CICS PA -- Account for hardware changes in the CICS environment

In CICS PA reporting there is no consideration for changes to the hardware environment. We need the reports to include a consideration for the hardware change so we are able to more readily determine if the change in the application performance is due to hardware changes or application changes.

    Note that APAR PM84724 provided the capability to report CPU time as Service Units. A new derived field is provided CPUSU which is CPU Service Units as calculated by CICS PA based on the hardware system where the SMF data was collected. This can be used for comparison of reports across two different hardware environments. Therefore, if you upgrade you hardware to the next generation of z processor and you have SMF data from the previous generation z processor then you can use the CICS PA CPUSU field in a form to compare the performance of the transactions across the 2 hardware environments. CPUSU is calculated using a conversion factor. This conversion factor can be specified at the MVS Image level or at the SMF file level. If you have SMF data for the same applications and transactions but across 2 different hardware environments then CPU time as service units can be used to get the correct performance comparison. Please refer to Chapter 12 of the CICS PA User's Guide for further details on CPU Service Units.
