19. How long is the line, and why? Practical Applications of Queueing Theory for The Rest of Us
December 15 | Presenter: John Baker
Time: 10 AM ET | 9 AM CT | 4 PM CET
Your mainframe has the capacity to service many requests concurrently. However, as with any system, there are limits. As utilization increases, queues will inevitably develop. This session will look at the applications that are impacted, and whether you need more hardware or can optimize with tuning.
You don’t need to be a mathematician or programmer to answer these “queueing theory” questions. Join this session and learn how IntelliMagic Vision can provide clear answers to these and other questions in your z/OS environment. With direct visibility into delays and the reasons for them, as well as predictive analysis, who needs theory?

5. Lessons on Optimizing Processor Cache From z15 Upgrade Case Studies
May 12 | Presenter: Todd Havekost
Since it is likely that 1/3 to more than half of your total CPU cycles are spent waiting for data to be staged into level 1 processor cache, it is critical to understand and have visibility into this significant component of your CPU consumption.
This is not ivory tower theory… every main point in this presentation is backed up with real-life case studies from more than 70 sites across 8 countries.
And though these concepts have been presented before, the presentation continues to be enhanced with additional before-and-after data from sites quantifying the CPU reductions they have achieved through more effective utilization of processor cache.

6. The All-Flash datacenter: How come my I/O Response isn’t twice as fast?
May 20 | Presenter: John Baker
In IT, the term “Flash” is both ubiquitous and vague. The solid-state drive in your laptop, the new memory in your z15, your new all flash storage array – these all boast flash technology that promises to make everything faster.
Many datacenters have adopted flash technology and are observing that their I/O response times are not dramatically different. Why? John breaks down this relatively old invention to understand what it can – and cannot – do for your datacenter.

10. Getting to Know Your WebSphere for z/OS Workload
June 17 | Presenter: Dennis Moore
WebSphere Application Server is mission-critical for many businesses today. However, for many mainframe performance/capacity specialists, these workloads can be a bit of a mystery – a black box of resource consumption that is hard to get your arms around.
There are many areas of WebSphere that can leave even a seasoned z/OS performance specialist scratching their head. Knowing what you want to see and where to look is one hurdle to overcome, but even then, how do you access that data? And more importantly, how do you visualize it in a way that makes sense? This webinar will help you:
- Gain a better understanding of your WebSphere workload through SMF data
- Quickly see transaction rates, CPU/zIIP utilization and response times
- Spot trends, patterns and unusual conditions
Join us to learn how you can shine a light into this otherwise black box!

12. Does IBM’s Recent Tailoring of Tailored Fit Pricing Make It a Better Fit for You?
July 1 | Presenter: Cheryl Watson of Watson & Walker
Every IBM software pricing option has a set of customers that it will benefit. For the remaining customers, one of the other options might make more sense. IBM’s Tailored Fit Pricing option had some aspects that limited the set of customers that it was a good fit for. In this webinar, mainframe maven Cheryl Watson describes recent, unannounced, changes to TFP, and explains how those changes might alter your calculation about whether TFP is right for your company.

13. Is a Sub-Capacity CPC the Right Move for You?
July 8 | Presenter: Frank Kyne of Watson & Walker and Todd Havekost of IntelliMagic
Most installations tend to upgrade their CPCs to the equivalent model in the newer generation – for example, from a z13 710 to a z15 710. Accordingly, IBM’s capacity planning tools are designed to model upgrades to newer generations within the same speed range (7xx to 7xx, 5xx to 5xx, and so on). There are numerous stories of customers moving to a lower speed range (z13 7xx to z15 6xx, for example) and finding that the performance exceeds their expectations. But if the IBM tools are not intended to model such moves, how do you evaluate if such an upgrade would be right for your workloads? In this session, Frank and Todd will discuss the attributes that they use to evaluate such upgrades.

14. The Value of Automated z/OS Performance Change Detection
July 15 | Presenter: Todd Havekost
With all the complexity and workload variability present in today’s z/OS systems, it is important to have significant deviations of key metrics from their historical norms called to your attention. Built-in “change detection” functionality to automatically identify these deviations accompanied by intuitive capabilities to investigate the underlying causes provides another important step forward facilitating effective availability and performance management. This session will show how this capability complements health assessments using built-in instrumentation of z/OS best practices and will show real-life examples of how it can add value across several areas of the z/OS infrastructure, including CPU, CICS, Db2, CF, Disk replication, and batch jobs.

16. Your Datacenter Under TFP: The New Rules of Measurement
September 17 | Presenters: Cheryl Watson of Watson & Walker and John Baker of IntelliMagic
Tailored Fit Pricing is no longer an abstract concept as many data centers have adopted this new pricing model. For those that held back, recent enhancements from IBM have made TFP potentially more attractive. While TFP has the potential to greatly simplify software costs the Capacity Planner/Performance Analysts (CP/PA) needs to adjust many of their tried and true methods for tracking – and controlling – MSU consumption. Are you paying too much? Have your measuring tools and techniques adapted to these new rules? Join Cheryl Watson and John Baker as they dive into this critical subject. They’ve been known to have an opinion or two.

18. Transparency in z/OS Infrastructure Performance Analysis – The Benefits of Collaborative and Explainable Analytics
November 17 | Presenters: Dan Speer and Todd Havekost
Analyzing and optimizing performance and cost across the different z/OS infrastructure areas has led to many “silos” of expert knowledge which often create natural barriers to collaborative and quick problem-solving. It also makes it difficult for managers and LOB executives to easily understand the performance health and cost optimization status for their applications. This webinar will discuss the historical reasons why these silo barriers exist, their ramifications, how to achieve greater transparency and collaboration, and a roadmap to help break down the silos one application at a time.
