This course of 6 sessions, 4 hours each day, teaches a  methodology to tune a large-scale z/OS IMS/TM data communication system. Specifically, 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 implement a plan to improve the performance of an IMS system.


  • 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 data sets and their interrelationships

  • Interpret the information contained in performance reports

  • Analyze the performance reports to determine performance bottlenecks in the IMS system
