You use the management console to communicate with the management daemon, which controls a cluster from the center. You can access the management console from any PC via the binary ndb_mgm, and then ndb_mgm can either pick up its connect string from my.cnf or you can specify it directly (see appendixA, "MySQL Cluster Binaries"). The management daemon, ndb_mgmd, must be running on the management server in order for any commands issued to the client to take effect (otherwise, you get an error).
