Error description

• Dump Title: OMEGAMON II FOR DB2 DUMP:  TASK=COMMCOLL,ID=V410
  ,MOD=KO2CAPIA,OFFSET=00384A,CODE=S0C9/00000009
  ABEND0C9-9 KO2APCBA+3808 (at PK85147 level), on a 1D08 (DIVIDE)
  instruction.   The 64-bit dividend in REGs 0 and 1 was
  x'0000014A9EF82C00' and with a divisor in R8 of 00000002, the
  quotient exceeded the capacity to fit into a register and this
  led to the abend0C9. Omegamon tried to compute the RESOURCE
  LIMIT percent when the error occurred.  Also, retrieving
  information for a large number of threads results in high CPU
  usage.

  PROBLEM SUMMARY:
  Thread-related data was being retrieved from DB2 more
  frequently than necessary.  Some frequently-used internal
  thread-related routines were called inefficiently.  A thread
  token wasn't assigned for threads in the Detailed Thread
  Exception workspace.  Unicode conversion was being done
  during collection and display of RRSAF end user ID.
  
  PROBLEM CONCLUSION:
  Ensure appropriate collection of thread-related data.
  Streamline calls to internal thread-related routines.  Assign
  thread token for use with DDF statistics.  Do unicode conversion
  only during collection of RRSAF end user ID.
  

Problem conclusion

• Ensure appropriate collection of thread-related data.
  Streamline calls to internal thread-related routines.  Assign
  thread token for use with DDF statistics.  Do unicode conversion
  only during collection of RRSAF end user ID.
