When importing with Data Pump, errors occur as follows due to the creation of the relevant dump file with the traditional export (exp) command.
ORA-39001: invalid argument value
ORA-39000: bad dump file specification
ORA-39143: dump file "/u01/backup/export/orcl.dmp" may be an original export dump file
To avoid the error, the import operation should be performed using the traditional import command. The problem will not occur when importing with a command similar to the following.
imp <user>/<password> file=orcl.dmp ignore=y full=y indexes=n statistics=none constraints=n log=orcl_imp.log grants=n
