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”
SRB And SMF
I’ve just had my first brush with SMF from z15’s System Recovery Boost (SRB). (Don’t blame me for the reuse of “SRB”.) 🙂 The point of this post is to share what I’ve discerned when processing this SMF data. System Recovery Boost To keep the explanation of what it is short, I’ll say there areContinue reading “SRB And SMF”
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?”
Mainframe Performance Topics Podcast Episode 29 “Hello Trello”
This was a fun episode to make, not least because it featured as a guest Miroslava Barahona Rossi. She’s one of my mentees from Brasil and she’s very good. We made it over a period of a few weeks, fitting around unusually busy “day job” schedules for Marna and I. And this one is oneContinue reading “Mainframe Performance Topics Podcast Episode 29 “Hello Trello””
Mainframe Performance Topics Podcast Episode 28 “The Preview That We Do Anew”
(Originally posted 2 March, 2021.) It’s unusual for us to publish a podcast episode with a specific deadline in mind. But we thought the z/OS 2.5 Preview announcement was something we could contribute to. So, here we are. I also wanted to talk about some Open Source projects I’ve been contributing to. So that’s inContinue reading “Mainframe Performance Topics Podcast Episode 28 “The Preview That We Do Anew””
Mainframe Performance Topics Podcast Episode 26 “Sounding Board”
In Episode 25 I said it had been a long time since we had recorded anything. That was true for Episode 25, but it certainly wasn’t true for Episode 26. What is true is that it’s taken us a long time from start to finish on this episode, and ever so much has happened alongContinue reading “Mainframe Performance Topics Podcast Episode 26 “Sounding Board””
Mainframe Performance Topics Podcast Episode 25 “Flit For Purpose”
It’s been a long time since Marna and I recorded anything. So long in fact that I’d forgotten how to use my favoured audio editor Ferrite on iOS. But it soon came back to me. Indeed the app has moved on somewhat since I last used it – in a number of good ways. So,Continue reading “Mainframe Performance Topics Podcast Episode 25 “Flit For Purpose””
