【Abstract】 Workflow management system(WfMS) has been used to provide a powerful computation environment for the integration of different applications and the cooperation of different organizations in enterprises. In the current research field of workflow technologies, the distributed workflow engines have gradually caught more and more attentions, and the reliability of the whole system is one of the critical factors to the successful implementation of the distributed workflow system. In this paper.a distributed workflow system with high reliability that runs on different enterprise function domains is introduced-Several measures to improve the reliability of the system are proposed. Meanwhile, the relevant concept of domain, the system infrastructure, the implementation of a process instance and the global control mechanism are also presented.更多还原
