Before you begin
Ensure that you have created a machine and have assigned managed servers to it. For more information on configuring a machine, see Create and configure machines. For more information on assigning servers to a machine, see Assign server instances to machines.
Ensure that you have configured Node Manager and that you have enabled automatic migration for at least one clustered server. For more information, see Overview of Node Manager Configuration.
Also ensure that you have configured a data source that can be used by each migratable server to restore session data after being restarted on another machine. You must configure each migratable server in the cluster with this data source. For more information on configuring a data source, see Configure JDBC data sources.
