I need to import some sample dump file for educational and testing purposes. I've found the next dump file and tried to import it using:

imp testuser/oracle file=/home/oracle/PurchaseOrders.dmp

Connected to: Oracle Database 18c Enterprise Edition Release 18.0.0.0.0 - Production
Version 18.3.0.0.0

IMP-00037: Character set marker unknown
IMP-00000: Import terminated unsuccessfully

Also, I've tried to import it using:

impdp testuser/oracle directory=dmp_dir dumpfile=PurchaseOrders.dmp full=y;

Connected to: Oracle Database 18c Enterprise Edition Release 18.0.0.0.0 - Production
ORA-39001: invalid argument value
ORA-39000: bad dump file specification
ORA-31619: invalid dump file "/home/oracle/PurchaseOrders.dmp"

How could I import this dump into my test Oracle DB?

Thank you!

  • from error logs you have posted, you need to get a valid dump file because the one you seems corrupted.

  • This dump could be viewed by text file viewer/reader. So, maybe someone could say what is wrong with it. Or, maybe there's another tool could be used to import it. I'm still looking for correct sample dump file.

  • And I've posted two error logs and they are different. impdp says it is invalid, but imp says about Character set marker. These two are different commands.

    Just clone or download whole folder db_samples_schema(8 Schemas) and follow the instructions outlined in first page Metadata is created with sql scripts inside corresponding schemas.If you wanted to install only OE schema,download order_entry folder and start with oe_main.sql in order_entry folder(comment out anything related to HR schema) but before starting the script run the perl command that replaces __SUB__CWD__ with
