If you are using any capping, you best have a very well defined WLM Service Policy.

We use PRSM's "Group Capacity" to limit our software bills by limiting our MSU usage. This is done by PRSM "capping" the LPAR when the MSU usage starts exceeding the 4 hour rolling average limit. However, one can "build up credit" with PRSM by have a longish period of low MSU usage before a spike period. For a time, PRSM will allow the LPAR to exceed the specified "Group Capacity" limit. So we try to schedule our work in such a way that we stay below this limit. The reason being that we might need the "spike" in case of a "hot" job coming in. Or for extra power in case of an abend. -- There is nothing more pleasant than traveling and meeting new people!
