A cluster is started using the start-cluster command. The following example starts the cluster named mycluster. The command prompts for the administrative password.
$ asadmin start-cluster --host myhost --port 1234 --user admin mycluster
myhost is the administrative server host, 1234 is the administrative port, admin is the administrative username.
For the full syntax, type asadmin help start-cluster. When a cluster is started, all the server instances in the cluster get started. A cluster without instances cannot be started.
