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””

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”

Mainframe Performance Topics Podcast Episode 33 “These Boots Were Made”

I hope you can tell that Marna and I had a lot of fun making this episode. I can’t recall which of us came up with the cultural reference. But it sort of developed – until the aftershow was sort of inevitable. Anyhow here are the show notes for Episode 33. The podcast series isContinue reading “Mainframe Performance Topics Podcast Episode 33 “These Boots Were Made””

Mainframe Performance Topics Podcast Episode 32 “Scott Free”

Episode 32 was, as always a slow train coming. I think it’s a fun one – as well as being informative. It was really good to have Scott back, and we recorded in the Poughkeepsie studio, just after SHARE Atlanta, March 2023. Talking of which, the aftershow relates to SHARE. It’s a classic example ofContinue reading “Mainframe Performance Topics Podcast Episode 32 “Scott Free””

Mainframe Performance Topics Podcast Episode 31 “Take It To The Macs”

This is the first blog post I’ve written on my new work MacBook Pro. While it’s been a lot of work moving over it’s a better place as it’s an Apple Silicon M1 Max machine with lots of memory and disk space. That’s nice, but what’s the relevance to podcasting? Well, it’s very warm hereContinue reading “Mainframe Performance Topics Podcast Episode 31 “Take It To The Macs””

Mainframe Performance Topics Podcast Episode 30 “Choices Choices”

It’s been a mighty long time since Marna and I got a podcast episode out – and actually we started planning this episode long ago. It’s finding good times to record that does it to us, as planning can be a bit more asynchronous. Hopefully this delay has enabled some of you to catch upContinue reading “Mainframe Performance Topics Podcast Episode 30 “Choices Choices””

Really Starting Something

This post is about gleaning start and stop information from SMF – which, to some extent, is not a conventional purpose. But why do we care about when IPLs happen? Likewise middleware starts and stops? Or any other starts and stops? I think, if you’ll pardon the pun, we should stop and think about this.Continue reading “Really Starting Something”

What’s The Use?

It’s “Sun Up” on Conference Season – and I have a new presentation. It’s called “What’s The Use?” And it’s a collaboration with Scott Ballentine of z/OS Development. It’s very much a “field guy meets product developer” sort of thing. It emerged from a conversation on IBM’s internal Slack system. The idea is very simple:Continue reading “What’s The Use?”

Three Billboards?

You could consider presentations as advertising – either for what you’ve done or for what something can do. Generally my presentations are in the category of “Public Service Announcement”. Which rather combines the two: What I’ve found I can do – that you might want to replicate. What I’ve found a product can do –Continue reading “Three Billboards?”
