RC_ views and RMAN related V$ views
DB version : 10.2.0.5
I have 2 questions on catalog based RC_views and Control file based RMAN related V$ views
Question1.
An RC View (for eg:RC_BACKUP_PIECE) can be queried only after connecting to the catalog schema. Right ?
Question2.
We use recovery catalog schema to store our Backup info. ie. we connect to recovery catalog schema before taking any backups.
But I can see that our control file based V$BACKUP_PIECE view has the most up-to-date info on backup pieces. How does the control file know about this ?
