oracle禁用操作系统认证方式登陆

WINDWOS 平台:

　　到oracle的安装目录下 cd %ORACLE_Home%/network/admin目录下,找到一个sqlnet.ora的文件(若没有，可以手工创建)

　　编辑以下内容:

　　# 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 = (NTS)

　　----

　　注: 若有此文件，默认的是 SQLNET.AUTHENTICATION_SERVICES = (NTS), 此时,只要在其前面增加一个#,

　　注释掉此行,就可以了

      LINUX平台:

　　到cd $ORACLE_HOME/network/admin目录下:

　　查看是否有sqlnet.ora文件，若没有手工创建,

　　[oracle@rh4-db2 admin]$ more sqlnet.ora

　　# sqlnet.ora Network Configuration File: /ora10g/product/10.2.0/network/admin/sqlnet.ora

　　# Generated by Oracle configuration tools.

　　NAMES.DIRECTORY_PATH= (TNSNAMES)

　　sqlnet.authentication_services=(none)
