基于医院数据库Oracle RAC体系结构的应用研究

Application Research of Oracle RAC System Structure Based on Hospital Database

Oracle是当今非常流行的数据库,现已广泛应用于医疗信息领域,在该领域中,每天24小时均有用户访问数据。如果不能保证这种数据的访问,那将会给医院带来巨大的经济损失和信誉危机。如何将0racle RAC体系结构应用到医院信息化建设中去,使其成为一种具有较高可扩展性和可用性的数据库解决方案。同时,Oracle RAC还解决了导致意外停机和计划停机的问题,从而实现真正容错、灵活的IT基础架构。

Oracle database is a very popular database. It has been widely applied in the medical information field,in the field, 24 hours a day in both the user access data. If we cannot guarantee that the data access, it will give the hospital brings the huge economic loss and reputation crisis. How to use the Oracle RAC architecture is applied to the hospital information construction, make it become a kind of high scalability and availability of database solution.At the same time, Oracle RAC also addresses the cause unexpected downtime and planned downtime problem, thus realizing the fault tolerant, flexible IT infrastructure.
