A path service is a 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.
The default persistent file store requires no additional configuration. However, if you require a custom file store or JDBC store to suit your specific needs, you need to create the custom store before creating a path service.
Note: 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. A path service can also be automatically migrated from an unhealthy server instance to a healthy server instance, with the help of the server health monitoring services.
