• Guru Classic: Looking for Commitment, Part 3

  August 14, 2019 Paul Tuohy

  As companies look to modernize their applications, commitment control can play an integral role. This set of three articles about commitment control was originally published in March of 2009. (See Related Stories below.) The content of the articles has been updated for free-form RPG. In this article, I will take a closer look at how commitment control works by looking at the journal entries for commitment control. I will also discuss the LCKLVL and CMTSCOPE parameters on the STRCMTCTL command.

  Commitment Control And Journals

  Commitment control is dependent upon the use of a journal. A journal is used in conjunction …

• Guru Classic: The Efficiency of Varying Length Character Variables

  August 14, 2019 Jon Paris

  Remember the bad old days when dinosaurs still roamed the earth and the only way to build strings in RPG involved playing silly games with arrays? Or worse still, obscure combinations of MOVE operations? Thankfully those days are far behind us — although sadly there are still a few RPG/400 dinosaurs coding away!

  RPG IV introduced many powerful new string handling options, such as the %TRIMx family of BIFs, but even now there are capabilities in the language that few programmers fully exploit. One of my favorites is variable length fields. This lack of familiarity made this tip an obvious …

• Guru Classic: Everybody Likes Shortcuts! Part 1, Navigation

  August 14, 2019 Susan Gantner

  I wrote the original version of this tip a few years ago but I still find a lot of RPGers aren’t using keyboard shortcuts as much as I think they should be. Since shortcuts can make you so much more productive, I’m re-visiting this topic with a few updates for changes in more recent versions of RDi. It’s also a follow-on to my last Guru Classic tip on RDi keyboard shortcuts.

  I’ve seen a particularly sharp increase in the use of RDi (or Rational Developer for i) by RPGers in recent years. I suspect that has a lot to …

• Setting The Stage For The Next Decade Of Processing

  August 12, 2019 Timothy Prickett Morgan

  It is no secret that Moore’s Law is causing all kinds of grief with chip designers working in all parts of the IT stack. It was bad enough to run out of clock scaling when Dennard Scaling stopped, and the industry has done a great job in making processors more parallel and allowing for them to offload processing to various kinds of accelerators, either on the die, in the package, or in the chassis over high speed interconnects. But even this is running out of gas as processors keep pushing up against the reticle limits of lithography machines because the …

• Is Authority Collection The Right Thing For IBM i Security?

  August 12, 2019 Alex Woodie

  In the past two releases of IBM i, Big Blue has added new security capabilities in the form of the authority collection that allow administrators to see exactly what authorities users need to use their applications. While some welcome authority collection as helping to tighten the security of IBM i applications, others in the IBM i community wonder if the new information is helping at all.

  Authority collection debuted in 2016 with the launch of IBM i version 7.3. When the feature is activated, it monitors what authorities (such as ALLOBJ, SECADM, and so forth) are being called as users …

• 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 …

• Four Hundred Monitor, August 12

  August 12, 2019 Jenny Thomas

  It often seems like there aren’t any new ideas any more. Instead, newer versions of old ideas come back around every few decades (1980s fashion is one current example), or in the case of our first featured article this week, every few hundred centuries or so. For instance, the Trojan Horse was likely the inspiration for the most recent method of breaking into data, another idea that isn’t new but is a simple twist that can result in a frightening outcome for IT managers. You can read about “warshipping” as well as get a little taste of the IT news …

• Stacking Up IBM i And Windows In The Clouds

  August 5, 2019 Timothy Prickett Morgan

  So how does the IBM Cloud running IBM i stack up against the main competition in the midrange, which is on premises Windows Server plus SQL Server from Microsoft as well as that same stack running in the Amazon Web Services cloud? We can’t give you a definitive answer, but we can give you some food for thought as you ponder how good of a deal Big Blue is giving customers who want to put IBM i on the cloud.

  Making comparisons between on premises iron and cloudy infrastructure is difficult and problematic. The good thing about a public cloud …

• 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, …
