Environment variable ORACLE_UNQNAME not defined. Please set ORACLE_UNQNAME to database unique name.

 启动em 报错如下：

[oracle@server253 bin]$ emctl start dbconsole
Environment variable ORACLE_UNQNAME not defined. Please set ORACLE_UNQNAME to database unique name.

解决方法：

oracle的环境变量UNQNAME没设或设置不正确

export ORACLE_UNQNAME=benguo（换上你自己的）export这个参数和em企业管理器有关。

[oracle@server253 bin]$ vim /home/oracle/.bash_profile

ORACLE_SID=benguo
# .bash_profile

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