ODBC Driver for Teradata can provide detailed trace information for DSNs associated with Teradata Database. This is referred to as DSN tracing, which differs from the higher level Driver Manager tracing, which is enabled and disabled using the ODBC Data Source Administrator.
The DSN trace file is a text file with internal information from ODBC Driver for Teradata about API calls, message transfers, and other driver actions. It is primarily intended for use by Teradata Technical Support.
Driver level tracing can be performed easily using ODBC Data Source Administrator by choosing your DSN entry and selecting the Logging Options button.
The Logging Options dialog box appears. Select the desired level of logging and the destination for the logs. Refer to the section below for more information on logging levels and steps for how to enable driver logging on Windows.
Using DSN tracing will significantly degrade performance.
