ASMCMD-8102: no connection to ASM; command requires ASM to run

安装好oracle 11g rac 后，进 asm 操作时，

一直提示这个报错，命令也无法执行。

[grid@db1 ~]$ srvctl status asm
ASM 正在 db1 上运行

如果没有运行asm实例，使用以下命令打开。

[grid@db1 ~]$  srvctl start asm 

检查状态正常，我这里是使用的虚拟机，为了节省内存，只开了一台机器。

[grid@db1 ~]$ cat /home/grid/.bash_profile

检查oracle_sid时，发现这个节点机的SID与第二个机器一样。

看来是没有修改，于是修改正常后，检测试 asm操作正常了。

[root@db1 ~]# su - grid
[grid@db1 ~]$ echo $ORACLE_SID
+ASM1

[grid@db1 ~]$ srvctl status asm
ASM 正在 db1 上运行
