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.

• 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

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

You should have moderate level of knowledge of IMS/TM which can be gained through work experience or through completing the IMS System Programming: Database and Transaction Management - ILO (CMW11)

• 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

Prior to enrolling, IBM Employees must follow their Division/Department processes to obtain approval to attend this public training class. Failure to follow Division/Department approval processes may result in the IBM Employee being personally responsible for the class charges.

GBS practitioners that use the EViTA system for requesting external training should use that same process for this course. Go to the EViTA site to start this process:http://w3.ibm.com/services/gbs/evita/BCSVTEnrl.nsf

Once you enroll in a GTP class, you will receive a confirmation letter that should show:

• The current GTP list price
• The 20% discounted price available to IBMers. This is the price you will be invoiced for the class.
