RE: RAC setup on linux

In random order, here's some hints:

Make sure you visit Werner's site, He has all sorts of non-RAC ideas on how to install Oracle on all sorts of RH flavors.

Beware that RH AS 2.1 is bloody old. You may have problems with it recognizing your newer hardware. Since this was just a test for us on a pair of 2.4Ghz P-IVs, I said "Screw it!" and went with RH9, which config'd our Intel D845 MB, the built-in video, and the built-in 100baseT Ethernet
(our older 3com 100baseT PCI card for the private network was recognized

Something I have not seen anywhere else (perhaps it's just my lack of understand of a "proper" network setup), but when you are creating the /etc/hosts file, do NOT alias ANY nodenames to "localhost"! The Cluster Manager will fail. For example, alias "localhost" to "" and NOT to "" (or whatever your public/domain IP address is).

If you need to change kernel settings permanently, instead of echoing values to a pseudo-file in /proc on boot, make the change in /etc/sysctl.conf

If you want to try OCFS, you *must* follow Wim's guide on OTN (can't remember the URL, but it was an OracleWorld presentation!). Without following that, 1.08 and 1.09 are deathly slow to the point of unusability. Also beware that OCFS won't work out-of-the box with RH9. I patched 1.08, following guidelines that IBM used to patch XFS for RH9. If you want the patched source, let me know.

The rest of my notes seem to mostly relate to that MetaLink doc. If you have problems, post here! There's enough of us that have tried it, that I'm sure you'll get an answer faster than Oracle Support. :)

HTH! GL! Rich

Ok spent < 1K for hardware, got 2, 2.0Ghz cpu, 1 G of ram, couple of ethernet cards(one for private heartbeat, other to put on internal network) computers and external firewire drive, doing RH AS 2.1, OCFS, etc.

gonna build a lab setup next week.

any pointers as to what gotchas would be appreciated, otherwise i'll hack my way thru it like usual :)

thanks, joe
