Home -> Community -> Mailing Lists -> Oracle-L -> RE: Separate tablespaces for indexes on same table?
Hi Cherie,
Whatever happened to the thought over there that I/O contention just didn't happen on a Symmetrix? (I never believed it)
Personally I'd opt for two tablespaces on truly separate disks, though this is difficult to determine on the symmetrix. Just my bias.

I am rebuilding some indexes for a 20-Gig table. I am following the recommendations in the paper How to Stop Defragmenting and Start Living...
There are six indexes on this table. According to the paper, I should create a separate tablespace for these indexes. My question is: Should I put all of the indexes in a single tablespace or should I make two tablespaces and separate them. In some queries, the indexes may be used together but in most they will not. If I put them in a single tablespace, will that cause I/O contention.
This is on 8.0.4 Sun E10K Solaris 2.6 with Veritas Quick I/O.
Thanks,
