• IBM i Bucking The Trends, Year After Year

  March 15, 2021 Timothy Prickett Morgan

  There are all kinds of stability that we consider when we choose and use systems. In the IBM i market in particular, we often talk about stability in the sense of the good programming practices that companies or their third-party software vendors have for the applications that they run. Or we might talk about the underlying stability of the operating system, relational database, or middleware software on which these applications depend. Or digging down further, we might talk about the reliability and longevity and predictability of the Power Systems hardware that underlies it all. And then, of course, there is …

• The Humongous Investment In IBM i People

  February 8, 2021 Timothy Prickett Morgan

  It has been common knowledge since the Application System/400 minicomputer platform was launched in June 1988 that the vast majority of customers buying these machines either developed their own code in RPG or COBOL – mostly RPG, except in banking and insurance, which had a mainframe heritage and preferred COBOL – or had access to the source code from third parties and heavily customized it to the point where they were self-maintaining the applications at some point. In many cases, they used a mix of homegrown and third party modules and did the integration themselves.

  This history continues, and is …

• Talk Is Cheap, Action Is Costly

  February 1, 2021 Timothy Prickett Morgan

  Companies pick the platforms for their mission critical systems so they can run them for decades. And it is a very, very big deal when they decide to change those platforms. And, furthermore, it is a hell of a lot harder to change these platforms than many people think, and that is because most of the value of those platforms is locked up in the applications and databases that run atop the servers, operating systems, and middleware.

  It is with this in mind that we always take any survey data that asks IT executives if and when they are going …

• Thoroughly Modern: What’s New With PHP On IBM i?

  December 7, 2020 Timothy Prickett Morgan

  If you use PHP on IBM i, you’ve likely seen some recent announcements about some great changes coming to the open-source language. According to the latest blog post from Zend on PHP 8, there are a number of new functions being introduced including str_contains, str_starts_with, and str_ends_with, preg_last_error_msg and get_debug_type. In addition, the core PHP 8 engine has many new features, optimizations and improvements in the type system, error handling, and consistency. The key areas include:

  • JIT Compiler
  • Fatal errors on incompatible method signatures
  • LSP Enforcement
  • Resource “Classes”
  • Assertion behavior
  • XML-RPC is now in PECL
  • Reflection changes

  This is …

• The State Of The IBM i Installed Base, Part 2

  February 17, 2020 Timothy Prickett Morgan

  In the first half of our analysis of the IBM i installed base, we looked at the number of machines and the number of logical partitions that respondents of the IBM i Marketplace Survey for the 2020 report gave last fall when they took the poll. We did some math and analysis on this to show that there is a large block of customers with lots of machines and lots of partitions that are just as important to Big Blue as those with big, fat NUMA servers.

  In the second half of this series about the state of the IBM …

• The Distinguished Professionals Of IBM i

  February 17, 2020 Timothy Prickett Morgan

  We use the term legacy a lot in the IBM midrange and mainframe markets, and not necessarily in the good way we talk about political leaders or business executives or sports stars all leaving a legacy behind of their body of work. I use the term when it means something precise – legacy applications, for instance, are the ones that originated back in time and that have not been modernized in any substantial way because perhaps they don’t need to be.

  I prefer the term vintage when I am talking about hardware and software releases because that conveys a …

• Security Still the Top Concern as Privacy Regs Loom

  February 12, 2020 Alex Woodie

  For the fourth year in a row, security is the number one concern of the IBM i installed base, according to HelpSystems’ 2020 IBM i Marketplace Survey. IBM i shops are clearly concerned about the need to prevent unauthorized access to applications and data. But security’s first cousin, data privacy, also stands to gain more attention with the recent passage of data privacy laws, such as GDPR and CCPA.

  HelpSystems released the results of its latest marketplace survey last month, as it has done for the past six years. And just as it has for every year since 2017, security …

• The State Of The IBM i Installed Base, Part 1

  February 10, 2020 Timothy Prickett Morgan

  This is the time of the year that people assess where we are at so we can figure out where we are going. So we think it is appropriate to ponder the current state of the IBM i business.

  There isn’t just historical precedent for pondering the state of things this time of year; the pondering, in a certain way, drives history. The end of the prior year is mostly gone from memory and focus shifts toward fulfilling the promise of the current year. It is human nature to mark time this way, driven in part by the seasonal nature …

• IBM i Shops Walking A Flatter Upgrade Path In 2020?

  January 20, 2020 Timothy Prickett Morgan

  In general, there is a rough correlation between growth in online transaction processing workloads and related enterprise applications, and the growth in the overall economy. At some point in the past, when OLTP was relatively new and many companies were still doing batch processing, OLTP workloads grew many times faster than gross domestic product – much as many data analytics, storage, and machine learning workloads are doing today.

  So when we see that IBM i shops are looking to upgrade in 2020 at a much higher level than we would expect based on historical and anecdotal trends, it gets our …

• Participate In The 2020 IBM i Marketplace Survey Webcast

  January 13, 2020 Timothy Prickett Morgan

  Every fall for the past six years, HelpSystems puts out the call for the IBM i community to participate in its annual survey of the base so we can find out what is going on out there in your shops. And then as the new year just gets going, the company hosts a webinar that goes over the results of the survey with commentary from a bunch of people.

  Tom Huntington, the executive vice president of technical solutions at HelpSystems, will host the webinar, and I plan to attend as do two familiar IBMers and a new one. That would …
