You want to suppress the following error messages in OMEGAMON XE for CICS on ZOS 5.1.0 agent log
KCPPL1262E: THE PCLASS MANAGER EXPERIENCED A CREATE SQL REQUEST FAILURE
WHILE RETRIEVING PCLASS RECORDS, RC=000000CA
KCPPA0262E: The Node Inquiry thread experienced a CREATE SQL REQUEST
failure while updating the TEMS list for a CICSplex, RC=000000D1
KCP0759E THE PCLASS MANAGER WAS UNABLE TO LOAD THE CICSPLEX RULES
Diagnosing the problem
In Hub environment all the Service Level Analysis (SLA) tables were correctly defined, while instead the PCLASS table seems to be missing.
KCPPCL attempted to read the PCLASS table but failed with a 'Catalog Error' or RC=000000CA.
This means there is no such table defined at the Hub, it can occurs if SDA is disabled but you have not installed CICS Agent application support files on HUB TEMS.
Resolving the problem
If you want to keep SDA (self describing agent) disabled, the best course of action for you is to seed the Hub with CICS Application Support files. You can do this via the TEP. Detail for seeding can be found on manual "IBM Tivoli Monitoring: Installation and Setup Guide."
