• Guru: Web Services, DATA-INTO and DATA-GEN, Part 1

  April 5, 2021 Jon Paris

  Many of the “Can you help me with. . . ” communications that cross my desk these days include reference to JSON. Sometimes the questioner is receiving JSON in a file, or has to retrieve it from a web service, or needs to generate JSON in response to a query. While there are many ways to handle these requirements, RPG’s built-in DATA-INTO and DATA-GEN can do a lot of the heavy lifting for you and are quite simple once you understand the basics.

  In this series of tips, I am going to start with a basic example that uses both …

• RevSoft Leans On ‘Shadowing’ To Ensure Speedy Job Scheduler Failovers

  March 24, 2021 Alex Woodie

  There are several things that can prevent a high availability failover from executing quickly on an IBM i server, including data synchronization issues, communication failures, and other problems. With the “shadowing” feature in its job scheduler, RevSoft is determined that issues with synching job schedulers do not make that list.

  Jobs demand special treatment in the IBM i high availability world. Care must be taken to ensure that active jobs, including jobs that are in the job queue as well as jobs that are scheduled to run in the job scheduler, are replicated from the primary server to the backup …

• It’s Harder To Hear The Pulse In The Server Market

  March 22, 2021 Timothy Prickett Morgan

  More than any other piece of equipment that does into the datacenter, the server is an indicator of health and wealth. Over the more than three decades that The Four Hundred has been published, we have spent a lot of effort and time to understand how the world is investing in what kinds of servers, including Big Blue’s midrange systems running OS/400 and IBM i, and how the trends change over time. And we are committed to doing that going forward, even though it has just gotten a little bit more difficult.

  For the past several decades – I honestly …

• Guru: Getting Yum And Bash Up And Running

  March 15, 2021 Rob McNelly

  In the March 1 edition of The Four Hundred, I noted that an emphasis on things like system/application modernization and open source solutions gives IBM i newcomers a degree of comfort with the platform. I also made the point that no matter how long you or I have been at this, there are always people, young or not so young, who are new to the platform and come to this site seeking introductory information about various tasks and capabilities.

  With this in mind, I want to delve further into open source for those who are new to it. As …

• Power Systems Security: More Than The Sum Of Its Parts

  February 17, 2021 Tony Perera

  The IBM i platform is no longer an island unto itself. In many companies, there is a diversity of different systems — Unix systems, Linux servers, and Windows environments, not to mention IBM i. Each of these environments brings its own strength and weakness. The goal is to not let these differences hurt something that’s important to you: security.

  Make no mistake: It’s a good thing that Power Systems servers can run multiple operating systems. From an IBM i perspective, it ensures more R&D dollars from IBM to support the hardware. It seems doubtful IBM would spend billions to develop …

• ‘Alarming’ Security Gaps Exposed in IBM i Marketplace Report

  February 10, 2021 Alex Woodie

  If you’ve ever met Ian Jarman, you’d know that the IBM Power Systems business unit executive for IBM Lab Services is not a man who gets easily excited. So when the longtime IBM Rochester executive said he was “alarmed” by the decided lack of basic security precautions in IBM i shops during the recent webinar to discuss the HelpSystems IBM i Marketplace Report, you might get the sense that something is quite wrong.

  Once again, security was at the top of the list of top concerns of IBM i shops in HelpSystems’ annual survey and report, which is now …

  February 1, 2021 Timothy Prickett Morgan

  The word on the street is that IBM is getting ready to do a slew of announcements relating to its Power Systems platform at the end of this month, specifically on February 23. Generally speaking, the announcements are going to focus on IT infrastructure modernization, cloud computing, and application modernization, which are obviously things that a lot of the IBM i base in particular has to consider here in 2021.

  January 13, 2021 Alex Woodie

  With an eventful 2020 thankfully in the rearview mirror, it’s time to start thinking about what 2021 might have in store for us. The IBM i community, like most of the world, could use a little bit of hope at the moment. We asked IBM i community leaders to deliver predictions, and they responded.

  Liam Allan, who is a consultant at Seiden Group and the creator of ILE Editor, has a couple of predictions for IT Jungle.

  “My focus is mainly software. I do still predict Node.js gaining traction on IBM i,” Allan writes. “The tooling is really …

• Security Vulnerability In VIOS, AIX, And Maybe IBM i

  November 23, 2020 Timothy Prickett Morgan

  IBM i shops that use the Virtual I/O Server, which is a cut-down version of the AIX implementation of Unix created by Big Blue, have to be aware that there is a security vulnerability that affects recent releases of AIX and VIOS.

  The vulnerability, announced in Security Vulnerability CVE-2020-4788, affects Power9 machinery running VIOS 3.1 or AIX 7.1 and AIX 7.2, and under what are called “extenuating circumstances” the vulnerability could allow a local user on the system to obtain sensitive information stored on the L1 cache on the Power9 cores.

  The vulnerability was reported on November 18, and …
