[root@rac1 ~]#
7：TNS 监听器状态及配置

———- ————— —————- — ———— —————– ——— ————–
1 1 racdb1 YES OPEN ACTIVE NORMAL rac1
2 2 racdb2 YES OPEN ACTIVE NORMAL rac2
用 root 用户执行以下所有检查
1：启动或关闭数据库实例
[root@rac1 ~]# srvctl stop instance -d racdb -n rac1
[root@rac1 ~]#
[root@rac1 ~]# srvctl stop instance -d racdb -n rac2
[root@rac1 ~]#
[root@rac1 ~]# srvctl status database -d racdb
Instance racdb1 is not running on node rac1
Instance racdb2 is not running on node rac2
也可以通过如下命令，检查每一个实例的状态
[root@rac1 ~]# srvctl status instance -d racdb -i racdb1
Instance racdb1 is not running on node rac1
[root@rac1 ~]# srvctl status instance -d racdb -i racdb2
Instance racdb2 is not running on node rac2
2：启动或关闭 asm 实例
[root@rac1 ~]# srvctl stop asm -n rac1
PRCR-1014 : Failed to stop resource ora.asm
PRCR-1065 : Failed to stop resource ora.asm
CRS-2529: Unable to act on ora.asm because that would require stopping or relocating ora.DATA.dg , but the force option was not specified
[root@rac1 ~]#
可以用 crsctl status resource -t -init 检查集群资源的状态
3：本地服务器上停止 oracle clusterware 使用 crsctl stop cluster 命令，这个命令执行之后，如果 oracle clusterware 管理的资源中有任何一个还在运行，
则整个命令失败。使用 - f 选项，表示无条件的停止所有资源，并停止 oracle clusterware 系统。
另外，可通过指定 -all 选项在集群中所有服务器上停止 oracle clusterware 系统，如下：
crsctl stop cluster -all -f
也可以使用 crsctl start cluster -n rac1 rac2
