• Enterprises Spend On Systems, Hyperscalers Tap The Brakes

  March 11, 2019 Timothy Prickett Morgan

  For many enterprises, the current generations of processors that come from IBM, Intel, AMD, and the Arm collective are plenty good enough – and available at reasonable price/performance relative to each other and to their predecessors – that the end of 2018 was a perfectly reasonable time to buy what is on the truck. But hyperscalers and public cloud builders, who live and die by the total cost of ownership of their systems as gauged by raw compute power, space required, and power consumed, have to take a longer view. So with new processors coming from Intel and AMD on …

• Guru Classic: What’s That Name, Again?

  March 6, 2019 Paul Tuohy

  Author’s Note: This article was originally published in February 2013. I recently had to hunt out this article when visiting a client. The content is even more relevant as the use of SQL stored procedures continues to grow.

  One of the great things about writing articles and tips is that people will drop you a note to ask a question or tell you how much they liked (or disliked) what you wrote. But even better is when someone drops you a line to let you know they have taken what you wrote and extended it.

  Such was the case with …

• Guru Classic: Custom Perspectives In RDi, Part 2

  March 6, 2019 Susan Gantner

  In my earlier tip I described how to create a custom perspective and I also described one scenario when custom perspectives come in handy. I promised to follow that up with another way to use custom perspectives.

  I’m often asked questions such as:

  • How do I keep my Outline from disappearing when I’m in full-screen edit?
  • How can I see my RPG Indentation view alongside the full-screen editor view of the source member?

  Custom perspectives can be used as one answer to both questions.

  Of course, when you’re in full-screen edit, you can “peek” at any of your views (such …

• Guru Classic: A Bevy of BIFs, %XLATE and %REPLACE

  March 6, 2019 Jon Paris

  Author’s Note: I’m revisiting this classic tip since the original was written back in 2009, long before the introduction of free-form data declarations. In addition, I’ve updated this tip to point to the new %SCANRPL BIF, which impacts this scenario. And, of course, I still regularly encounter RPGers who are confused by the differences between the %XLATE and %REPLACE built-in functions (BIFs). Part of that confusion of course is the result of wishful thinking on the part of those frustrated by the limitations of %XLATE!

  The first thing to remember when deciding which function to use is that %XLATE operates …

• The Problem With ERP

  March 4, 2019 Alex Woodie

  Enterprise resource planning (ERP) software has been the backbone of modern business since it emerged in the mid-1990s. Hundreds of billions of dollars have gone into ERP implementations with the promise of enhanced business processes automation. But was it all worth it? According to new research from Computer Economics, the answer is not clear.

  Every year in its Technology Trends report, Computer Economics surveys a few hundred IT decision makers to gauge their satisfaction level with a variety of technologies. For the past two years, ERP scored dead last in terms of satisfaction and return on investment (ROI). In fact, …

• Tweaking Systems And Withdrawal Symptoms

  March 4, 2019 Timothy Prickett Morgan

  A system product line does not always come out finished and complete, all at once, and its retirement from the sales catalog and the field is not always a simple and smooth thing, either. After a certain amount of criticism from its largest customers, Big Blue last year decided that it would get a little bit more orderly about the latter, as machines are withdrawn from marketing and eventually support. As for the former, well, there are always some nips and tucks that are done here and there as parts of the system are tweaked to meet specific customer demands. …

• Guru: Why And How Not to Use The Aretha Franklin I/O Method

  March 4, 2019 Ted Holt

  The Aretha Franklin I/O Method is still used heavily in RPG shops even though a better method has existed for decades. In the following paragraphs, I explain the Aretha Franklin I/O Method, tell you why you should not use it, and show you the superior method.

  First, let me give credit where credit is due. Although I had been using the Aretha Franklin I/O Method since my System/34 days, I never knew it by that name. Then Dan Cruikshank (now retired) of IBM informed me of this terminology. Here’s how it works:

  Assume an RPG program that needs data from …

• 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 …

• IBM i PTF Guide, Volume 21, Number 9

  March 4, 2019 Doug Bidwell

  This week, the new PTFs coming out of IBM are just for WebSphere Application Server 8.5, and only on IBM i 7.2 and IBM i 7.3. There isn’t much going on otherwise, and this is a blessing, most definitely not a curse.

  I have added a bunch of new links to the spreadsheet that encompasses the IBM i PTF Guide, and these include:

  • IWS/IAS: How To Change the Ports Used by IBM IAS v8.5 and IWS v2.6 Servers
  • WireShark: Instructions for Collecting a Wireshark PC Sniffer Trace
  • AFP: Are AFP Utilities and AFP supported on IBM i 7.3?

  And …

• Power Systems: Driving More Revenue Than Initially Thought

  February 25, 2019 Timothy Prickett Morgan

  Any model takes refinement, whether it is something a human spreadsheet jockey puts together or it is a distributed neural network that is trained with machine learning techniques to do some kind of identification and manipulation of data. So it is with the Power Systems revenue model I put together a month ago in the wake of IBM reporting its financial results for the fourth quarter.

  I did not really mean to get into it at the time. I was just going to assemble a short table of the constant currency growth rates of the Power Systems business and …
