Oracle database 11g R2 client的sqlplus无法成功连接数据库,1、数据库版本: Oracle Database 11g Enterprise Edition Release

问题环境:
1、数据库版本: Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
2、操作系统环境:Windows 7 旗舰版 64位
3、本地安装有4个Oracle 数据库软件【四个数据库软件,不是四个数据库哦】如下:
Oracle 10.2服务端软件:e:\oracle\product\10.2.0\db_1\BIN\sqlplus.exe
Oracle 11.2服务端软件:e:\oracle\product\11.2.0\db_1\BIN\sqlplus.exe
Oracle 10.2客户端软件:e:\oracle\product\11.2.0\client_1\BIN\sqlplus.exe
Oracle 11.2客户端软件:e:\oracle\product\10.2.0\client_1\BIN\sqlplus.exe

问题描述:

补充信息:
Oracle 11.2客户端sqlnet.ora文件如下:
# sqlnet.ora Network Configuration File: e:\oracle\product\11.2.0\client_1\network\admin\sqlnet.ora
# Generated by Oracle configuration tools.

# 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)
NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)
请各位湿湿们不吝赐教,,折腾了很久也没搞明白原因,纠结中。
