(Originally posted 2013-06-24.) I’ve been fortunate enough to speak at two conferences in the past month: UKCMG Annual Conference – in London in May System z Technical University – just outside Munich in June I presented three different sets of material, with very little overlap: Time For Dime Life And Times Of An Address SpaceContinue reading “Recent Conference Presentations”

(Originally posted 2013-06-07.) I like REXX but sometimes it leaves a little to be desired. This post is about a technique for dealing with some of the issues. I present it in the hope some of you will find it worth building on, or using directly. Note: I’m talking about Classic REXX and not OpenContinue reading “Dragging REXX Into The 21st Century?”

(Originally posted 2013-06-01.) Over the years I’ve written emails with data collection requirements dozens of times, with varying degrees of clarity. It would be better, wouldn’t it, to write it once. I don’t think I can get out of the business of writing such emails entirely but here’s a goodly chunk of it. Another thingContinue reading “Data Collection Requirements”

(Originally posted 2013-05-26.) I have REXX code that can be called directly by TSO (in DD SYSTSIN data) or else by another REXX function. I want it to behave differently in each case: If called directly from TSO I want it to print something. If called from another function I want it to return someContinue reading “REXX That’s Sensitive To Where It’s Called From”

(Originally posted 2013-05-22.) It’s possible I’ve written something about this before: My blog is so extensive now it’s hard to find out exactly what I’ve written about (and I’m going to have to do something about that). I say “written something” because I know for sure I haven’t written about the SMF record field IContinue reading “Discovering Report Class / Service Class Correspondences”

(Originally posted 2013-05-20.) A customer asked me to examine two WLM service definition snapshots taken on adjacent days – and discern any differences. This is not a challenge I’ve been set before – and so I expect it’s pretty rare. But, thinking about it, I reckon it could be quite useful. So they sent meContinue reading “Playing Spot The Difference With WLM Service Definitions”

(Originally posted 2013-05-02.) In October Frank Kyne and I expect to run a residency in Poughkeepsie. You can find the announcement here. The residency builds on the ideas presented here and three subsequent posts. I revisited a specific part of it in Cloning Fan-In. So what are we going to do? For a start we’reContinue reading “New Batch Residency”

(Originally posted 2013-05-01.) This is the second part, following on from Part 1. Importance Versus Velocity After drawing out the hierarchy you have to set actual goals – whether velocity or some form of response time. And you have to set importances. The importances should now be easy as they flow from the hierarchy. IRLMContinue reading “Analysing A WLM Policy – Part 2”

(Originally posted 2013-05-01.) This post started out with the title “Insufficient Nosiness?” I think most of mine do. 🙂 And if they do they should be subtitled “What You Don’t Know Can Still Harm You”. 🙂 Since then its scope’s expanded somewhat and now it’s in two parts, the second part being here. A lotContinue reading “Analysing A WLM Policy – Part 1”

(Originally posted 2013-04-08.) You wouldn’t put all your eggs in one basket, CICSwise, would you? A naive reading of the CICS TS 5.1 announcement materials might lead you to suppose you could. This post is about thinking about your CICS region portfolio in the light of this announcement. While every CICS release introduces capabilities thatContinue reading “How Many Eggs In Which Baskets?”
