Future Webinars

What a z/OS Guy Learned About AWS in 10 Years ..... TUESDAY June 25th ..... Sign up using this link

At Enterprise Performance Strategies, we’re some of the best in the world at helping people understand, improve, and manage the performance of their z/OS systems. When Scott Chapman joined EPS in 2014, he brought with him over 20 years of managing IT in a z/OS environment but then had to shift to AWS. Over the past 10 years as both EPS and the AWS offering catalog have grown, Scott has formed a few opinions and observations of AWS that may be of interest to those who have a mandate for migrating part or all their mainframe workload to the cloud. Spoiler alert: not all grass is greener on the other side of the fence.


Advantages of Multiple Period Service Classes ..... July 10th ..... Sign up using this link

The ability to have and manage workloads in multiple period service classes has been around since the very first days of WLM. In fact, multiple period service classes are a continuation of the ancient multiple period performance groups of early MVS. However, the use and managing of multiple period service classes has evolved. During this webinar, Peter Enrico will review and discuss some advantages of using multiple period service classes in the year 2024.


Understanding z/OS Connect Measurements ..... July 24th ..... Sign up using this link

Do you have z/OS Connect? Are you aware of the performance measurements available for it? Do you understand them? In this webinar, Nancy DiFilippo will explain and explore the different SMF records that can be cut by z/OS Connect, with a focus on what record types you should enable and how to make sense of the resulting data.


WLM and SMF 99.1 – System Measurements Deeper Dive ..... August 14th ..... Sign up using this link

The SMF 99.1 record has been around since the first availability of WLM. It contains system level data, the trace of SRM actions, data about resource groups, and a whole host of other measurements. The SMF 99.1 records system levels details used by the WLM policy and resource adjustment algorithms. During this webinar, Peter Enrico will walk through the measurements of the SMF 99.1 record and show how these measurements can be used. During this webinar, the attendees will also gain insights into the WLM policy adjustment algorithms and how they work.


WLM and SMF 99.2 – Service Class Period Measurements Deeper Dive ..... August 28th ..... Sign up using this link

The SMF 99.2 record has been around since the first availability of WLM. It contains service class period measurements by the WLM policy and resource adjustment algorithms. During this webinar, Peter Enrico will walk through the measurements of the SMF 99.2 record and show how these measurements can be used. During this webinar, the attendees will also gain insights into the WLM policy adjustment algorithms and how they work.


Optimizing Performance at the Speed of Light: Why I/O Avoidance is Even More Important Today ..... September 11th ..... Sign up using this link

Long gone are the days of the mainframe processors having relatively low processor speeds and relatively small memory sizes. The modern mainframe can have TBs of memory, and the processor clock speeds are among the fastest in the world. Fast processors wait at the same speed as slow processors, but the opportunity cost of waiting is higher. Optimizing processor performance today is all about keeping data as close as possible to the CPU core and reducing the instruction count needed to get to a piece of data. In this webinar, special guest Larry Strickland from Data Kinetics will join Scott Chapman for an interesting discussion into why I/O avoidance is more important today and different ways that can be accomplished.


Understanding MVS Busy % versus LPAR Busy % versus Physical Busy % ..... September 25th ..... Sign up using this link

During this webinar, Peter Enrico will explore the SMF 70 processor dispatch measurements and the formulas that these measurements are used with to calculate physical and logical and MVS processor utilizations. Also discussed will be the conceptual difference and usage between physical and logical utilizations.


Rethinking IBM Software Cost Management Under Tailored Fit Pricing ..... October 9th ..... Sign up using this link

Are you considering moving from the rolling-4-hour average (R4HA) MLC pricing to the consumption model of Tailored Fit Pricing (TFP)? Or maybe you have moved from R4HA to TFP already and are now wondering about how to better manage your bill. Or maybe you’d just like an update on what TFP is and if you should consider it. In any of those cases, come to this webinar wherein Scott Chapman will review TFP and what we’ve been hearing from IBM and customers about it. He’ll also explain how you must change your thinking about managing workload for optimal software cost management when moving from R4HA to TFP.


Understanding Page Faults and Their Influence on Uncaptured Time ..... October 16th ..... Sign up using this link

This webinar is a back-to-basic webinar about memory management and page faults. Recently, there has been talk about the influence of first reference page faults and their influence on uncaptured time and capture ratios. Since uncaptured time translates to MSU consumption, it is always interesting to explore what contributes to these MSUs. Besides, what is the difference between a demand page fault and a first reference page fault? After attending this webinar with Peter Enrico, you will be more familiar with z/OS memory management, page faults, and uncaptured times.


Response Time Goals: Average or Percentiles? ..... November 20th ..... Sign up using this link

In this webinar, Scott Chapman will discuss why one would want to use response time goals and the difference between using average and percentile response time goals. While percentile goals are used far more often than average goals, there are situations where average goals may be more appropriate. After this webinar, you’ll have a better appreciation for when average response time goals provide better transaction management.


Understanding and Using Enclave Measurements ..... December 11th ..... Sign up using this link

Enclaves on z/OS are used for a variety of purposes, but the most common usage is for DB2 DDF transactions. Recently, additional and new enclave measurements have been added to the SMF data to help understand enclave transactions performance and CPU usage. During this webinar, Peter Enrico will review the concept and usage of enclaves. Then, he’ll provide an inventory of the most useful enclave measurements and how those measurements can be used to evaluate the performance of your enclave workloads.
