In Automating Microsoft Excel I wrote about some basic manipulation of graphs in Excel for Mac OS, using AppleScript. I’m writing about it again because of the paucity of examples on the web. Here is an example that shows how to do a number of things in that vein. tell application "Microsoft Excel" set cContinue reading “More AppleScript And Excel”

Relating Parked Time To Cores
In Drawers And More I mentioned Parking with the words One day I’ll be able to colour VL’s according to whether they are parked or not – or rather fractions of the interval they’re parked. That’s a not very difficult fix for the python code. Well, that proved as simple as I thought. So, alongContinue reading “Relating Parked Time To Cores”
Drawers And More
Late last year I wrote a blog post: Drawers, Of Course. I’ll admit I’d half forgotten about it. Now that a few months have passed it’s time to write about at least part of it again. So why write about it again now? I’ve so much more experience with the instrumentation I described in thatContinue reading “Drawers And More”
Drawers, Of Course
This post is about processor drawers and how the topic might influence your LPAR design. Introduction Once upon a time drawers and books were very simple. If you wanted a certain number of processors – whether GCP, zIIP, zAAP, IFL, or ICF – that determined the number of drawers you had. (I’m still hearing peopleContinue reading “Drawers, Of Course”
Mainframe Performance Topics Podcast Episode 34 “Homeward Bound”
We started planning this one quite a while ago. Thankfully our topics tend to be evergreen – in that they’re still topical for quite a while. In that vein I know we are gaining new listeners and they aren’t all starting with the latest episode. Anyway, our schedules have been their usual hectic selves –Continue reading “Mainframe Performance Topics Podcast Episode 34 “Homeward Bound””
Reduced To A Single Tap
(This is not a post about plumbing.) 😀 It’s been a while since I last wrote about personal automation. And in Stickiness I talked about what makes automations stick for me. This post is about experiments with RFID detection and automation. These actually turned into something I use daily when I’m at home. Hobbyist DigitalContinue reading “Reduced To A Single Tap”
Bursty Batch – Small Reprise
In Bursty Batch I talked about how some customers have large amounts of batch work coming in all at once, and how a new WLM function in z/OS 3.1 might be handy in catering for it. And it subsequently occurred to me there is a cheap-to-collect and therefore almost universal method of assessing how burstyContinue reading “Bursty Batch – Small Reprise”
In My Estimation
This post is about Coupling Facility sizing – particularly when you don’t have one to start with. And particularly CPU. (Memory is reasonably catered for with CFSizer – whether over the web or now in z/OSMF for z/OS 3.1.) And the reason I’m writing about this is because I was recently asked to help sizeContinue reading “In My Estimation”
Bursty Batch
Bursty batch is quite common. For example, a customer I’m dealing with right now kicks off a burst of batch at 7PM and another burst at 10PM. I doubt that customer is reading this blog post. Another customer has a burst of batch kicking off at 2AM. They probably will read this post. But theirContinue reading “Bursty Batch”
Tips For Debugging A DFSORT E15 Exit
I suppose I’d better tell you what an E15 exit is – else you might not read the rest of the post. 😀 DFSORT (and its competitor) allow you to send records to an exit routine. This happens as the very first thing for processing an individual record. This routine is called an “E15 routine”.Continue reading “Tips For Debugging A DFSORT E15 Exit”
