Re: Hot backup - when to clear those archived logfiles? Must reset logs?

        Incorrect, if you like to live dangerously and delete all of the old archives you want to do a switch log just before you start the hot backup. Remember that the redo logs created during the backup will have to be applied if you need to recover. Therefore you shouldn't delete the redo logs and archives created while running the hot backup.

        Why do you want to cut things so close? It requires you to micromanage your backups and be there to determine what to keep and what to delete. Assuming you are running nightly backups you are better off writing a script that runs the backup and then deletes any archives that are more than one day old.
