Recovery policies on a Web services-based business process for minimizing human intervention

Web services enables application developers to implement a new application by composing several Web Services. As the recovery mechanisms of Web services composition specifications are insufficient for automatic recovery of system faults, we propose recovery policies for the fault handling of Web services-based business processes. The suggested recovery policies enable the business process execution system to automatically recover the business process from a system fault. As being determined at design time, the recovery polices brings about the reduction of recovery time at run time. In addition, the recovery policies prohibit unexpected side effects resulted from wrong recovery behavior determined at run time
