John, Do you have the SERVERS service class or the transaction response time service class marked as CPU Critical? I would have thought it would be the SERVERS service class since it's the server task that gets the resources. However, in my review of the WLM System Programmers Guide it looks like their example has it set on the transaction response time service class Tom Kelman ***************************************************************************** If you wish to communicate securely with Commerce Bank and its affiliates, you must log into your account under Online Services at http://www.commercebank.com or use the Commerce Bank Secure Email Message Center at https://securemail.commercebank.com NOTICE: This electronic mail message and any attached files are confidential.
