Cluster Interconnect Split Brain Testing

Filed under: 19c,RAC — mdinh @ 11:16 pm

There was a dicusssion about memory causing split brain for a 2 nodes RAC; however, the log shows otherwise.

By no means, am I a RAC expert.

For testing purpose, ethernet for cluster_interconnect was shut down.

From ocssd.trc, it does look to be caused by cluster_interconnect when comparing errors from actual vs test.

Details from Google Doc below.
