RE: Oracle software on RAID 5

We have some Oracle 8.0.5 DBs on a RAID5 set on our OpenVMS server. It works fine, but there is really not a lot of writes going to our DBs
(read-only "legacy" data). You don't mention the type of database
(OLTP/DW/Hybrid) or it's size, number of concurrent users, etc., so I'll be
generic. Writes *will* be slowwwwww. Creating new datafiles will bring DB writes to a halt. Mildly heavy transactions will cause the DBWRs to go nuts. You will probably have the most problems with your online redo logs. We've been able to compensate somewhat by increasing the size of our redo log buffer. But then again, we're not heavy on the transactions.

Good luck!

We are in the process of reorganizing and reconfiguring of our disk space in preparation for an Oracle 8.1.6 upgrade in production, and my sys admin wants to use RAID 5 for the drive on which the Oracle 8.1.6 software will be installed. Anyone know of a reason why RAID 5 would not be OK for the software? We are on Digital Tru64 UNIX V4.0G.

Thanks in advance,
