• Momentum Builds For Code For IBM i

  November 7, 2022 Alex Woodie

  Energy and excitement are building in the IBM i development community thanks to Code for IBM i, the VS Code extension that enables users to write and edit RPG and COBOL code in a Web browser. Spearheaded by Liam Allan, who now works for IBM, the lightweight alternative to RDi is approaching critical mass among IBM i developers desperate for something new.

  For many years, IBM i shops had few options available to them when it comes to developing ILE applications for IBM i. IBM’s default recommendation was Rational Developer for i, the Java-based integrated development environment (IDE) that …

• OpenSSL Flaw No ‘Heartbleed,’ But Other New Vulns Detected

  November 2, 2022 Alex Woodie

  The cybersecurity world has been sitting on pins and needles for the past 48 hours, ever since news of a potentially devastating new flaw in OpenSSL started to leak out early Monday morning. That flaw turned out to be not as bad as initially feared, but that shouldn’t stop IBM i shops from patching other recent flaws, including some pretty serious ones in WebSphere Liberty, Java, the CCA, and Zlib.

  News started to emerge earlier this week of a critical OpenSSL flaw that required the utmost attention. The flaw could be a concern for just about everybody, including IBM, …

• Flash Storage Is Table Stakes For Any IBM i Cloud

  October 31, 2022 Andrew Johnson David Fahrenkrug

  After a long wait, the IBM i market is finally entering the true cloud era, one where utility pricing, performance, flexible capacity, and managed services are all available for companies running the IBM i operating system and RPG, Java, PHP, and sometimes COBOL applications against the Db2 for i relational database.

  But there are clouds, and then there are things that should not rightly be called a cloud.

  And we think that if you are a modern cloud, then your primary storage has to be flash and that there is no place for a hard disk drive based on spinning …

• Finally, IBM i Cloud Dev Instances That Are Powerful And Cheap

  October 24, 2022 Chuck Paolillo

  Back in the old days, when IBM had relatively inexpensive entry AS/400 and iSeries machines and was willing to lease them at special low rates to developers, it was possible for software houses and independent code slingers to get their hands on machinery to create and modify applications. Those days are long gone, and it has been very difficult to replace that cheap and usable functionality in the marketplace.

  With Windows Server and Linux platforms, things are a lot easier because developers can create a variant of their X86 server environment right on their desktops or laptops, and if need …

  October 24, 2022 Doug Bidwell

  We are happy to report that there are no new security vulnerabilities in the IBM i stack and related open-source software this week – at least as far as we know. So, rejoice in that. There are a bunch of HIPER PTFs and fixes for Java that span the current IBM i releases on support and extended support, so be aware of those.

  And just a reminder to keep checking out The Four Hundred in each issue as we drill down into new details related to the Tech Refreshes announced this month, and that are coming in December.

  Now, here …

• Are Code Freezes a Thing of the Past?

  October 5, 2022 Alex Woodie

  After months of work on your modernization project, the consultant helping you is almost done. That’s the good news. The bad news is that the consultant is now asking you to put a code freeze on changes to your old application. It’s not clear whether the code freeze will lasts two months or two years, but it’s absolutely necessary, you’re told.

  That’s the scenario that many enterprises have faced over the years. Whether it’s a monolithic RPG application running on IBM i or a distributed Node.js application running in the cloud, if there are tight dependencies in the components that …

• Software Supply Chain Attacks Are A Growing Threat

  October 3, 2022 Alex Woodie

  There’s a lot going on in the world right now, so you probably don’t need something more to worry about. But the cat-and-mouse world of cybersecurity never sleeps, and one of the threats keeping the good guys up at night right now is the growing risk of software supply chain attacks. Unfortunately, security through obscurity won’t provide as much protection for the IBM i server this time around.

  Just what is a software supply chain attack? According to the U.S. government’s Cybersecurity and Infrastructure Security Agency (CISA), a software supply chain attack occurs when “a cyber threat actor infiltrates a …

• Thoroughly Modern: Latest IT Trends – Bring Security, Speed, And Consistency To IT With Automation

  August 8, 2022 Alan Hamm and Chris Koppe

  The irony of many IT departments is that they have spent many decades automating aspects of the business, literally encoding business processes and interactions with customers, partners, and suppliers to make those processes consistent and fast, but many of the processes used in the IT department itself are done manually and rely on the “tribal knowledge” of the system and application experts.

  This is not only not necessary in many cases today, thanks to a myriad of automation tools that can be brought to bear on IT operations, but it is also dangerous and extremely risky. The systems that run …

• Guru: IBM i Experience Sharing, Case 5 – Using IBM i PDI Charts To Answer Performance Questions

  July 18, 2022 Satid Singkorapoom

  During my long career as an IBM i performance specialist, it was natural for people to ask me performance-related questions of various kinds. But in many cases, it seemed to me that the customer could not understand my answers, and I could not provide supporting evidence due to the lack of a performance reporting tool that could produce easy-to-understand explanatory information. The situation changed for the better with the availability of IBM i Performance Data Investigator (PDI) tool as of release 6.1. I would say that the PDI tool provides charts of information that resemble those used by business people …
