Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of WebSphere eXtreme Scale        *
    *                  Version 7.0 who are using the HTTP session  *
    *                  replication support.                        *
    ****************************************************************
    * PROBLEM DESCRIPTION: A DuplicateKeyException exception       *
    *                      results when a Web application updates  *
    *                      objectgrid.session.metadata map.        *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    Certain Web applications make nested requests to different
    servlets using the same session.  Nested calls to the
    getSession method should return the HTTP session that was
    created in the first request, but the eXtreme Scale HTTP
    session filter attempted
    to create a new HTTP session on each of the nested requests.
    Because these requests shared the same session
    ID, a DuplicateKeyException exception resulted.
    

Problem conclusion

  • The WebSphere eXtreme Scale HTTP session replication was
    corrected to process nested Web application requests in the
    proper order.
