4. Backup and Recovery Protects From Data Loss Provides for Media Recovery Backup Types Physical Logical Types of Backups Recovery Manager (RMAN) User-Managed (including third party utility)

5. Backup Strategy Comprehensive RMAN Database files, including datafiles, control files, and the server parameter file ( SPFILE ) Archived redo logs OS Network configuration files ( listener.ora, tnsnames.ora, et cetera) Password files External tables Oracle home

6. RMAN BACKUP Command Basic BACKUP Commands: BACKUP DATABASE BACKUP CURRENT CONTROLFILE BACKUP SPFILE BACKUP ARCHIVELOG ALL

7. RMAN Default Configuration Backup Location OS Dependent Backup Type Disk Backup Channels One MAXSETSIZE Unlimited

RMAN> connect target tsb@mylrep target database Password: connected to target database: MYLREP (DBID=518368273) RMAN> backup database; Starting backup at 12-JUN-08.Output from backup is printed here. Finished backup at 12-JUN-08 RMAN> exit

9. BACKUPSET vs. COPIES BACKUP SET Consists of BACKUP PIECES Proprietary Format Backup "USED" blocks Only RMAN can be used to restore/recover

10. BACKUPSET vs. COPIES BACKUP SET Consists of BACKUP PIECES Proprietary Format Backup "USED" blocks Only RMAN can be used to restore/recover COPIES Identical to OS copies. Can be used as replacement to datafile. Can be used in user-controlled recover/restores.

11. Block Change Tracking Used for Incremental Backups Traditional incremental backup read entire datafile. Enabled Block Change Tracking Creates Change Tracking File ( CTF ) Use CTF to determine blocks to backup Consider Environment

12. Enabling and Disabling Change Tracking Current State: SQL> SELECT * FROM V$BLOCK_CHANGE_TRACKING; Enabling/Disabling: SQL> ALTER DATABASE ENABLE BLOCK CHANGE TRACKING; SQL> ALTER DATABASE ENABLE BLOCK CHANGE TRACKING USING FILE '/oracle/bu/rman_change_track.f' REUSE; SQL> ALTER DATABASE DISABLE BLOCK CHANGE TRACKING;
