-----Original Message----- Sent: Thursday, December 26, 2002 9:14 PM To: Multiple recipients of list ORACLE-L Though I have published a script for determining indexes that need to be rebuilt, and then rebuilding them, I have to say that this is almost never necessary. Why are you rebuilding indexes? About the only reason for ever doing so is that the BLEVEL >= 5. go to asktom.oracle.com, and do a search on 'index rebuild'. Currently, the third article may be of interest.

Thanks.

That is all I can think of. Why do you ask? Jared has spoken eloquently about how frequent index rebuilds can reduce your performance. -- Please see the official ORACLE-L FAQ: http://www.orafaq.net -- Author: Guang Mei 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).
