What’s the difference between scan listener and VIP listener?
Connection Establishment: Client sends request to one of VIP Listeners mentioned in client connection string, if failed then client will send request on another VIP address until the connection is successful. So client sending requests directly to VIP listeners specific/bound to VIP on each node.
