• Thoroughly Modern: Why You Need An IT Strategy And Roadmap

  July 14, 2020 Timothy Prickett Morgan

  What makes a modernization project successful? Is it the right software and tools? Having the right people on the job? Completing the project on time and on budget? Some might argue that all of the above contribute to the overall success of these initiatives. But the experts at Fresche will tell you that building a comprehensive strategy and roadmap is the most important part. It’s the secret sauce that ensures that the project provides business value and that requirements are mapped out before you start. After all, failing to plan is planning to fail.

  Businesses today are facing increasing pressure …

• Guru: The Case for Mixed-Case Procedure Names

  July 14, 2020 Paul Tuohy

  Using mixed case makes source code easier to read and easier to debug. I programmed in all upper case for many, many years, so I don’t recoil in horror when I see something in all uppercase. However, it’s a bit more difficult for developers who aren’t quite as long in the tooth as I am. To them, all uppercase is pretty abhorrent and bad (and I don’t mean bad as in good).

  There is a potential case issue with subprocedure names: there are at least three places on the system where the system shows subprocedure names in uppercase, regardless of …

• The Path Truly Opens To Alternate Power CPUs, But Is It Enough?

  July 14, 2020 Timothy Prickett Morgan

  If you have a few tens of millions of dollars to spare and you want to set up a foundry partnership with either Globalfoundries for 14 nanometer chip making technologies or with Samsung for 7 nanometer technologies and then create your own Power processor, things just got a little bit easier. Big Blue has open sourced one of its Power cores through the OpenPower foundation and now anybody and everybody can grab it and design a new central processing unit around that core.

  Don’t get too excited, but get a little excited. Let me explain.

  We still believe in the …

• IBM i PTF Guide, Volume 22, Number 27

  July 14, 2020 Doug Bidwell

  Welcome to the second half of 2020 after a brief holiday hiatus from The Four Hundred and therefore the IBM i PTF Guide.

  There is another new HIPER for the Virtual I/O Server, or VIOS, which again we know all of you IBM i shops love dearly. The HIPER is IJ25390, and it is for slow TCP performance with the Virtual Ethernet adapter and large send. Here is some more on that LSO – short for large send offload – and specifically a link that explains it better than we did two weeks ago, plus another link to a …

• The Power S812 Gets Yet Another Stay Of Execution

  July 6, 2020 Timothy Prickett Morgan

  The Power S812 entry server, which is based on the Power8 processor and which has no analog in the Power9-based Power Systems lineup, has received yet another reprieve from being removed from the Big Blue product catalog. It is a wonder why IBM doesn’t just say it will sell this Lazarus machine indefinitely and get it over with, to be honest.

  The Power S812, particularly the “Mini” variant that IBM announced on Valentine’s Day in 2017, are the skinniest – in terms of processing and memory capacity – of the Power Systems line that supports the IBM i operating …

• Tapping The Sky For Disaster Recovery

  July 6, 2020 Timothy Prickett Morgan

  The killer app for IBM i in the cloud, at least for the next several years, is very likely going to be disaster recovery and high availability. Not just because it is so much less expensive to provide these vital infrastructure services on the cloud than it is on premises, but because so many people still need DR and HA but cannot afford it.

  The cloud is changing that, and a partnership between Skytap, the upstart provider of IBM i server instances in the cloud, and Maxava, the now established but once upstart provider of HA and DR software …

• Guru: RDi V9.6, Part 9 – RDi Helps with Refactoring Code into Procedures

  July 6, 2020 Susan Gantner

  I’m guessing that you have some RPG code in your shop that’s desperately in need of some refactoring. I have yet to visit an RPG one that wasn’t in that position. If by chance you don’t know what I mean by “refactoring” or why you may need it, I highly recommend that you read Ted Holt’s excellent series of Guru tips on refactoring RPG. I’ve included links to those tips in the Related Stories section below.

  I was inspired to go back and review the entire series after I attended Ted’s session Refactoring RPG: What, Why & How at an …

• Wire IoT Up To IBM i With Node-RED

  July 6, 2020 Alex Woodie

  The Internet of Things (IoT) brings a new way to think about our digital world. From sensors on a manufacturing line to Twitter messages from the other side of the world, the IoT brings it all together. And with Node-RED, a low-code framework that is available on IBM i, wiring up these data flows into useful applications is surprisingly easy.

  Created by IBM, Node-RED is a Node.JS-based framework for developing event-driven data applications, or “flows,” that deliver a data payload in the form of the JavaScript Object Notation (JSON) data standard, from a source to a destination. Node-RED flows …

• IBM i PTF Guide, Volume 22, Number 26

  July 6, 2020 Doug Bidwell

  Well, we made it through half of 2020, and that is something of a miracle. Let’s hope the second half is not so dramatic. The odds are not favoring that at the moment, but hope springs eternal and that is how we have made it through the past 15,000 years of pre-history to today, if you think about it. It’s helpful to take the long view at critical times.

  As far as PTFs go, there is a new HIPER for the Virtual I/O Server, or VIOS, which we know all you IBM i shops love. The HIPER is IJ25390, and …

• You’re Only As Old As The Applications You Feel

  June 24, 2020 Timothy Prickett Morgan

  You didn’t actually think that we would have forgotten that Sunday, June 21^st, was the 32^nd birthday of the Application System/400, did you? Of course we didn’t forget.

  It was also Father’s Day and the first day of summer, and to be perfectly frank (Soltis), I got a new smoker from my wife and I spent the afternoon learning about the joys of hickory smoked barbeque ribs. It is a gift that just keeps giving, because I made about 40 pounds of meat in various kinds and flavors because I needed to try everything all at once. …
