PH63418: IMSPALOG TOTALTM FIELD INCORRECT AS IT SHOWS EXPONENTIAL TOTAL IMS TIME

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• IMSPALOG LIST and SUMMARY reports for some transactions can
  display exponential Total IMS Time for field TOTALTM; for
  example, 7.79E+11.
  In some circumstances, messages are read by the MQ Trigger
  Monitor BMP which is put on the IMS message queue, but then
  there is no subsequent enqueue for a transaction and thus no
  Input Message Enqueue x35 log record is written. Next, the
  application for the triggered transaction issues a GU to the I/O
  PCB, causing an x'31' DLI GU log record to be written.
  
  This causes IMS PA to incorrectly calculate Total IMS Time
  because it expects a x'35' log record after the x'03' log record
  for the input message.

  This causes IMS PA to incorrectly calculate Total IMS Time
  because it expects an x35 log record after the x03 log
  record for the input message.
  

Problem conclusion

• IMS PA has been corrected to expect the x03 x31 log record
  sequence, with no intervening x35, thus making the correct
  calculation.
