Top 5 New IBM i Features to Check Out Now That Fall TRs Are GA

December 7, 2022 Alex Woodie

All of the new features that IBM unveiled earlier this fall with the Technology Refreshes for IBM i 7.4 and 7.5 (as well as another stealth “non-TR” TR for 7.3) are now generally available. Some of them shipped before December 2, but pretty much all of them are now GA. With so much enterprise computing goodness ready to download, what will you adopt first?

We know it’s not Christmas yet. But with so many new features, it can be hard to figure out what to do first. While everybody has their own computing priorities, we have our own ideas for …

IBM Welcomes COMMON Advisory Councils to Rochester

December 7, 2022 Alex Woodie

One of the hallmarks of a good company is listening to customers. A company may not do everything that its customers wish, but it must show that it’s listening to maintain the relationship. This dynamic was in play during an IBM i meeting that took place last month in Rochester, Minnesota, between IBM and the advisory councils for both COMMON North America and COMMON Europe.

The three-day meeting that took place November 14 through 16 involved a handful of members from the COMMON Americas Advisory Council (CAAC) as well as the COMMON Europe Advisory Council (CEAC). Both advisory councils had …

IBM Publishes Power10 Performance Optimize Guide

December 7, 2022 Alex Woodie

IBM i shops looking to squeeze the most performance out of their Power10 servers have a lot of options available at their disposal. IBM covers many, if not all, of them in its latest performance paper, titled “IBM Power10 performance optimization for IBM i,” which it released last week.

The Power10 is the most powerful processor IBM ever built. Compared to the Power9 processor, the Power10 delivers 20 percent to 30 percent higher performance per core. And with 25 percent more cores per socket, that means oodles of more processing power to do useful work.

At a system level, the …

Four Hundred Monitor, December 7

December 7, 2022 Jenny Thomas

We are back from the Thanksgiving break, but not for long. Just because there are only a few weeks remaining on the calendar doesn’t mean there is any shortage of news and happenings in and around our IBM i ecosystem.

Four Hundred Monitor will wrap up for the year next week, but before we go, let’s take a …

Surprise! There’s a Tech Refresh 13 For IBM i 7.3

December 5, 2022 Timothy Prickett Morgan

Well, we bet you were not expecting that. Or, based on past history, maybe you were. But when IBM put out the two Technology Refresh updates for IBM i 7.4 and IBM i 7.5 last Friday on December 2 as planned – that would be TR1 for the latter and TR7 for the former – the company also sneaked out an unofficial TR13 update to IBM i 7.3. With this Tech Refresh, IBM i 7.3 has many of the same updates that came to the two more current releases of IBM i.

If you look at the IBM i Technology …

Thoroughly Modern: A Swiss Army Knife For IBM i Developers

December 5, 2022 Robert Arce

Our strength as developers and programmers lies not only in the code we write, but also in the tools we choose to surround ourselves with. The right tools are often the determining factor in how productive, efficient and accurate we can be – especially when working with large applications that we didn’t even write.

Long gone are the days of just managing a handful of programs, technologies, languages or databases, and relying on tribal knowledge to make critical business decisions isn’t just risky, it’s irresponsible. Especially when more and more experienced IBM i (AS/400) developers are changing jobs or retiring …

Finding IBM i’s Place In Data Fabrics And Data Meshes

December 5, 2022 Alex Woodie

The commercialization of the Internet kicked off an unpredictable series of developments in the computing world. One of those is the proliferation of Web applications, each with its own data silo, bringing chaos to data management and data governance. Application architects are now seeking to tame that data chaos through novel infrastructure architectures, including the data mesh and the data fabric.

While the lure of digital transformation gives companies hope that they, too, can benefit from breakthroughs in analytics, machine learning, and IoT, the data at most companies is in such a state of mess that in most cases it’s …

SOAP Web Services Fail After WebSphere Liberty Patched

December 5, 2022 Timothy Prickett Morgan

If you had not yet gotten around to putting the October 2022 HTTP Group PTF patches for the WebSphere Liberty web application server on your IBM i system, that may turn out to be a fortunate thing. There is something wonky about SOAP web services running in conjunction with Integrated Web Services (IWS v2.6) and Integrated Application Server (IAS v8.5) middleware on the IBM i platform that is causing SOAP fault errors.

This error is documented here by IBM, and the techies that we know are trying to figure out the full extent of the issue. Doug Bidwell, our …
