Changing the Port of a Cluster Node
If you need to change the port number of a cluster node, you can do this. However, because the port number is part of the name of the server instance in the cluster, changing the port number causes it to not be recognized as a cluster member by the rest of the cluster members. Follow the procedure to change the port number of a cluster node that you want to be a part of the same cluster.
Changing the HTTP base port value also changes the value of all derived ports after the next TDV restart (with the exception of the Repository and Cache database ports, which will remain the same).
To change the port number of a cluster node
1. In Manager, remove the TDV Server node from the cluster.
2. Change the TDV Server port number in Studio:
a. Open Studio on one of the cluster nodes.
b. From the main menu, choose Administration > Configuration.
c. Locate Port (Current) to display the current port setting for this TDV Server.
d. Change the port number.
e. Click OK.
3. Shut down the TDV Server.
4. Restart the TDV Server so that the port change takes effect.
5. In Manager, rejoin the cluster.
Note: In the Port configuration panel, the Derived TDV Ports shows that HTTP base port 7 is reserved for Active Cluster/JGroups. Active Cluster uses the JGroups Java library to track the nodes that are up and down. Heartbeat messages are sent on a different port (the derived port) than the port used for metadata.
