ORA-39189: unable to decrypt dump file set

What triggered the Error:

The dump file set could not be decrypted. The reason could be either that an invalid password was entered, or that, when using transparent decryption, the database external security device was not open.

What should we do to fix it:

If password-based import was enabled for this dump file set, then supply the correct password. If transparent import was enabled for this dump file set, then ensure that the database external security device is open.
