This will enable the machine-wide ODBC tracing for all user identities.

A Log file will be used or created if none exists for every user identity 
under which a process using ODBC is running. Make sure you turn off 
this when finished to avoid large amount of log files to be created.

Are you sure that you want to turn this on?
