The Registry Manager maintains a set of registries for caching WebSphere Commerce run-time data.
If the data in the tables associated with a registry is changed, you will need to refresh that registry for the change to take effect. For example, if a new entry is added to the URLREG table, the UrlRegistry has to be refreshed. Otherwise, the WebSphere Commerce run-time environment will not recognize the new URL.
The Registry Manager can manage any registries registered to it, including customer created registries.
You can register a registry with the Registry Manager by defining a new registry under the registries node in the instance.xml file.
