如果不想自己写,可以通过 Net Manager 来配置.
以下配置文件中的 localhost 改为 ip 地址,否则,远程不能访问.

3.停止和启动服务
先停止以下服务,然后再启动.

|
OracleOraDb11g_homeTNSListenerOracleService* |
客户端配置
1.下载 ODAC 压缩包.
2.解压下载的 ODAC 压缩包.
3.执行安装命令
示例:
|
1
|
install.bat all D:\Program\ODAC\12040x64 OracleHome true |
4.添加环境变量
ORACLE_HOME : 是 ODAC 安装的目录.
TNS_ADMIN : 是文件 tnsnames.ora 所在的目录,一般为 ODAC 安装目录下的 network\admin 中.
注: TNS_ADMIN 可以不用添加,直接将 tnsnames.ora 文件复制到 ODAC 安装目录下即可
将 %ORACLE_HOME% 添加到 PATH 环境变量中.
5.配置 TNS
在配置文件 tnsnames.ora 中加入

说明:
<db-host> : 数据库电脑的IP或者是计算机名
<db-name> : 数据库TNS配置的名称
