Alan, I disagree.
Yes, you still have the possibility of a resource shortage. However, partitioning provides the installation more flexibility in protecting critical resources. As far as how should CP respond, if sufficient page space is unavailable within a particular backing storage pool according to the criteria set forth, then the request (LOGON, DEFINE STORAGE) should be denied.

How should CP respond? o Deny the request? o Wait for the resources to be available? o Steal the resources from someone else? You can partition and reserve all the resource you want, but eventually you run out. Alan Altmark z/VM Development IBM Endicott
