You are administering a multitenant container database (CDB) cdb1 that is running in
archivelog mode and contains pluggable databases (PDBs), pdb_i and pdb_2. While
opening pdb_1, you get an error: Exhibit: To repair the failure, you open an RMAN session
for the target database CDBSROOT. You execute the following as the first command:
RMAN>REPAIRFAILURE; Which statement describes the consequence of the command?
A.
The command performs the recovery and closes the failure.
B.
The command produces an error because RMAN is not connected to the target database
pdb_1.
C.
The command produces an error because the advise failure command was not executed
before the REPAIRFAILUER command.
D.
The command executes successfully, performs recovery, and opens PDB_1.
C
D.
Repairs failures recorded in the Automated Diagnostic Repository.
If you execute REPAIR FAILURE with no other command options, then RMAN uses the first repair option of the most recent ADVISE FAILURE command in the current session. The command performs an implicit ADVISE FAILURE if this command has not yet been executed in the current session.
