Oracle 9.0.1.4 RAC problem

Hi,

We are using Oracle 9.0.1.4 RAC with 2 instances now. However, we often encounter a RAC bug "waiting for clusterware split-brain resolution". Can anyone explain what it does mean? Does Oracle 9.2.0.X fix this issue completely?

Thanks for any comments.

This is serious.

Both nodes of the cluster think they are primary.

This is probably a communications problem between nodes. If it was Serviceguard, I'd say check the heartbeat lan.

I don't think an upgrade will help.

Hello,

Most likely Oracle is configured with very short timeouts. The default value is 5 minutes.
