• Guru: Three Suboptimal I/O Practices

  February 5, 2018 Ted Holt

  I have on numerous occasions looked at source code that I had written in previous years and asked myself, “Why on earth did I do that? What could I have been thinking?” We live and learn, or at least we hope we learn. Today I share three database practices that I see from time to time that can be simplified. Maybe there’s something for you to learn today.

  Before I share the three examples, let me say that I do not consider the more cumbersome code to be wrong. To my way of thinking, any code that produces the correct …

• Rocket Gits Hip to Emerging IBM i Tech

  January 31, 2018 Alex Woodie

  When it comes to managing traditional IBM i development environments, Rocket Software has its bases covered. But as younger technologies and younger developers find their way onto the platform, Rocket found that it had some work to do to ensure that DevOps – or application lifecycle management (ALM), if you like — runs as smoothly as its enterprise customers expect. That’s the case with the vendor’s announcement today around Git.

  Rocket Software today announced that it’s now supporting Git with the Aldon Lifecycle Manager (Enterprise Edition), the company’s ALM product for open systems environments like Windows, Linux, and Unix. The …

• Guru: Sorting In Teraspace

  January 29, 2018 Jon Paris

  In an earlier tip, Teraspace To The Rescue, I discussed how to use teraspace in RPG to permit the storage and manipulation of data that requires more storage than RPG’s 16MB limit. In this tip I am going to discuss how such data can be sorted. Hint: SORTA won’t work!

  Before I get to that though, there is one thing I should mention. In that original tip I said: “For reasons I have never understood, DEALLOC will not null your pointer. So it is a good idea to do it yourself. . . .” IBM’s Barbara Morris pointed out, …

• Transforming The Art Of Code And The Face Of IBM i

  January 24, 2018 Philippe Magne

  (Sponsored Content)  ARCAD has been in business for 25 years, and we have done a lot of technical innovation over those years. We started our business with traditional software change management, on the software change management at that time, which is the combination of having a set of tools to manage developer work and then to transfer from development to test to production. At that time, of course, it was only for OS/400 and then IBM i production platforms. There are some customers with many production machines, but the typical case involves two machines: one for development and …

• Three IBM i Trends To Watch This Year

  January 10, 2018 Alex Woodie

  Happy New Year! As we roll out of bed and shake off the cobwebs of 2017, it’s worth taking some time to think about what 2018 will bring to the IBM i ecosystem, and what it could mean to IBM i professionals, in hopes of getting off to a hot (or maybe just less cold) start to the new year.

  Here are three big trends to keep an eye on as the months gradually turn into a year. It starts off with everybody’s favorite topic, security.

  1. Focus on Security

  When the calendar flipped to 2017, there was a palpable …

• Guru: An Update Conundrum Finally Solved!

  January 8, 2018 Ted Holt

  Russ writes, “Hey, Ted! I was trying to use a pure SQL solution to adjust some data today. My SQL statement worked fine in quality control, but failed in production. I’ve been wondering if the failure was caused by the database or by me! My problem was to renumber sequence numbers for a customer in a table.”

  Russ’s question arrived in my inbox on February 1, 2012. Yes, almost six years ago. At the time, I couldn’t help him. But with the latest technology refreshes from IBM, there is now a way to make the update work properly, and I’m …

• COMMON Education Gets Member-Driven Tweaks

  January 8, 2018 Dan Burger

  COMMON isn’t an organization that’s prone to making major changes. But that doesn’t mean the world’s largest professional organization dedicated to IBM Power Systems – most obviously IBM i – is opposed to improving what it has and introducing a few new ideas. During the holiday season, COMMON president Justin Porter explained to IT Jungle what moves COMMON made in 2017 and previewed some coming attractions for 2018.

  Porter says COMMON is increasing its emphasis on member-driven training and education, and one of the best examples he talked about was the new for 2017 RPG Boot Camp. The Boot Camp …

• BCD’s Nexus Portal Shows Mobile and API Capabilities

  December 6, 2017 Dan Burger

  Development in IBM i focused organizations — transitions from green-screen to browser-based applications and from monolithic to modular code — cannot ignore the portal piece of the puzzle. It’s the portal that provides secure, organized access to enterprise information for employees, vendors and customers using all types of devices connected to the Web.

  Because so many BCD Software customers are interested in mobile access to data and real-time interactions, the development team got to work on making its Nexus portal more useful and convenient for the tablet and smartphone contingents that crave enhancements to their remote gateways.

  “Our development efforts …

• A Profound Replacement For My VisualAge For RPG Applications

  December 6, 2017 Dan Devoe

  In January 2016, I wrote an IT Jungle article outlining how my company, Boston Warehouse Trading Corporation, prolonged the life of our VisualAge for RPG (VaRPG) applications by getting them to work on 64-bit versions of Windows. And I’m pleased to say, that as of Windows 10 Creator’s Edition, they still work. However, the applications are on life support, and we needed to act sooner rather than later to begin the process of replacing the apps whose SDK and support died a premature and painful death.

  We have researched a few application modernization solutions. But it seemed that, when all …

• Guru: A Handy Function for Unit Testing

  December 4, 2017 Paul Tuohy

  I would like to share a technique I use for dealing with lists in an RPG unit test program. According to Wikipedia, “. . . unit testing is a software testing method by which individual units of source code, sets of one or more computer program modules together with associated control data, usage procedures, and operating procedures, are tested to determine whether they are fit for use.”

  In the world of modern RPG, this translates to writing “test” programs to test a specific piece of code. For example, when I write a subprocedure, I will write a test program that …
