For persistent messaging, you must configure a custom persistent store that is targeted to the same migratable target as the JMS service.

When using automatic service migration, the Node Manager is required to get health monitoring information about the member servers involved, as follows:

* Consensus leasing – Node Manager must be running on every machine hosting managed servers within the cluster.
