I think that indexing the 'profile' table on entpc and laccess could be a good thing to start with. Probably some work to do on MSG_HISTORY as well. You are right about bind variables, but it won't help the queries on MSG_HISTORY, where the long string of ORs is obviously dynamically built. Oracle doesn't often choose to iterate as it should with a long string of ORs (or a long IN list), the 'FIRST_ROWS' hint may help. You can also tell your developers to review the English irregular verbs, especially 'to send'. Forget about the magical INIT parameter. -- Regards, Stephane Faroult Oriole Software -- Please see the official ORACLE-L FAQ: http://www.orafaq.net -- Author: Stephane Faroult INET: [EMAIL PROTECTED] Fat City Network Services -- 858-538-5051 http://www.fatcity.com San Diego, California -- Mailing list and web hosting services --------------------------------------------------------------------- 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).
