• 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 …

• What Is The State Of Your IBM i Modernization?

  December 3, 2018 Amanda Blackburn

  (Sponsored Content) Each IBM i shop has its own history with the platform, and its own approach to dealing with change. Some run the server like it’s still 1988, while others have invested time and money to modernize their systems and applications. Understanding the state of modernization across the IBM i community as a whole can help us discover where each of us sits on this IBM i journey and help us prepare our organizations for new challenges and opportunities.

  The IBM i server turned 30 this year, which was the cause of much celebration at industry events around the …

• High Schools: The New Recruiting Grounds for IT Jobs

  November 28, 2018 Alex Woodie

  Companies that are having trouble filling entry-level IT jobs due to the tight job market and low unemployment rate may want to check out another resource for finding and attracting workers: their local high school.

  Recruitment, retention, and training of new talent are always hot topics during the roundtable discussions that take place at the CIO Summit. “It’s always a very fruitful and productive topic to see what CIOs are doing,” says Alan Seiden, who has been running the bi-annual event for IBM i tech executives for the past year-and-a-half.

  So when one of the CIOs at last month’s …

• MB Software Gets A Handle On Remote SQL Jobs

  November 28, 2018 Alex Woodie

  System administrators who get frustrated with the inability to see which SQL jobs coming in through ODBC are causing problems on their IBM i server may be interested in a product called Work with Active SQL (WRKACTSQL) from MB Software and Consulting, which recently announced the tool will be free through the end of the year.

  SQL is just about as close to a universal language for business as you can get. While there are other (i.e. “native”) methods of fetching data from Db2 for i, nearly three-quarters of IBM i developers report using SQL, making it the number two …

• Scaling Up For Cyber Monday With IBM i

  November 26, 2018 Alex Woodie

  A fulfillment company that’s expected to process millions of transactions on an IBM i server today will lean heavily on a slim layer of RPG-based Web services technology to keep the commerce flowing for its large clients. But there’s nothing stopping the middleware, dubbed iWebSrv, from simplifying data integration for clients in other industries.

  Retailers work all year to ensure they’re ready for the massive surge of traffic that springs up after Thanksgiving. For bricks-and-mortar types, Black Friday is their make-or-break day, while those with an omni-channel bent have Cyber Monday prominently circled on their calendars.

  Consumers are expected to …

• Guru: When Is An Error Not An Error?

  November 26, 2018 Jon Paris

  When is an error not an error? When it is expected! In this article I want to discuss the use of RPG’s MONITOR op-code and discuss ways in which it might change the way you code RPG. I was prompted to write up my thoughts on this subject as a result of being quizzed by students at a recent RPG & DB2 Summit as to why I was using Monitor blocks rather than more conventional RPG techniques in my examples.

  So what do I mean by expected? Basically I mean those errors that you know are going to happen …

• iSphere Upgrade Bolsters RDi Even More

  November 7, 2018 Alex Woodie

  When it comes to IBM i programming tools from IBM, Rational Developer for IBM i (RDi) is the integrated development environment at the top of many professionals’ wish lists. However, the IDE’s functionality is lacking a few departments, which provides an opportunity for innovation in the community, as IBM originally envisioned. One of the projects that’s been running with the ball is the popular iSphere project, which recently unveiled a new release.

  iSphere is a free plug-in for RDi and WDSC that was first released by Frank Hildebrandt of Task Force IT-Consulting back in 2013. The original idea behind the …

• Serving Up Fast, Fresche Interfaces for IBM i

  October 31, 2018 Alex Woodie

  “Time is money,” as Benjamin Franklin once said. With enough of either, IBM i shops could accomplish all of their modernization goals. But of course, both time and money are limited, which is why tactical tools like the Presto modernization tool from Fresche are gaining traction.

  Fresche’s Presto is an IBM i modernization tool that takes 5250 output from applications and converts it on the fly into HTML that can be rendered in a standard Web browser. The software can also work with the RPG Open Access handler from IBM to power GUIs that have RPG-based back ends but …

• Break Out Of Your RPG Comfort Zone

  October 29, 2018 Amanda Blackburn

  (Sponsored Content) IBM i developers, like all developers, can get stuck in a rut sometimes. The well-worn path that RPG provides is familiar and reassuring, but it doesn’t necessarily lead your company where it needs to go. That’s why exploring newer IBM i language alternatives, like Node.js, can provide a fresh path towards the goal of business innovation.

  The rapid ascent of the Node.js programming language over the past five years has been well-documented. While Java remains a popular business language, Node.js is now the world’s most popular development framework in all of computing, according to the 2018 …

• Kubernetes Container Control Comes To Power Systems

  October 29, 2018 Timothy Prickett Morgan

  The moment that Google created a clone of parts of its internal Borg cluster and container management system and open sourced it as the Kubernetes project, the jig was pretty much up.

  Google had done a lot of the fundamental work to bring containers to the Linux platform starting way back in 2005, and had shared its techniques with the open source community, leading directly to the Docker container format and the engine that runs it atop the Linux kernel. While Docker, the company, got a jump start with its Docker Swarm container orchestrator and then its fuller Docker Enterprise …
