Jeffery,
 That brings up the age old contriversy if seperating ifo on different spindles.
there are many reasons one might like to separate data and indexes, ease of backing up your data by type on different tapes, the ability of a database to function incase of an index disk failure, OFA,
Ease in managing disk growth

ON the other hand..
If the data and index are on one disk the supposidly the info retrievel is faster
because the disk head is already in motion, It takes less disks if the data and index are combined. Etc.
The answer is "it all depends..."

We have started using locally managed tablespaces for all new tablespaces. We create the tablespaces with autoallocate.  

Since the tablespaces are locally managed, is there a need to separate the tables and indexes anymore?
