• EvolveWare Sees Growing Demand for Application Rehoming

  January 24, 2022 Alex Woodie

  The COVID-19 pandemic has acted like an accelerant for IT modernization, as companies seek a better technical base upon which to launch new digital initiatives, often from the cloud. At EvolveWare, which specializes in migrating applications, 2021 brought a flood of business migrating applications off legacy systems, including big iron systems from IBM, and 2022 looks to be just as busy.

  Miten Marfatia founded EvolveWare back in 2001 to address what he predicted would be a surge in application modernization in the new millennium. Marfatia had put quite a bit of thought into the company’s business model, and figured there …

• Some Good Advice About Log4j Mitigation Gotchas

  January 24, 2022 Timothy Prickett Morgan

  The Apache Log4j logging utility written in Java and available since the end of the Dot Com Boom in early 2001, has been installed far and wide into many systems and systems software packages in the more than two decades it has been available. And that is why the zero-day security vulnerability discovered by Chinese computing giant Alibaba on November 24 last year and revealed on December 9 has caused so much concern.

  Log4j is everywhere and that means the Log4Shell vulnerability that Alibaba described makes it particularly scary. But before we get into some of the mitigation advice that …

• Log4j Hits Heritage Version of Navigator for i – No Patch Coming

  January 12, 2022 Alex Woodie

  IBM i shops running the old version of the Navigator for i client should be aware that the software is vulnerable to the Log4j security vulnerability, and there will be no patch to fix it, IBM says in a new security bulletin. There will, however, be fixes coming to other vulnerable components, including IWS, IAS, and IBM i Access Client Solutions (ACS), IBM says.

  Just before we hit the holiday break, the extremely severe Apache Log4j security vulnerability was disclosed to the world, resulting in a frantic effort to patch servers, desktops, refrigerators – just about anything with a …

• The Pivotal Year Ahead For Big Blue And IBM i Shops

  January 10, 2022 Timothy Prickett Morgan

  When we look back on it many years from now, this year, 2022, will be a pivotal year in the history of the Power Systems platform from Big Blue, which was commercially significant starting in February 1990 when the RS/6000 was launched but which obviously traces its roots through the IBM i and OS/400 branches of the Power Systems family tree all the way back to the System/3 launched in July 1969 just 10 days after humans first landed on the moon.

  There are different kinds of pivot points in the history of the IBM midrange platforms, including the launch …

• Critical Log4j Vulnerability Hits Everything, Including the IBM i Server

  December 15, 2021 Alex Woodie

  Hackers gave themselves an early Christmas present this year with a critical security flaw in Log4j, a popular logging framework that is used across many programs, including some that run on IBM i. IBM i shops are encouraged to take this flaw very seriously, as the vulnerability already is being actively exploited in the wild. However, finding where Log4j exists in your stack is not always simple, which makes this particular flaw particularly nasty.

  The Log4j zero-day vulnerability, which was disclosed last week by security researchers with CERT New Zealand, was logged into the National Vulnerability Database as CVE-2021-44228 …

• Guru: Global Variables in Modules

  December 13, 2021 Ted Holt

  When I first learned to program computers (RPG II, COBOL 74), the only kind of variables I knew of were global variables. Any statement within a program was able to use any variable.  It was not until I started my computer science degree that I found out about local variables, which are known to only part of a program. Since that time, it has been my practice to use local variables as much as possible and global variables only when necessary.

  Ideally an RPG program, service program, module, or subprocedure would have no global variables at all, but I don’t …

• Want to Modernize? Great! Now Get to Work

  December 8, 2021 Alex Woodie

  Application modernization has been one of the more popular topics through the course of 2021. After the initial scare of COVID-19 wore off and the pandemic wore on, many companies came to the conclusion that older applications were hobbling their ability to compete in an increasingly digital world. While it’s clear the desire for modernization in the cloud is building, what’s unclear is the extent to which that will translate into action at IBM i shops.

  The COVID-19 pandemic and economic lockdowns rewarded two groups: companies that had largely digital business plans, and those who could run their applications in …

• AWS Offers Mainframe Migration Service. Is IBM i Next?

  December 6, 2021 Alex Woodie

  Amazon Web Services, the world’s largest cloud service provider, last week unveiled a new service to help IBM mainframe customers modernize their workloads and move them to the cloud. Will the cloud giant, which says it’s completely driven by the needs of its customers, launch a similar service for midrange workloads running on IBM i?

  AWS Mainframe Modernization is a new service AWS launched at its re:Invent conference last week that aims at making it “faster and easier to migrate mainframe and legacy workload to the cloud.” In addition to AWS components, the service includes roles for systems integrators, such …

• IBM Encourages IAS and IWS Users to Move to Java 8

  December 1, 2021 Alex Woodie

  IBM is now encouraging IBM i customers to move to Java 8 for their Integrated Web Application Server (IAS) and Integrated Web Services (IWS) environments. While the IAS and IWS environments can still run on older versions of Java, they are not fully supported by IBM, the company announced last month.

  IAS is a lightweight Java application server for IBM i that serves as a foundation for developing and running Java Server Pages (JSP) and Java servlet-based applications. It is based on WebSphere Application Server Liberty, the slimmed down and open version of the traditional IBM WebSphere environment. It has …
