今天发现asmcmd的时候是连接了空实例
[grid@RAC01 ~]$ asmcmd
Connected to an idle instance.
ASMCMD> ls
ASMCMD-8102: no connection to ASM; command requires ASM to run
ASMCMD> exit
想当然的进到asm实例中进行启动
[grid@RAC01 ~]$ sqlplus / as sysasm

通过查看发现crs_stat发现asm正常
[grid@RAC01 ~]$ crs_stat -t -v

grid 6140 6096 0 22:38 pts/2 00:00:00 grep asm
然后想到是不是环境变量配置错了
[grid@RAC01 ~]$ echo $ORACLE_SID
+ASM2
配置方法是将~/.bash_profile文件中的$ORACLE_SID=+ASM2改为$ORACLE_SID=+ASM1，然后通过source ~/.bash_profile即可（不一定是ASM1，具体的要看实际的实例名字）
发现ORACLE_SID对应的实例名是错的，故而将环境变量修改正确后，一切正常
[grid@RAC01 ~]$ sqlplus / as sysasm

网上说可以通过
alter system set INSTANCE_NUMBER=1 scope=spfile sid=’rac1′;
alter system set INSTANCE_NUMBER=2 scope=spfile sid=’rac2′;
进行修改即可
