Hi...
In Unix OS, you can create multiple database instances in 1 server such as Test instance, Prod instance and Devl Instance. First of all, you have to create file called init[instance].ora for each instance.
To create this file, you can copy 1 default file init.ora to init[instance].ora:
for example: cp init.ora inittest.ora
Init.ora can be found at $ORACLE_HOME/dbs. Then rename db_name=default to db_name=test. Modify several parameters as requirement. Remember !! To create instance(s), you have to log in as Oracle owner. At unix prompt ($) type . oraenv (type test). After that, run svrmgrl and connect internal. Startup nomount;

Create database TEST ...... (see SQL User Guide & Reference)
If success, run catalogs.sql and catprocs.sql which can be found at
$ORACLE_HOME/rdbms/admin.

I don't explain this in detail, if you want to know further, please read Oracle 7Server Administrator's Guide.

I hope this will help you.
