Can you translate the word "paused" into a wait event? What is the session waiting for? Did you look into V$SESSION_WAIT? Is there any difference in the execution plans? Just a word of advice, disabling the primary key is usually not a good idea, because it might help you with distinguishing one record from another. Without the primary key it's much harder to tell records apart. -- Mladen Gogala Oracle DBA -- Please see the official ORACLE-L FAQ: http://www.orafaq.net -- Author: Mladen Gogala 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).
