Cause: 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.Action: Ask the database administrator to perform the operation or grant the required privileges. For Trusted Oracle users getting this error although granted the appropriate privilege at a higher label, ask the database administrator to regrant the privilege at the appropriate label.权限不够 ？
分别用system和sys用户以sysdba用户登录实验过 =========================================== 这两个用户启动成功还是不成功？如果 system 和 sys 用户启动成功，而 windows 用户启动不成功，则看看 windows 用户是不是属于 ORA_DBA 组。
