Oracle 9i Data Guard技术在水调自动化系统中的应用与实施

Application of Oracle 9i Data Guard to the Waterpower Scheduling Automation System

水调自动化系统是电网运行的重要生产系统,该系统对数据库备份、数据完整性、实时性和并发访问能力等都提出了较高的要求,如何科学地应用商用数据库提供的高级功能构建稳定、可靠、高效的水调自动化系统,成为一个新课题。文中针对该问题,分析比较了多种常见的高可用数据库方案,最终选择应用Oracle Data Guard技术,构建高性能、高可用、低成本、易维护的水调自动化系统。

A waterpower scheduling automation system is an important production system in the operation of a power grid. The requirements of the system for database backup, data integrality, and real-time and concurrent access performance are high. A new task is to make use of the advanced functions provided by the commercial database to establish a stable, reliable and efficient water scheduling automation system. Several popular database application schemes are analyzed and compared, and the Oracle Data Guard technique is chosen for the construction of the waterpower scheduling automation system, which is good in performance, high in availability, low in cost and convenient in maintenance.
