Abstract: The invention relates to a method and means of workload balancing for a multitude of applications servers. The method comprises a first-step, wherein an application client sends an application request to a request queue of a dispatcher. In a second step the dispatcher is extracting an application request from said request queue. Within the second step the dispatcher selects a certain one of the application servers to which the extracted application request is to be sent to based on a table. The table is administered by the dispatcher and the table comprises an indication of the workload of the application servers. Also within the second step the dispatcher administers the table according to the selection and the dispatcher sends the extracted application request to said certain application server. The method comprises a third step, wherein an application server after processing an application request returns to the dispatcher a response comprising an indication of its current workload.

Abstract: The present invention relates to a computerized method applicable to a set of parties connected via a network, and in particular it relates to a method and system for improving the search for services offered via said network. Said parties are Service Providers offering said services, Service Requesters needing said services, and Service Brokers maintaining information about said services and service providers. Said Service Brokers assist said Service Requestors in finding, for a particular service, the best services from the best Service Providers ranked by the importance for said Service Requestor. Obviously, the acceptance of a particular Service Broker by a particular Service Requestor depends on the capability of providing a (ranked) list of services that best meet the demands of a particular Service Requester.

Abstract: The present invention relates to the area of systems management teaching means and a method for determining and managing application performance. Application Response Measurement (ARM) assumes that the managed application is a self-instrumented component. This requires invasive changes to existing applications or to add explicitly code to newly written applications. Due to this additional effort this will restrict the area of applicability of ARM. The basic idea of the present invention is to instrument not the application components. The present invention contemplates instrumenting the invocation agent instead, which in turn is responsible to call the application for execution. This solution provides application response measurement without any modification of the application being measured. It is the invocation agent that makes the appropriate ARM calls to furnish the instrumentation on behalf of the application.

Abstract: A method of providing workload-management in a Workflow-Management-System (WFMS) includes a first method of automatically determining at least one enclave-graph within a process-model of a Workflow-Management-System (WFM), and a second method of executing the enclave-graphs. The method comprises an enclave-creation-step wherein if control-flow enters the enclave graph a first time, the WFMS creates a workload-management-enclave in the WLM on behalf of activities which are part of the enclave-graph. The method can comprise an enclave-join-step wherein the WFMS joins an activity of the enclave-graph to the workload-management-enclave in the WLM on behalf of the activity. Moreover the method can comprise an enclave-deletion-step for deleting the workload-management-enclave on behalf of the activities.

Abstract: A polite manner is used to discontinue availability of an application-server connected to at least one application-client. The connected-application-server determines what if any connected-application-clients have an open connection to the said connected-application-server. The application-server sends the connected-application-client a demand to switch to a substitute-application-server. The connected-application-client then opens a substitute-connection to a substitute-application-server and closes the connection to the connected-application-server. Finally, the connected-application-server discontinues availability of the connected-application-server by terminating the connected-application-server.

Abstract: In a method for supervising the processing status of activities of a business process managed by a Workflow-Management-Systems or a computer system with comparable functionality (WFMS), the activity is checked to determine whether the processing status of the activity instance has an in doubt status. If an in doubt status is found, a check is made to determine whether a dedicated check-activity is associated with the activity, a check-activity being capable of dynamically analyzing the processing status of its associated activity. If a dedicated check-activity is found, an instance is launched to determine the processing status of the activity instance.

Abstract: A method of performing a transaction on a database. A number of transactions are available to be performed on said database. At least one of said transactions may only be performed if corresponding requirements are fulfilled, wherein the fulfillment of said requirements depends on the prior successful termination of at least one other transaction. Then, said at least one of said transactions is invoked. Depending on stored information relating to prior successful terminations of transactions it is then checked whether said corresponding requirements are fulfilled. If said requirements are fulfilled, said transaction is performed. Then, after a successful termination of said transaction, an information relating to said successful termination is stored.

Abstract: A method and system for providing selective command control within a WorkFlow Management System (WFMS). The WFMS includes a model of a business process. The model defines process activities as nodes of an arbitrary graph and control flows as directed edges of the graph. Upon receiving an issued command directed to a process instance of said model, a it is determined whether the current activity is defined in a command sphere. The command sphere is a sub-graph of the arbitrary graph and defines one or more permissible commands (i.e., commands which can safely be executed during the current activity). The issued command is executed only if it is defined as permissible within the relevant command sphere.
