We have a C++ application which uses oci calls to connect to Oracle database. The application is built with 9i libraries. When we connect we try 10gR2 client and 10gR2 server combination, we are not able to connect to the db. We are able to connect to the db via sqlplus but not via our application.
What is the change from 9i to 10gR2 that is causing this problem. Do I need to rebuild the product with 10gR2i headers and libraries?
The error message in our log file is: oci.so: invalid mode for dlopen(): Invalid argument
