Home -> Community -> Mailing Lists -> Oracle-L -> RE: Size of segment
Charlie,
I think conventional wisdom suggests splitting data and index onto separate
disks rather than separate tablespaces.
Just to start the unsubstantiated anecdotal evidence I've seen this help on
more occasions than I care to recall.
I'm the first to agree though that separating data and indexes into separate
tablespaces won't help if they're on the same disks. It will make them
easier to split in future though.
Regards,
Mike Hately

There is/was a recent and active discussion of this topic in the Oracle Server Usenet forum.
While it has long been "recommended" that tables & indexes be placed in separate tablespaces, the current conventional wisdom disputes the claim that performance can/will be enhanced by separating data and indexes into different tablespaces.
If anybody can produce recent benchmark results which shows that separating index & data into different tablespaces improves performance, I'd like to see the details behind the benchmark and the results.
