Omotion is a utility that is distributed as part of Oracle RAC One Node. The Omotion utility allows you to move the Oracle RAC One Node instance from one node to another in the cluster. There are several reasons you may want to move the instance such as the node is overloaded so you need to balance the workload by moving the instance, or you need to do some operating system maintenance on the node however you want to eliminate the outage for application users by moving the instance to another node in the cluster.
