As one of the other posters said, Oracle doesn't care about whether you
use OS level striping or not. However, YOU DO. We are running our stripes
against 4 physical disks (1Gig per) to get our mount points, and mirroring
them as well. The increase in throughput is quite noticeable. OTOH, you
must be very sure to deploy your tablespaces in such a manner as to
prevent overlap and IO contention, just as with single physical disks;
this will prevent nullifying the advantages of the stripe. We store redo
logs, data and index tablespaces on stripes; control files, scripts, and
less used tablespaces (USERS, TOOLS) on simple volumes (also mirrored).
Temp space tablespace MUST be on a stripe if you plan to do any sorting
(who wouldn't?).
BTW, I love the Solaris 2.4/Oracle 7.1.4 combo! Let me know if I can help with any more info.
