So long, and thanks for all the fish

My final blog, ever!

I’ve taken the title of this blog from the fourth book of the Hitchhiker's Guide to the Galaxy trilogy (which actually has six books) written by Douglas Adams. It originally came from The Hitchhiker's Guide to the Galaxy where dolphins used the phrase as they left Earth just before it was destroyed. People use it as a way of saying goodbye and acknowledging that their previous experience had been positive.

I am retiring at the end of this month, and this is my final blog. And, I have rather enjoyed myself.

I started my working life as a science and maths teacher, and I was instrumental in introducing IT into the secondary school that I taught in. My head of department and myself did a training course on how to teach IT to the young people at school. While we were training, I was offered the chance to go into industry to see what it was like in order to tell the youngsters about it. I spent three weeks at an IT bureau called Scicon. They offered me a job!

Scicon had an association with BP. It had Univac computers originally, and I was working as an operator. I was paid more than I had been as a teacher, and I didn’t spend every evening marking books, and every holiday planning for next term. The arrival of an IBM mainframe caused quite a stir. It didn’t work in the same way as the Univac machines. I learned how to use it and to write JCL. And I became the one-man support desk for the IBM machines (they soon got a newer second one). The downside was that I was on call 24 hours a day, seven days a week.

Combining my teaching experience with my mainframe experience seemed an obvious next step. I got a job as a lecturer with a company called Protocol, which offered operator training for MVS, VM, and VSE sites. It involved travelling all over the UK and abroad (Europe and the Middle East). I was soon a senior lecturer and writing the training courses that I was delivering. I had young children by that time, and coming home at a sensible time in the evening seemed preferable, so I left and joined Xephon.

Xephon was a much more professional organization, with much higher standards. It offered seminars and publications. I found myself editing their new idea of Update journals, containing code written by mainframers for mainframers. It was the days before the Internet and it was a great way to share information. I also produced some surveys, such as The Help Desk in Action, and I chaired some of the webinars. Over time, I edited most of the Update journals for at least part of their lifespan. I also wrote three books, two on VM and one about automated systems operations.

Xephon was sold, and I set up iTech-Ed Ltd in 2004. I continued producing and editing the Update journals, which were then published by US-based Software Diversified Services (SDS). I also did some other work. At the end of 2007, the Update journals were stopped. By then, people were sharing code on the Internet and so sales, which has peaked in the 1990s, were much diminished. I started working on the Arcati Mainframe Yearbook, and I also launched the Virtual IMS user group at the end of that year. By the time I sold those assets to Planet Mainframe, there was also a Virtual CICS user group and a Virtual Db2 user group. I became an IBM Champion in 2009, and I am still a champion in 2025. After attending the Guide Share Europe (GSE) UK regional conference for many years, I started speaking at it in 2021. Last year, I spoke about How to create Artificial Generalized Intelligence.

In 2008 I started training as a solution-focused hypnotherapist, and I’ve helped people using hypnotherapy since 2009. I also trained as a hypnotherapy supervisor in 2012. At the start of 2012 I joined the executive of the AfSFH (association for solution-focused hypnotherapy). I completed a number of other relevant training courses. I also gave a number of CPDs (continuous professional development) training courses. In 2022 I became a Fellow of the AfSFH, one of the first four people to receive that distinction. I wrote 12 books, and any number of articles and blogs. In 2021, I started the Solutions podcasts with Cathy Eland, and a book containing four years’ worth of scripts is now available.

Worryingly, the school I taught at closed not long after I left. Scicon closed after I left. Protocol grew hugely in terms of staff numbers after I left and then collapsed. Xephon closed while I was still there. And now, my company, iTech-Ed Ltd is closing.

I have written well over a thousand blogs and articles over the years – not all of them published here. I’ve written for Planet Mainframe and TechChannel, and other sites. And I’ve written articles that have been published under other people’s names too.

In terms of legacy, the Arcati Mainframe Yearbook (now called the Arcati Mainframe Navigator) and the three user groups are still going under the Planet Mainframe banner. Some of the CPDs I created are now owned by other organizations and can continue being delivered. My books are available for people to buy. And the people I helped with solution-focused hypnotherapy are hopefully still benefitting from it.

Thank you to everyone who has helped and supported me through the different stages of my working life.

I do have plans for my retirement, although a lot of my time will be spent with grandchildren – which is great.

Welcome to the z17

Last Tuesday, IBM finally unveiled its much-hyped z17 mainframe – and they had much to be excited about with this new mainframe. Like everything else these days, it comes with AI – or, more accurately, it comes with chips designed for AI. The z17s become generally available on the 18 June, with the IBM Spyre Accelerator to follow in the final quarter of 2025. Let’s take a look at the details of the new machine.

We first heard about IBM Telum II chip and the Spyre Accelerator back at the start of September last year, when it was unveiled at the Hot Chips 2024 conference. They told us then that the chips are designed to support a broader, larger set of models with what’s called ensemble AI method use cases. Using ensemble AI leverages the strength of multiple AI models to improve overall performance and accuracy of a prediction as compared to individual models.

The Telum II comes with an on-chip AI accelerator, as you’d expect, so the z17 has the ability to process 50 percent more AI inference operations per day than the z16. In fact, it can perform over 450 billion inferencing operations daily with one millisecond response times. There’s also been a 40 percent growth in cache, which goes some way towards making this possible.

The IBM Spyre Accelerator comes on a PCIe card, and provides additional AI compute capabilities, creating environments to support multi-model methods of AI. The Spyre Accelerator is specially engineered to bring generative AI capabilities to the mainframe including running assistants, leveraging enterprise data contained in the system.

Among the AI assistants and AI agents that are supported are IBM watsonx Code Assistant for Z and IBM watsonx Assistant for Z. These enhance developer and IT operations productivity. For the first time, watsonx Assistant for Z will be integrated with Z Operations Unite to provide AI chat-based incident detection and resolution using live systems data. IBM Z Operations Unite is a solution designed to unify key performance metrics and logs using OpenTelemetry format. This is expected to accelerate the time to detect anomalies, isolate the impact of potential incidents, and reduce the resolution time.

Ross Mauri, general manager of IBM Z and LinuxONE, IBM said: “With z17, we're bringing AI to the core of the enterprise with the software, processing power, and storage to make AI operational quickly. Additionally, organizations can put their vast, untapped stores of enterprise data to work with AI in a secured, cost-effective way.”

In, what might be called, a teaser trailer, IBM previewed a new version of its z/OS operating system (V 3.2), which will be released in the third quarter of 2025. z/OS 3.2 will support hardware-accelerated AI capabilities across the system and operational AI insights for system management capabilities. What’s more, z/OS 3.2 will support modern data access methods, NoSQL databases, and hybrid cloud data processing, helping AI software tap into a broader set of enterprise data and derive predictive business insights.

Of course, AI isn’t the only thing on the minds of potential customers of the z17. The big issue for many mainframe-using organizations is security. IBM has addressed that worry in the z17 announcement.

The z17 also includes IBM Vault, which will help to standardize secrets management across hybrid cloud, leveraging technology from HashiCorp, which were announced last month. IBM Vault uses identity-based security to authenticate and authorize access to secrets, certificates, keys, tokens, and other sensitive data. With the addition of IBM Vault, clients can have a single solution to help protect critical workloads by managing the entire secrets lifecycle across their full IT estate.

IBM also intends to deliver new capabilities for discovering and classifying sensitive data on the platform. This would tap into Telum II and utilize natural language processing so that mission-critical data can be identified and protected. In addition, IBM Threat Detection for z/OS, a new AI-driven security solution, is designed to detect and identify potentially malicious anomalies that might be the result of a cyber-attack.

IBM Support for z17 helps clients optimize their environments for peak performance to address risk and disruptions for mission-critical operations. IBM's AI processes streamline incident remediation and help improve case resolution time, built on IBM watsonx, now support IBM Z systems.

IBM says that the tenth generation of IBM Storage DS8000 is designed to harness the full power of IBM z17, providing organizations access to critical workloads, consistent and optimized data performance, and a modular architecture to adopt the latest IBM research-backed technologies to fuel business growth while monetizing data.

The z16 has been selling well for IBM over the past couple of years, and investors seem to anticipate much the same for the z17, with a 2% rise in IBM's stock following the announcement.

It certainly seems like IBM is moving in the right direction with this latest mainframe announcement.
