Database Error Messages

ORA-45159

RECOVERY_WINDOW_GOAL is lost for database string.

Cause

Backups needed to support the recovery window goal for the named database did not exist. The backups were either explicitly deleted by a user or were implicitly reclaimed due to a space shortage in the storage location for the database. There may also be archived logs missing to accomplish the desired recovery window goal.


Action

This is a warning and no action is needed. However, use the DBMS_RA.UPDATE_PROTECTION_POLICY to increase the DISK_RESERVED_SPACE value of the database to ensure that additional backups are saved. Select SPACE_USAGE from the RA_DATABASE view to see how much space is currently in use. Also, check for KEEP backups consuming space on disk and decide if they should be moved to tape or other disk storage. See the DBMS_RA.MOVE_BACKUP_PIECE for more details.
