Yes exactly, that is part of what WLM is designed to do. In the real world most shops use WLM service classes and velocity goals to control things like CPU dispatching frequency. I'm sure there exist workloads which tend to defy the controls available in WLM, but I suspect they are quite rare. In all but those rare instances, I'd be inclined to steer clear coding something in a program for the purpose of getting it re-dispatched for some resource.

Caution! This message was sent from outside your organization. Why? If you are waiting for something then you should use system services, e.g., ENQ, WAIT, to delay until it occurs; if you are not waiting for something then why not let the WLM handle what it's designed to handle? -- Shmuel (Seymour J.)

Does anyone happen to know the best way for a running task to give up running and let another task run? But - this isn't "give up" as in ending the task, just giving up the CPU to allow another task to run and then returning to this task. Sorta like "I'm done for the moment if something else would like to run". - Thanks - - Dave R. - -- riv...@dignus.com Work: (919) 676-0847 Get your mainframe programming tools at http://secure-web.cisco.com/1aWH_FeYH8IlEwirJURk9sI7agw2X83FuMWKAE73bQgFjnWwW8-ePX_1xe1c0wvYZd8fcSnekzTSoxHccH5VLqo1rFCH9l3YX-k05mc9h6Ase64ekfUJQccKN7CoeKCb4mPWA65v0tvTLbXvBj_NDoce9MeFrZe7fZoePl7rSLNfSTkWiZtNoKrgNjJAaR56QKA_GzYAnQG1J3QqwTGR2aaONvJRqOZStLx-dDHLw-ANzfr-JqBhHVtxkPlrsOeTXQ5nr8kcqRcEdVKERvT0cBrDKRHbq59tsrJEPtz1qMjVK741J5WNN9JBdkVQ8CVHDOJsDhzqP_OSlWPU3JX2BtgFEtR-6t6ZDm5b1JEGSDbqulEaUL7WgUU6iBjImRoscWih5c4GWGVq3XTLgBcJli_t27401y41mmE7SVQ5PT5JfB_KovcV3dinUMhketMyr/http%3A%2F%2Fwww.dignus.com ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
