Keywords and Parameters

Syntax Element	Description
ORPHAN	Specifies as obsolete those backups and copies that are unusable because they belong to incarnations of the database that are not direct ancestors of the current incarnation. Note that RMAN displays orphaned backups in addition to the normal display of obsolete backups. See Also: Oracle Database Backup and Recovery Advanced User's Guide for an explanation of orphaned backups
RECOVERY WINDOW OF integer DAYS	Specifies that RMAN should report as obsolete those backups and copies that are not needed to recover the database to any point within the last integer days. See Also: "CONFIGURE" for an explanation of the recovery window
REDUNDANCY = integer	Specifies the minimum level of redundancy considered necessary for a backup or copy to be obsolete. A datafile copy is obsolete if there are at least integer more recent backups or image copies of this file; a datafile backup set is obsolete if there are at least integer more recent backups or image copies of each file contained in the backup set. For example, REDUNDANCY 2 means that there must be at least two more recent backups or copies of a datafile for any other backup or copy to be obsolete.

Example

Deleting Obsolete Backups: Example

The following command deletes all backups and copies not needed to recover the database to a random point within the last 30 days:

DELETE OBSOLETE RECOVERY WINDOW OF 30 DAYS;
