Uses

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