| |RMAN [Oracle] |
|[pic][pic][pic][pic] | |RMAN is a program that helps to manage backing up, restoring and|
| | |recovering databases, or more accurately their datafiles. |
| | |Features|
| | |While backing up, restoring and recovering are possible with |
| | |user managed backup recovery, RMAN also has some additional |
| | |features:|
| | |Incremental backup |
| | |Block media recover |
| | |Unused blockcompression |

| | |Terminology |
| | |Target database |
| | |In RMAN's terminology, the database onwhich it is operated |
| | |(that is backed up, restored or recovered) is called the target |
| | |database. One recovery catalog can manage multiple target |
| | |databases.|
| | |Channel |
| | |A channel is a connection (session) from RMAN to a target |
| | |database. These connections, or channels, are used toactually |
| | |perform the desired operations. |
| | |Physical standby databases |
| | |RMAN can use physical standby databases to make backups. This|
| | |saves valuable resources on the primary database. |
