Data Management Based On Fault Diagnosis Grid

The essential characteristics of Grid resources are shared and collaboration. With grid computing in science and applications as well as the related research is increasingly deepening gradually mature, grid has been extended to scientific research, deliberations and industrial aspects of the field. Because of grid technology to provide the support and network-based fault diagnosis system exists between the demand for extremely modest properties, grid technology as a fault diagnosis will be key to the core enabling technology to build support for remote collaborative grid fault diagnosis system with important theoretical value and practical significance. This paper mainly studied the fault diagnosis system for data management techniques. Effectively in order to achieve fault diagnosis of grid and management of shared datas in grid-based remote collaborative fault diagnosis system based on existing research on grid remote collaborative fault diagnosis system architecture, fault diagnosis of data management, fault diagnosis and fault diagnosis data transaction data scheduling strategy and create a file replication of data, such as technology start-depth study.The complexity of fault diagnosis data management and the grid system set a request of it architecture. After studying the grid remote collaborative fault diagnosis system architecture on that fault diagnosis of grid system datas are the most important element, and study of fault diagnosis data management are the most critical one of the core elements.Set up a file replication of model of fault diagnosis is the premise of file replication retrieval and optimal scheduling .This paper research the characteristics of fault diagnosis datas and classification in grid environment,it study techinque about that fault diagnosis of grid the key in data management,through the introduction of mathematics model, and set up a objective function mathematics model of fault diagnosis data management based on the optimal positing strategy for create a file replication, and give the transaction flow of fault diagnosis datas.The simulation test use the OptorSim simulation.The results simlated with OptorSim showed the method can improve the performance of the whole system.
