Without the clamav-milter for sendmail (activated below), this is useless.

Unless using linux software raid, this is useless.

Unless your hardware changes frequently, you can safely stop this.

I doubt you need this.

No point in an oracle box.

There are far too may services running.
If this is just for Oracle, then get rid of all those marked above, unless
you explicitly use them.

You wont gain that much RAM back, but its a start before you invest in more.
I still think connecting from another workstation, and running the
oracle/fedora box in runlevel 3 is better.
