[root@NODE01 bin]# ./srvctl status asm -n node02 ASM instance +ASM2 is running on node node02. 查看节点应用程序（VIP、GSD、Listener、ONS）的状态： [root@NODE01 bin]# ./srvctl status nodeapps -n node01 VIP is running on node: node01 GSD is running on node: node01 Listener is running on node: node01 ONS daemon is running on node: node01 [root@NODE01 bin]# [root@NODE01 bin]# ./srvctl status nodeapps -n node02 VIP is running on node: node02 GSD is running on node: node02 Listener is running on node: node02 ONS daemon is running on node: node02 以上的命令在任何节点上都可以执行。其中-d表示数据库的名字，-i表示instance名称，-n表示节点的主机名。 ? 2、使用srvctl start/stop命令 srvctl start asm –n node01 # to start the ASM instance srvctl stop asm –n node01 # to stop the ASM instance srvctl start asm –n node02 # to start the ASM instance srvctl stop asm –n node02 # to stop the ASM instance # 这里的node01和node02是这个节点的机器名称，通过以上命令，可以在任何节点上执行，用来关闭与启动任何节点上的ASM。 ? srvctl start database –d racdb # to start the database instance srvctl stop database –d racdb # to stop the database instance # for instance 1 srvctl start i
