I assume you mean that ORACLE.EXE is consuming all the CPU. A couple of things to check: * Is there a lot of PL/SQL being executed on the server (triggers and packaged procedures)? * Has anti-virus software been installed? If so does it exclude the Oracle files? regards _________________________ David Kurtz Go-Faster Consultancy Ltd. tel: +44 (0)7771 760660 fax: +44 (0)7092 348865 web: www.go-faster.co.uk mailto:david.kurtz@xxxxxxxxxxxxxxx Book: PeopleSoft for the Oracle DBA: http://www.psftdba.com PeopleSoft DBA Forum: http://groups.yahoo.com/group/psftdba -----Original Message----- From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx]On Behalf Of fahd mirza Sent: 03 September 2004 09:00 To: Active DBA Subject: CPU Utilization 100% Listers, I am running Oracle 8.1.6 on windows 2k. The machine is Dell Poweredge 2500, and the no. of users are just under 100. The problem is that CPU utilization on the server has reached to 100%. I have checked and there are no blocking waits in the systems, there is no long operation. Please suggest me what can be the cause and what should I do? Is it due to any poorly written SQL, if it is , then how can I find it? Its in the emergency, I am waiting. regards, Fahd. --- To unsubscribe - mailto:oracle-l-request@xxxxxxxxxxxxx&subject=unsubscribe To read recent messages - //freelists.org/archives/oracle-l/09-2004 --- To unsubscribe - mailto:oracle-l-request@xxxxxxxxxxxxx&subject=unsubscribe To read recent messages - //freelists.org/archives/oracle-l/09-2004
