Metalink Note:216912.1 describes how to do ODBC and sql*net tracing. An interesting comment: "ODBC tracing may work intermittantly. If this is the case you can try reinstalling Microsoft's Data Acces Components (MDAC) from
http://msdn.microsoft.com/library/default.asp?url=/downloads/list/dataaccess.asp  and the reboot the computer. "
