February 2, 2026 Doug Bidwell

This week there’s another winter storm whacking the eastern half of the United States, and we are also putting together the IBM i PTF Guide a little early in case some of the people working on The Four Hundred lose power. If all goes well, and you are reading this on Monday, then we got it all done before anything bad happened.

This week, we start off with two security vulnerabilities.

First, we have Security Bulletin: Multiple Vulnerabilities in IBM Java SDK affect IBM WebSphere Application Server and WebSphere Application Server Liberty due to the January 2026 CPU, which you …

Big Blue is changing its IP addresses for important stuff once again, and that makes this change a High Impact/Pervasive or HIPER issue for IBM i shops. So, customers have to prepare firewalls and proxies for the upcoming infrastructure changes on IBM Fix Central system, which you can read about more at this link. Public internet IP address are changing for the IBM servers that support internet delivery of fixes and updates for customer system’s software, hardware, and operating system.

So, without further ado, here are the first three editions of the IBM i PTF Guide for 2026, which will end our “Ketchup” Weeks until the next holiday rolls along. (Technically, it is Martin Luther King day in America as we go to press, which is a holiday for many but not for all.)

If you are using WebSphere Application Server Liberty along with Java SE 8, you just got a new lease on life for this combination. IBM had been planning to make Liberty 26.0.0.9 the final release that supported Java SE 8, with interim fixes available through September. Now, as you can see in this announcement, now Liberty will support Java SE 8 up through the 28.0.0.12 release and interim fixes through December 31, 2030.

IBM says that this change was done to give customers more than two more years to upgrade to more recent and modern versions of Java. Liberty …

We start this week with performance anxiety. Well, more like performance degradation. As you will see at this link, if you have installed IBM i 7.4 TR12 or IBM i 7.5 TR7, SQL query plans might be spending more time waiting for I/O pending faults and therefore are performing poorly. There are actually two different but related issues and two different fixes that resolve this issue.

This week, there is also a security vulnerability. See Security Bulletin: IBM i is affected by obtaining information without proper authority [CVE-2025-36371], with more information available here. The fixes for this vulnerability, …
