RMAN Backups of a Standby, and db_unique_name
This is RAC version 10.2.0.4 I've created a physical standby on node 1 of the standby cluster, and the standby is being properly updated by the primary. However, I did not give the standby a db_unique_name; it's the same as the primary. The primary is registered with an RMAN catalog.
I've been able to take RMAN backups from the standby node; I connect to the same catalog where the primary is registered, and the DBID here = primary DBID.
Will I be able to use these backups (made at the standby) to perform any needed restore/recovery on the primary? Every document calls for a distinct db_unique_name for the standby "in a Data Guard environment." I do not need Data Guard to manage my standby database, and will not run a DG broker. If an activation of a standby is needed, this is done manually. I have tested manual activation of the standby and it works as expected.
