IMO using velocity goals to try to manage priorities does not let WLM do its job as effectively as if you use response goals for most of your work. Prior to Goal mode, there was nothing like a response time goal. In the case of batch work, response time is roughly the same as turnaround time. When setting response time goals for batch, it is important to use an appropriate percentile to get the workload to run the way you expect it to. If you also make as much work discretionary as possible and make sure that you don't have any unrealistic goals, WLM will maximize the throughput. Anyone setting WLM goals should be familiar with John Arwe's paper about velocity goals. -- Tom Marchant ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
