Research Of Disaster Recovery System Based On Oracle Database

Research on data disaster recovery problem is an issue with importantly theoretical and practical significance in the field of information constructing for government and enterprise. Many of the things need to be done to realize the construction of disaster recovery, such as the learning and research of disaster recovery technology, the analyzing of service system, the design and realization of disaster recovery. The design and realization of data synchronization module is the core of disaster recovery.Focusing on the problem of the design and realization of data disaster recovery, this paper aims at constructing the diff-area disaster recovery system for government finance integrated management system, using Oracle DataGuard and realizing the disaster recovery system. The detailed contents studied in the paper are as follows:(1) The research on the related technology of disaster recovery system. Based on the learning of disaster recovery, the related technology, the analyzing of architecture for disaster system, the procedure architecture and the working way are presented. We analyse the system characteristic and the function for government finance integrated management system.(2) The designing of overall concept for disaster recovery. The principles of design and disaster way are analyzed. The architecture and structure of disaster recovery are researched. The designing of disaster recovery system following is researched and designed detailed.(3) Constructing and realizing the disaster recovery. This paper constructs the data synchronization, the module of synchronization and error detection, constructing the core function for disaster recovery system in view of the frontal researchThe research in this paper has promoted the interaction and inosculation between the theory of database and disaster recovery technology. It is the beneficial exploration for solving the data disaster recovery. The research result in this paper can provide the stable system and efficiency improving for disaster recovery system.
