为进一步提升核电厂监督性监测系统数据库的完整性和安全性,设计了监督性监测系统数据库双机热备系统.数据库双机热备的核心是故障转移集群.故障转移集群主要针对数据库服务器和数据库,用来保证服务器和数据库的高可用性(always on).本文主要目的是研究如何在Windows Server 2008 R2实现SQL server 2012高可用组,实现在监督性监测系统数据库双机热备功能.%To further improve the integrity and safety of nuclear power plant supervisory monitoring system database,dual-hot standby system is designed.The core of dual-hot standby is failover cluster.Set for ensuring the high availability (always on) of the database and server. Goal of the this article is to study the realization of SQL server 2012 high availability cluster on Window Server 2008 R2 version,for realizing dual-hot standby function.
