本文简介
在本文中将介绍在oracle 11g r2 rac环境下使用grid infrastructure来管理ogg服务，在开始之前，请先按照前文的步骤配置好rac（source）同单实例(target)数据库之间的ogg单向同步，同时确保rac数据库各项服务运行正常,同时启动target端的数据库实例和ogg的mgr，replicat进程，source端ogg的mgr，extract，extract dump进程可以关闭！
实验部分
查看rac各服务是否online，这里3个gsd服务offline属于正常情况！

在source端添加VIP，并赋权限,检查vip是否能正常启动，在本例中运行grid infrastructure的操作系统用户为grid，运行ogg的操作系统用户为oracle
