Pivotor in Action: A Live Look at Mainframe Performance Reporting ..... Sept 23rd ..... Sign up using this link

This hour-long webinar is for people who might be interested in Pivotor, as well as current Pivotor customers who want a refresher on the user interface. Peter Enrico and Scott Chapman will demonstrate how Pivotor simplifies z/OS performance analysis while providing the toolset to support in-depth analysis. If you haven’t looked at Pivotor in a while, expect to see a few features you might have missed or forgotten about.

z/OS Performance Topics: The Ones That Divide Us ..... Sept 30th ..... Sign up using this link

Recently presented at SHARE Pittsburgh 2026! Some performance recommendations are clear-cut. The ones that aren't are the “fun” ones! Should you set WLM goals aggressively or leave room? Are percentile response time goals always preferred over average goals? Should you include zIIPs and GP CPU together when calculating certain measures? What zIIP or GP utilization is “too high”? Reasonable people disagree on such questions, and the right answer often depends on your workload, your shop, and possibly which “performance camp” you belong to. Scott Chapman and Peter Enrico are back with a fresh set of performance controversies for 2026. They'll stake out positions, which may not always match each other or other experts in the field. Some pet peeves may be aired. Don't expect tidy answers — but do expect to leave with a sharper view of the tradeoffs and a clearer sense of where you stand.

z/OS Measurements - Basic to Advanced Series: LPAR and CEC Usage and Utilization ..... Oct 7th ..... Sign up using this link

"How busy is my mainframe?" is arguably the most basic performance question people want answered. And while there’s lots of ways to express that measurement, that’s only the beginning of understanding what might be impacting your LPARs’ performance. In this webinar, we’ll start at the basic CEC usage, discuss why the RMF view of that may be misleading, and move to the less-reviewed but important measurements before finally exploring some measurements that you might not have thought to look at before. Join Scott Chapman as he breaks down these measurements and shares what he’s learned from reviewing hundreds of LPAR configurations over the years.

z/OS Measurements - Basic to Advanced Series: I/O: Response Time and Beyond ..... Oct 21st ..... Sign up using this link

We don’t have I/O problems anymore because we all have fast solid-state storage, right? Well… maybe not. In this webinar, Scott Chapman will discuss the traditional I/O measurements commonly surfaced in the RMF data, discuss the “hidden” measurement that impacts the actual response time, and finally look at the I/O measurements from other SMF records to get a deeper understanding of why I/O may be impacting some workloads despite an overall good I/O response time measurement.

z/OS Measurements - Basic to Advanced Series: What Are My Service Classes Doing? ..... Nov 18th ..... Sign up using this link

Workload Manager (WLM) manages work in z/OS by service class period (SCP), so it stands to reason that you should understand what your service classes are doing. You probably are familiar with the measurements for how much CPU each SCP is consuming, or how many transactions are being executed, or even the response time for those metrics. But WLM really manages the work by PI (Performance Index). Do you know that the PI is derived from samples? Those samples reflect the characteristics of the work, including what may be impacting the performance of the work. In this webinar, Peter Enrico will lead you on a tour of the measurements that help you understand how WLM is looking at and managing your workloads.

z/OS Measurements - Basic to Advanced Series: Coupling Facilities ..... Dec 9th ..... Sign up using this link

If you have a Parallel Sysplex, your coupling facility (CF) performance is an important component of your overall sysplex performance. Even the basic coupling facility measurements can be confusing and complicated: how many different ways are there to calculate CF CPU utilization, and which one should you really pay attention to? What other measurements are indicative of the overall health and performance of your sysplex? Come to this session to find out. Join Peter Enrico as he walks through these measurements and helps you understand what really matters for your sysplex's health.
