Oracle RAC has both ha (high availiablity) and lb (loadbalance). And the basis of its highly available Failover (fail over)  It means that the failure of any node in the cluster will not affect the user's use, the user connected to the failed node

Oracle RAC also has HA (High Availiablity) and LB (LoadBalance), and its High availability is based onFailover (Failover)It means that the failure of any node in the cluster will not affect the user's use, and the user connected to the faulty node
