• Guru: RDi Code Coverage Without SEPs

  August 12, 2019 Susan Gantner

  My last Guru tip provided an introduction to RDi’s Code Coverage tool that you can use to determine how complete your tests are. In that tip I discussed how to run it using Service Entry Points (SEPs). In this follow-on tip, I’ll continue the exploration of this tool with some additional details plus introduce you to an alternative way to run a Code Coverage session.

  Before going into the alternative approach to running Code Coverage, there are a few details I didn’t mention in the first tip.

  I mentioned that Code Coverage uses the debug engine. What I didn’t mention …

• Guru: How Thorough Was Your Last Test? RDi Code Coverage Can Tell You

  July 22, 2019 Susan Gantner

  When you’ve made changes to one or more programs, you test all the changes – right? And, of course, you also test all the rest of the code just to make sure you didn’t break anything else. Did you do that with your last set of changes? Did you test ALL the code? Enabling you to answer that last question is what RDi’s Code Coverage facility is all about.

  This is an introduction to Code Coverage — the basics of both why and how to use it. Before I go into how to run it, it may pique your interest …

• Guru Classic: Looking For Commitment, Part 1

  June 19, 2019 Paul Tuohy

  Author’s Note: This set of three articles was originally published in March of 2009. (See links in Related Stories below). As companies look to modernizing their applications, commitment control can play an integral role. In my next three Guru Classic articles, I will be updating the content of these articles for free-form RPG.

  In this article, I will discuss what commitment control is, why you may want to use it, and the basic requirements for commitment control. In subsequent articles, I will look more closely at how commitment control works, different ways in which it can be implemented, …

• Speaking The SQL Lingua Franca On IBM i

  June 3, 2019 Timothy Prickett Morgan

  No matter what the job is, we all start out somewhere that is pretty far from being an expert and we depend on our elders and mentors to help us learn all the tricks and get good at the work.

  So it is with the nearly ubiquitous database query language, Structured Query Language, or SQL for short. It started out in the head of IBMer Ted Codd back in 1969, which was coincidentally when the System/3 minicomputer launched and its successor many generations later, the System/38 in 1978, was the first IBM system and the first system in the world …

• Four Hundred Monitor, March 4

  March 4, 2019 Jenny Thomas

  “Dear March, come in!” Readers of Emily Dickinson might recognize the first line of one of her many poems. Although it is unlikely she was thinking of the computing industry as she welcomed the new month, the sentiment is fitting as we already enter the last month of the first quarter of the year. 2019 has been a busy one for IBM as it continues to make headlines throughout the computing world, which will hopefully result in good numbers coming out of Q1. You can count on IT Jungle to be watching for that news, and in the meantime, you …

• More IBM i Predictions For 2019

  February 6, 2019 Alex Woodie

  We kicked off our 2019 soothsaying last week with predictions from IBM i leaders on what the New Year will bring. We keep the ball rolling this week with another batch of predictions from our friends around the IBM i community.

  According to Alison Butterill, IBM‘s the program director for offering management for IBM i, the platform will build off the momentum generated with last year’s 30th anniversary celebrant.

  “The excitement begun in 2018 as we highlighted client innovation around the world will continue into 2019,” Butterill says. “The momentum continues to grow as clients are looking at ways …

• All i Want For Christmas Is RDi Lite

  December 12, 2018 Alex Woodie

  All some IBM i community members wanted for the holidays was RDi Lite. Instead, they’re looking at IBM like the Grinch due to its decision not to offer a free, scaled-down version of the application development tool. What’s more, the community is expressing great displeasure at the manner in which IBM handled the matter through its Request for Enhancement (RFE) process.

  Hassan Farooqi kicked off the campaign for RDi Lite in August 2017, when he posted an RFE on the new IBM developerWorks website that’s designed to facilitate collaboration with its user communities by allowing them to submit ideas for …

• Open Source Is the Future, So Where Does IBM i Fit In?

  December 12, 2018 Alex Woodie

  The IBM i server reached a milestone this year when it turned 30 years old, an amazing feat for a remarkable system that continues to provide computational value to tens of thousands of organizations around the world. But another birthday was celebrated this year that the IBM i community should take note of: The 20th anniversary of the beginning of the open source movement.

  Now, this birthday is a little bit questionable because open source software existed before 1998, of course. But the time is worth marking because an important meeting took place in Palo Alto, California, where the phrase …

• An IBM i Year In Review

  December 10, 2018 Alex Woodie

  Another year is just about wrapped up for us here at IT Jungle. That means it’s time to ease off the news pedal just a tad and enter into a retrospective mood, with the hope of gaining some perspective on where we’ve been in 2018 and perhaps how we’ll start off 2019.

  It all started off rather poorly, way back in. . .

  January

  . . . when the big news was about Spectre and Meltdown, the two vulnerabilities that brought everybody rudely back to the real world following the New Year’s celebration. Nearly all types of processors, including …

• Guru: Addressing A Legitimate Question

  December 10, 2018 Ted Holt

  This is the last Monday issue of The Four Hundred for 2018. My, how time flies! I like to do something different at year end. In previous years I have solved Sudoku puzzles, found my way through mazes, solved the peg game, and more. This year I wish to honor a request that has come from various people and to address what they consider to be a legitimate question.

  As I wrote recently, the question I hear occasionally goes something like this: “Why bother with service programs? Why not use dynamic calls?” Rather than insult the …
