• Melding System Monitoring And Capacity Planning

  April 24, 2019 Timothy Prickett Morgan

  Installing a modern system to run enterprise applications is a pretty tough task, but the job is not done once the iron is in and the databases and applications are up and running. Sophisticated organizations, whether they are large or small, do sophisticated application and system monitoring to keep an eye on how things are running, they have job schedulers that synchronize work to optimize for performance as well as drive up system utilization, and they use all of the information gathered to better plan for the kinds of systems they will need in the future.

  There are many …

• 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 …

• Advice For The IBM i Shop Buying X86 Servers

  October 1, 2018 Timothy Prickett Morgan

  We spend a lot of time at The Four Hundred talking about the Power Systems servers and the IBM i platform, but it we also keep a keen eye on what is going on in the rest of the IT world, particularly when it comes to alternative server hardware and transaction processing and data analytics platforms. There are many, many ways to skin the cats that are the backbone of the business.

  Ok, so that was a bad metaphor. It happens. Like a line of bad code.

  Anyway, it is not lost on us that somewhere around 95 percent of …

• Archive Migration A Success For County Clerk

  September 12, 2018 Alex Woodie

  A county clerk’s office in Illinois that relies on IBM i-based applications to keep its records straight has successfully migrated its archive from an older Ultra-Density Optical (UDO) setup to a network attached storage (NAS)-based device that utilizes newer optical technology. Best of all, the new storage solution didn’t impact response times on the IBM i server one bit.

  The Madison County Circuit Clerk’s Office was up against a mandate to comply with a new State of Illinois law requiring documents in civil court proceedings to be stored electronically and to be available for real-time access. While its JANO Justice …

• Guru: Handling Constraint Violations In RPG

  September 5, 2018 Paul Tuohy

  Author’s Note: The contents of this article were originally published as two separate articles – Handling Constraint Violations in RPG and Handling Constraints Revisited. The content of the article has been updated for free form RPG and some of the coding enhancements that have been introduced, into RPG, since 2009.

  Constraints have been around for a long time but apparently have not quite made it into every programmer’s tool kit. This is partly explained by the fact that implementing constraints in an existing application can be tricky, but it doesn’t explain why constraints are not used extensively in new …

• TEMBO Bolsters Database Modernization Kit

  March 26, 2018 Alex Woodie

  TEMBO Technology Lab is shipping a new release of its software designed to help IBM i shops modernize their databases for the SQL age. The South African company made mostly minor tweaks to its flagship product, dubbed AO Foundation, which should position the product to do more down the road.

  Since it entered the IBM i discussion in 2012, TEMBO has been building database modernization tools and evangelizing the benefits of the SQL Query Engine (SQE) as the modern, up-to-date database engine that IBM i shops should strive to use, as opposed to the older CQE engine that used DDS …
