Short Summary

This advanced course is for experienced IMS system programmers or performance analysts responsible for the performance of a large-scale IMS DB/DC system.

Duration in Hours ⌚

24.0

Content Description

Learn a methodology to improve the performance of a large-scale z/OS IMS/TM data communication system. This course explains the impact of user-specified options on IMS performance, how to determine performance bottlenecks by interpreting information from certain performance reports, and how to use the information gained to implement a plan to improve the performance of an IMS system.

Objectives

  • Create and implement a performance improvement plan based on the methodology presented
  • Discuss the performance options available to the IMS user
  • Describe the performance impact of the IMS storage pools and datasets and their interrelationships
  • Interpret the information contained in performance reports
  • Analyze the performance reports to determine performance bottlenecks in the IMS system

Agenda

  • Monitoring and Tuning Overview
  • IMS Structure and Major Control Blocks
  • The IMS Logger and Pool Management
  • IMS Communication Component
  • IMS OTMA (Open Transaction Management Access) Communication Component
  • z/OS Considerations for IMS
  • IMS Scheduling
  • IMS Program Loading Options
  • IMS Program Elapsed Time
  • IMS Database Buffering
