Forgot to mention:

Oracle Linux 5.x using the UEK is vastly superior to RHEL4 or RHEL5. I know you want to use a single OS verison, but by going RHEL4 you are crippling your performance.

Currently no idea of the certification of 12c. I know someone on the beta program who is running it on OL5.x. Not sure yet if it is going to be certified on RHEL6/OL6. I hope so. It would not surprise me if it never gets certified on RHEL4/OL4. Oracle don't make habit of certifying against really old OS versions. You'll notice that 11g is only certified on RHEL/OL4 and RHEL/OL5. No backwards certification on RHEL3. If 12c is certified on RHEL/OL5 and RHEL/OL6, I can't imagine Oracle would waste the time and money to certify on RHEL/OL4.

Once again, just my opinions, not facts.
