That is my main intent. Figure out, if there are queries in one of the applications, that messes up the system. I have never done this before (I am no DBA, but follow the threads in this list, regularly), so I need some hints, on where to start and with what.

Unless the server is hung because of 100% cpu, I don't really see a problem. I would investigate for runaway queries to try and determine if anything bad is happening. But 100% utilization in itself is not an indicator of something bad happening. -----Original Message----- From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Vitalis Jerome Sent: Tuesday, August 16, 2005 9:43 AM To: Foelz.Frank@xxxxxxxxxxxxxxxxxxx Cc: ORACLE-L Subject: Re: Oracle uses 100% CPU Hi, I'm not very knowledgeable on Windows, but why a 100% CPU utilization is of any concern on a server dedicated to Oracle? Is this not what we should expect during peak periods?
