Hi Ralf,
Thanks for bringing this up - that's a great question.
As of now, IBM Cognos Analytics officially supports Java 11, and there hasn't been an official release or roadmap update confirming support for Java 21. The SDK libraries are closely tied to the supported Java version of the Cognos environment, so unfortunately, using Java 21 for SDK calls may not be feasible until IBM provides a compatible version.
I recommend keeping an eye on the IBM Cognos Analytics release notes and the IBM Support site for announcements regarding Java 21 compatibility. Alternatively, reaching out to IBM Support directly might provide a more concrete timeline, especially if you're planning future-proofing or large-scale upgrades.
In the meantime, for stability and compatibility, it's safest to stick with Java 11 for any SDK-related development.
Hope this helps!
Best regards,
Vigan Veliu

Hello together,
I would need the SDK Libs for Java21 to execute SDK Calls against the Cognos installation.
Does anybody have information, when Cognos will be updated to Java21 and needed Libraries will be available?
Thanks for helping.
