Oracle数据库RAC技术解决方案及分析

Solutions and Analysis Based on Oracle Database RAC Technology

数据库是一个信息系统的核心,它的部署对系统的安全、稳定,以及信息系统的性能都有很大的影响。为了追求信息系统的高效稳定运行,在硬件领域要配置UPS不间断电源、高性能服务器、高速的网络出口。通用性硬件对于一个信息系统来说需要很好配置。软件的配置才是信息系统安全和稳定的关键,所以数据库作为信息系统的核心不断地利用现有环境,提出自己的高可用性的解决方案显得尤为必要。

The deployment of Database, which is the core of an information system, has much to do with the system security, stability, and performance. In order to achieve more effective and stable operation of information systems, UPS （uninterrupt- ible power supply） , high-performance servers and high-speed network outlet should be available in the hardware field. The general hardware is easily configured. The key for information system security and stability lies in software configuration, so it is highly necessary for the database, as the core of an information system, to realize constant use of the existing environ- ment and then to make their high-availability solution.
