the NTS option makes the Oracle client attempt to use your current Windows domain credentials to authenticate you with the oracle server. This could fail for a couple of reasons:

FIX: IN DB SERVER
找到安装目录:E:/oracle/product/10.2.0/db_1/NETWORK/ADMIN 打开sqlnet.ora
option 1: 在里面找到 SQLNET.AUTHENTICATION_SERVICES= (NTS)
将其更改为: SQLNET.AUTHENTICATION_SERVICES= (BEQ,NONE)
option 2:或者注释掉:#SQLNET.AUTHENTICATION_SERVICES= (NTS)
在windows中,是通过sqlnet.ora这个文件来实现验证机制控制的,当你装完数据库并用netca创建了监听,就会生成这个文件,通常默认是以下内容:
# This file is actually generated by netca. But if customers choose to
# install "Software Only", this file won‘t exist and without the native
# authentication, they will not be able to connect to the database on NT.
SQLNET.AUTHENTICATION_SERVICES = (NTS)
也就是说,默认就是采用操作系统验证的,也许Oracle认为,拥有了SA权限,就拥有了系统最高权限,所以数据库DBA的sys用户也无需再验证密码了
如果设置成(NONE),就表示采用数据库身份验证,还可以设置成(NONE,NTS),其实这样设也没有意义了,只要括号中有NTS,就会采用操作系统验证,NONE就没有用了
这里要指出一点,有些文章中说还可以设置成(ALL),但我设计测试下来,如果设置成(ALL),会提示ERROR:
C:\Documents and Settings\Administrator>sqlplus / as sysdba
