To most effectively troubleshoot a database connection, set the configuration variable MS_SESSION_DEBUG.

If you set this configuration variable, session debug will start prior to server.ma loading. That is, debug messages will start as soon as the database components load.

If you set MS_SESSION_DEBUG to 1, you will get debug information from server.ma and the corresponding DLL (ORACLE, ODBC, OLEDB). If you set MS_SESSION_DEBUG to 0 you will only get output from the DLL.
