The following steps are useful to delete the backups which are marked as NO-EXPIRE. No expire backup are the backups for which the retention policy will not apply and the backups remain till you manually and forcibly delete these backups. The best example for No-expire backups are the backups kept for training purposes. After successfully creating any training environment, we will backup the database with NO-Expire option and these backups will be used to refresh the database every week.
The following commands show you how to delete these no-expire backups on tape from RMAN CATALOG. This is useful in cases where if you made any changes to the databases and need to preseve these changes in the database forever, you will take new NO-EXPIRE backups and delete the old backups.
Hope it helps
