That's why I said 4 at most.

So that's why I arrive to have it 5 groups. But that's me. :-))
You will be fine with 4 :-))
sure Julian, 4 will be fine, I usually make it 5 when there are other processes running in the server aside from Oracle process which sometimes cause redo logs to get STALE status if that process also has an I/O operation.

so we're cool now :-))
