oracle 数据库集群 怎么看集群名称及集群节点的相关信息

$ cd $CRS_HOME/bin

$ ./crs_stat -t 查看RAC各节点所有服务的信息及状态

$ ./crs_stat |more 由于上面指令显示的信息看不完整，这里可以显示各服务的详细信息

$ ./crs_stat -p |more 不仅有详细信息，还有对其他服务的依赖关系

如何查看当前的oracle是单机还是集群

以管理员登录Oracle;

sqlplus /  as sysdba

登录成功后，输入show parameter cluster_database;如果value的值为FALSE，说明是单机；如果value的值为TRUE，说明为RAC。
