It’s been a non-stop series of exciting and interesting sessions here at IDUG EMEA 2025, as well as a chance to meet with old friends and make new ones.
First of all, from a Triton perspective, Iqbal has already commented on Damir Wilder’s well-attended and well-received presentation on User Experiences with Pacemaker. Well, yesterday it was great to attend John Campbell’s session on “Db2 13 for z/OS Experience with new features for Availability, Resilience and Performance”. John’s sessions continually evolve, adding updated material as new experiences are gained, ensuring there’s always something valuable to learn.
To focus on some key messages from the Db2 for z/OS CAC, I can pick a couple out because they were also reflected in the Monday Keynote and in Haakon Roberts‘ session on “Db2 for z/OS Trends and Directions”. For everyone out there already migrated to V13, and for those still in the process, there’s a key action. Db2 13 is your last chance to migrate from simple, segmented and class partitioned tablespaces, as the last Db2 13 function level, expected to be V13R1M511, about April 2027, will require you to have migrated to UTS PBG and PBR. And while you’re doing that PBR RPN is the future, so you might as well migrate straight to that organisation, and skip PBR APN.
The second message is about Db2 support for Open Telemetry or OTEL. This provides vastly improved capability for effective end-to-end monitoring and tracing, and is something we on the z/OS platform should all be looking for and planning to exploit, with feeds into Instana, Grafana or whatever is your preferred observability tool.
