pl/sql连接远程Oracle

连接工具：pl/sql developer

连接远程服务器的Oracle时需要修改配置文件。若本地没有oracle，则在安装oracle的机器下找到名称为instantclient_11_2的文件夹，拷贝到本地。

找到该文件夹下面的文件D:\Program Files (x86)\plsqlconfigfile\instantclient_11_2\NETWORK\ADMIN\tnsnames.ora

修改其中的配置信息，修改后的文件内容如下：

# tnsnames.ora Network Configuration File: D:\Oracle\product\11.2.0\dbhome_1\network\admin\tnsnames.ora

# Generated by Oracle configuration tools.

打开pl/sql，tools---preference---connection

将oracle home的路径改为D:\Program Files (x86)\plsqlconfigfile\instantclient_11_2

将oracle oci library的路径改为D:\Program Files (x86)\plsqlconfigfile\instantclient_11_2\oci.dll

重新启动pl/sql， 输入用户名密码，即可登陆进远程服务器的数据库中
