Abstract: Parametric data accumulation means are accumulated in a Terminal Server data file which uses a performance measurement tool program to accumulate operational data occurring in multiple client users which operate on a Terminal Server. Data is accumulated in regard to the log-on time for multiple and various different types of application programs. Each of these parameters are evaluated over a sequence of different operating conditions during periods where the parametric evaluations occur when there is a small number of client users and then over a sequence of expanded operations until there is a large number of concurrent active client users. Subsequently, the Terminal Server data file is formatted and categorized into a database which is used to create a graphical chart of performance plus specific lists of performance for each client-user correlated to each available Application Program.

Abstract: A method and apparatus is disclosed for initiating execution of selected application processors in a clustered multiprocessor system without disrupting the addressing mode of the processors. In one embodiment, this is accomplished by initializing the processors in a conventional way, setting the addressing mode, and then leaving each of the processors in an active mode spinning on a designated Startup Address Location. To start an application processor, the OS simply write a target processor ID and a desired start-up address into the Startup Address Location. The application processor with the matching processor ID reads the Startup Address Location, jumps to the address specified in the Start-Up Address code section, and begins execution at that location. In another embodiment, a processor is provided that does not switch addressing modes when switched from a halt state.

Abstract: A computer-implemented method for converting a UML rendering of an RSM-based metamodel to a UML rendering of a MOF-based metamodel. The method includes the steps of removing inheritance from classes defined within a Repository Services Model (“RSM”) and removing each explicit “construct” operation from each class in the RSM-based metamodel Next, each use in the RSM-based metamodel of an RSM type is changed to use a non-RSM type. After this, each element of the RSM-based metamodel is converted to a corresponding MOF-based element and a determination is made as to whether or not the RSM naming service is used in the RSM-based metamodel, and if so “name” attributes are added that would have been inherited from the RSM classes. A <<metamodel>> stereotype is added to the UML rendering of the MOF-based metamodel; and the MOF properties are set on the UML rendering.
