The "71" refers to a specific internal trace point in the Data Pump code. It almost always indicates in the dump file, object definition incompatibility , or a bug in the Data Pump client/database version.

Or:

The error is a generic "catch-all" internal error during an Oracle Data Pump import ( impdp ). It typically signifies an unhandled exception triggered by corrupted metadata, invalid system objects, or specific version incompatibilities . Common Root Causes

If the standard impdp continues to fail at the same point, try a . Instead of importing the entire dump file at once, break it down: Import the Metadata only ( CONTENT=METADATA_ONLY ). Import the Data only ( CONTENT=DATA_ONLY ).

, it typically points to a failure during the initialization phase of a Data Pump Import ( The Anatomy of the Error -- For Container Databases (CDB), ensure all PDBs

Or, check the Data Pump master table:

impdp ... PARALLEL=1

: This particular bug has been observed and documented primarily in Oracle Database 19.3.0.0 and certain 12.2 releases. Oracle recommends upgrading to at least version 20c to avoid this issue entirely. Or: The error is a generic "catch-all" internal

If internal corruption is suspected, reload the Data Pump metadata objects. For 12c and higher: @?/rdbms/admin/dpload.sql (for CDB/PDB environments, ensure PDBs are open). For older versions (10g/11g): @?/rdbms/admin/catdp.sql @?/rdbms/admin/catmetx.sql Check for Invalid Objects: Ensure all objects are valid. owner, object_name, object_type dba_objects Use code with caution. Copied to clipboard Recompile any invalid objects using the @?/rdbms/admin/utlrp.sql Verify Temporary Tablespace:

If a previous import failed, it might have left behind an "orphaned" Master Table. Query DBA_DATAPUMP_JOBS to find stalled jobs.

Direct path loads are fast but less tolerant of data anomalies. Disable it: Instead of importing the entire dump file at

There is a known Oracle bug related to KUPW$WORKER where imports fail when REMAP_TABLESPACE is used alongside certain partitioned objects.
