PM53953: DFHPI0510 E THE PIPELINE MANAGER IS UNABLE TO CREATE OR JOIN A REQUEST STREAM.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• You are using WS-AT based Web Services. The failure is seen
  when a JOIN is being issued for the WS-AT protocol task to
  attach itself to the waiting user pipeline task. A check is
  done to make sure the userid specified on the attach matches
  the userid of the waiting task which was set in the public id.
  There is no need for the userid matching to be done for WS-AT
  protocol.

  Web Services are being used in CICS and WS-AT (Atomic
  Transactions) has been set up. CICS acts as a Web Service
  provider and HTTP basic authentication is set on the
  TCPIPSERVICE. The initial pipeline task runs under the
  supplied user id, which then forms part of the public id of a
  created request stream. A WS-AT protocol message arrives in CICS
  and gets received by a separate TCPIPSERVICE without basic
  authentication active. Eventually WS-AT task running under
  the default user id tries to join the request stream so as
  to attach itself to the waiting application task. Then JOIN
  request fails because the user id of the task doesn't match
  the one in the public id.
  

Problem conclusion

• DFHPIPM has been changed to remove the userid parameter in
  DFHRZSOM JOIN when the public id of a request stream is
  specified.
