Recovering KMS by restoring only the KMS data file

You can restore the backed-up copy of the KMS data file kms/db/KMS_DATA.dat by regenerating the KMS_HMKF.dat and KMS_KPKF.dat files with pass phrases. So, if you have written down pass phrases for the host master key and key protection key, you can run a command to regenerate those files. The system prompts you for the pass phrase and if the pass phrase you now enter matches the pass phrase originally entered, you will be able to reset the files.
