Oracle 11g New Feature: RMAN Data Recovery Advisor
In Oracle 11g, RMAN provides a new advisor called Data Recovery Advisor (DRA). DRA has several new commands to help DBAs for performing recovery tasks.
To list of database failures, you can issue:
|
1 2 3 4 5 6 7 8 9 |
RMAN> list failure; List of Database Failures ========================= Failure ID Priority Status Time Detected Summary ---------- -------- --------- ------------- ------- 522 HIGH OPEN 08-SEP-09 One or more non-system datafiles are missing |
DRA will consolidate related failures into a single failure. You can list a failure individually by issuing “list failure X detail” command.
