But you still need to do a cold copy of the database files, right?

Actually, the belief was correct for some versions of oracle and some platforms. Case
in point was
Oracle 7 on an HP server. The source must be down in order to bring up the clone and
recreate the
control file.

Ron,
When you clone a database, you start with :
1) changing db_name in the init.ora file and most paths
2) defining a new ORACLE_SID and renaming init.ora accordingly
3) starting the instance without mounting it - your init.ora file is
opened and read.
Where do you want anything to interact (badly) with an existing
database?
You have allocated some shared memory, have started a few processes and
read a file. Big deal.
Your belief was wrong.
