On Windows, open the ODBC Data Source Administrator and select the Tracing tab. To specify the path and name of the trace log file, type the path and name in the Log File Path field or click
Browse to select a log file. If no location is specified, the trace log resides in the working directory of the application you are using.
Click Select DLL in the Custom Trace DLL pane to select the DataDirect enhanced tracing library,
xxtrc
yy.dll, where
xx represents either iv (32-bit version) or dd (64-bit version), and
yy represents the driver level number, for example, ivtrc27.dll. The library is installed in the \Windows\System32 directory.
Enable tracing by clicking Start Tracing Now. Tracing continues until you disable it by clicking
Stop Tracing Now. Be sure to turn off tracing when you are finished reproducing the issue because tracing decreases the performance of your ODBC application.
