For questions about the Oracle Data Pump export (invoked with the expdp command). Use together with the [oracle] tag, and include the appropriate version tag, such as [oracle-12c]. If the question applies to both the impdp and expdp commands, do not use this tag; use [datapump] tag instead.
The command line utility expdp uses the Oracle DataPump framework to export proprietary dump files of database data. The ouput files can be imported by the impdp commands to import that data into the same or a different database. See the datapump page for more information on DataPump.
