Hi, yes, that's true, I don't know why they don't create them. You can stop the server using the admin console. right click on the server name and select start/stop this server, you'll be asked for a confimation and also for a force shutdown or gracefull shutdown. You may also use the comand line admin to create a stopweblogic script if you want, as follow(for windows):
notice that you'll have to set the correct machine, port, username and password for the instance you want to shut down. regards.
