Oracle Error Message
ORA-39189: unable to decrypt dump file set
Reason for 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.
Solution
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.
