What happens on public network adapter failure?
實在不能確認最初的出處了，我看到的最初的是在上文中的。
Prior to 10.2.0.3
What happens on public network adapter failure? This list does not represent the exact sequence of events.
The VIP resource is relocated to another node in the cluster
The Listener resource is taken offline
The RAC database instance is taken offline
The ASM instance, if present, is taken offline
The ASM instance, if present, and RAC database instances deregister with the other listeners in the cluster
Post 10.2.0.3 patchset
What happens on public network adapter failure? This list does not represent the exact sequence of events.
The VIP resource is relocated to another node in the cluster
The Listener resource is taken offline
The RAC database instance stays up and blocked for general operations
The ASM instance, if present, stays up
The ASM instance, if present, and RAC database instances deregister with the other listeners in the cluster
What happens when the Public adapter comes back?
The VIP will be relocated back to its host node, this will happen the next time Oracle Clusterware checks the instance.
This check is carried out, by default, every 600 seconds so this is the maximum amount of time that could pass before
the relocate is triggered.
The VIP can manually be relocated back to its home node using the srvctl start nodeapps –n <nodename> command
拔掉公網網線，對於10.2.0.3之後，vip切換，本地listener down。
插回網線，vip會切回本地（大概600秒之後），lisntener沒提是不是會啓動。
