ArcSDE For DB2的开发模式

以前就知道ArcSDE for Oracle是使用OCI(Oracle Call Interface)开发出来的(已经与esri美国工程师确认过)。

但是一直不知道ArcSDE for DB2是拿DB2哪个模式开发的，从ArcSDE的动态库和执行文件中可以看出一些端倪。

如查看ArcSDE的服务进程文件所调用的DB2的动态库：

从上面的数据得出，SDE的动态库后台使用了8个DB2的动态库，感觉是拿DB2的cli开发的，然后查看了自己使用cli开发的应用程序，看看使用了哪些DB2的动态库。

跟ArcSDE所使用的DB2的动态库是一样的。所以应该是拿DB2的cli开发的。
