Hi Al and Horst, I found the source of my impression that IRD weight management is also being stopped by 'softcapping'.
The document is " z/OS Workload Management Update for z/OS V1.11 and V1.12" by Horst Sinram IBM Germany Research & Development August 2, 2010. Sheet 17 (Group Capacity: Summary) states: Working with IRD CPU Weight Management • Defined and Group Capacity work with IRD but Weight Changes are only possible for partitions which are not being capped (or subject to capping) This at least suggests that IRD Weight Management is also disabled when an Lpar is softcapped by DC limits and not only by GC limits. Horst, Can you clarify this?

Agreed. I was under the impression, but not sure, that IRD also stops adjusting weights when DC is softcapping an LPAR. I have been trying to find where I read that, but as usual IBM has messed up (reorganized) its website again, so all my links return only 404's. On the other hand, I recently talked to another site, who are using zCOST (which manipulates DCs) and IRD together and AFAIK they did not have problems with the combination.
