Configuring Cluster Communication PortsLocate this document in the navigation structure

Context

This procedure enables you to change the assigned join port of a server process, on which the server process listens for connections (for example, when the port assigned to the cluster element is already in use by another program).

Caution

Do not modify the cluster element ID ( element.clusterId ), group ID ( element.groupId ), name ( element.name ) or type ( element.type ) properties. Modifying any of these properties leads to problems within the cluster communication and operation.
