PK59343: DFHPI0992 AFTER A MAINTENANCE UPGRADE. PROBLEM GOES AWAY WITH PG COMPONENT TRACE TURNED ON. 08/01/17 PTF PECHANGE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Customer applied a lot of PTFs (CICS or zOS). Since then his web
  service implementation suffers a DFHPI0992 message telling about
  a TRANSACTION ABEND. There is no abend related message in the
  CICS log.
  The problem disappears when the PG component is traced ! (PG=1)
  From a trace DFHPIPM suffers a PGLE TRANSACTION_ABEND exception
  trace entry when PG is not traced.
  TRANSACTION_ABEND is returned because pitl_saved_abcode added by
  PK49155 is not zeroed as expected by DFHPIIS upon return from
  PGLE. Could be that a test of the PGLE return code is missing.

  ****************************************************************
  MSGDFHPI0992 is invalidly issued reporting a transaction abend
  when processing a Webservice request. This only happens if PG
  level 1 tracing if off. The failure manifests itself as a
  spurious abend from DFHPIPM after DFHPITL returns a non-blank
  abend code. DFHPITL is employed in the running of the
  Webservices provider application code.
  
  APAR PK37266 added code to gather abend information should
  DFHPITL be run as an associated task, due to a context switch.
  All DFHPGLE calls that invoked Business Logic were amended to
  return abendcodes into a specific field. This field was always
  set even if an abend had not occurred. It is this field that is
  eventually checked by DFHPIPM and in some cases found to be
  non-blank and is misinterpreted as an abend code.
  
  It was also found that for applications defined as remote or
  dynamic abend codes were not being collected. When using
  Websphere MQ as the transport this could result in incomplete
  recovery action.

Problem conclusion

• UK26477
  DFHPITL has been amended to only return abend information when
  an abend has occurred. Also abend information will now be
  collected for applications defined as dynamic or remote.
