• GiAPA Tackles IBM i Performance Bottlenecks

  March 11, 2020 Alex Woodie

  IBM i shops that are frustrated with persistent performance problems may want to check out an innovative tool called GiAPA. Developed by the Danish firm iPerformance ApS, the tool has alleviated bottlenecks and saved millions of dollars for some of the biggest IBM i shops in the world. Kaare Plesner, the tool’s creator, recently shared his story with IT Jungle.

  In the early 1980s, Plesner returned to Denmark after spending a year abroad working as a mainframe systems programmer. The System/38 was quickly being adopted, but Plesner noticed that it didn’t have the same level of operational tooling that …

• What’s New with RDi Version 9.6.0.7

  March 11, 2020 Alex Woodie

  IBM last month unveiled Rational Developer for i (RDi) version 9.6.0.7, the first release of the popular IBM i development environment in about a year. With this release, IBM is giving developers a handful of new capabilities, including the ability to create procedures out of pieces of code, as well as the ability to test incoming parameters.

  RDi is IBM’s flagship integrated development environment (IDE) for the IBM i platform. The product isn’t universally used across the IBM i community, and it’s not free. But many IBM i professionals swear by the graphical and modern IDE, particularly compared to older …

• 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: Tuning SQL Environments On i

  March 4, 2020 Paul Tuohy

  Author’s Note: This article was originally published in November 2015. This was one of the first DB2 for i Services that I used in anger. I have used a lot since.

  One of the frustrating things about being a speaker at conferences is that when you want to attend another session with a topic that piques your interest, it invariably clashes with when you are speaking. But every now and again, the scheduling gods work in your favor. Such was the case when I spoke at the excellent International i-Power 2015 conference at Wyboston Lakes Executive Centre in the UK. …

• Guru: Practicing Safe Hex in RPG

  March 2, 2020 Jon Paris

  In this tip I’m going to address a question that arises regularly on RPG-oriented Internet lists, namely: “Is there an easy way to convert a character string to its hexadecimal equivalent?”

  One answer, of course, would be to write your own routine using lookup tables, but there is a far easier way. We can take advantage of the system’s hex MI APIs. These were originally surfaced for use by C and C++ but, thanks to the joys of ILE, can be used by any ILE language. Not only that, RPG’s prototyping support makes them really easy to use. In fact, …

• FlashSystem In, Storwize Out After IBM Storage Shakeup

  February 17, 2020 Alex Woodie

  IBM rejiggered its storage array lineup last week when it consolidated the old Storwize arrays into the FlashSystem line and introduced several new FlashSystem offerings. Big Blue now uses NVM-Express drives almost exclusively across the FlashSystem family, which will support deployments in hybrid cloud configurations, while also offering new options for performance-enhancing storage class memory.

  Like other storage vendors have done, IBM has elected to reduce the number of product lines in an attempt to not only simplify naming conventions, but to reduce technical complexity for customers. For IBM, that means eliminating the Storwize brand by merging it into the …

• Guru Classic: A Bevy Of BIFs — Updates

  February 5, 2020 Jon Paris

  In my previous tip I returned to the “Bevy” series to tell you about the latest addition to the family: %ScanRpl. Shortly after completing that tip I realized that there have been a number of more recent BIFs such as %SubArr and some enhancements to existing BIFs like %Trimx that seem to have escaped people’s notice. In this tip I attempt to fill those omissions.

  %Trim: Specify Characters to Trim

  Let’s start with a BIF that hopefully you are all familiar with: %Trim. Before going any further I should point out that when I say %Trim, I am referring to …

• Guru: Copy OUTQ To PDF

  February 3, 2020 Bob Cozzi

  A long time ago I created a CL command named Copy from OUTQ (CPYOUTQ). This command allowed you to selectively copy spooled files from one OUTQ to either another OUTQ or to the IFS as a PDF or text file. My customers use it all the time for monthly archiving of spooled files and redistribution of output. You may have it on your own system.

  Being one of the handful of original advocates for the so called “Openness APIs” for IBM OS/400 (now IBM i), I quickly embraced the system APIs and have used them extensively throughout the decades. One …

• 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 …
