Ron,
I believe it was a misinterpretation of Oracle's documentation. I regret to
say that I've been there, done that only to learn better later. The problem is that
we confuse the relationship between the Oracle SID and the DB_NAME. It is totally
possible to start an instance with a SID of DEVL where the DB_NAME in the init.ora
file is "PROD' on the same server. I agree with you that you want to change the
DB_NAME as quickly as possible before letting everyone in, but it does work. All of
the OS processes are related to each other by the SID and the db_files by the DB_NAME.

Whenever we clone a database on the same server we have always had the
understanding that the original database must be down until the new
database is renamed by running the control file script.
I am going through the Oracle Recovery 101 book in an effort to
understand RMAN and one chapters in the book is cloning a database on
the same server. I just went through the steps to create a clone of a
hot database. I created the new database on the same server with a new
name while the original database was up and running. I had no problems.
Was our belief that the original database had to be down, incorrect, or
was this just a restriction of older version like 7.3.4?
Thanks!
