With the speed IBM has been adding features, it's a good idea to get a recap once in a while.
By Joe Pluta
If you've been following my recent articles, you probably noticed I've been bouncing back and forth between RPG programming and SQL programming. My last article spent a lot of time on SQL. This one will focus on RPG. Specifically, I'd like to discuss a couple of the more-beneficial new features introduced into RPG ILE over the past few releases.
The IBM i has one of the best databases in the world. We’re just using it wrong.
By Rafael Victória-Pereira
Now that I have your attention (and possibly also a few angry comments), let me explain what I mean. It’s a fact that DB2 for i is one of the best databases in the world. This is not something that we just discovered; it’s something that most of us have known for years. However, the functionality provided by that database has evolved over the years, and most (I’d dare say, almost all) applications weren’t updated to make use of those changes. This wouldn’t be a problem if the data volume processed by the applications hadn’t changed. However, the ever-changing nature of business needs (and a little thing called the Internet) made sure that different data and, more importantly, more and more data storing and processing capacity is required to keep up with the competition. What happened in most shops? The systems’ hardware was upgraded, and more workers were hired…to keep doing things the same way!
Business users want new applications now. Market and regulatory pressures require faster application updates and delivery into production. Your IBM i developers may be approaching retirement, and you see no sure way to fill their positions with experienced developers. In addition, you may be caught between maintaining your existing applications and the uncertainty of moving to something new.
In this white paper, you’ll learn how to think of these issues as opportunities rather than problems. We’ll explore motivations to migrate or modernize, their risks and considerations you should be aware of before embarking on a (migration or modernization) project.
Lastly, we’ll discuss how modernizing IBM i applications with optimized business workflows, integration with other technologies and new mobile and web user interfaces will enable IT – and the business – to experience time added value and much more.
More than ever, there is a demand for IT to deliver innovation.
Your IBM i has been an essential part of your business operations for years. However, your organization may struggle to maintain the current system and implement new projects.
The thousands of customers we've worked with and surveyed state that expectations regarding the digital footprint and vision of the companyare not aligned with the current IT environment.
Have you been wondering about Node.js? Our free Node.js Webinar Series takes you from total beginner to creating a fully-functional IBM i Node.js business application.
Part 1 will teach you what Node.js is, why it's a great option for IBM i shops, and how to take advantage of the ecosystem surrounding Node.
In addition to background information, our Director of Product Development Scott Klement will demonstrate applications that take advantage of the Node Package Manager (npm).
Forms of ransomware has been around for over 30 years, and with more and more organizations suffering attacks each year, it continues to endure. What has made ransomware such a durable threat and what is the best way to combat it? In order to prevent ransomware, organizations must first understand how it works.
In this webinar, two experienced cybersecurity professionals go in-depth on the ransomware attack cycle, the need to protect every endpoint, and how to spot signs of infection before data is encrypted by malicious actors.
This webinar also reveals the current state of ransomware with 2021 Malware Survey results and provide effective security strategies for prevention.

Fixed-format and ILE RPG programs can benefit from the use of SQL statements to improve IBM i database access
by Rafael Victória-Pereira
Editor’s Note: This article is excerpted from chapter 11 of Evolve Your RPG Coding: Move from OPM to ILE ... and Beyond, by Rafael Victória-Pereira.
It’s possible to embed SQL code in your RPG programs, allowing them to interact with massive quantities of data at a time, breaking the “process-a-record-at-a-time” RPG traditional approach. Don’t get me wrong—I’m not saying that you should change the way your programs interact with every single data interaction—but some of them could probably have their performance, readability, and reliability improved by SQL. SQL statements can be placed in detail calculations, in total calculations, and in RPG subroutines.
