Each time you connect to a database with tracing enabled, DataWindow Designer appends the trace output of your connection to the existing log. As a result, the log file can become very large over time, especially if you frequently enable tracing when connected to a database.
To keep the size of the log file manageable:
Do either of the following periodically:
Open the log file, clear its contents, and save the empty file.
Provided that you use the default DBTRACE.LOG or the same nondefault file the next time you connect to a database with tracing enabled, DataWindow Designer will write to this empty file.
Delete the log file.
DataWindow Designer will automatically create a new log file the next time you connect to a database with tracing enabled.
