Duplexing servers is building a system by configuring duplicate hardware equipment to provide CUBRID HA. This method will prevent any interruptions in a server in case of occurring a hardware failure.
A broker defines server connection order and connects to a server according to the defined order. If the connected server fails, the broker connects to the server with the next highest priority. This requires no processing in the application side. The actions taken when the broker connects to another server may differ according to the current mode of the broker. For details on the server connection order and configuring broker mode, see cubrid_broker.conf.
