I guess I left things a little ambiguous. Here are the details:

1) My goal is to make a carbon copy of my company's current databse setup
on a new host for testing purposes. The current database setup has two
databases on one host - one database holds the 'data'- this database has 5
schemas - and the other is used to keep track of work requests.

2) I using Oracle8i (8.1.7). My OS is Compaq Tru64 UNIX

3) I want to keep the same ORACLE_HOME - this is what was done in the
databases I am making a copy of.

I have already installed Oracle and I set up the 'data' database. After I
had set it up I realized the 'work request' database needed to be on the
same host. I am now unsure how to create the second database on this
host.
