Which CLAUSE is used in the DUPLICATE DATABASE command to let RMAN know that you aren’t using prior backups of the target database as source but are instead using the network for the database duplication?
-
from target database
-
from live database
-
from source database
-
from active database
D
Correct answer
Explanation
The DUPLICATE DATABASE command with FROM ACTIVE DATABASE clause tells RMAN to duplicate the target database over the network instead of using pre-existing backups. This is used for active database duplication where RMAN connects to the target database and copies data files directly. The other options (from target database, from live database, from source database) are not valid RMAN clause syntax for this purpose.
