Seminar Abstract and Outline

Audience:

This 4-1/2-day seminar is for any performance analyst, capacity planner, or systems programmer responsible for performance measuring, monitoring, and tuning IBM's z/OS systems and sysplexes.

Please do not hesitate to contact Peter Enrico if you have any questions regarding this seminar or others.

A Week of Reviewing Your Own Data!

Prior to class we instruct you on what data to bring to class from your own systems. Then, while in class, you will also be spending a week doing an actual Sysplex and z/OS system performance Health Check® using the data you supplied. So if you have not done a Sysplex Health Check® in a while, or have some performance nagging questions, this is a perfect opportunity for combined instruction, time doing analysis, and an opportunity to get input and recommendations from a leading zArchitecture and Sysplex performance expert – Peter Enrico.

Seminar Abstract:

IBM's z/Architecture platform continues to evolve at a rapid pace. It can be a full time effort just to keep current with the latest technologies, performance management techniques and measurements. This is especially true with the most recent 'z' announcements. Like our other classes, students will spend not just a week learning, but also a week analyzing their own data.

This unique class, developed and taught by Peter Enrico, provides you with an incredible wealth of information to help you effectively manage the performance of your z/OS systems running in a sysplex or parallel Sysplex environment.

Parallel Sysplex is an important topic in this seminar. After a review of the basic concepts of XCF, parallel Sysplex and data sharing, attendees will learn about the latest coupling facility configuration options and data sharing exploiters. Attendees will also learn to effectively measure, monitor, and tune coupling facilities and structures. During the class exercises each attendee will analyze their own XCF and coupling facility data.

Other areas of instruction and analysis will include advanced processor performance, processor storage analysis, and the most recent changes related to z/OS WLM management.

During this performance seminar Peter will also help you to make sense of the most recent 'z' performance related announcements that, as performance analysts, you need to know to get the most out of your environment.

And remember... as with all our performance seminars, during class you will be analyzing your own data during the class exercises. Peter will also provide you real-time feedback. So please remember to think of this class not just as a week of instruction, but also as a week of doing a real performance analysis.

After attending this seminar you can return to work, roll up your sleeves, and start to effectively measure, monitor, and tune your z/OS system, with extra emphasis on parallel Sysplex.

Seminar Objectives:

Processor, Storage, and Parallel Sysplex Performance

Although introduced in the mid-1990s, parallel sysplex and data sharing are still a driving force at many installations, helping manage the ever increasing z/OS workload growth. As these continuously available application and database workloads grow, so do the parallel sysplexes that provide the underlying infrastructure.

If you are already running a parallel sysplex or are considering one, this section of the seminar provides you with the latest performance monitoring and tuning information.
