ORACLE求助! 急盼高手回复!

我查了错误帮助,好象是权限问题,具体内容如下(我英文不好,你自己看吧):
An attempt was made to change the current username or password without the appropriate privilege. This error also occurs if attempting to install a database without the necessary operating system privileges. When Trusted Oracle is configure in DBMS MAC, this error may occur if the user was granted the necessary privilege at a higher label than the current login.

对了 登陆dba好象是 conn 用户名/密码 as sysdba;
