This section describes the format of the persistence configuration file.
Persistence configuration file location
The persistence configuration file can be found in
However this file only exists if the Rhino node has been started at least once.
If the node has yet to be started, or if the
persistence.xml file is deleted, then the persistence configuration is obtained from
Every node in a Rhino cluster has the same persistence configuration.
A Rhino node that boots and joins an existing cluster will obtain its persistence configuration from the other nodes in the cluster.
The cluster configuration will be saved into the node’s
