I see. Then how are users able to maintenance their server without disturbing the service? For example, I need to maintenance my server without disturbing my services. So I need to shut down the server but I don't want any message loss. In normal situation (without clustering), I would stop the producer and let the consumer get all messages before shutting down the server. With clustering, I don't know which clients connect to one specific server that I want to shut down due to HA-JNDI. Is there possible that clients check which server node that they connect to?
