oracle11g error ORA-39002, ORA-39070, ORA-39087 Scenario Description

When using data pump to import data, Report ORA-39002, ORA-39070, ORA-39087 three errors.

SQL statement used when importing data: IMPDP ' sys/123@test as Sysdba ' dumpfile=test.dmp logfile=test.log full=y directory=test

Solution

The SQL statement used to modify the guide data is: IMPDP ' sys/123@test as Sysdba ' directory=test dumpfile=test.dmp logfile=test.log full=y
Why is this so modified? My personal understanding is that Oracle finds the data file by first locating the directory we created (the logical directory in the database), and then looking for the physical directory on the local disk based on directory, so we need to put our directory in the front.
