PM15099: ABENDARZ5 WHEN PROCESSING A CORBA REQUEST STREAM . 10/05/26 PTF PECHANGE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• All requests from a Corba Server fail with abendARZ5 if
  the TCPIPSERVICE for IIOP specifies a URM . (The URM for a
  Protocol(IIOP) TCPIPSERVICE specifies the name of the IIOP
  User-Replaceable Security Program.  DFHXOPUS is the sample
  program for this purpose.)
     If you do not specify a URM on the IIOP TCPIPSERVICE, the
  problem does not happen.

  ****************************************************************
  When calling an EJB method in CICS and the IIOP Security exit
  (DFHXOPUS) is active the request processor task will abend
  ARZ5. The abend is issued because the target request stream
  task incorrectly believes that the source task is no longer
  active. The target task determines whether or not the source
  task is active by use of an ENQ, it should ENQ upon the same
  value as the source task (the source task's UOWID) so it
  expects that the enqueue will fail. However the two tasks are
  enqueueing upon different values. This problem occurs because,
  in the source task processing, if a URM is specified on the
  TCPIPSERVICE definition then there is a SYNCPOINT after
  the call to the URM that causes a change in the UOWID.
  So the UOWID passed to the target task is different from
  the one at the time of the source task's ENQ. The target task
  is therefore able to successfully get the ENQ so it believes
  that the source task has gone and abends with an ARZ5.
  This problem only occurs if PTF UK55402 (apar PM08862)
  is applied.

Problem conclusion

• UK55402
  DFHIIRH has been altered to re-enqueue on the new UOWID
  after the call to the IIOP security exit.
