解决方案

1. 从 http://www.oracle.com/technetwork/database/features/instant-client/index-097480.html 下载Oracle Client Package。 我下载的是Instant Client for Microsoft Windows (32-bit) 【instantclient-basiclite-nt-11.2.0.2.0.zip -》（instantclient_12_1.zip）】 

2. 将 instantclient-basiclite-nt-11.2.0.2.0.zip 解压至 F:\instantclient_12_1 所在目录为：F:\instantclient_12_1

3. 启动PL/SQL Developer ，点击“取消”不要登录，菜单 --> Tools --> Perferences --> Connection 修改 Oracle_Home 和 OCI Library 的配置：
    OracleHome: D:\app\Administrator\product\11.2.0\dbhome_1  （orcle 所在的安装目录）
    OCI library: F:\instantclient_12_1\oci.dll  （解压的目录）

4.apply -》OK -》重启
