Renaming a cluster doesn't not require a reboot and doesn't drop connections.   For troubleshooting the client balance, see SmartConnect Client Connections are not Balanced Between Nodes and, if further needed, Troubleshoot your SmartConnect Configuration hth -- Peter
Hi, I need to rename the cluster. Is this task non-disruptive? Also, I noticed on the client connection its heavily used on node 1. How do I balance this across the other nodes. Thanks, [IMAGE][IMAGE]
