Before you begin
A path service is persistent map that can be used to store the mapping of a group of messages to a messaging resource, such as a member of a distributed destination or a store-and-forward agent. It provides a way to enforce message ordering by pinning messages to a member of a cluster hosting servlets, distributed queue members, or store-and-forward agents.
In a clustered server environment, a path service can targeted to a migratable target. A migratable target is a special target that can serve as a grouping of migratable JMS services, such as a path service, and which is active on only server member in a WebLogic cluster. In a cluster, a recommended best practice is to target a path service to a migratable target, so that a member server will not be a single point of failure. This way the path service can be manually migrated from an unhealthy server onto a healthy server, either in the event of server crash or for scheduled maintenance.
Note: Once you create a path service, you cannot rename it. Instead, you must delete it and create another one that uses the new name.
Note: When a path service is targeted to a migratable target (see Step 4), it cannot use the default store, so a custom store must be configured and targeted to the same migratable target. And, as a best practice, the path service and its store should be the only users of that migratable target.
