Tracy:
This is just silly.  If you're working for a company that can buy a
separate server for every single installation of oracle, that company
is making too much money.

Any DBA that EVER crashed a db due to "administering db in an
incorrect manner" ought to have their sorry butts fired.

I've had occasions where, for a variety of vendor-related reasons,
I've administered up to 5 different versions.  It's a reality of our
business.   I've never experienced a problem runing multiple versions.
 I'm currently running 5 databases with 7.3.4,
5 databases with 8.1.7.4, and 4 databases with 9.2.0.4, all on the
same server, and all are running just fine.

Just my .02, but you should stick to your guns.
