PM79389: INSUFFICIENT DIAGNOSTIC INFORMATION FOR A ZERO LENGTH QUEUE ELEMENT

APAR status

• Closed as program error.

Error description

• Transaction IMRF retrieves an invalid queue element. Error
  message IMR223E is issued showing DSLMMFS error 025
  (hexadecimal). Dump analysis shows that the queue element has no
  data at all, its length is zero. The provided information is not
  sufficient to identify the invalid queue element in a queue.
  Thus it is not possible to locate the invalid queue element for
  further processing (deleting or moving to an error queue).
  

Local fix

• Improve error diagnostic for transaction IMRF.

  When transaction IMRF retrieved a queue element of length 0
  IMR223E error message was issued and two snap dumps with
  identical dumpids were taken.
  Now error message IMR223E was improved to show the MFS return
  code in decimal (as usual in Merva Esa) and an additional error
  message IMR229E is issued.
  IMR229E issues the QSN of the erroneous message and the name
  of the function which was processed by IMRF.
  So the erroneous message can easily be identified and deleted
  or moved to another queue.
  A snap dump with dumpid 30 (queue buffer) and another one with
  dumpid 127 (TOF) are taken.
  

Problem conclusion

• Improved error diagnosis when transaction IMRF retrieved
  an erroneous queue element of length zero.
