• The (More) Modern RPG Language

  December 16, 2019 Bob Cozzi

  Back in 1988, I wrote what became the book on RPG III. Then in 1996, I published the RPG IV version and updated it again circa 2000. But in the years that followed, RPG IV became mostly stale; a tweak here and there, but nothing too spectacular.

  In recent years, a wave of RPG IV enhances has been revealed, most notably free-format was completed and helped propel RPG IV, once again into a truly modern language. Although the measure of “modern” for RPG IV seems to lean toward how much free-format syntax is supported; which is ironic considering COBOL and …

• Latest TRs For IBM i Now Available

  November 20, 2019 Alex Woodie

  IBM last week delivered the latest IBM i operating system Technology Refreshes, giving good IBM i boys and girls around the world early Christmas presents in areas like programing, operations, database, and security. Here’s a quick recap of the new stuff in IBM i 7.4 TR1 and 7.3 TR7.

  There were several general enhancements with IBM i 7.4 TR1 and 7.3 TR7. For starters, administrators gained more control over resources available to the Integrated Web Server (the one powered by Apache) with the new capability to install it the Web server in a user-specified sub-system. Admins also get new functions …

• IBM i TRs Bring Database Enhancements, Too

  October 30, 2019 Alex Woodie

  The heart of the IBM i server is its database, so it’s natural that we would see some enhancements to Db2 for i with delivery of IBM i 7.4 Technology Refresh 1 and 7.3 TR 7 next month. The new features may not be earth-shaking, but they deliver some useful functionality nonetheless.

  Let’s start with some foundational changes to the database itself, including the way that database engineers architect the tables that store information in the database. With 7.4 TR1, IBM i shops can now add a new child table to the database without having an exclusive lock on the …

• How The Latest TRs Bolster HA/DR And Security

  October 28, 2019 Alex Woodie

  High availability, disaster recovery, and security are more important than ever, as enterprises look for ways to eliminate risks to their operations, applications, and data. To that end, it’s not surprising that IBM bolstered the HA/DR and security capabilities in IBM i with the latest Technology Refreshes that are slated to begin shipping November 15.

  Let’s start with the new HA features in Db2 Mirror for IBM i, the new business continuity offering that implements an active-active database cluster atop two unique IBM i logical partitions. Db2 Mirror, you’ll remember, was delivered with IBM i version 7.4, so it’s …

• Monoliths, Microservices, and IBM i Modernization: Part 2

  October 14, 2019 Alex Woodie

  Microservices are the future, right? After reading part one of this series, you can be excused for thinking that. Breaking up applications into smaller components brings clear benefits to both the development and operations staff, and clearly is an architectural approach that has a lot of momentum. But it turns out there might be practical limits to how far the microservices approach can take us.

  “Loosely coupled, yet tightly integrated.” That phrase became something of a running joke at an Infor conference attended by this reporter several years ago. The company at the time was betting heavily on its ION …

• Monoliths, Microservices, And IBM i Modernization: Part 1

  October 7, 2019 Alex Woodie

  What’s the best approach for application modernization: Maintain the monolithic architecture, or break it into individual microservices? This is an important question, especially for IBM i shops that are looking to take their considerable investment in encoded business logic to the next level.

  At first blush, the answer seems obvious: Monolithic architectures are bad, and microservices are good. Monolithic architectures, which are still quite prevalent in the IBM i world, proliferated from the 1970s well to the 2000s thanks in part to the popularity of packaged ERP suites that automated a multitude of processes and also to the programming inclinations …

• Midrange Dynamics Dives Into REST With Acquisition

  October 2, 2019 Alex Woodie

  Change management specialist Midrange Dynamics this month announced that it has acquired Rest4i, the UK-based developer of a native IBM i framework for integrating RPG and SQL applications with REST-based APIs. The move positions Midrange Dynamics as a player in the rapidly evolving world of microservices.

  Rest4i was founded several years ago by Stuart Milligan, who headed up DB2 database modernization firm Databorough before selling it to Fresche Solutions (then Fresche Legacy) back in 2013. Milligan foresaw the coming wave of microservices and developed software to “turn the IBM i into a complete REST API server and the RPG developers …

• LANSA Revs Low-Code, UI Modernization Tools

  October 2, 2019 Alex Woodie

  LANSA is under new ownership, but that doesn’t appear to be slowing down the delivery of software, as the company has shipped a pair of product updates for IBM i and other platforms in recent months. That includes a new release of Visual LANSA, its flagship low-code development environment, and aXes, its screen modernization tool for 5250 apps.

  In July, LANSA announced a new release of aXes, its tactical modernization tool for converting 5250 applications into Web interfaces. aXes, which LANSA acquired 10 years ago, provides a way for IBM i shops to convert 5250 screens on-the-fly without any …

• Boutique Footwear Company Finds A Great Fit With Node.js

  August 19, 2019 Alex Woodie

  As one of the premier providers of winter footwear in North America and Europe, Kamik knows what it takes to run a successful manufacturing operation. But when its custom RPG-based ERP system started to show its age, the company turned to Node.js to help modernize production systems, and found that it improved application integration and developer productivity along the way.

  “Legacy” is a word that the folks at Kamik can take pride in. Founded in Quebec in 1898, Kamik remains a family owned business to this day, with factories located in Canada and the United States. Through its brand-name and …

• Midrange Dynamics Speeds Table Updates In Db2 Mirror Clusters

  August 5, 2019 Alex Woodie

  With the launch of Db2 Mirror with IBM i 7.4 in June, IBM heralded the age of continuous availability on the midrange platform, bringing IBM i up to par with Windows and Linux platforms. However, while the new software keeps production data in perfect synch, it’s not so great at keeping up with changes to underlying database tables. That’s an area that Midrange Dynamics is addressing with its change management software.

  With Db2 Mirror, IBM has essentially extended a single-server database implementation into a clustered database with two active nodes. As soon as a piece of data is created, updated, …
