What you are describing is the behavior of WLM in a SYSPLEX. You do not say if the 2 lpars are members of the same sysplex.
EWLM (Enterprise WLM) might be of some assistance here. I am not that familiar with EWLM and its capabilities. HTH, -----Original Message----- From: IBM Mainframe Discussion List <[email protected]> On Behalf Of Pommier, Rex Sent: Tuesday, August 28, 2018 3:52 PM To: [email protected] Subject: cross LPAR priority and cycle stealing Hello list, Hypothetical scenario is a single machine with 2 LPARs on it, each LPAR is defined as having 50% of the capacity of the entire machine, uncapped across the board. In this scenario, if both LPAR1 and LPAR2 are running flat out, each LPAR will take 50% of the machine. If one of the LPARs is busy and the other isn't doing anything, the busy LPAR will "steal" cycles from the not busy one. That's the easy part. Here's where my thoughts get fuzzy. Is there a way to differentiate between high priority work on one LPAR and low priority work on the other LPAR. Here's what I'd like to do: Say I'm running a bunch of production on one LPAR and a bunch of test work on the other one. I'd like to be able to steal cycles from the test LPAR and give them to the production one. I know WLM handles this within an LPAR, making sure the high priority work gets the cycles it needs, but is there a mechanism where I can do this across multiple LPARs? If there is, can somebody point me to the right place for learning how to configure this to happen automatically? I have higher and lower priority work alternating between multiple LPARs and would like the machine to be able to better balance the workloads so that regardless of which LPAR the high priority work is on, it gets the CPU necessary.
