In the context of high availability databses, my configuration is as follow:
2 AIX servers on 2 sites with shared storage -> Site1 and site2.
During normal operations databases are on site1. In case of disaster, databases can fallover on site2.
On my Grid Control, 2 agents are installed: One for AIX on site1 and one for AIX on site2.
Databases have been discovered on AIX:site1
Listener is a virtual address and can also fallover.
What are the possibility on the grid side ?
Do I have to discover also the databases on site2 ?
Actually, Listener is seen down on the site who has not the databases.
Is there a way to only configure the Listener virtual address on the Grid ?
Basically you have to relocate the targets to the new agent (the one installed on site2). I haven't done that, but I expect to work fairly easy and smooth. Refer to the following section of Cloud Control 12c manual:
Configuring Targets for Failover in Active/Passive Environments
