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 220.127.116.11.0 - Production Version 18.104.22.168.0 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 22.214.171.124.0 - 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?
