Oracle Dataguard Broker Agent.
Just wanting some more information surrounding the Oracle Dataguard Broker Agent for Oracle RAC. I'm reading page 16/17/18 of the VCS agent for Oracle Dataguard Installation and configuration guide.
We've 2 SFRAC clusters comprising 2 servers each. On both, the database stays up all the time with dataguard replicating from one side to the other. But how do i setup dataguard agent broker to monitor replication between the two and how does it handle failover? If both databases are up all the time how does the dataguard agent decide which one is the active and which is the standby? I've put it in a global service group so assume its achieved via that?
At the moment I've got two parrellel service groups on each cluster - the first is a local service group which has the diskgroups, mounts and oracle database reources. The second has the Dataguard agent broker and is a parrellel global service group which is its parent.
