Error description
OMPE V540/V550: Incorrect splitting of large IFCID 2 caused data section length to be set to 0 which in turn caused an 0C4 REASON CODE=00000011 abend when accessing IFCID 2 data in realtime displays. Description: IEA995I SYMPTOM DUMP OUTPUT 576 SYSTEM COMPLETION CODE=0C4 REASON CODE=00000011 - Caused by numerous (at least 5) accelators and large buffer pools.

For example on systems with a lot of (Group) Buffer Pools configured and several Accelerators (IDAAs) paired and operational, IFCID 2 can be become very large and has to be split by the Db2 z/OS engine into multiple IFCID 2 records (written at the same time). A similar situation can occurs with IFCID 199 that retrieves data set statistics. Upon request from the various real-time monitoring interfaces, the OMEGAMON for Db2 Collector PE Server sub-task converts IFC records into an internal format and those records that become too large will have to be split into chunks. During this split process an error occurred that was not setting the data set repetition length properly, thus causing the subsequent processing to abend with 0C4 RC 11.
Problem conclusion
The PE Server code logic as been adjusted to properly set the data section length during the IFCID split process. Keywords. 0C4 DGOVSCON FPEVSERV ABEND ZZIDA TEP SITUATIONS E3270UI IDAA FPEUFTDP
