In order to mount an external registry, you have to define the remote instance. This could use either the JDBC-based configuration, the Atom-based configuration model or the WebService-based configuration model.
JDBC-Based Remote Instance Configuration
Following is an example configuration of a remote instance:

The Atom-based remote instance configuration is not recommended for use in a production deployment as it does not support transactions. |

It is recommended to refrain from mounting a target path under "/_system/governance" of a remote registry to path "/_system/config". Similarly, refrain from mounting a target path under "/_system/config" of a remote registry to path "/_system/governance". Such configurations can produce unpredictable results. For example, with the following mounting configurations, "/_system/governance" will be mounted to the correct path, which is "/_system/governance/mounting/governance" but "/_system/config" will be mounted to " /_system/governance/mounting/governance/ mounting/config". | Code Block |

| <mount path="/_system/config" overwrite="true">
<instanceId>instanceId</instanceId>
<targetPath>/_system/config</targetPath>
</mount>
<mount path="/_system/governance" overwrite="true">
<instanceId>instanceId</instanceId>
<targetPath>/_system/governance</targetPath>
</mount> |
