IBM Mainframe Performance and Capacity Management z/OS 2.5 Series

The Introduction to Mainframe Performance course provides the learner with a core understanding of what performance measures are required when managing a mainframe environment. Measuring the usage of critical resources is discussed, and potential issues that can affect the performance of tasks running in a z/OS system are presented.

In this course you will examine the I/O process and see how I/O performance problems are detected, and the metrics used to determine where a problem may exist. Methods used to improve I/O performance are also discussed.

In this course you will discover how SMF is used to capture important system activity and store it as specific record types. You will see how these records are structured and the utilities used to convert their content into a readable format. Commands used to display, configure, and manipulate SMF are covered, as well as the process of archiving SMF records and creating your own SMF records. Following this, an introduction to software licensing is presented, describing common licensing models and the metrics they use to determine the cost to the customer. This information will assist the user in determining ways to minimize software licensing costs.

The Z Performance - z/OS Workload Manager course provides the learner with steps describing how WLM components are created and linked, to form a WLM policy. The course then progresses to discussing in detail various workloads and the goals and importance that should be assigned to them. This is followed by an overview of performance information that can be obtained through SMF records, MVS commands, and SDSF.
