Configure server migration in a cluster

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 Administering Node Manager for Oracle WebLogic Server.

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 generic data sources.


To configure server migration in a cluster:

  1. In the left pane of the Console, expand Environment and select Clusters.
  2. Select the name of a cluster for which you want to configure migration.
  3. Click Migration.
  4. In the Available field, select the machine to which to allow migration and click the right arrow. Repeat this step for each machine.
  5. Select the data source to be used for automatic migration or click New to create a new data source.
  6. Click Save.
