A New Mechanism for Service Recovery Technology by using Recovering Service’s Data

Service recovery technology is an important constituent part of the emergency response technologies. The service recovery goal is to build a technology system of service recovery focusing on the survival of information system services. By analyzing the relationship between service and data, we present a service recovery mechanism by recovering service’s data. We introduce a third party service monitor to monitor the state changes of the service, design the data recovery model, and give an example of quick data recovery. At Last we present a prototype system of service recovery; the experimental results toward the prototype system show that the mechanism which designed by us can greatly improve the service recovery efficiency and it can meet the timeliness requirements of the information service.
