Oracle数据库的客户端向来以“肥大”著称，即使是它的instant client，也不算瘦。个人以为，虽然instant client发布并使用了有一段时间，但是比起它的原装产品来说，稳定性和安全性肯定有些差距。所以，我宁可自己手动extract一些有用的包，为开发所用，也不愿意去单独折腾个instant client来配置。

这里就以9i为例，在你安装完一份Oracle服务器版或Oracle客户端，在安装的目标目录会有一份完整的目录列表。有很多很多都是用不着的文件。

我们通常要用的功能也就是:

1. sqlplus命令行，imp, exp, tnsping, sqlldr (用于管理)

2. oci接口库，pro*c库，jdbc, odbc (甚或oledb)等 (用于开发)

有了这些功能，基本上可以做很多事情了。

制作原理：

1. 抽取相关目录，发布到一个新目录。

2. 生成注册表文件到这个新目录。

3. 将这个新目录复制或移动到新机器的新目录里边，就可以注册使用了。

下边是我编写的一个发布的批处理脚本oraclient_dist.bat，以及过滤文件exclude.txt

exclude.txt 文件要与oraclient_dist.bat文件位于同一目录当中

其命令格式是：

oraclient_dist.bat -from d:/oracle/ora92 -to e:/dist -inst d://ora92client

意思是从源：d:/oracle/ora92目录下边提取免安装包到目录e:/dist里头，最终安装目录定制在d:/ora92client。

最终你还可以将目标目录压缩，也就30来M，最终使用时，参见发布后生成的readme.txt文件。
