Explanation:
About Virtual Private Catalogs
By default, all of the users of an RMAN recovery catalog have full privileges to insert, update, and delete any
metadata in the catalog. For example, if the administrators of two unrelated databases share the same
recovery catalog, each administrator could, whether inadvertently or maliciously, destroy catalog data for the
other’s database. In many enterprises, this situation is tolerated because the same people manage many
different databases and also manage the recovery catalog. But in other enterprises where clear separation of
duty exists between administrators of various databases, and between the DBA and the administrator of the
recovery catalog, you may desire to restrict each database administrator to modify only backup metadata
belonging to those databases that they are responsible for, while still keeping the benefits of a single, centrally
managed, RMAN recovery catalog. This goal can be achieved by implementing virtual private catalogs.
