Home -> Community -> Mailing Lists -> Oracle-L -> RE: # of datafiles per tablespace
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.
