• Open Source Is the Future, So Where Does IBM i Fit In?

  December 12, 2018 Alex Woodie

  The IBM i server reached a milestone this year when it turned 30 years old, an amazing feat for a remarkable system that continues to provide computational value to tens of thousands of organizations around the world. But another birthday was celebrated this year that the IBM i community should take note of: The 20th anniversary of the beginning of the open source movement.

  Now, this birthday is a little bit questionable because open source software existed before 1998, of course. But the time is worth marking because an important meeting took place in Palo Alto, California, where the phrase …

• 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 …

• Guru: Right-Size Your PHP

  December 3, 2018 Alan Seiden

  In my experience doing performance audits, I often point out that while PHP for IBM i comes perfectly configured for small applications, it must often be tuned to handle large workloads. When applications must accommodate hundreds or thousands of users, or use AJAX technology, two easy changes should be considered for PHP and Apache configurations.

  1. PHP_FCGI_CHILDREN Setting In fastcgi.conf

  On IBM i, Zend Server installs a configuration file called fastcgi.conf. Among other settings, it includes PHP_FCGI_CHILDREN, which determines how many PHP jobs run when its Apache server is started. The file — /www/zendphp7/conf/fastcgi.conf (Zend Server 9 or higher) or …

• What Is Happening With RFEs For IBM i?

  October 29, 2018 Alex Woodie

  IBM customers have been encouraged to vote on product enhancements for over a year as part of the Request for Enhancement (RFE) process, and a number of new features have actually made it into IBM i technology refreshes (TRs). What new or improved IBM i functionality will Big Blue work on next?

  It’s hard to say exactly which RFE items will strike a chord with IBM product managers, since the requests can be all over the board and impact a range of components, from the IBM i OS itself and the Db2 for i database to Access Client Solutions (ACS) …

• 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 …

• PASE Versus ILE: Which Is Best For Open Source?

  October 22, 2018 Alex Woodie

  Open source has emerged as a driver of innovation in the past 20 years, and has greatly accelerated technological innovation. The proprietary IBM i platform has also benefited from this trend, thanks in large part to the capability to run Linux applications in the PASE runtime. But some members of the IBM i community are concerned that the fruits of the open source innovation have not tasted quite as sweet as they do on other platforms.

  Linux was the original breakout star in open source software, and so it should be no surprise that the vast majority of software developed …

• Modern Lessons From A Fresh IBM i Developer

  October 8, 2018 Alex Woodie

  Application modernization is a big nut to crack on IBM i. That is to say, there are many ways to tackle the problem, from the code and business logic to the databases and user interfaces. But when it comes to the type of developers you should look for and how they should spend their time, Kody Robinson has a few pointers that may be worth keeping in mind.

  Robinson was a member of the first batch of “Fresh Faces” that IBM put forward in 2017 to showcase the fact that young people are building careers on the platform, and that …

• Guru: Phonetic Functions In SQL, Part 2

  September 24, 2018 Paul Tuohy

  In my previous article I discussed the use of the standard SOUNDEX and DIFFERENCE functions for phonetic processing. I also identified the major problems with SOUNDEX (based on U.S. English and the first character is static) and DIFFERENCE (loose because it is based on SOUNDEX).

  In this article I will discuss how to tackle these problems by writing a customized phonetic function to use in place of or in conjunction with SOUNDEX. The good news is that you do not have to become an expert in phonetics — others have already done the job for you. There are a number …

• Zend Server 2018 Brings PHP 7.2 To IBM i

  September 10, 2018 Alan Seiden

  Since its release on IBM i in 2006, PHP, a popular open source language for building web sites, has become well established on this platform. Like IBM i, PHP has kept up with the times, improving with each release. PHP is installed via a product called Zend Server, which offers a basic, free license for IBM i users, as well as premium paid licenses.

  I wanted to learn more about the latest release, called Zend Server 2018 (pronounced twenty eighteen), so I interviewed Zeev Suraski, co-founder and chief technology officer of Zend, which is now part of Rogue Wave, …

• Guru: Getting the Message, Part 2

  August 29, 2018 Paul Tuohy

  Author’s Note: This article was originally published in October 2009. Since then, I have worked on many modernization projects with many clients and, in every one of those projects, we have used some form of the contents of this (and the following) article. 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. The original articles also showed examples of direct calls to RPG subprocedures from PHP. Given that we now have many languages (Node.js, Python etc.) that interact with RPG, I changed the mechanism …
