PM87415: IMS PA ABEND0C4 IPIIPROC AFTER LABEL REC35 + X'43A'

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• IMS PA attempts to find the parent transaction for a program
  switch by utilizing certain fields in the IMS x'35' log record.
  In particular when QLNQCTMP is set it expects to utilise the
  value in QLENQPST to identify transactions associated with that
  particular PST ID resulting in either a pointer to a transaction
  or, a null pointer indicating no transactions could be found. In
  the case where QLENQPST does not contain a value as expected the
  resulting pointer addresses a work area, rather than being reset
  to a null value, which in subsequent processing may lead to
  unpredictable results including ABENDS0C4.         IPI4PROC S0C4

  including S0C4 abend.
  

Problem conclusion

• 1.In processing x'35' when QLENQPST does not contain a value as
  expected, ensure a null pointer is the result of the query
  indicating no transaction is available to satisfy the request.
  2.The IMS PA Transit Engine builds queues based on a 16-byte
  key, this may be insufficient to uniquely identify some
  transaction so the key length is expanded to 32 bytes.
  3.Sundry dialog updates to Help panels and improved validation
  processing.
