• 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 …

• COBOL Is Not The Problem; The Data Is

  June 1, 2020 Brad Thomas

  The COVID-19 pandemic has put a spotlight on COBOL, with multiple news stories about COBOL systems struggling as unprecedented demands have been placed on them. And then there are the urgent requests for COBOL developers to help ensure these mission-critical systems do their jobs.

  Eventually, the dust will settle, but some tough decisions will loom for organizations that rely on COBOL. The reality, though, is these decisions were already on the horizon because of the constant evolvement of other data management technologies, surging data production and the rapidly increasing average age of COBOL developers. When the dust does settle, it …

• ILEditor 2 Gives IBM i Shops A New Development Option

  May 6, 2020 Alex Woodie

  Liam Allan recently unveiled ILEditor 2, a new integrated development environment (IDE) for IBM i. The new IDE sports a fresher look and better performance compared to the first version of ILEditor, as well as an extensible plug-in system, which should also deliver better code coverage.

  For many years, members of the IBM i community have expressed frustration by the high price, size, and performance of Rational Developer for i (RDi), which is IBM’s flagship development tool for the IBM i community. While the IDE’s performance has improved in recent years, members of the community still bemoan the …

• 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 …

• Guru: Calling RPG Programs From Python, Part 2

  April 27, 2020 Mike Larsen

  In Calling RPG Programs From Python, Part 1, I showed how to call an RPG program from a Python script passing single string parameters as input and output. In the second part of this series, I’ll make the process a little more robust by passing a data structure to the RPG program.

  The first part of the Python script (shown in the first piece of code below) imports the itoolkit modules and assigns them to local names. Next, I set up the first command that adds a library list entry to where the RPG object resides.

  from itoolkit import

• 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 …

• Guru: Calling RPG Programs From Python, Part 1

  March 30, 2020 Mike Larsen

  In a prior article, I showed how to pass parameters to a Python script and execute the script from an RPG program. Based on feedback and my own curiosity, I wanted to see how I could pass parameters to an RPG program and call it from Python. After a bit of research, I found the Python interface itoolkit.

  itoolkit is an open source project provided by IBM as an interface to the XMLSERVICE toolkit, which allows us to call RPG programs, service programs, CL programs, and PASE Shell commands. itoolkit can be installed using an SSH terminal with …

• 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 …

• 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 …

• Thoroughly Modern: Taking The Pulse Of IBM i Developers

  January 22, 2020 Timothy Prickett Morgan

  It takes someone who has experience in application development to create and sell tools that help make a developer’s job easier. We think about the tool creators, but when it comes to getting people to adopt a new technology, the technical sales team at any software company is the bridge that connects developers of tools to the developer of applications who can be helped by those tools. In this edition of Thoroughly Modern, we are talking with Stephen Flaherty, a technical engineer at Fresche Solutions, about what IBM i developers are thinking about and doing today.

  Timothy Prickett Morgan: …
