步骤
下载InstantClient
Oracle官网 导航里Downloads里有Oracle Instant Client下载。
将下载的压缩包解压到一个目录里,本文解压在C:\Oracle目录里面。
创建tnsnames.ora文件
在上一步骤里创建的C:\Oracle目录里创建tnsnames.ora文件:
orcl =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.100 )(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = orcl )
)
)
配置环境变量
环境变量名 值 用途
TNS_ADMIN C:\Oracle 告诉Oracle数据库连接驱动tnsnames.ora的位置
NLS_LANG SIMPLIFIED CHINESE_CHINA.ZHS16GBK 根据自己的数据库实际情况配置
环境变量TNS_ADMIN和NLS_LANG可以用注册表配置代替详情看官方的FAQ。
Path环境变量
为了让程序能够自动找到这些InstantClient的库文件,建议将InstantClient的目录(本文中也就是C:\Oracle)加入到系统Path环境变量中。如果需要使用ODP.NET并且不是托管的版本(ODP.NET Managed Driver不需要安装任何Oracle客户端),那么这么做就是必须的。还有一点使用ODP.NET最好去下载Oracle Data Access Components (ODAC),里面同时包含InstantClient和ODP.NET,这能最大程度保证他们版本兼容。
配置PL/SQL Developer
Tools->Preferences->Oracle->Connection:
Oracle Home=C:\Oracle
OCI Library=C:\Oracle\oci.dll
如果在系统Path环境变量中添加了InstantClient的目录,那么这一步就不是必须的,PL/SQL会根据环境变量自动加载oci。
尝试连接
配置好了,,使用数据库账户密码登录测试连接。
