Creating cluster connections
A server connection to a cluster (formerly known as a network relay) is a setting on an IBM® UrbanCode® Deploy server that opens a Java™ Message Service (JMS) port for communication with other servers. These cluster connections are necessary for servers in a cluster to communicate.
Cluster connections create a JMS mesh, which facilitates JMS communication between servers in a clustered high-availability server configuration. See Setting up high-availability clusters.
Cluster connections are required only if you have more than one server. Also, they facilitate communication only among servers; cluster connections are not used for agents or agent relays. Because the servers use the same database, you can create connections on any server; the other servers all have access to those connections.
On any server in the cluster, click
.The Connect Server To Server Cluster dialog box is displayed.
- Enter a name for the cluster connection.
- In the Host field, enter the host name or IP address of the target server.
In the Port field, enter the JMS communication port of the
The default server JMS communication port number is 7918.
- Select the Active check box.
- Click Save.
- On the same server, repeat the process to create a connection to each server in the cluster, including a connection that points to the current server itself.
Restart the targeted servers.
If you create the cluster connections on server A, for example, restart servers B and C to ensure that they can communicate with one another.
