster and connect to it.
Example:
srvctl add service -d PS -s PS_SVC -r PS1 -a PS2,PS3,PS4…
-d <db name>
-s <service name>
-r <primary instance>
-a  <alternate instances>

After running this command, the default is for this service to start up when the DB starts. The service name will automatically be configured to the listener.

Check by running, “lsnrctl status” and you should see the new service name included in the output.
