Parallel Sysplex Aggregation


Sysplex Calculator (PLEXCALC) Overview

The Sysplex Calculator is a new, no-charge, downloadable tool from IBM that can help you assess whether your Parallel Sysplex qualifies for aggregation. This tool is designed to analyze Systems Measurement Facility (SMF) data from two or more machines and produce a report describing which Parallel Sysplex each machine belongs to, if any, based upon the 50 percent criterion stated on this website.

The Sysplex Calculator is designed to analyze SMF data from any mainframe running an eligible operating system that generates RMF-compliant SMF70 records. While the Sysplex Calculator is designed to assist you in determining eligibility for Parallel Sysplex Aggregation, final eligibility determination can only be made by IBM through your IBM representative.

Updated 11 October 2013 The Sysplex Calculator has been updated to fix a bug which caused LPARs which had not been used to be reported as missing data.

Updated 21 August 2013 The Sysplex Calculator has been updated to support the new IBM zEnterprise BC12 (zBC12) processors.

Updated 31 March 2013 The Sysplex Calculator has been updated to fix a bug in reporting zIIP/zAAP MSUs on the IBM zEnterprise EC12 (zEC12) processors.

Updated 28 August 2012 The Sysplex Calculator has been updated to support the new IBM zEnterprise EC12 (zEC12) processors.

Updated 27 September 2011 The Sysplex Calculator has been updated to support the new IBM zEnterprise 114 (z114) processors.

Updated 26 August 2010 The Sysplex Calculator has been updated to correct an error in its calculations in certain circumstances on the new IBM zEnterprise 196 (z196) processors.

Updated 22 July 2010 The Sysplex Calculator has been updated to support the new IBM zEnterprise 196 (z196) processors.

Updated 17 September 2008 The Sysplex Calculator has been updated to correct a formatting error some users discovered when reporting data from zAAP/zIIP engines on z10 machines.

Updated 28 November 2007 The Sysplex Calculator has been updated to correct a formatting error some users discovered when reporting data from zAAP/zIIP engines.

Updated 13 March 2007 The Sysplex Calculator has been updated to correct a small bug some users discovered when specifying the lunch hour parameter.

Updated 2 February 2007 The Sysplex Calculator has been updated to more clearly take into account the workload dispatched onto System z Application Assist Processors (zAAPs) and System z9 Integrated Information Processors (zIIPs). Additional lines will be displayed in the Sysplex Calculator Report when zAAP or zIIP engines are found to be present.

Updated 19 December 2005 The summary statements in the header of the Sysplex Calculator Report have been updated to more clearly specify the PrimaryPlex for each machine analyzed. A sample report is available in the Sysplex Verification Package.

Updated 27 October 2005 The Sysplex Calculator has been updated to more accurately reflect IBM's true intention regarding Parallel Sysplex Aggregation criteria. The key changes are as follows:
