The CATDB12c database contains an Oracle Database version 12c catalog schema owned by the RC12C user.
The RCAT11 database contains an Oracle Database version 11g catalog schema owned by the RC11 user in which several databases are registered. Both the databases are open.
You execute the RMAN commands:
RMAN> CONNECT CATALOG rc12c/pass12c@catdb12c
RMAN> IMPORT CATALOG rc11/pwdcat11@ract11
Which two tasks are performed as part of the import?
A.
All databases registered in the RC11 catalog are registered in the RC12C catalog.
B.
Databases from the RC12C catalog are implicitly unregistered if the RC11 catalog has registered databases with same name.
C.
Local and global stored scripts that have the same name as existing scripts in the RC12C catalog are automatically renamed.
D.
Imported databases are unregistered from the RC11 catalog.
E.
Recovery catalog is resynchronized with the control files of the registered databases.
AD
RMAN must be connected to the destination recovery catalog, which is the catalog into which you want to import catalog data.
The unregister operation is separate from the import. By default, the imported database IDs are unregistered from the source recovery catalog schema after a successful import.

Ensure that the same database is not registered in both the source recovery catalog schema and destination catalog schema. If a database is registered in both schemas, then UNREGISTER this database from source recovery catalog and execute the IMPORT command again.
