RE: 4 disks......

I'm with Sean... You can not really get an optimum config with 4 disks... But given that you have 4, protect the redo's the best you can. Also-do you have an internal disk for the OS?? IF you need to share a disk with all of the OS-place the oracle software, scripts, etc with the OS disk..

We recommend 10 disks, PLUS MIRRORS, for a typical Oracle install. And that's just for a standard setup for an Oracle infrastructure-nothing large...

Don't forget:

1 disk for rollback segments
1 disk for system ts
1 disk for temp ts

Also, exports would probably be better put on the Oracle software disk. If you only have 4 disks, you should rearrange things a bit...

disk a - oracle software, exports, redo
disk b - rollback, index
disk c - system, temp
disk d - redo, data

There's really no good configuration for just 4 disks. You REALLY DO NEED TO MIRROR REDO-LOGS... HTH,
Sean
