Hi Timothy
I haven't heard of that either. I was thinking of vendors that license for less

full capacity for a specific number of MSUS or MIPS.

Wouldn't a defined capacity setting (a.k.a. softcap), group and/or

We use Group Capacity to group our two LPARs together in a
single capacity group. We then tell PR/SM how many MSUs
these two LPARs together may use. PR/SM works with WLM

Yes, Defined Capacity and Group Capacity Limits can do this, but not *all*
vendors. For many vendors, but not for all. Hence some sites are using these
other techniques.

LPAR Group Capacity Limits came with z/OS 1.8, so that should be available to
most sites. Requires z hardware. What some customers have not understood is
you are allowed to have multiple LPAR Groups on a single machine and they are
able to work across sysplex boundaries.
So some sites use one
I haven't heard of vendors that both have sub-capacity licensing and then
proceed to define sub-capacity differently than the four hour rolling
average. But I suppose anything is possible. (A 3.28 hour rolling average?)
I'm still not sure what the use case is for a dummy LPAR, though, at least
Does anyone use the concept of a dummy LPAR to store excess MIPS to avoid

Suggest other methods of storing unused capacity?
