  ****************************************************************
  Certain Db2 for z/OS instrumentation records (IFCIDs) can become
  very large under certain circumstances. 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.
