今天装完ASM时遇到的一个比较低级的问题ORA-15149: another ASM instance found running on the host

问题描述：

[oracle@localhost ~]$ export ORACLE_SID=+ASM

[oracle@localhost ~]$ export ORACLE_HOME=/u01/app/oracle/grid/11.2.0/

[oracle@localhost ~]$ sqlplus / as sysasm

SQL*Plus: Release 11.2.0.1.0 Production on 星期四 8月 1 14:35:25 2013

已连接到空闲例程。

SQL> startup

ORA-15149: another ASM instance found running on the host

有一个已经运行的ASM实例那为什么报连接到空闲实例呢？？？

查看进程：

[oracle@localhost ~]$ ps -ef | grep asm_

oracle 10179 9397 0 14:37 pts/3 00:00:00 grep asm_

oracle 16742 1 0 10:59 ? 00:00:01 asm_pmon_+ASM

oracle 20920 1 0 12:46 ? 00:00:00 asm_asmb_+ASM

确实全部启动，那是为什么呢？？？

解决办法：

细心的朋友也许已经看出了问题

那就是环境变量

[oracle@localhost ~]$ export ORACLE_HOME=/u01/app/oracle/grid/11.2.0 -----注意后面没有斜线----用惯Linux的同学习惯用tab键补全，最后面会加一条斜线--但是oracle就不认识你了

[oracle@localhost ~]$ sqlplus / as sysasm
