I have a RHEL4U4 server that will become an Oracle 10gR2 server in three weeks. Almost all of the documentation I have seen about installing oracle on a selinux enabled server says to turn off selinux. Only 1 document said that oracle and selinux can function together. So can oracle and selinux play nice or do I have to turn it off?
They should be able to play nice. The only place they might hit would be if there is a web interface. Oracle might also be seeking to eek out every bit of performace. SELinux can add some load between 2-20% depending on which performance test you run.

I thoht SELinux's overhead was only for the transitions and file access thereby being a small amount of this total time (est. at 7% untuned.)

The web app would be using Oracle's security with a MyWebAppUsername. Yes / No?

Could you explain this overhead and where and what is doing it, please.
I don't see where it would be any greater than 7% of the volume of transitions and file accesses (which would be different web files. And that would be an Apache overhead whether a DBMS was being used or not.

Thank you,
