Hi. I'm a Unix Administrator, mathematics enthusiast, and amateur philosopher. This is where I rant about that which upsets me, laugh about that which amuses me, and jabber about that which holds my interest most: Unix.

Ka-blooey said the cluster.

Spent a bit building out an Oracle RHCS cluster for a customer. So Oracle Engineers install Oracle 11g, I configure the RHCS cluster, and I notify the Account Manager that all that's left are a few tests.

Simple tests. Like, "clusvcadm -R oracle-svc". Ok, passed that. "clusvcadm -r oracle-svc -m db2". Passed that one, too. Now to the fun tests...

sync && sleep 10 && sync && ifdown bond0

Watching rgmanager logs...looks like...yup, it detected the failure, fenced db1, and started bringing up oracle-svc on the local machine. Excellent!

The cluster is looking good. Now to push it a bit more.

"umount -f /u02"

Oh dear God. That was a mess. I learned a few things.

1) Oracle Engineers know some amazing 4 letter words.
2) Oracle software isn't as robust ( least on RHCS) as I personally would like it to be.
3) RAC is the preferred cluster solution for Oracle for a very good reason.
