I am using Report Builder 3.0, loaded from a server running SQL Server 2008. The software is being used within Internet Explorer 8.0. I am trying to connect with an Oracle 9i database through Oracle 9i client, but have not been successful. My connection is to a server named sftr403.devl, defined in my tnsnames.ora file, When I test the connection using the build window within the connection properties window, I get the message that test connection succeeded. However, when I try to connect directly from the connection properties window, I get the error message "Unable to connect to the data source. Please verify the connection properties and credentials". Why is the same connection only working in one place and not the other?
