Connecting to oracle database using C++, the basics

Question

i have a question about the theory here, i'm just starting a project which is based on C++ applications integrating with oracle DB's, i've came to two choices, OCCI, and OCI

the OCCI is said to be aimed at C++ environment, but i was wondering, if it would be any good to use the OCI libraries from my C++ app since it is said to have better performance, or would i run into compatibility issues ?

thanks in advance :)

You can have a look at OTL it's a wrapper above the OCI or OCCI (not sure) will give some templates and samples to start with oracle connection in c++.

In my case, my company have about a thousand stores.

To connect Oracle / Oracle thru an MS C++ multi-thread service we perform the following tests on each thread:

Validate DNS (gethostbyname)
Try to open SCManager of the store (OpenSCManager)
Verify if Oracle Service exists on the store (OpenService)
Verify if Oracle Service is running (QueryServiceStatus)

After all, we try to connect (ado->Open)

This procedures minimize possible errors like 0xE06D7363 when connecting to a external server.
