• Guru Classic: More iSphere Goodies

  March 4, 2020 Susan Gantner

  This Guru Classic tip is my third in a series exploring the iSphere RDi plug-in. In this tip I’ll cover two additional ways in which iSphere expands the RDi toolset. There are a few details that I’ve updated in this new version of the tip due to updates in either RDi or the iSphere tool itself. Plus I have added an additional tip based on how I’ve seen one of these features utilized.

  Binding Directory Editor

  I’ve long been baffled at the lack of support in RDi for binding directories; it seems like something modern developers certainly use. In the …

• Guru Classic: Tuning SQL Environments On i

  March 4, 2020 Paul Tuohy

  Author’s Note: This article was originally published in November 2015. This was one of the first DB2 for i Services that I used in anger. I have used a lot since.

  One of the frustrating things about being a speaker at conferences is that when you want to attend another session with a topic that piques your interest, it invariably clashes with when you are speaking. But every now and again, the scheduling gods work in your favor. Such was the case when I spoke at the excellent International i-Power 2015 conference at Wyboston Lakes Executive Centre in the UK. …

• Guru Classic: Overlaid Packed Data In Data Structures

  March 4, 2020 Jon Paris

  When I re-read this tip while looking for a “Classic” candidate, I was reminded that the underlying issue it addresses, namely how data is actually stored in an RPG program, is one that many RPG programmers don’t really have a firm grip on. That alone made it a good candidate. But perhaps even more important is demonstrating this topic to the many new programmers coming onto the platform. Unlike those of us who started off with assembly languages, C, RPG, or COBOL, modern programmers trained in C#, Python, or PHP have never had any need to understand the mechanics of …

• Big Blue Raises IBM i Software Maintenance Fees Modestly

  March 2, 2020 Timothy Prickett Morgan

  Back in the AS/400 days when software was a much smaller part of the overall cost of a system, there were relatively frequent prices changes for both OS/400 and related systems software as well as for the software maintenance applied to OS/400 and those related systems programs.

  It has been a long time since IBM increased the license or IBM i Group Software Maintenance, or SWMA as we often call it as shorthand (pronounced Swammah). I can’t even remember the last time IBM i license prices were increased, but I know there was an attempt to raise SWMA prices …

• Boadway’s 25-Year Performance Shows No Let Up

  March 2, 2020 Alex Woodie

  Batch jobs running a little long? Throw some hardware at it. For as long as Mike Boadway can remember, that’s been the default response to dealing with most performance issues on the IBM i server. But when today’s fast Power9 processors and Flash drives fail to move the performance needle, maybe it’s worth reconsidering Boadway’s approach to tweaking the code and the data instead.

  As the CEO of MB Software & Consulting, Boadway makes his living off solving other people’s IBM i performance issues. Since founding the company in 1995, Boadway has used his proprietary software to deliver an …

• Guru: Practicing Safe Hex in RPG

  March 2, 2020 Jon Paris

  In this tip I’m going to address a question that arises regularly on RPG-oriented Internet lists, namely: “Is there an easy way to convert a character string to its hexadecimal equivalent?”

  One answer, of course, would be to write your own routine using lookup tables, but there is a far easier way. We can take advantage of the system’s hex MI APIs. These were originally surfaced for use by C and C++ but, thanks to the joys of ILE, can be used by any ILE language. Not only that, RPG’s prototyping support makes them really easy to use. In fact, …

• Please Take The 2020 State of Modernization Survey

  March 2, 2020 Timothy Prickett Morgan

  It wasn’t all that long ago that whatever information that we needed about the IBM midrange community had to come from Big Blue or once in a while one of the big IT market watchers like IDC and Gartner would get paid to think about our community and they would do what we usually considered a half-hearted job of it.

  In the past several years, a number of independent software vendors in the IBM i market have taken the bull by the horns and, with the help of publications like The Four Hundred, have gathered up vital intelligence through …

• IBM i PTF Guide, Volume 22, Number 9

  March 2, 2020 Doug Bidwell

  There is rarely a week that there isn’t something going on with PTF patches for the IBM i operating system, its integrated database, and the whole stack of software wrapping around that operating system. This would be one of those normal weeks, where there is nothing too crazy going on but there is stuff to pay attention to.

  We also had a leap year Saturday for the IBM i PTF Guide, which doesn’t happen very often. The Gregorian calendar has a 400-year – well, 146,097-day – cycle, and of these days, there are 97 days that correspond to February …

• New IBM Champions Reflect on Their Journeys

  February 26, 2020 Alex Woodie

  IBM has rolled out its new list of Champions for Power, and on the list are eight men from the IBM i community who have been named Champions for the first time. Among the honorees is the Four Hundred Guru himself, Ted Holt.

  Ted Holt: IT Jungle guru and senior software developer at Profound Logic

  

  Holt’s day job is working as a senior software developer for Profound Logic. But at night he becomes the IT Jungle’s Guru, dispensing IBM i code and snippets of hard-won wisdom as a senior technical editor of The Four Hundred. He also tweets from …

• Rocket Talks Up IBM i Biz in Wake of Restructuring

  February 26, 2020 Alex Woodie

  When Bain Equity bought a $2 billion stake in Rocket Software 16 months ago, it was largely viewed through a mainframe lens. Rocket was a mainframe software company, and Bain was investing in that mainframe business. But as the new general manager of the Power Systems Business Unit, Chris Wey, tells it, the company is getting ready to make some moves in the IBM i market, too.

  Wey joined Rocket Software at the beginning of the year, immediately following the 30-year-old company’s most recent restructuring following the Bain acquisition. Andy Youniss, who co-founded Rocket back in 1990 to capitalize on …
