It only requires you to copy the archived redo logs. This is assuming that you delete the logs that have been backed up via RMAN and you are only copying redo logs that have not yet been backed up. You have to do this because the duplicate will bring the auxiliary database up to the last full backup. Then the redo logs are incrementally applied. Received on Wed Jul 27 2005 - 12:19:33 CDT
