Error description

  • If you configure WebSphere Application Server to require CSIv2
    inbound message authentication with basic authentication, you
    cannot use WebSphere eXtreme Scale functions that require a
    callback, such as the session cache. WebSphere eXtreme Scale
    does not send a credential on the callback, except for the
    case where it is running under WebSphere Application Server.
    
    FFDCs on the XC10 will show an error in the callback

    allbackWrapper.commandCallback 266
    Exception = org.omg.CORBA.TRANSIENT

    allbackWrapper.commandCallback

    CAUGHT_EXCEPTION_WHILE_CONFIGURING_SSL_CLIENT_SOCKET: JSSL0080E:
    javax.net.ssl.SSLHandshakeException
    

Local fix

  • The workaround is to use byte[] data type which does not
    require a callback.
    
    ** This workaround does not suffice for session cache.
    

Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of WebSphere eXtreme Scale whose  *
    *                  clients run in a WebSphere Application      *
    *                  Server environment.                         *
    ****************************************************************
    * PROBLEM DESCRIPTION: WebSphere eXtreme Scale functions that  *
    *                      use agents require server-to-client     *
    *                      callback, which can causes failures     *
    *                      to occur.                               *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    Internal functions that use agent functions were updated to no
    longer run a callback from the server to the client.
    These functions include copy to bytes, HTTP session
    replication, and dynamic cache implementations.
