• Lack Of Available RPG Skills Not A Hard Problem To Fix

  September 11, 2017 Dan Burger

  Running an IT department can be a grind. The reliability and manageability of your hardware and software certainly influences how hard the grind becomes, but the job becomes so much easier when you have a staff that removes much of your burden. Successfully developing that staff and creating a positive culture while dealing with turnover and “do more with less” imperatives has a huge impact on whether the CIO or IT director manages the grind or gets ground up. And once in a while, a new addition to the staff comes with a surprisingly positive impact. That leads me into …

• IBM i Salaries Drop Vs. Other Platforms, But It’s Not All Bad

  September 6, 2017 Alex Woodie

  Time was, working on IBM i and its predecessors earned you a premium on your salary compared to other platforms. That’s not the case in 2017, as equivalent jobs on the Linux, Unix, Windows (LUW) front delivers better pay. But the news on the job front is not all doom and gloom, according IBM i staffing expert Bob Langieri, who keeps a close watch on this sort of thing.

  Across the board, IBM i professionals earned lower salaries than their LUW colleagues for various IT positions, with a few exceptions. That’s according to an analysis of IBM i salary data …

• If RDi Was Free, Would You Go For A Ride?

  August 16, 2017 Dan Burger

  Some interesting developments have occurred with the Rational Developer for i (RDi) team. First came the extraction from IBM Software Group and relocation within the IBM i development organization. Then came the integration of RDi development efforts involving IBM and HelpSystems. What’s next? Perhaps a free lightweight version of RDi designed to entice more IBM i developers to trade in their old tools and take a closer look at what they can gain with RDi.

  A new request for enhancement (RFE #108558) may gather enough momentum to bring a free RDi to market. That leads to the question of whether …

• Guru: Teraspace To The Rescue

  August 14, 2017 Jon Paris

  Hey, Jon:

  My team has been trying to resolve a problem for the last few weeks and they are running into several obstacles. The main one has to do with RPG restrictions for data structure length.

  We use a third-party program to process transactions. In the latest version, the vendor has increased the length of the fields in the data structure that we have to pass them. After our programs were changed to accommodate this increase, the RPG program would not compile because the DS exceeds 16,733,104 bytes. The vendor has told us to use teraspace but by itself that …

• Guru: The PHP Path To Victory, Part 2

  August 7, 2017 Chris Ringer

  Part 1 of this article discussed the path a PHP request takes on its way to your backend RPG program through the magic of an external SQL stored procedure. You may need to review the SQL, PHP, and RPG code there before continuing here. If you have not yet downloaded the code to your IBM i (found in Part 1), now would be a good time to do that.

  Part 2 will give you the confidence to troubleshoot those times when something unexpected occurs in this PHP environment. And if you are a developer for large company, the responsibility of …

• Guru: Fundamentals Of Prototyping, Part 1

  July 24, 2017 Jon Paris

  In my series on parameter passing fundamentals, I mentioned the importance of using prototypes to help ensure consistency of parameter definitions; i.e., to help ensure that the parameter passed to the called routine matches what is expected. After that article was published, it came to my attention that many of my readers were unaware of some of the additional capabilities of prototypes, in particular that prototypes can not only identity errors in parameter usage, but that in some cases they can actually fix them for you!

  Before we can begin, though, it would be a good idea to ensure that …

• Guru: Storing Images In An SQL Table, Part 1

  June 26, 2017 Mike Larsen

  In the first part of this series, we’ll look at how we can store images (or other media) in an SQL table on the IBM i. To accomplish this goal, we’ll write an RPG program that reads a table that has the name and location of the images from a folder in the IFS, and writes those images to a table.

  The images will be stored in a column that is defined as a BLOB data type. ‘BLOB’ stands for ‘Binary Large Object’, and is a collection of binary data that is stored as a single entity in a database. …

• IBM i, Watson & Bluemix: The REST Of The Story

  June 21, 2017 Dan Burger

  Integrated Web Services is nothing new for IBM i. But that doesn’t mean there’s nothing new in Web services. A couple of years ago, IBM introduced Bluemix, an integration framework that, among other things, allows applications on other systems to connect with business logic running on i. The Bluemix tooling was designed to consume REST APIs, which can be used to connect Watson and IBM i. That’s where the newness is evident.

  The plumbing that’s necessary to make these things happen is being built by the IBM i development team led by Tim Rowe, business architect for IBM i …

• The Cognitive Systems/500 2018 Edition

  June 12, 2017 Timothy Prickett Morgan

  With the Power9 processor not coming to the IBM i and AIX platforms until sometime early in 2018, rather than right now as many of us were led to believe would be happening, we have some extra time on our hands. So we should all – including the executives who run IBM Systems and its subordinate Cognitive Systems division (formerly known as Power Systems) – take this opportunity to take a hard look at how the IBM i platform is packaged and priced and how a modern integrated platform should be architected.

  The IBM i customer base needs the Cognitive …

• BCD Presto Mobilizes Green Screen To Web App Dev

  May 24, 2017 Dan Burger

  Not every green-screen RPG application needs to be modernized. Some need it more than others. The squeaky wheel gets the grease. The same can be said for desktop apps. They don’t all have to be capable of rendering on mobile devices, but some need it more than others. Now BCD Software is helping in the decision making process by bringing responsive development capabilities to its version 7 release of Presto.

  Presto, of course, is BCD’s most popular modernization tool, while responsive design is the capability to design Web pages that display on any device desktop or mobile with a single …
