Which two are true about the use of RMAN recovery catalogs when offloading backups to a physical standby database? (Choose two.)
A. It backups that are offloaded to a physical standby database are taken when not connected to a recovery catalog, then they may still be used for restoration on the primary database.
B. The physical standby database may be used to register the database in the recovery catalog, if the primary is not registered.
C. The primary and physical standby databases must be registered separately in the recovery catalog, if a far sync instance is used to route redo to the physical standby database.
D. It is not necessary to use a recovery catalog unless a far sync instance is used to route redo to the physical standby database.
E. Primary and physical standby database may use different virtual recovery catalogs in the same physical recovery catalog.
Correct Answer: DE
Explanation/Reference:
E: The RMAN recovery catalog is subdivided into multiple virtual recovery catalogs.
D: The following RMAN configurations are recommended at a standby database where backups are not done:
1. Connect RMAN to the standby database as target, and to the recovery catalog.
2. Enable automatic deletion of archived logs once they are applied at the standby database (this is also applicable to all terminal databases when the cascading or far sync instance features are in use)
Incorrect Answers:
A: When using RMAN in an Oracle Data Guard environment, you should always connect it to a recovery catalog. B: You should not explicitly register the standby database in the recovery catalog.
