I hava an export file but while export operation an error was raised and the export finished with errors. However, until the problem, a lot of tables were exported. I can see from logfile.

Now, is there any way to read this broken dmp file?

When I want to import, the error says

ORA-39246: cannot locate master table within provided dump files
ORA-39059: dump file set is incomplete

Is there anything like DUL for this?

DBRECOVER.com can provide a service for imcomplete or corrupted exp dmp file.

DBRECOVER Recovery Options

For Oracle incidents, start with the DBRECOVER for Oracle trial to verify table visibility, row previews, and export readiness on copied datafiles. For MySQL and InnoDB incidents, DBRECOVER for MySQL is free software and can inspect.ibd files, ibdata1, and database directories locally.

When the case is urgent, preserve the original files first, work from copies, and contact paid emergency support with the database version, platform, error messages, file list, and recovery objective.
