Shu, IOTs are not, whether they are partitioned or not, any more than anything else, the answer. They are an answer to some special queries which are highly important to your application (and, possibly, reasons linked to ease of operation). If non-partitioned performs better, go for non-partitioned. The only problem I am aware of with partitioned IOTs is that you may have deadlocks with SELECTs if you are concurrently partitioning them (true in both 8.1.6 and 8.1.7). -- Regards, Stephane Faroult Oriole Ltd -- Please see the official ORACLE-L FAQ: http://www.orafaq.com -- Author: Stephane Faroult INET: [EMAIL PROTECTED] Fat City Network Services -- (858) 538-5051 FAX: (858) 538-5051 San Diego, California -- Public Internet access / Mailing Lists -------------------------------------------------------------------- To REMOVE yourself from this mailing list, send an E-Mail message to: [EMAIL PROTECTED] (note EXACT spelling of 'ListGuru') and in the message BODY, include a line containing: UNSUB ORACLE-L (or the name of mailing list you want to be removed from).
