• IBM Brings Active-Active Mirroring Into Db2 For i Database

  April 24, 2019 Timothy Prickett Morgan

  As a platform that is approaching 40 years of deployment within enterprises that can’t afford downtime with their mission critical systems – that’s counting the System/38 as well as the AS/400 and its follow-ons as part of the same continuum – it is no surprise at all that IBM midrange systems running RPG and COBOL had some of the most sophisticated – and perhaps the only application-centric – clustering software ever developed.

  Concurrent with the launch of IBM i 7.4 this week, Big Blue is rolling out a new kind of database clustering, which is called Db2 Mirror, that is …

• Settling In With IBM i For The Long Haul

  February 11, 2019 Timothy Prickett Morgan

  If nothing else, the IBM i platform has exhibited extraordinary longevity. One might even say legendary longevity, if you want to take its history all the way back to the System/3 minicomputer from 1969. This is the real starting point in the AS/400 family tree and this is when Big Blue, for very sound legal and technical and marketing reasons, decided to fork its products to address the unique needs of large enterprises (with the System/360 mainframe and its follow-ons) and small and medium businesses (starting with the System/3 and moving on through the System/34, System/32, System/38, and System/36 in …

• The IBM i Base Did Indeed Move On Up

  January 21, 2019 Timothy Prickett Morgan

  This time last year, in the wake of the 2018 IBM i Marketplace Survey report put together by HelpSystems and based on survey data gathered in the fall of 2017, we said that the IBM i base was ready to move on up to newer iron. And guess what? Based on the results of the survey done in October 2018 and released in the 2019 IBM i Marketplace Survey unveiled last week, it looks like a pretty healthy portion of the base did in fact get off older iron and move to shiny new Power9 iron. In some cases …

• Guru: Addressing A Legitimate Question

  December 10, 2018 Ted Holt

  This is the last Monday issue of The Four Hundred for 2018. My, how time flies! I like to do something different at year end. In previous years I have solved Sudoku puzzles, found my way through mazes, solved the peg game, and more. This year I wish to honor a request that has come from various people and to address what they consider to be a legitimate question.

  As I wrote recently, the question I hear occasionally goes something like this: “Why bother with service programs? Why not use dynamic calls?” Rather than insult the …

• IBM Winds Down PowerVM V2, Nudges Customers To PowerVM V3

  November 12, 2018 Timothy Prickett Morgan

  It may not occur to you, but the PowerVM server virtualization hypervisor that Big Blue created for Power Systems servers has a version just like every other piece of software in the world, and like all software, it ages and eventually it is retired from the field in lieu of more modern code.

  In announcement letter 918-129, IBM let it be known that PowerVM V2, of which there were three releases, will be withdrawn from marketing on February 19, 2019 and will have its support withdrawn on September 30, 2020. That may seem like a long time away from …

• 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 …

• Systems A Bright Spot In Mixed Results For IBM

  October 22, 2018 Timothy Prickett Morgan

  It is hard to describe a company that raked in $18.76 billion in revenues and brought $2.69 billion of that to the bottom as limping along. But watching IBM, as revenues declined by 2.1 percent, after many years of gentle declines, and profits off by 1.3 percent, it sure does feel that way sometimes.

  In past years, as Big Blue crested above $100 billion in sales, its growth was limited by its total addressable market among large enterprises that can only get so large, too, as well as by the limits of its imagination for peddling wares to small and …

• Legacy Apps Kept Alive Just for Data, Survey Suggests

  October 17, 2018 Alex Woodie

  A good percentage of IBM i shops are keeping legacy applications running after their “use by” dates have expired for no other reason except the data they hold still has value, despite the security and privacy risks that those old systems pose to the organization, according to a new survey released by SoftLanding Systems yesterday.

  SoftLanding Systems surveyed several dozen IT professionals at recent industry events, including International i-Power 2018 and PowerUP18, and concluded that 63 percent of IBM i shops are maintaining a legacy application just to access the data.

  Asked why the organizations had not migrated the data …

• As Systems And Storage Go Virtual, Networks Must Follow

  June 18, 2018 Timothy Prickett Morgan

  We spend a lot of time getting down in to the nitty gritty of the Power Systems iron and its IBM i platform, with occasional forays into AIX or Linux where it is important. But sometimes, we take a high-level view of a phenomenon going on in the IT sector or in business in general and we give you some thoughts about how something might affect the IBM i ecosystem.

  This is one of those essays, and we think there is something important going on, and quite frankly, we are not sure how it will affect IBM i. And that …

• The AS/400 Lessons Come Back Around With Power9 Systems

  December 11, 2017 Timothy Prickett Morgan

  For many years before I took the job as Systems Editor at The Register and in the years since I left that post, the joke about any new system or device was: “Yes, but can it run Crysis?” Those of us writing stories would bend a few sentences around the idea, particularly with Linux systems, which if you equipped them with the WINE Windows emulator might allow said device to indeed run that first-person shooter game that was popular from 2007 through 2013.

  As we think about the new “Witherspoon” Power9 server that IBM launched last week, we can’t help …
