你的客户端是不是也装了oracle呀 如果也装了oracle，在联接数据库时要加上联接字符串connect sys/密码@connstr as sysdba
ORA-01031 insufficient privileges 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. Action: Ask the database administrator to perform the operation or grant the required privileges. 是报你的权限不够。可能是调用一个表没有权限，给足权限就好了！ grant 权限
修改sqlnet.ora文件
SQLNET.AUTHENTICATION_SERVICES= (NTS)
注释掉

我的连接格式是对的 呀
好像有一次我在客户端的oem中启动服务器的数据库是从关闭状态直接打开
到装载时出了点红色的错误提示 我没看清 就点打开了 再以后就出问题了
