Use the data extraction options with care.
The extraction options are set for the connection. If you set the extraction options and another user connects to the database using the same user ID, the extraction facility is also enabled for that user. Your extraction output might be overwritten by another user on the same connection.
Similarly, if another user logs in using the same user ID, the output of queries run by this user is directed to the extraction file until the option is disabled. Run extraction requests using a unique user ID.
