Re: 9i-OCP Question

There are two reasons:
1) Redo log groups are never used simultaneously, so they can reside on

    the same disk. Log members should not be on the same disks for increased     survivability. That gives us 2 groups with 4 members, each two members     sharing the same device - 4 disks alltogether. 2) It's because I say so and I'm an 8i OCP.
