Efficient SOA Business Process Reconstruction for Disaster Recovery

With the development of SOA, the hot researches focus on disaster recovery of business systems change to the recovery of SOA business process. SOA- based business has such advantages as loosely coupled, standards-based, and protocol-independent distributed computing, which make SOA-based business systems much stronger than traditional business system. In this paper a kind of SOA business architecture which provides the ability of disaster recovery is proposed. We also clarify the dynamic composition of SOA services theory based on domain ontology. Then we present an efficient reconstruction algorithm which will automatically and dynamically find a replacing service serial for the invalid service of SOA business process from the set of adjacency services. At last, we test our algorithm and verify its correctness.
