Hi JIEXA,
you can achieve this using WLST :
1.Start WLST (%WL_HOME%\common\bin\wlst.cmd)
2.Connect to the managed server (not the admin server)
3.shutdown the server
Code sample
connect('username','password','t3://localhost:7011')
shutdown('server1','Server','false',1000,block='false')
Hope this help
Emmanuel
