I went the other way. All of our CICS's run with a transaction response time goal except two. We have a third party CICS application that performs huge numbers of I/O's. A transaction response goal is impossible to satisfy in this region, so we run those with a velocity goal. Lots of trial and error before I understood what was happening and got this one performing reasonably. If your CICS region does transactions that require a lot of I/O, WLM may be taking the I/O into account when determining whether the workload is attaining its goal. With I/O priority management turned on or an I/O coefficient specified, you probably won't be able to achieve a 50% velocity. You may have to increase your velocity goal to get that kind of CPU time. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
