If it were a data or an index tablespace, laying out a tablespace across
multiple datafiles could help in striping data or partitioning. And as
Kirti said, could be to balance the I/O across multiple disks.

Other than I/O load balancing.. I can't see any other reason.

But again, why those tiny 50MB files?
Are these on the same disk? I hope not..

If there is no I/O bottleneck issues,  I would build just one 700MB file.
And then monitor how it works out..

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.
