My 18.104.22.168 install on Red Hat Linux 7.1 did not go well.
For one thing I kept having a corrupt data dictionary which
kept the Enterprise Manager from working.
The Oracle Support desk insists that the salesman was wrong
and this is not a valid (certified) software combination.
They are sending me a copy of Oracle 9.01 which is supposedly
a valid copy for Red Hat 7.1
You'll find some good links there for your project.
And as a further aside...read everything you can get your hands on and do as much upfront as you can before starting the installation. It took me 5 days to get a process down properly to get a clean install of both Linux and Oracle.
