You can restrict Easysoft JDBC-ODBC Bridge to a single ODBC data source.
To do this, add a new string value entry called DSN to the:
HKEY_LOCAL_MACHINE\SOFTWARE\Easysoft JDBC-ODBC Bridge\Configuration\System\Settings
registry subkey by right-clicking and then choosing New > String Value.
Set the subkey value to the name of the target ODBC data source.
Attempts to connect to another data source result in an exception being thrown.
