Parallel Sysplex Aggregation

Sysplex Calculator: How to Interpret Output

The output from the Sysplex Calculator job is referred to as the Sysplex Calculator Report. This report is broken in to four major sections in the following order: overview, disclaimer, summary and interval-by-interval details. Each section is explained below:

Overview and Disclaimer Sections

Summary Section

Based upon the data analyzed, the Sysplex Calculator will make a determination about which Parallel Sysplex each machine belongs to, based on the 50 percent criterion contained within IBM's Parallel Sysplex aggregation rules. A machine is said to belong to a particular Parallel Sysplex only if 50% or more of the eligible operating system workload participates in the Parallel Sysplex. For each machine, the following are the three conclusions that the Sysplex Calculator may reach, based on analysis of the prime-shift weekday intervals:

Interval-by-Interval Section

There are seven header rows shown in the Interval-by-Interval section. The first header row shows the machine for each LPAR analyzed. The second header row shows the LPAR name for each LPAR analyzed. The third header row shows the SYSID name for the instance of z/OS running in each LPAR analyzed. The fourth header row shows the System Name for the instance of z/OS running in each LPAR analyzed (this is used to correlate with the System Name in the Coupling Facility Activity Reports). The fifth header row shows the the Parallel Sysplex name for each LPAR analyzed. The sixth header row shows the average utilization contribution (in %) of each LPAR's workload, as a percentage of workload on the machine over the 40 hour prime shift period. The seventh header row shows the average utilization contribution (in MSUs) of each LPAR's workload, over the 40 hour prime shift period.

For each interval, you will see an MSU value listed for each MVS-based LPAR analyzed. The MSU value represents the average MSUs consumed by that LPAR, during that interval.
