Home -> Community -> Usenet -> c.d.o.tools -> Re: How do you configure 2 Oracle DBs on 12 RAID disks?
I've been researching a similar problem recently with Oracle7 databases on OpenVMS, so this might help a little. According to an article from Oracle Support on Metalink (use the keyword striping if searching there) Oracle recommends RAID 0+1 (striping+shadowing) for datafiles, and RAID 1 for control files, archive logs, and redo logs. RAID 1 should be the max used for redo logs and archive logs in any case. If you can't use RAID 0+1 for datafiles, they recommend RAID 1 or RAID 5. I wish I could remember to article off-hand, but if you search MetaLink with the keyword above, you should find several RAID articles.
Hope this helps.
