Yong,
One of the purpose of a cold backup is to have a complete copy of the database that can be restored somewhere else & immediately started. In that case you need ALL of the database files, temp, rollback, and online redo logs as well as the working tablespaces. One other point to consider is that during a shutdown where the current redo log is not full it is not copied to the archive location as part of the shutdown. Instead the DB will restart where it left off in that log.
I know Oracle recommends otherwise, but in all of our backups I recommend backing up everything. It burns more tape, but it also has saved my bacon in the past. Therefore, if in doubt, back it up.

Hi, Christian,
Why do you have to back up redo logfiles when you do cold backup? Are you saying there could be some remaining redo records left in redo logs, even with a normal shutdown?

No if it is a cold backup. However and in terms of recovery, if you don't backup the redo logs, you'll need it.
Oracle recommends not to backup redo logs, but in the case of cold backups you should do it because of the absence of archives.
