Just a quick post to create database with minimum parameters.
Note: for the control_files parameter to be updated, you must create spfile from pfile.

Many years ago, I had learned about drop database.
https://mdinh.wordpress.com/?s=drop+database
It does not do a complete job for cleanup.
What I did not know then which I now know, it does drop spfile as spfile is considered as part of the database, may be because it can get backup from RMAN just like the database?
