在win2008中的oracle11g下 sqlnet.ora文件配置有感

sqlnet.ora文件如下：

# This file is actually generated by netca. But if customers choose to 
# install "Software Only", this file wont exist and without the native 
# authentication, they will not be able to connect to the database on NT.
#SQLNET.AUTHENTICATION_SERVICES = (NONE)
SQLNET.AUTHENTICATION_SERVICES = (NTS)

注意NONE和NTS的区别

这个认证方法是WINDOWS系列操作系统特有的，UNIX/LINUX不需要，或者根本不能设为NTS，

1.SQLNET.AUTHENTICATION_SERVICES =(NTS)       --基于操作系统验证

2.SQLNET.AUTHENTICATION_SERVICES =(NONE)      --基于Oraclepassword文件验证

3.SQLNET.AUTHENTICATION_SERVICES =(NONE,NTS)  --基于操作系统验证(前后顺序颠倒也一样)

4.用（NONE）数据库身份验证以后。system用户被禁止使用RMAN了。仅仅有拥有数据库最高权限的sys用户，才干登陆RMAN，并且必须是输入password的方式登陆

在实际测试中：

NONE模式
