IBM i PTF Guide, Volume 27, Number 47
December 1, 2025 Doug Bidwell
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, by IBM i release, are as follows:
