Oracle 11g EM无法启动

内容简介：Oracle 11g EM无法启动

〇、错误

使用dbca安装数据库，虽然中间勾选了EM选项，却发现并没有随着安装的完成而启动，以下就是整个排错过程。

一、排错

1.1、检查hosts文件

发现hosts文件中没有x.x.x.x hostname这一行，将改行数据加入后保存文件。比如：

192.168.224.150 dbsrv.test.com dbsrv

上段代码中，第一段为本机静态地址，第二段为hostname完整形式，第三段为hostname简单形式。

1.2、检查ORACLE_UNQNAME环境变量

执行如下命令查看结果：

echo $ORACLE_UNQNAME

发现并未有返回值，说明该变量没有设置，执行：

export ORACLE_UNQNAME=orcl

其中orcl为数据库的SID。

也可以将上面的语句写入到~/.bash_profile文件中使每次登陆都自动生效。

1.3、重新配置EM

执行：

emca -config dbcontrol db -repos recreate

根据提示填入内容。
