A model-based business process diagnosis method in Service-Oriented Architecture

Abstract

Service-Oriented Architecture (SOA) has been widely accepted as a development paradigm for application systems. An application system in SOA is composed of heterogeneous and distributed service components and it provides integrated functionalities to end users. When abnormal situation happens in the service system, it is complicated to identify origins that caused the abnormality. That is, fault diagnosis at runtime is one of challenges in service system management. In this paper, we present a method to diagnose service faults at runtime with MBR approach. A target service to be diagnosed is composed of more than one web services based on a business process. The method in this paper receives input values of the target business process, observed values on the business process execution, and output value, and then analyzes suspicious services in the business process based on the predefined business process model.
