If you are unable to resolve the issue using the above steps, you may want to engage Oracle Support or a certified Oracle professional for further assistance. They can help you:
Issues with importing table statistics, especially on partitioned tables, can trigger this internal logic error. impdp user/password directory=DIR dumpfile=data
While the ORA-39126 message itself is often high-level, it is almost always accompanied by a second, more descriptive error in the log or trace file, such as ORA-01403: no data found ORA-06502: PL/SQL: numeric or value error Common Root Causes Corrupted Data Pump Metadata: If the internal packages used by Data Pump (like DBMS_METADATA

impdp system/password DIRECTORY=dpump_dir DUMPFILE=full.dmp FULL=Y EXCLUDE=SCHEMA:"IN ('SYSTEM','SYSMAN','SYS','AUDSYS','GSMADMIN_INTERNAL')" Use code with caution. Step 2: Validate Data Pump Components
The internal Data Pump packages ( DBMS_DATAPUMP , KUPW$WORKER ) might be invalid, or a recent PSU/RU (Patch Set Update/Release Update) update was improperly applied, leaving the Data Pump dictionary in an inconsistent state. If patching is impossible or the error is
If patching is impossible or the error is not version-specific, check the environment:
SELECT job_name, state FROM dba_datapump_jobs; -- If orphaned jobs exist, drop their corresponding master tables: DROP TABLE username.job_name; Use code with caution. Long-Term Prevention
: Keep your Oracle database on the latest Release Update (PSU/RU). The bug described in this article is fixed in later 19c PSUs and 20c+. A regular patching cycle is the most effective prevention.
