PK76122: ENHANCEMENT CHANGES TO MESSAGES FPEV0158W AND FPEV0162W. THE MESSAGE CHANGES REFLECT CYCLE TASKS NOT HIGH CPU

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The following messages will be modified to provide a better
  context based on the SERVER task usages.
  .
  FPEV0158W DB2A 18:29:33.92 DATA SERVER DETECTED HIGH CPU USAGE
  (78%) OF TASK FPEVDB2I
  
  will be changed to say:
  FPEV0158W DB2A 18:29:33.92 DATA SERVER DETECTED HIGH CYCLE TASK
  (78%) IN FPEVDB2I
  
  Message:
  
  FPEV0162W DSNA 18:29:33.92 TRACES ARE STARTED FOR FURTHER
  ANALYSIS OF HIGH CPU USAGE
  
  Will be changed to say:
  FPEV0162W DB2A 18:29:33.92 TRACES ARE STARTED FOR FURTHER
  ANALYSIS OF HIGH SUBTASK USAGE.
  .
  The corresponding Messages and codes manual will also be updated
  to include the changes.

  PROBLEM SUMMARY:
  see Problem Description
  
  PROBLEM CONCLUSION:
  The OMEGAMON Server subtask PESERVER periodically monitors the
  CPU cycle consumption of its subtasks in intervals of one
  minute. If the CPU cycle consumption of a subtask exceeds an
  internal threshold value, the server issues message FPEV0158W.
  The threshold value may vary with situation and subtask. Cycle
  usage is not % usage of total system CPU, but is the % usage of
  the max CPU available to that task - typically % usage of a
  single CPU. Additionally, the internal server traces are started
  and message FPEV0162W is issued. If the cycle consumption of the
  subtask falls below the threshold within the next sample
  interval, the internal traces are switched off and normal
  processing continues. If the CPU consumption of the subtask
  remains above the threshold within the next sample interval,
  a dump is taken and message FPEV0159W is issued. If the cycle
  consumption of the subtask continues to exceed the threshold,
  the subtask will finally be reattached and message FPEV0161W is
  issued.
