CA MICS Hardware and SCP Analyzer (RMF) Queries › Mainframe CPC Configuration › RMFWGT – CPC LPAR Relative Weight by Engine Pool › Overview

Overview

The RMFWGT query shows the relative dispatch hierarchy for the shared LPARs defined to a CPC, based on the system programmer specified weights for each LPAR. LPAR weights are designated for each logical processor engine type assigned to each LPAR.

In the example, the fourth LPAR from the left, "CA31" has three logical processor engine types assigned—CPs, zIIPs, and zAAPs. Relative to the other LPARs defined to the CPC, the weights assigned to "CA31" tell PR/SM that when there is contention for the physical engines, "CA31" dispatches physical engines to handle its workloads about 30 percent of the time (for CPs) and 33 percent of the time (for zIIPs and zAAPs). For the two LPARs that use IFL engines (green vertical bars), "SYSC" and "VMZ", when there is contention for the IFL engines, VMZ gets about 60 percent of the dispatches and "SYSC" gets about 40 percent.
