When importing data using the IMPDP data pump in Oracle, if you have already created a user before importing, you will be prompted with an error: "ORA-31684: Object type already exists", such as:

In fact, this problem is not serious, you can not create a user, import when you specify a Super user import:

impdp system/123456@ORCLDIRECTORY=DUMP_EXPDUMPFILE=EXPDATA.DMP  remap_schema=SOURCE_USER:DEST_USER

This will not cause a ORA-31684 error, and the user "Dest_user" of the desired target database will be created automatically.
