如上图所示，scott用户的确不存在。

② 由于操作系统是Linux，则用xshell登录Linux界面，切换到oracle用户，如下图所示，找到如下目录，看是否存在scott.sql文件：

/home/oracle/product/ora11g/rdbms/admin -- 该路径视自己的实际路径为准 

如果存在，则以sys用户登录数据库，并执行如下语句：

如果不存在，则在/home/oracle/product/ora11g/rdbms/admin下创建scott.sql文件，并保存如下代码：

然后再执行：

即可。

到此，scott添加成功。

如果需要修改scott用户密码，则执行如下语句：

alter user scott identified by 123456;

怎么样？是不是很简单呢？
