Answer 1

It's got nothing to do with who he's running the installer as (though he should indeed run it as the oracle user, of course).
It's got everything to do with the fact that a lot of distros these days automount their CDs with the noexec switch set. Meaning that no-one apart from root is allowed to execute programs from the mounted media. Centos 5 does it, so RHEL5 would do it too. OpenSuse10.3 doesn't do it; Fedora 8 does; Debian 4 does.
If your distro uses an old-fashioned fstab (Debian 4 does, for example), you could edit that and stick an explicit 'exec' switch in as one of the mount options (plain old "user", commonly specified, implies "noexec").
But RHEL5 and Fedora 8, for example, use a new udev-magic way of dynamically mounting removable media, so there's nothing listed in /etc/fstab until after a cd or dvd has been automounted... and by that stage, it's too late to edit what the mount options should be!
The fix for these sorts of distros is to become root and manually unmount any Oracle CDs or DVDs that have been automounted. You can then simply re-mount them by issuing a command such as
mount -o loop /dev/cdrom /media...and, because this manual mount doesn't include explicit noexec switches, you'll find that if you now become the oracle user, you'll be allowed to execute the runInstaller program normally.
