Chapter Reference
The
create script
command is referenced in Chapter 10.
Example
create script backup db {backup database plus archivelog delete input;}
crosscheck Command
The
crosscheck
command is used to verify that existing backup sets and backup set pieces listed in the control file or recovery catalog exist on the backup media. Any physical backup file (backup set piece, copy, and so forth) that is not found on backup media is marked as EXPIRED
and will not be considered by RMAN for recovery operations. If the backup file later appears, then it will be marked AVAILABLE during a subsequent
crosscheck
operation.

delete Command
The
delete
command allows you to mark backups and copies in the recovery catalog or control file with a status of DELETED. Once backups or copies are marked DELETED, the status cannot be changed. Objects that are marked as EXPIRED (via the
crosscheck
command) or OBSOLETE (via predefined retention criteria) can be marked DELETED with the
delete
command.
