Have you done anything with your WLM Service Policy to support HD? Do you have much Web work? If you use HD, I would not suggest playing manual IRD. Configure each LPAR with the number of engines need to handle the peak work; the HD will park the excess as needed.
zNorman -----Original Message----- From: IBM Mainframe Discussion List [mailto:ibm-m...@bama.ua.edu] On Behalf Of Petersen, Jim Sent: Wednesday, July 14, 2010 Wednesday 11:51 AM To: IBM-MAIN@bama.ua.edu Subject: HiperDispatch isn't working on a z10 Here is a problem we opened with IBM and are wondering if anyone else has observed this as well. We have currently turned off HiperDispatch because IBM wants the CE to gather data and because of other issues, we are very uncomfortable with that. We're running z/OS 1.10 in a parallell sysplex. One of our CEC's is a 2097-717 with 4 LPARs defined. One of the LPARs is not active. The weights of the LPARs is as follows: LPAR1 - 66% LPAR2 - 20% LPAR3 - 10% The LPAR that is down is LPAR4 and is weighted at 4%. During the online day, our CPU is busy but at night there is excess capacity. The LPAR LPAR3 during the day has two CPs configured online. At 19:00 when the demand drops, we configure four more engines online. As the applications throw more work to LPAR3, the utilization gets to about 11.5% but that's it. It won't take any more even though the entire CEC is about 70-80% busy. I thought that as long as the CEC had capacity, the LPAR could take more than it's weight. When I look at the engines through our monitor, the four engines that I configured online are in a PARKED state. Is this working correctly or is there something else I should do to allow more work to flow to LPAR3 during off peak times? ___________________________________________ Jim Petersen MVS - Lead Systems Engineer Home Depot Technology Center 1300 Park Center Drive, Austin, TX 78753 www.homedepot.com email:jim_peter...@homedepot.com 512-977-2615 direct 512-977-2930 fax 210-859-9887 cell phone ________________________________ The information in this Internet Email is confidential and may be legally privileged.
