Reporting and analysis with IMS Performance Analyzer

In-depth analysis and reporting of IMS™ Connect event records is provided by the IBM® IMS Performance Analyzer.

IMS Performance Analyzer for z/OS® is a performance analysis and tuning aid for IMS DB and IMS TM systems. It processes Log, Monitor, and IMS Connect event data, to provide comprehensive reports for use by managers, database administrators, communications administrators, and system programmers to analyze and tune their IMS systems.

IMS PA is a tool for managers, system programmers, and technical support personnel. It produces management-oriented reports and it produces summary and detailed information for those directly involved in improving system performance. IMS PA can help you:
  • Improve system performance
  • Improve transaction transit time to manage TCP/IP communication more efficiently
  • Use IMS regions and message queues more efficiently
  • Reduce virtual and real storage requirements in buffer pools
  • Increase the availability of IMS resources
  • Evaluate applications and programs against system standards before installation
  • Do ongoing system measurement and management reporting
  • Debug IMS applications
  • Increase the productivity of analysts and programmers
  • Determine future system requirements
  • Enhance system and program documentation
  • Reduce the need to run IMS utilities
  • Reduce the requirement to run the monitor reports supplied with IMS
  • Provide auditors with valuable data for a number of potential audit tasks

IMS Performance Analyzer provides a comprehensive set of reports from the IMS Connect performance and accounting data collected by IMS Connect Extensions. The reports provide a summary and detailed analysis of IMS Connect transaction transit time, resource usage and resource availability.

The IMS Connect transaction index is generated by IMS Performance Analyzer from IMS Connect Extensions journals. It collates all the information that can be known about the transaction from the available IMS Connect Extensions journal records. This information may include the client ID, IP Address, overall performance, timings of significant events, IMS Connect-exit specific performance, and dozens of additional pieces of information. You can use this index as both a reduced form of the IMS Connect Extensions journal and as input to IMS Problem Investigator and IMS Performance Analyzer.

IMS Performance Analyzer groups reports by functional category:
  • Transaction Transit Reports
  • Resource Usage Reports
  • Trace Reports

Selection Criteria enable you to filter your reporting, for example to include data only for a particular Transaction code, user ID, datastore and only for a specific period of time.

The following sections provide some examples of using IMS Performance Analyzer reports in IMS Connect performance analysis and tuning. For further information, see the IMS Performance Analyzer Report Reference.
