why dont you check the v$transaction to see whether it is rolling back or i mean it is still active.
Sometimes if a process is doing lots of reads on the database and causing lots of cpu spike it would be better you kill the process from the database first and then from the side unix also,we had these issues and  had to kill those processes on the unix side also otherwise they keep taking resources.

Rebounce the database...After shutting down database , check for any oracle process is still alive by usingipcs -mbIf it is still their kill those process by yourself (using ipcem -m ) or by Unix admin. Sometime it does not go and then you have to reboot.If shutdown immediate takes longer then use shutdown abort. Recovery will not take longer at startup.RegardsRafiqReply-To: [EMAIL PROTECTED]To: Multiple recipients of list ORACLE-L Date: Wed, 11 Jun 2003 14:04:21 -0800OS :hp-uxoracle rdbms are certain processes taking lot of cpu ( some thing went wrong with stastics last nite). which is causing almost a halt in production database.these processes are killed from oracle but i can still see them on OS .Cpu is still high .I though!  after

 killing them mpon might be doing some clean up work .cpu is still high .question : If I recycle this instance ,is it going to take long time to come back . ( smon will do the job now ?)or is "fast warm start" will help here to bring db up quickly?thanks,-Ak_________________________________________________________________STOP MORE SPAM with the new MSN 8 and get 2 months FREE* Please see the official ORACLE-L FAQ: Author: M RafiqINET: [EMAIL PROTECTED]Fat City Network Services -- 858-538-5051 http://www.fatcity.comSan Diego, California -- Mailing list and web hosting services---------------------------------------------------------------------To REMOVE yourself from this mailing list, send an E-Mail messageto: [EMAIL PROTECTED] (note EXACT spelling of 'ListGuru') and inthe message BODY, include a line
