Most mainframe sites are regularly on the lookout for potential ways to reduce expenses. The adoption by many sites of TFP-based software license models where all CPU is chargeable has made this an even higher priority.
This webinar is designed to expand your awareness of ways sites have reduced CPU and expenses so that you can identify ones potentially applicable in your environment. Opportunities explored will include those applicable to individual address spaces or jobs as well as others with the potential to provide benefits broadly applicable across the infrastructure.
Attendees can expect to learn from successes realized in other sites that will expand the “menu” of cost savings ideas they can explore.
Presenter: Todd Havekost
The mainframe produces a set of metrics far superior to any other platform. Unfortunately, there are significant barriers to unleashing the learning value of this SMF data.

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.

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.

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:
Join us to learn how you can shine a light into this otherwise black box!

The z14 and z15 support a completely new I/O method called zHyperLink. This is easily the most substantial I/O announcement from IBM since the introduction of FICON. We all know that the best I/O is no I/O but every record won’t fit in your buffer pools, so I/O is a fact of life. What about more cache or flash drives? The many options to accelerate your speed on the I/O highway can make you lose your mind – come check out the fast lane!

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.

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.

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.

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.

2020 will undoubtedly go down as a year to remember for each and every one of us. The way that every business has adapted to the changes shows resiliency and creative professionalism in positive ways. One thing that has not changed is the need to ensure that our infrastructure and applications can handle peak loads at any time. This webinar will demonstrate how to quantify risk in the z/OS infrastructure to ensure better availability in peak periods, and how intelligent navigation through the RMF/SMF data can accelerate problem resolution times and display newly supported SMF data.

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.

MQ Statistics and Accounting SMF data provides extremely useful insights into MQ management and operation. Unfortunately, extracting those insights from the SMF 115 and SMF 116 record types is challenging – and raw data pulls lack context or accessibility.
With proper access to the insights derived from this data, analysts can optimize their z/OS MQ configurations and activity more effectively and efficiently and have better visibility and control over their environment. This webinar demonstrates how to overcome these common challenges and offers a guide to analysts responsible for and working with MQ environments.

IBM’s introduction and active promotion of the Software Consumption (SC) solution within Tailored Fit Pricing (TFP) brings with it a fundamental change in how sites will approach managing and reducing software expense.
Instead of being driven only by CPU usage during the monthly peak four-hour interval, under the SC model, software is charged based on the total CPU consumption for the entire month (at a much lower unit price). This new SC model brings with it a new set of challenges for managing an environment and at the same time potentially significant opportunities to reduce software expense over the long term.

Duration. Seems simple enough: how long do I give a transaction to get done? The reality is somewhat more complex. Firstly, the duration is not wall-clock time, it’s weighted Service Units. And what are your ‘weights’ (coefficients) anyway?
Multiple periods are one of the most powerful – and dangerous – tools in the performance analyst’s arsenal. They can ensure critical work gets done and runaway work can’t take over. This webinar provides a timely update to setting up or reviewing this critical area.

As of z/OS 2.5, WLM coefficient settings were removed; IBM made a good move in sunsetting an obsolete set of variables. I/O priority should follow. WLM I/O Priority has been around for a long time and is in use at many data centers. A recent survey revealed many sites are not even clear on what the setting does. While the default is ‘off’ the recommendation in the WLM Planning manual is ‘on’. In this presentation, we will demonstrate why this option should be turned off and perhaps removed entirely like the coefficients.
