ORACLE datafiles on mirrored disks

Hi there!

I would like to know if there is anybody out there running ORACLE V7.x on mirrored disks. The management people here are concerned about high availability and decided to put all data on mirrored disks. As we are using a lot of app's that work in a classical fileserver architecture (LanManager/X) this is understandable. Backup is done by 'unmounting' the mirrored disk, copying to tape and 'mounting' it again.

The questions are:
- How does this procedure comply with ORACLE data files?

• What should be done before/after backup? Same SQL*DBA-commands like with 'normal' online-backup ('alter tablespace begin backup' ...)?
• Is it safe to put the (online- and offline-) redologs on the same volume as the data files?

Any comments/suggestions are welcome!

Thanks in advance
