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.
