It is a holiday and no transactions are being performed on the database. You took a consistent backup of your database without using Recovery Manager (RMAN).
How would you make use of this consistent backup in RMAN?
A. cannot be used in RMAN
B. by starting up the database again
C. by using the CATALOG command of RMAN
D. by using the RECOVER CATALOG command in RMAN
E. by re-creating the target control file to rebuild the RMAN repository
Answer: C
Purpose
Use the CATALOG command to do the following:
-
Add backup pieces and image copies on disk to the RMAN repository
-
Record a data file copy as a level 0 incremental backup in the RMAN repository, which enables you to use it as part of an incremental backup strategy
