  • 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.
