可以仔细看 STATE_DETAILS       一栏 如果数据库节点2 实例关闭的话,会显示实例关闭

ora.orcl.db
      1        ONLINE  ONLINE       p520                     Open               
      2        ONLINE  OFFLINE                               Instance Shutdown  

如果vip发生漂移的话,会显示failed over

ora.p650.vip
      1        ONLINE  INTERMEDIATE p520                     FAILED OVER        

从上面我们命令我们可以很详细的看到各个资源组的状态,数据库实例处于什么状态,vip是否发生漂移等
