(Originally posted 2009-04-09.) So here’s yet another way of parsing the WLM XML Service Definition. This time it’s on z/OS, using DFSORT. Relatively recent features in DFSORT have made it easier to do useful things with XML. In this example I’ve made some attempt to make the output pretty – by creating a HTML table.Continue reading “Workload Manager Policy in XML Format – Part IV”

(Originally posted 2009-04-09.) It’s approaching conference season again – at least the UKCMG / European System z Conference portion of it. Bearing that in mind I want to share this article with you: “Professor Encourages Students to Pass Notes During Class — via Twitter”. It’s well worth reading the comments that follow the article. They’reContinue reading “Please DO Twitter In My Sessions”

(Originally posted 2009-04-08.) Here’s another way to process a WLM Service Definition – once you’ve got it into XML format. XSLT (XML Stylesheet Transformations if you prefer) is another technology that’s been around for a while. In simple terms you write another piece of XML (the stylesheet) that describes how to transform your original XMLContinue reading “Workload Manager Policy in XML Format – Part III”

(Originally posted 2009-04-07.) In Workload Manager Policy in XML Format – Part I I showed you how you can use PHP to extract Classification Rules information from the WLM Service Definition (once converted to XML format). This post gives an example of extracting a different set of information from the XML Service Definition, using javascriptContinue reading “Workload Manager Policy in XML Format – Part II”

(Originally posted 2009-04-06.) This isn't particularly new – but I'm guessing most people who work with WLM don't know about this… For some time now you've been able to download a java application that enables you to convert your WLM Service Definition to and from XML. Perhaps more importantly, the application provides a nice wayContinue reading “Workload Manager Policy in XML Format – Part I”

(Originally posted 2008-11-03.) Another 6 months on and another HackDay… Hackday6 was on 24 October – and being distracted by little things such as GSE Conference and an important customer situation I haven’t blogged about it yet. So, a little late, here goes… Many of you will know that RMF has a WebPortal for monitoringContinue reading “My HackDay 6 Project – Mashing Up RMF”

(Originally posted 2008-09-25.) With a couple of working days to go before the deadline I’ve completed my two presentations for Expo. As usual I’ve added some new stuff, based on new technologies and some situations I’ve encountered. And rather than throwing older stuff out I’ve moved most of it to backup foils. While I’m preparedContinue reading “System z Expo, Las Vegas, 13-17 October”

(Originally posted 2008-09-20.) Well, how many do you have? I’ll admit to 4 on my Windows XP Laptop (and 2 versions of 1 on my ASUS EEE PC, running Linux)… I firmly believe in having an “emergency browser”. At 0ne time that would have been Internet Explorer – for two reasons: To recover a brokenContinue reading “How Many Browsers Do You Have On Your Machine?”

(Originally posted 2008-09-19.) In recent releases RMF have put the machine serial number into both SMF Type 74 Subtype 4 (Coupling Facility Activity) and SMF Type 70 Subtype 1 (CPU Activity). Actually we get two fields in each case: Plant Number and Sequence Number, which you can put together as eg “51-12345”. Soon we’ll getContinue reading “Minor Good News On Coupling Facility Performance Reporting”

(Originally posted 2008-09-18.) Since I got back off vacation in L’Hérault in late August I’ve been working on adding z10 support to our CPU analysis code. It’s quite a substantial set of changes – and I don’t think I’m finished yet. But I’d like to share with you what I’ve learned so far. But firstContinue reading “System z10 CPU Instrumentation”
