Hello

I am new to this RAC node eviction issue.

We have a server that hosts an Exadata machine with a RAC 6 nodes in a 12cR2 Oracle release. From time to time a node is evicted (node 6 for example reboots) and I am still unable to find the root cause of this node eviction. For example the last reboot of node 6 occured on 24/04/2020 at 10H:22:38

I have extracted information about top wait events and TOP SQL arround that period which I can share with you if you can help

In any case, I would like to know the steps to follow in order to find the exact root cause of this node reboot

Howdy, Stranger!
