Stripping??? I hope you meant "striping", otherwise this discussion could be taking a VERY unusual turn!

Kevin, let me introduce you to the world of stripping. Course, if you are on old hardware that really isn't like it is today.

I am sure its been said in the notes I have not read yet .... but, my biggest reason for having the multiple files is to have multiple drives. Each file on a different drive means that the access to the file can be spread out. Therefore you can have multiple processes accessing the files at the same time with reduced io contention.

OK, I know we had the debate already but lets have another go at it.

Say you got a tablespace, lets call it RBS and its for rollbacks. Now, for what reason would you create a 500M file and 4 50M files for this puppy as opposed to just one file. I just cannot see the reasoning for this at all. None. Natta. Zilch.

So educate me please if someone out there knows a legit reason they would do this.

Lets assume for the sake of argument that disk size and mount point size is not a limitation. Space available to me on any one mount point is unlimited.
