CPExpert is a software program that runs on your IBM mainframe, analyzing data in your MXG®, MICS®, or SAS-ITRM® performance data base. CPExpert runs as a normal batch job, and it: Reads information from your system to detect performance problems. Consolidates and analyzes data from your system (the data normally is contained in a performance data... base) to identify the causes of performance problems. Produces narrative reports to explain the results from its analysis, and to suggest changes to improve performance. CPExpert is implemented in SAS®, and is composed of hundreds of expert system rules, analysis modules, and queuing models. CPExpert has different components to analyze different aspects of system performance. Breaking the product into "components" allows you to license only those analysis modules that meet your performance analysis needs. When CPExpert was introduced in 1991, the product provided analysis of IBM performance problems that existed prior to Goal Mode. The analysis provided with CPExpert have changed since the product was initially released and the components that apply only to MVS Compatibility Mode are no longer marketed. While these "legacy" components are not marketed, they are described at the end of this page to give you an appreciation of CPExpert's history. The following five components now are provided with CPExpert: The DASD Component was introduced in 1991. The DASD Component identifies DASD volumes with the most significant performance problems and suggests ways to correct the problems. The DASD Component has been enhanced over the years, to include other DASD analysis (such as cache controller analysis, VSAM analysis to automate most of the analysis contained in IBM's VSAM Demystified Redbook, etc.). The CICS Component was introduced in 1992, supporting early versions of CICS. The CICS Component now analyzes standard CICS interval statistics, applying most of the analysis described in IBM's CICS Performance Guides. All versions of CICS are supported (including CICS/TS for ...Read More
