医院跨平台容灾数据库的设计与实现

Design and Implementation of the Cross-platform Disaster Recovery Database of Hospital

目的:通过设计和实现跨平台的容灾数据库,确保医院核心业务不中断,提高工作效率,保障医院信息系统数据安全。方法:在医院现有数据库环境的基础上,使用Oracle GoldenGate技术,设计两套容灾数据库方案,选择较优方案实现。结果:完成医院核心业务切换测试,根据结果优化方案,缩短容灾时间,降低操作难度。结论:建成容灾数据库后,提高了医院核心业务安全系数和运行效率。

Objective: Through the design and implementation of cross-platform disaster recovery database in hospital, ensure the continuous of core business, high efficiency of work and the security of information system data. Methods: Based on the exsiting database environment in hospital, Oracle GoldenGate is used to design two disaster recovery database schemes and the better one is chosen. Results: A switch test of hospital core business is processed, based on the result the scheme is optimised which cutting down the disaster recovery time and complexity. Conclusion: The security and efficiency is encreased after the implementation of disaster recovery database.
