I think you are suggesting that any task that is part of such a workload be (potentially) reclassified every time it is selected for dispatch. If selected for dispatch on a ZIIP, it would go to the original service class. If selected to be dispatched on a GP it would be reclassified to the pther service class. What do you think should happen if the address space has multiple tasks and some are running on ZIIP and some are running on GP? -- Tom Marchant ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
