If your requirement is to shutdown quickly, here is one solution
1. Find out the process id for the current session from v$process.spid. and
run "shutdown immediate"
2.. From a separate session kill all the oracle${ORACLE_SID} processes except
the process id found in step 1. This may have to be run from root, to kill
bequeath processes.

Micheal,
I understand your position and when I arrived here, I made all the
same arguments. I've been told that our legal department insists on a
cold backup, and the requirement is non-negotiable. We run full test
recoveries on all our major systems on a regular basis and we use the
hot backups to do so. None of us doubt that the hot backups are
adequate for recovery.
So I guess we're not really 24x7, we're 24x7-15 and that 15 minutes is
a sacred cow that I need to leave alone right now ...
Thanks for the input and if I was calling the shots, I wouldn't do it
this way. However, I would still need a script that would shut the
database down quickly, possibly for maintenance or hardware issues, so
I really appreciate the suggestions provided on this thread.
