I am using Oracle 10.2.0.3 Enterprise Edition on RHEL.
I am configuring Data Guard for a RAC two node database. I am trying to learn configuring Data Guard Broker for a RAC database.
The database is a RAC database (orcl) with instances orcl1 and orcl2 configured on nodes rac1 and rac2.
Now I have created a physical standby database with db unique name orcl3 on node rac2 and the db name is orcl as needed for a standby. This is not a RAC database.
I am trying to configure data guard broker for the same. I am running the following commands from rac2 node with the environment pointing to the database orcl3.
