Which two activities are NOT supported by the Data Recovery Advisor (DRA)? (Choose
two.)
A.
Recover from failures in the RAC environment.
B.
Diagnose and repair failures on a standby database.
C.
Diagnose and repair a data file corruption online.
D.
Diagnose and repair a data file corruption offline.
A AND D
It’s A and B:
“The DRA (in the current release) only supports single-instance databases. If a
fault brings down a RAC database, you can mount it in single-instance mode, use
the DRA to repair the damage, and then shut it down and reopen it in RAC mode.
This technique may not be able to repair damage that is local to one instance. The
DRA cannot repair failures on a primary database by using blocks or files from a
standby database, and neither can it repair failures on a standby database.”
