BMC's MAINVIEW for z/OS 2.9 schedules SRBs eligible for zIIP processing based on an installation specified parameter, regardless of the PROJECTCPU setting and/or the existence of zIIPs. However, there is a limitation with PROJECTCPU's numbers. z/OS does not provide zIIP on CP usage by JOB (Address Space) in any documented (GUPI or otherwise) field. They are only available at the WLM workload level and individual enclaves via the WLM APIs.
