APAR status

• Closed as program error.

Error description

• In response to a "resolve-initial-references" request from a
  little-endian client, the server generates a GIOP response
  message with mixed-endian marshalling:  the GIOP response header
  is marshalled in little endian, but the forwarding IOR
  contained within the GIOP response is marshaled in big endian.
  The client ORB is unable to parse the mixed-endian response.

  ****************************************************************
  A little-endian client suffers a CORBA MARSHAL failure while
  attempting to demarshal an INS (Interoperable Naming Services)
  RIR (Resolve Initial Reference) response from a WebSphere
  Application Server for z/OS server.
  
  The INS RIR response from the WebSphere server is a GIOP
  response message containing a forwarding IOR.  The response
  message is not marshaled consistently in terms of its endian.
  The GIOP response header is marshaled in little endian.  The
  IOR itself is marshaled in big endian.  The mismatched endian
  caused the client demarshaling code to fail.
  

Problem conclusion

• The WebSphere Application Server for z/OS server code was
  corrected to marshal the GIOP response with consistent endian.
  
  APAR PK71050 currently targeted for inclusion in Service
  Level (Fix Pack) 6.1.0.21 of WebSphere Application Server V6.1
  for z/OS.
