Stopping a domain shuts down its administration server and application server instance. When stopping a domain, the server instance stops accepting new connections and then waits for all outstanding connections to complete. This process takes a few seconds because the server instance must complete its shutdown process. While the domain is stopped, the Admin Console or most asadmin commands cannot be used.
$ asadmin stop-domain domain1
If there is only one domain, then the domain name is optional. For the full syntax, type asadmin help stop-domain.
From the Start menu select Programs -> Sun Microsystems -> Application Server-> Stop Admin Server.
