Recommendation can be: Hardcap test system at niGth , usinG SA- BCPII interface. On effect of LPAR , try zPCR maybe already did, you will see how much ITR value will increase by decreasinG useless LPARs. On the other hand, IPL and stop ,I think always should be done by someone in office, there can be unknown problems ,since CEC is same.... I would prefer to make process automatic to put hardcap. reGards Meral.

I would agree. I see no reason to bring down an LPAR for production. If you are worried about test machine use overnight, you can schedule turning off initiators or putting all batch jobs to sleep, or, you can even simply give a huge weight to production for the CPU so that it always gets most of the priority. You can also use CPU affinity on the test lpar to minimize contention with production. In short, there are a lot of things you can do without having to bring down the whole lpar.

Anyone have a product or written an API? We would like to activate our test lpar (monoplex) at 7am so when we get in at 8am, the system is up. We can't leave it up overnight because we need the cpu to do heavy production processing. -----------------------------------<unsnip>------------------------------ Why not just leave it up? An idle z/OS image only consumes a small percentage of the CPU. If you're that close in getting your night production finished on time, perhaps an upgrade is on the horizon. How efficient are the programs used in that night production? How old are they? Ditto for the JCL. At Clearing, we moved two statements in a COBOL program and cut the run time from over 4 hours to under 20 minutes.
