Before you begin
Ensure that you have defined a singleton service using the Administration Console. See Define a new singleton service.
A singleton service is a service running on a Managed Server that is available on only one member of a cluster at a time. WebLogic Server allows you to automatically monitor and migrate singleton services from one server instance to another.
To configure the migration behavior of a singleton service:
The Summary of Clusters table displays all the clusters defined in the domain.
The class specified in Class Name must implement the singleton service interface in order to function as a migratable singleton service. See Service-Level Migration.
After you finish
The singleton service created using these procedures uses the default behavior for determining the list of candidate servers for migration. The default is to iterate through all of the servers in the cluster. To configure the list of candidate servers and other aspects of automatic server migration, see Configure server migration in a cluster.
