Thanks, for the example script. I had already reached the conclusion that "change backuppiece ..." was needed, but hadn't yet figured how to query for the proper pieces.

Ian,

I think retention policy is new in 9i.

I purge my repository of backups that are older than 90 days (because our tape systems rotates and reuses tapes after that time) using the "change backuppiece 330783 delete; " command. I run a sql script againts the rman repository looking for pieces that satisfy this requirement. The sql looks like this:

select 'change backuppiece bp.bp_key delete;' from rc_backup_piece bp,rc_database db
where db.name = upper('ORACLE_SID')
and bp.db_id = db.dbid
and bp.start_time < sysdate-90
/

This is in an 8i database.

Hope this is what you were looking for.

How is this set on 8.1.7 and 8.1.6 databases

RMAN> CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 8 DAYS;

RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-00558: error encountered while parsing input commands
RMAN-01005: syntax error: found "identifier": expecting one of: "compatible"

RMAN-01008: the bad identifier was: RETENTION RMAN-01007: at line 1 column 11 file: standard input

I looked at commands such as

crosscheck backup of database completed before 'SYSDATE-7'; delete expired backup of database completed before 'SYSDATE-7';

But crosscheck only expires backups which are in the catalog, but not available on the backup media.

Do I have to use the change command and designate each backup piece?
