• Now You Can Transform RPG Code Into PHP

  September 21, 2020 Timothy Prickett Morgan

  Assuming an average of 5 million lines of code at IBM i shops – a number I heard recently thrown around – in their homegrown or heavily customized third party applications, IBM i shops are collectively sitting on something like 750 billion lines of code. Just ponder that for a minute.

  This code, which is predominantly written in RPG but with a fair proportion of Java and COBOL plus a smattering of more modern languages, is going to have to be maintained and tweaked in the coming years. Just like it had to be updated and debugged time and again …

• Is It Time To Rename RPG?

  August 24, 2020 Alex Woodie

  Should IBM rename RPG, and if so, what should the new name be? It’s an interesting idea, and one that was recently floated by a member of the IBM i community, who submitted an official request for enhancement (RFE) on the matter. The crux of the argument is that full free-format RPG is such a dramatic departure from fixed-format RPG that it deserves a new name. But will IBM, which owns the language, go along with the change?

  Report Program Generator, or RPG, debuted way back in 1959, at the dawn of the computer age, as a way to replicate …

• Man-DB Brings Documentation to IBM i

  August 12, 2020 Alex Woodie

  IBM i developers who have a question about how a particular command or feature works in open source packages now have an easy way to look up documentations, thanks to the addition of support for the Man-DB utility in IBM i, which IBM unveiled in late July.

  Man-DB is an open source implementation of the standard Unix documentation system. It provides a mechanism for easily accessing the documentation that exists for open source packages, such as the Node.js language, or even for commands, like Curl.

  The software, which can be installed via YUM, only works with open source software on …

• Getting Out Of The Catch-22 Of Application Transformation

  August 3, 2020 Timothy Prickett Morgan

  If starting up a business is hard, maintaining that business can be even more difficult. Conditions and tastes change over time, and applications that drive the business can feel the strain.

  Upper management and IT organizations might have the skills to keep business applications going and make modest changes here and there, or perhaps add a new product line or two. But they usually do not have the time or people to do anything too radical, such as modernizing and transforming those applications to work in completely new ways. This is where bringing in a product and services partner comes …

• ARCAD Generates APIs From 5250 Screens

  July 22, 2020 Alex Woodie

  Many IBM i shops want to modernize their 5250 applications by developing REST-based Web services and API extensions, but they face difficulties getting started. These organizations may want to check out ARCAD Software’s latest offering, ARCAD API, which takes much of the pain and complexity out of the API generation process.

  REST-based APIs have become a standard method for exposing data and business logic to the outside world. There’s an abundance of ways that APIs can be used–pushing data to Web or mobile users, for example, or pulling data from a cloud-based CRM system. Just about any higher-level application function, …

• 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 …

• More Open Source Databases Coming To IBM i

  June 15, 2020 Alex Woodie

  IBM is in the process of bringing several new open source databases to the IBM i platform, including schema-less NoSQL databases as well traditional relational systems. Among the databases that Rochester is targeting are MongoDB, arguably the most popular NoSQL database and a favorite among Web and mobile developers, as well as PostgreSQL, one of the industry’s oldest and most widely used relational databases.

  Databases today almost are like programming languages, with developers mixing and matching databases to handle different functions, often within the same application. DB-Engines.com tracks more than 330 distinct databases, while there are somewhere around 700 programming …

• What’s New In Open Source With The Latest TRs

  April 27, 2020 Alex Woodie

  New technology is exciting. And when it can help you run your business more profitably or efficiently, well, it becomes very exciting. With IBM i, the open source community is arguably the biggest contributor of new technology to the platform. IT Jungle recently checked in Jesse Gorzinski, the IBM i open source architect, to hear how the open source story has improved with the recent technology refreshes.

  Arguably the biggest open source-related enhancement with IBM i 7.4 TR2 and 7.3 TR8 revolves around a change in RPM, the new delivery method that IBM adopted two years ago to distribute new …

• Here’s What’s In the Latest IBM i Technology Refreshes

  April 15, 2020 Alex Woodie

  As expected, IBM today officially unveiled its spring Technology Refreshes for IBM i. Among the goodies that will become available for IBM i 7.4 TR2 or IBM i 7.3 TR8 (or both) are enhancements to Db2 Mirror, a new approach to tape library virtualization, improvements to open source, and new features and functionality around Db2, RPG, RDi, and security, too.

  Months ago, IBM execs circled April 14 on their calendars as the day for the big IBM 7.4 TR2 and IBM i 7.3 TR8 reveal, with the idea that the following week’s POWERUp conference in Atlanta, Georgia (now canceled, but …

• 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 …
