• How GraphQL Can Improve IBM i APIs

  March 9, 2020 Alex Woodie

  IBM i shops are embracing APIs as a method for accessing data and programs, just like the wider IT world. As RESTful Web services overtook SOAP-based ones in popularity, IBM i shops moved with them. Now a new approach to Web services, dubbed GraphQL, is gaining traction in the wider IT world, and leading IBM i developers are right there again.

  GraphQL, if you’re not familiar, is a relatively new language and runtime for exposing and consuming APIs. The software, which was originally developed in 2015 by Facebook to streamline delivery of content in complex environments, essentially provides an abstraction …

• Thoroughly Modern: Giving IBM i Developers A Helping Hand

  March 9, 2020 Timothy Prickett Morgan

  (Sponsored Content) The good thing about the Moore’s Law improvements in compute, storage, and networking capacity is that the cost of a complete IT system more accurately reflects where the real value of that system was always really derived.

  In decades gone by, the AS/400 hardware cost represented somewhere on the order of 85 percent of the cost of a server and its storage and the OS/400 systems software accounted for the remaining 15 percent or so. Over time, the hardware costs have dropped to about a third of the overall system cost as systems have also gotten …

• Guru: In Pursuit Of Reasonable Data

  March 9, 2020 Ted Holt

  My awareness of the indifference of computers toward the reasonableness of data dawned when I enrolled in the university. The band director told me to sign up for band and jazz band for zero semester hours. He said the stupid computer wouldn’t know that no one takes a course for zero hours, wouldn’t flag me to obtain permission from the dean to carry an overload, yet would grant me the credit. He was right.

  Love ‘em or hate ‘em, we live with them, we learn to get around them when they limit us, and we deal with them when they …

• As I See It: In the Shadow of The West Wing

  March 9, 2020 Victor Rozek

  Twenty years ago, I developed an addiction. Not to one of the usual recreational substances, but to Aaron Sorkin’s writing. The West Wing was like no other show I had ever seen. It had gravitas. It explored issues of significance. The dialogue was crisp and quick. The characters had range, from funny and wise, to playful and profound. For the first time since I began watching television, I didn’t want to miss a single word.

  It aired at a difficult time for the country. The Bush administration was in the process of orchestrating two major wars, the housing bubble, and …

• Big Blue Cuts Deals On Entry Power Systems Iron

  March 9, 2020 Timothy Prickett Morgan

  With no new Power processors on the immediate horizon, except a kicker Power9’ that is aimed at supercomputer systems providing a testbed for future high bandwidth main memory technology that will debut with the Power10 chips in 2021, IBM has to do something to try to move some iron. Price cuts are always a good incentive.

  And so, we see in announcement letter ZAEP0091B, which was quietly updated on March 5, when it came to our attention, after being announced on January 24, when we did not see in the IBM online announcement feed (because it wasn’t there, not …

• 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 …
