在前面的单实例数据库迁移至rac环境配置过程中，介绍了使用standby技术构建单实例主库对应rac物理备库的data guard模型，本节中将介绍rac主库对应单实例物理备库的data guard模型构建；在MAA架构中，ASM提供了存储方面的网格，RAC提供了数据库层面上的网格计算，data guard则着重强调在数据的备份和容灾方面，更多MAA方面的知识，参考下面的链接!
一：主备库的环境介绍
主库： 数据库版本：10.2.0.5 OS版本：centos4.8 64位 数据库名：rac（两个实例） 实例名：rac1,rac2 IP地址:192.168.1.41/24,192.168.1.42/24 db_unique_name: rac 服务名：rac.yang.com 监听器端口：1521 存储类型：OMF+ASM磁盘组，+DATA,+FRA备库：
数据库版本：10.2.0.5 OS版本：rhel5.4 64位 数据库名：rac （单实例） 实例名：orcl IP地址:192.168.1.49/24 db_unique_name: orcl 服务名：orcl.yang.com 监听器端口：1521 存储类型：文件系统+OMF在开始前确保主库rac环境正常，备库只需要安装数据库软件即可，不需要建库
