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.
