There are some items I don't know enough about yet to gauge the
- Workload Manager is used to throttle back the z/OS LPARS below a
specified 4 hour rolling average of CPU usage (for cost reasons).
I've never used Workload Manager, but wonder: (a) will it work if
z/OS is a guest of z/VM, and (b) if not, what would accomplish the
same thing? Setting SHAREs is obviously not up to the task because
we're talking about the whole CP side.
Unless all of the z/OS images on the machine (guest or LPAR) are at the- Workload Manager is used to throttle back the z/OS LPARS below a

z/OS 1.7 level then running any z/OS guest under z/VM will cause the
software charges for the z/OS guests to be levied against the size of
the VM LPAR and not against the 4 hour rolling average utilization.
Please see Chapter 5 of SG24-6522-16 Using the Sub-Capacity Reporting
Tool (aka the SCRT User's Guide)for more information.
