Controls whether a user is allowed to use the data extraction facility. Also controls the directory into which temp extract files are placed and overrides a directory path specified in the TEMP_EXTRACT_NAMEn options.
Can be set temporary for an individual connection or for the PUBLIC group. DBA authority is required to set the option. This option takes effect immediately.
If the TEMP_EXTRACT_DIRECTORY option is set to the string FORBIDDEN (case insensitive) for a user, then that user is not allowed to perform data extracts. An attempt by this user to use the data extraction facility results in the error: You do not have permission to perform Extracts.
If TEMP_EXTRACT_DIRECTORY is set to FORBIDDEN for the PUBLIC group, then no one can run data extraction.
If TEMP_EXTRACT_DIRECTORY is set to a valid directory path, temp extract files are placed in that directory, overriding a path specified in the TEMP_EXTRACT_NAMEn options.
If TEMP_EXTRACT_DIRECTORY is set to an invalid directory path, an error occurs: Files does not exist File: <invalid path>
If TEMP_EXTRACT_DIRECTORY is blank, then temp extract files are placed in directories according to their specification in TEMP_EXTRACT_NAMEn. If no path is specified as part of TEMP_EXTRACT_NAMEn, the extract files are by default placed in the server startup directory.
This option provides increased security and helps control disk management by restricting the creation of large data extraction files to the directories for which a user has write access.
