OCI-39412
file checksum error in dump file "dump_file_name"
- dump_file_name: The name of the dump file.
Cause
The header block for the Oracle Data Pump dump file contained a file checksum that did not match the value calculated from the header block as read from disk. This indicates that the file was tampered with or otherwise corrupted due to transmission or media failure.
Action
Transfer the dump file again from its source location. If this does not fix the issue, then contact Oracle Support.
