15.You are in the process of creating a virtual private catalog in your Oracle Database 11g database. The

PROD1, PROD2, and PROD3 Oracle Database 10g databases are registered in the base recovery
catalog. The database user who owns the base recovery catalog is CATOWNER. CATOWNER executes
the following command to grant privileges to a new user VPC1 using Oracle Database 11g RMAN
executables:
RMAN> GRANT CATALOG FOR DATABASE prod1, prod2 TO vpc1;
Then you issue the following commands:
RMAN> CONNECT CATALOG vpc1/oracle@catdb;
RMAN> SQL "EXEC catowner.dbms_rcvcat.create_virtual_catalog;"
What is the outcome of the above commands?
A. They execute and create a virtual catalog for pre-Oracle 11g clients.
B. They produce an error because PROD1 and PROD2 databases belong to the older version.
C. They produce an error because you need to connect as CATOWNER to execute this packaged
procedure.
D. They produce an error because you need to connect to the target database to execute this packaged
procedure.
Answer: A

You must take an extra step when intending to use a 10.2 or earlier release of RMAN with a virtual catalog. Before using the virtual private catalog, this user must connect to the recovery catalog database as the virtual catalog owner and execute the following PL/SQL procedure (where base_catalog_owner is the database user who owns the base recovery catalog):
base_catalog_owner.DBMS_RCVCAT.CREATE_VIRTUAL_CATALOG
