I've just converted one DB2 system to DB2 Version 9 NFM and I'm getting a
problem which manifests itself as huge CPU usage in CICS/DB2 transactions.
These applications work perfectly in DB2 Version 8 on the same z/OS 1.7
system. In DB2 Version 9 the transactions typically use over a minute of
CPU time compared to 0.2 secs on DB2 Version 8. When I profile the V9
transactions, 30% of the CPU time is spent in cross memory and 70% in module
CUNMUNI. I've trolled IBM and Google and can't find anything relating to
problems with CUNMUNI. Has anyone seen anything like this before.

What is you CICS level? Have you applied PK33403/UK05667?
Doc relates to DB2 v8 NEWFUN, but is a CPU issue in CUNMUNI.

Thanks for the response but we are CICS/TS 2.2.
