Configuring Cluster Elements 

Use

This procedure enables you to modify the default name of a cluster element that was assigned to it during the cluster element creation. If necessary, you can also 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).

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

Procedure

       1.      Start the J2EE Engine Visual Administrator.

       2.      Choose Server/Dispatcher → Kernel → Cluster Manager → Properties tab.

       3.      Modify the required property values depending on the tasks you want to perform:

                            a.      Use element.name to specify the name of the cluster element.

There are no restrictions about the name.

                            b.      Use element.joinPort to specify the port on which the server process listens for connections.

The port value must not be: greater than 65535, less than 1024, or a “well known” port.

This property is available only on server processes.

       4.      Choose  Save Properties to save your changes and restart the cluster node.
