SAP B1 SDK: ODBC tracing/logging

Just wondering if anybody ever tried doing ODBC tracing or any kind of logging? I want to know more about the occasional ODBC errors (eg. -2039, -1029), so I'm wondering if it's possible to dig into it by doing ODBC tracing.

Anyway, I started by going to the server's ODBC Data Source Admin and clicked "Start Tracing Now". But somehow the trace file (SQL.LOG) is never created...

Anybody has any experience or advise about this?

Thanks
