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, centrallymanaged, RMAN
recovery catalog. This goal can be achieved by implementing virtual private catalogs.
