no reason. I can see creating multiple files under those conditions only because you want to keep files to a specific size.

Now, I did once find that the rollback datafiles were a bottleneck on a system I had. So we built TWO rollback tablespaces, with datafiles on different mount points etc and the rollback segments divided between the two tablespaces.

cleared up that bottleneck like a dream

other than that though.. why?
