Archived logs are not necessarily useless after a cold backup. When in
archive log mode you can roll forward using a cold backup as the base.
Archived logs made before the last cold backup could be necessary if the
prior hot or cold backup had to be applied and rolled forward either due to
some type of logical corruption or the loss of one or more of the most
recent cold backup files occurred and a media recovery operation became
necessary.

After a good cold backup, your old archived logs are useless. It would be
better to store the files from cold back up, rather than old archived logs
on DVD. Becuase if the system dies, you still have a good cold back up,
rather than the useless old archived logs.

Hi All,
Previous DBA did not set up any archived logs maintanance here si I am in
the process of developing a process that will store old archived logs on
DVD. We're on 9.2.0.5 on Win2K. Here is what I am thinking: after each cold
backup, do alter system archive log current to archive the latest redo, zip
all old logs and copy them to DVD, then delete them from disk. Can someone
share a script or info on this?
Thanks
