Oracle 11g 客户端配置

Windows下Oracle 11G - ODAC 11.2 Release 3 安装配置

 

1. 下载Oracle 11G客户端工具：ODAC 11.2 Release 3 (11.2.0.2.1) with Oracle Developer Tools for Visual Studio，已包含的组件：
   - Oracle Developer Tools for Visual Studio 11.2.0.2.0
   - Oracle Data Provider for .NET 4 11.2.0.2.0
   - Oracle Data Provider for .NET 2.0 11.2.0.2.0
   - Oracle Providers for ASP.NET 4 11.2.0.2.0
   - Oracle Providers for ASP.NET 2.0 11.2.0.2.0
   - Oracle Database Extensions for .NET 4 11.2.0.2.0 -- for upgrade only
   - Oracle Database Extensions for .NET 2.0 11.2.0.2.0 -- for upgrade only
   - Oracle Provider for OLE DB 11.2.0.2.0
   - Oracle Objects for OLE 11.2.0.2.0
   - Oracle Services for Microsoft Transaction Server 11.2.0.2.0
   - Oracle ODBC Driver 11.2.0.2.0
   - Oracle SQL*Plus 11.2.0.2.0
   - Oracle Instant Client 11.2.0.2.0
2. 解压到临时文件夹，再双击setup.exe执行安装，假设安装在：D:\app\wiflish\product\11.2.0\client_1目录下，安装过程略；
3. 设定环境变量：
   ORACLE_HOME=D:\app\wiflish\product\11.2.0\client_1
   TNS_ADMIN=D:\app\wiflish\product\11.2.0\client_1
   NLS_LANG=SIMPLIFIED CHINESE_CHINA.AL32UTF8，注：语言编码要与Oracle服务器设置的一致，可以通过 select userenv('language') from dual; 查询服务器的语言编码；
4. 配置tnsnames.ora文件，在D:\app\wiflish\product\11.2.0\client_1\Network\Admin\目录下，新建tnsnames.ora文件，内容如下：
   ORCL =
   (DESCRIPTION =
   (ADDRESS_LIST =
   (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.3)(PORT = 1521))
   )
   (CONNECT_DATA =
   (SID = ORCL)
   (SERVER = DEDICATED)
   )
   )
   其中：第一个ORCL为数据库实例名；192.168.1.3为Oracle数据库服务器地址；SID = ORCL为Oracle数据库服务器中安装是的SID。
5. 使用客户端连接工具如PLSQL Developer 连接测试，输入用户名和密码，连接成功；
6. Oracle的Instant Client的即时客户端连接工具的配置方式类似，将配置目录修改为Instant Client的解压目录；
