    * PROBLEM DESCRIPTION: Potentially heavy eXtreme Scale         *
    *                      processing can occur on ORB threads.    *

    ****************************************************************
    The processing needed in the catalog service to include a
    container for potential placement can be non-trivial.
    Therefore, as the number of containers in a domain increase,
    this processing can put a strain on the ORB thread pools.
    However, after the message is received in the catalog service,
    the processing needed to include the given container for
    placement can occur on a separate thread.
    

Problem conclusion

  • To mitigate processing on a single ORB thread, you can now
    offload processing to another thread that you specify.
