Starting with 10g, it's possible to use the rman CATALOG command to add backuppieces stored in disk to the rman repository.
You may need to catalog backup pieces in the following situations:
You copy or move a backup piece with an operating system utility and want it to be usable by RMAN.
The RMAN metadata for the backup piece was removed, but the backup piece still exists. This situation can occur if you ran the
DELETEcommand on a backup piece that was only temporarily unavailable.
You make a
NOCATALOGbackup on one database host in a Data Guard environment and move the backup piece to the same location on a different database host. In this case, the recovery catalog has no record of the original backup piece.
You do not use a recovery catalog and must re-create the control file, thereby losing all RMAN repository data. Cataloging your backups makes them available again.
When control file autobackup is disabled, you back up the control file and then back up the archived redo logs. You can restore and mount the control file, but must catalog the backup pieces containing the archived redo logs backed up after the control file.
But it's not possible to use the CATALOG command for backup pieces stored in TAPE. This note explains how to add backuppieces stored in TAPE to the repository
