PK19465: APPLICATION TRACE TO MEMORY RESULTS IN INCORROUT. LOST DATA DUE TO VSAMTSK OR IFCARLC

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Invoking application trace to memory may result in incorrect
  data in many of the ATF displays. Statement number (STM#) may be
  incorrect. The number of SQL calls reported on high level panels
  may not agree with the detail.
  
  INCORROUT on panels ATVP,ATD1, ATD2, ATSI
  
  This will also effect the equivalent CUA screens
  
  
  Message
  O21152   NUMBER OF TRACE RECS LOST DUE TO IFCARLC:  00001252
  O21152   NUMBER OF TRACE RECS LOST DUE TO VSAMTSK:  00001252
  in the OMEGAMON DB2 address space
  DSNW133I in the DB2 address space
  
  due to volume of trace data generated.
  

Local fix

• For lost data conditions consider refining the selection
  criteria of what is being traced.
  
  Consider usermod TKANSAM(KO2MOD04) to increase IFI buffer size
  for ATF

  * RECOMMENDATION: APPLY the PTF                                *
  ****************************************************************
  In a high-activity trace (ATF), DB2 may generate records
  faster than the ATF process is writing them out, resulting
  in non-zero value for IFCARLC and VSAMTSK.
  

Problem conclusion

• Introduce code to write records when internal buffer begins
  to fill.
