Hi,
In Oracle 9i manual, it specifies that we can set retention policies.
Example:
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 5 DAYS;
What does this mean in simple terms? Does this mean we need a backup that is no older than 5 days from the current date? Therefor, should we perform a backup everyday and delete backups older than 5 days?
Thanks ... IA

Hi,
It means that RMAN will mark files NOT REQUIRED for a restore (files what will be used if you need to restore the DB to a point in time longer than 5 days ago) and mark them as obsolete. Obsolete files will remain in the catalog, however, you can purge them using the DELETE OBSOLETE command.
Best regards.
Frank
