For questions about the Oracle Data Pump Import (invoked with the impdp 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
impdp uses the Oracle DataPump framework to import proprietary dump files created by the
expdp commands to restore data from an export. See the datapump page for more information on DataPump.
