还必须把Administrator从设置－控制面板－管理工具－本地安全策略－本地策略－用户权利指派－作为批处理作业登陆中加入，然后再在em中输入Administrator和密码，这样就ok。

输入 Set ORACLE_SID=site1
输入 emctrl status dbconsole
从响应可以看到，里面有http://192.168.0.101:5501/em/console/aboutApplication
其中5501就是对应 site1服务的端口号
在浏览器中输入http://localhost:5501/em即可登录。

(3)输入“alter user sys identified by 新密码”，注意：新密码最好以字母开头，否则可能出现错误Ora-00988。

有了这个方法后，只要自己对oracle服务器有管理员权限，不记得密码的时候就可以随意修改密码了。
