PI94867: ABEND EYUO IN EYU9XLOP WHEN PROCESSING A CONTEXT SWITCHED WEB SERVICE PROVIDER TASK 18/03/26 PTF PECHANGE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• CICS is acting as a web service provider.  A handler program
  within the PIPELINE changes either the transaction id or userid,
  causing a context switch to occur and a new task to get created.
  .
  The new task is connected to the original using request streams.
  The new transaction is defined to run locally because it has
  DYNAMIC(NO) and REMOTESYSTEM().  The router URM, EYU9XLOP is
  not called for route select, which is correct.  However, when
  the new task starts the router URM is being called for route
  initiate and being passed an empty DFHDYPDS area.  This call
  is not expected and EYU9XLOP responds by issuing an EYUO abend.

  ****************************************************************
  A Web Service request is received by a web service provider.
  A context switch is done for a transaction that is defined as
  DYNAMIC(NO), REMOTESYSID().
  The transaction is started in the local region and joined by
  RequestStreams.
  During task start initialization, DFHRZXM  BIND_XM_CLIENT, the
  CPSM Distributed Routing Program, EYU9XLOP, is called with a
  DFHDYPDS COMMAREA initialized with nulls except for DYRFUNC
  which is set to 5 (ROUTE_INITIATE).
  This causes EYU9XLOP to abend EYUO and message DFHRZ0203 to be
  issued.

Problem conclusion

• UI53949 UI53950
  The RequestStream module DFHRZRTX has been changed to
  prevent the Distributed Routing Program being called when the
  transaction has been defined with DYNAMIC(NO).
  
  After this APAR is applied the following table
  will be used to determine if the routing URM (DSRTPGM)
  will be called for Web Service requests.
      DSRTPGM       DYNAMIC RemoteSystem
      -----------   ------- ------------
      NONE          YES     YES or NO   Don't Call URM
      NONE          NO      YES or NO   Don't Call URM
      Program name  NO      YES         Don't Call URM
      Program name  NO      NO          Don't Call URM
      Program name  YES     YES         Call URM (Route Selection)
      Program name  YES     NO          Call URM (Route Selection)
