Uses

This query is used to determine if the zIIP engines in a CPC are sufficient to handle the zIIP eligible workload running on z/OS LPARs. Even if no zIIP engines are present in a CPC, the charts show z/OS LPAR zIIP eligible work that executed on CP engines. zIIP engines are less expensive that CP engines. Reducing CP engines in a CPC can reduce software licensing fees. In general, if significant zIIP eligible work is executing on CP engines, it is cost effective to add zIIP engines to the CPC.

Note: If a CPC has one or more zIIP engines and no zAAP engines, and has specified ZAAPZIIP=YES in SYS1.PARMLIB, zIIP engines process all specialty engine work—including work that would normally run on zAAP engines. In this environment, all SMF and RMF metrics treat zAAP and zIIP eligible workloads as zIIP eligible. No zAAP actual or eligible demand appears.
