实验：对OCI测试程序产生回包数据的读取
前言
尝试分析OCI测试程序产生回包流的读取。
用调试器带上OCI测试程序跑，跟到OCI dll中，数据分隔已经搞清了。按照数据分隔往出读，含义也能猜个大概。
但是OCI的回包流格式和sqldeveloper.exe的回包流格式不一样。
sqldeveloper.exe是java写的，不知道他调用的本地函数是哪个。只能靠猜，不靠谱。
看sqldeveloper和oracle数据库的包交互，好像磋商了通讯协议的版本。产生的回包，格式比OCI的紧凑（size小）。
OCI应该也能干这事，初学，没有深入实验了。
做这个实验，为以后抓包和分析包的实验留一个测试工程。稍加改动就可以做别的实验。
测试工程
src_oci_tns_package_reader.7z
编译环境 : vs2017 vc++ console on win10x64
功能：
进行抓包，根据OCI dll读取回包的反汇编实现为依据，尝试在测试程序中模拟读取并显示。
经过读取后，OCI回包的2进制流，已经变成了可以猜测理解的数据。
运行效果
