Thank you! I thought I was going to have to quit drinking. Or drink

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 isopened 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.
