Before you begin
Singleton services can only be migrated automatically within a cluster. Ensure that you have created and configured a cluster and its member servers.
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 lets you automatically monitor and migrate singleton services from one server to another.
To define a new singleton service:
This is the server where the singleton service will initially be started.
The new singleton service appears in the list of defined singleton services. The Class Name and Prefered Server are listed.
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 a singleton service.
