Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server V9.0 configuration migration tools   *
    *                  performing a clone migration.               *
    ****************************************************************
    * PROBLEM DESCRIPTION: The old and new clone environments are  *
    *                      competing for control of the web        *
    *                      server traffic.                         *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    Clone migrations are leaving web server automatic plug-in
    generation and propagation enabled in both the old and new
    environments. This can cause competion for web server traffic,
    and might send traffic to the new environment before the user
    is ready to have it handle traffic.
    

Problem conclusion

  • Updated the Post Upgrade process to change managed and
    unmanaged web servers to MANUAL plug-in propagation and
    generation in newly cloned environment. Then generate a file
    with custom wsadmin commands that will re-enable AUTOMATIC
    generation and propagation in the new environment while
    disabling it in the old environment.
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 9.0.0.2.  Please refer to the Recommended Updates
