DISTUCP

Use the DISTUCP command to request the distribution of unaccounted CPU to all workloads.

Warning

Important

Unaccounted CPU is the portion of total CPU time consumed in a z/OS image that was not allocated by RMF and SMF to any particular Performance Group, Service Class, and address space. It usually is the time spent for some system tasks, such as interrupt processing, context switching, paging, and so on. However, even though this CPU time is not allocated to any specific tasks by RMF/SMF, it was spent on behalf of all tasks performed in the system. As a result, by default, UIE distributes unaccounted CPU to all workloads.
