The Mainframe is still strategic and will exist for a long time to come …

The projection of the Mainframe in the IS evolution roadmaps requires the implementation of a modernization and optimization strategy to meet the following challenges:

• Visible costs in the ISD budget and increasing due to the opening of the Mainframe (APIzation) which generates additional demands on the Mainframe
• A complex IBM billing model that requires expertise and constant effort to control it
• Less and less mastered treatments and applications with the gradual departure of the knowledgers (skilled people)

Take advantage of Mainframe resource analysis to improve performance and control costs:

• Obtain relevant information on the specifics of your production environment thanks to a real-time analysis platform
• Improve your understanding of resource usage, quickly identify a problem to instantly adapt configuration and capping
• Reduce costs by optimizing MSU consumption by automatically redistributing available resources in real time

Brian Hoare has seen the z platform grow from OS/390 to today’s z/OS. He may speak with a “strange accent” and has introduced new solutions into the USA and worked with several startups. He has presented at local/annual CMG’s, Share and many other conferences discussing cost reduction (IBM/MLC), performance and is now his focused on analytical data on “z”.  Mainframe analytics are his latest passion, especially as Z is the richest source of data there is. So why not use the richest source of data we have for helping to run the business?

Mainframe performance is not only limited to the amount of available resources but strongly depends on how well you organize the work running on your machine. The Workload Manager helps you organize your workloads depending on business priorities while Hardware Instrumentation Services (HIS) give you insights on the performance of your current LPAR configuration. Understanding how to analyze these components is a gold mine for performance optimization projects.

The site crash was and still is their best sales day, ever. The platform failing over caused people to keep trying and trying to get through. The site failing over made them more desirable. They didn’t just keep trying for 5-10 mins and give up. They were trying all day. People had a fear of missing out…

Concurrent User is one of the key performance metrics in a system. Many performance issues that can only be exposed under load are related to the increased number of concurrent users. In the context of load test, we often hear phrases such as “test the system under x concurrent users”. This is a common misunderstanding of the term. In most cases, Concurrent User is a Random Variable. We propose an analytical alternative to the classic queuing theory for estimating Concurrent User. This model helps us determine whether the simulated workload is a proper representation of the expected production scenario.

How to be sure a cloud object’s (e.g, AWS EC2, RDS or EBS) workload fits the rightsized resources (Compute, RAM, IO/s and Network traffic)? It is very difficult to do using raw system performance data from monitoring tools. The best way to do that is using a weekly workload profile, which is a graphical visualization in form of MASF IT-Control chart. This chart shows the stability of the workload, reveals the anomalies happened recently, such as run-away, memory leaks or specifically important for cloud objects, the unusual number of hours the object is down all compared with the usual weekly pattern.

This presentation will describe how to build, read, and use workload profiles using real data examples and demonstrates how cloud capacity scaling could be verified.

As many Z Systems specialists approach retirement, the issue of their successors arises. While younger analysts may find working with other platforms more appealing, several facets of Z Systems may be shown to convince them of their stability, reliability, and career security.

Not all performance topics and recommendations simply cut and dry. Many are controversial. These are the recommendations that tend to generate discussion amongst peers, need careful consideration, or may depend on which ‘performance camp’ you belong to. During this presentation, we will explore some of these topics.
