Guidelines for Oracle RecoveryFor optimal Oracle recovery, follow these guidelines:
![]() A control file is a small binary file that describes the structure of the database and must be available to mount, open, and maintain the database. The control file stores all necessary database file information, log file information, the name of the database, the timestamp of database creation, and synchronization information, such as the Storage Checkpoint and log-sequence information needed for recovery. Rolling back the control file will result in an inconsistency between the physical database structure and the control file. ![]() A database backup with online and archived logs is required for a complete database recovery. Query V$ARCHIVED_LOG to list all the archived log information and V$ARCHIVE_DEST to list the location of archive destinations. To restore the necessary archived redo log files, you can query V$LOG_HISTORY to list all the archived redo log history or query V$RECOVERY_LOG to list only the archived redo logs needed for recovery. The required archived redo log files can be restored to the destination specified in the LOG_ARCHIVE_DEST parameter or to an alternate location. If the archived redo logs were restored to an alternate location, use the ALTER DATABASE RECOVER ... FROM statement during media recovery. ![]()
SET AUTORECOVERY ON; RECOVER DATABASE;
RESETLOGS resets the log sequence. The RESETLOGS option is required after an incomplete media recovery. After opening the database with the RESETLOGS option, remove the Storage Checkpoint you just rolled back to as well as any Storage Checkpoints that were taken before that one. These earlier Storage Checkpoints can no longer be used for Storage Rollback. After removing these Storage Checkpoints, be sure to create a new Storage Checkpoint. ![]() See your Oracle documentation for complete information on recovery. |
