Issue with contest and loading library. Please help!

I have probelm in SuSE Linux. LEI and Oracle client is installed without any issue. When I try create activity, I select the Oracle connection and I get “Unable to browser Oracle. Please verfiy necessary vendor libraries has been installed”.

The “contest” does not work also. It says, connection failed. But the dctest works fine. Please help to suggest what could be missing in my settings.
