1.问题现象

[root@asm01 ~]# su - grid
[grid@asm01 ~]$ asmcmd
Connected to an idle instance.

2.使用命令查看http://www.cndba.cn/hbhe0316/article/106564

[root@asm01 ~]# ps -ef | grep -i asm

# .bash_profile

3.判断为grid环境变量写错相关http://www.cndba.cn/hbhe0316/article/106564http://www.cndba.cn/hbhe0316/article/106564http://www.cndba.cn/hbhe0316/article/106564

[grid@asm01 ~]$ cat ~/.bash_profile 
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

# User specific environment and startup programs
PATH=$PATH:$HOME/bin
export ORACLE_SID=+ASM
export ORACLE_BASE=/u01/app/grid
export ORACLE_HOME=/u01/app/19.3.0/grid
export PATH=$ORACLE_HOME/bin:$PATH:/usr/local/bin/:.
export TEMP=/tmp
export TMP=/tmp
export TMPDIR=/tmp
umask 022
export PATH

4.执行命令再次查看

[grid@asm01 ~]$ . ~/.bash_profile 
[grid@asm01 ~]$ asmcmd lsdg
