1. 下载
首先下载occi所需要的库：[url=http://www.oracle.com/technology/tech/oci/occi/occidownloads.html]http://www.oracle.com/technology/tech/oci/occi/occidownloads.html
下载linux版本。
然后下载occi所需要的头文件：即instantclient-sdk
http://download.oracle.com/otn/l ... inux32-11.2.0.1.zip
解压后里面有所需要的头文件，主要是occi.h
2. 将occi所需库拷贝到/usr/local/lib/
然后：
ln -s libocci.so libocci.so.11.1
ln -s libclntsh.so.11.1 libclntsh.so
3.
示例，根据互联网修改的
