Symptoms

DataPump Import (IMPDP) fails with the following errors:

ORA-39002: invalid operation
ORA-31694: master table "" failed to load/unload
ORA-31640: unable to open dump file "" for read
ORA-19505: failed to identify file ""
ORA-27046: file size is not a multiple of logical block size

Cause

The exported dump file is corrupt.

Solution

If the dump file came from a different system, then check if a binary transfer has taken place to transfer it to the current system. Also check the file size and if possible the checksum of the dump file.

If the problem persists:

• recreate the dump file by restarting the EXPDP process and make sure EXPDP completes without errors
• verify that the directory pointed to by the DIRECTORY parameter can be read from and written to without any problems. This can e.g. be done by performing an EXPDP and IMPDP operation or by using the UTL_FILE PL/SQL routine to read from and write to a file in this directory
