Stream: CICS
Time: 16:45 - 17:45
When a CICS region goes Short On Storage you’ll want to know why – and what to do about it. And, being proactive, you’ll want to know which regions are at risk. Maybe it’s architecture, maybe it’s region size, maybe it’s an LPAR-wide problem. In this short presentation we discuss how to assess and manage CICS virtual storage. We start with an LPAR view, then go on to show an easy way to assess which CICS regions are at risk, then how to diagnose SOS conditions in individual regions. The approach is scalable and systematic, and can be pursued with commonly available data.

With 38 years of mainframe experience (about 45 of computers), Martin is widely known within the industry, having presented at many conferences and having authored a number of IBM Red Books on performance and other matters. He continues to develop System Analysis tools he uses every day in some of the most difficult Performance and related mainframe situations IBM customers encounter: He has a very wide range of experience of what enterprises do with their System z mainframes. Getting "low down and dirty" with instrumentation gives him a rare insight into what the data can do: He leads others - customers, IBMers, business partners, and other vendors - in getting the value out of this instrumentation. With that experience base he drives conversations with developers about enhancing instrumentation, as well as their products in general. But it's not all about the mainframe: He has a wide range of other technological interests. For example, he knows a lot about programming and how the web is constructed. A while back he started the Mainframe, Performance, Topics Podcast series with Marna Walle. Since 2020 Martin has been busy open sourcing a lot of tools he's written, some directly related to Mainframe Performance, others in the "authoring tools" category.
Todd Havekost has over 40 years of IT experience with a primary focus on system and subsystem performance across the IBM Z platform. He joined IntelliMagic in 2016 after experiencing first-hand as a customer the visibility IntelliMagic Vision provides into SMF data, and now spends his days helping customers derive great value from their own SMF data to improve availability and performance. Todd is a highly-regarded industry speaker and has given award winning presentations at events such as SHARE and CMG.
