Stopping the WebSphere Application Server
Note: By default, WebSphere Application
                Server 7.0 creates and configures a default server named 
        server1
                during installation. If you named your server something other than the default
                value, then substitute that name for server1 in the following
                steps.To stop the WebSphere Application Server:
Start a command prompt.
Navigate to the
<websphere_install_dir>\AppServer\profiles\profile_name\binWebSphere/AppServer/profiles/profile_name/bindirectory. For example:cd Z:\IBM\WebSphere\AppServer\profiles\AppSrv01\bincd /u01/IBM/WebSphere/AppServer/profiles/AppSrv01/binIssue the command
stopServerfollowed by the Application Server name. For example:stopServer server1./stopServer.sh server1
This command is case sensitive.
Note: If administrative
                security has been enabled for the WebSphere Application Server profile then use the
                following command to stop the
                    servers:
        Z:\IBM\WebSphere\AppServer\profiles\AppSrv01\bin >
                    stopServer server1 user <admin_user_name> -password
                    <admin_user_password>Tip: The
                Application Server can also be stopped through the Windows Services Applet. Each
                profile that you configured will have a corresponding service that is automatically
                created when you created the profile.
        Note: Starting with Tools Release 8.97,
                you can use the Server Manager to stop the WebSphere process.
