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, …
