(Originally posted 2009-04-26.) Here’s another “For Beginners” post to encourage people to just leap in and try it… Javascript is a language popularly used for such things as web pages with some programming in them (and that includes frameworks like dojo), building Firefox extensions, and the Adobe AIR (desktop) runtime. As it happens I’m prettyContinue reading “Javascript on z/OS For Beginners – Getting It To Run”

(Originally posted 2009-04-25.) In this post (and any others in a similar vein) I'm going to be displaying a great deal of ignorance – but I think I'm doing it in a good cause. I know a fair amount about things like Java, XML and C++ – but NOT on z/OS. So I'm determined toContinue reading “z/OS Unix System Services For Beginners – Java Hello World”

(Originally posted 2009-04-25.) Back in z/OS R.9 RMF Parallel Sysplex New Fields (in 2007) I mentioned a new field: R742MJOB (XCF Member Job Name.) At the time I had no real customer data so I could only espouse the HOPE that this field would be useful. (When I asked for it to be added toContinue reading “DB2 Data Sharing and XCF Job Name”

(Originally posted 2009-04-10.) To whoever (In the USA I think) Googled “what is REMOVECC” and got to this blog let me give you my thoughts on the matter. (And yes I know, it being a search, you might never come back to read this.) To understand REMOVECC you have to understand that the “CC” refersContinue reading “What is REMOVECC?”

(Originally posted 2009-04-10.) For whoever got to my blog with this Google search here’s how you sort data without a header: First you need to be using z/OS DFSORT Release 10 or to have applied the PTFs for UK90013 (July 2008). Second, the vehicle for doing this is ICETOOL rather than DFSORT itself. Use theContinue reading “DFSORT Sorting Without Sorting Header / Trailer Lines”

(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”
