I agree that ones has to make intelligent decisions based upon their
environment. I do not endorse capping a shared CF, but if you do not have
the available CPU capacity to dedicated a full CP it might work. However,
you have to be careful or else you can kill production.

Subject: Re: DASD: to share or not to share
I do not cap my CF LPARs, except that they are limited to only 1 CP. I
define a weight such that they are guaranteed a full CP, yet they never use
a full CP, since they are using dynamic dispatching. This configuration is
not going to hang my production LPAR, and I believe it is silly to suggest
such a thing.
Would I get better CF response time if I had dedicated CPUs for the CFs
(ICF or CP)? Yes, of course. Would I try to do DB2 data sharing in this
configuration? No, of course not. One has to make informed intelligent
decisions in this business, isn't that our job?

Does not "cap it CF LPAR" ask for or equal "hang production LPAR(s)"
waiting for CF response?
