在Oracle Enterprise Manager Console登陆Oracle出现以下情况
1,独立登陆后, 然后再以System as sysdba进入数据库，正常连接.
2 登陆到Oracle Managerment Server：然后以System as sysdba进入数据库，提示ORA-01031:insufficient privileges
为什么同一用户出现此问题? 怎么解决??

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;

谢谢楼上.
后来看了相关方面的资料,登陆到Oracle Managerment Server后,然后以System 用户名连接数据库时,连接身份只能用 Normal,不能使用 Sysdba,
这样就ok连接好了数据库.
