Clustered enviroments -Starting/Stopping Managed servers, NodeManager & Admin server from single node

Question

Hi,
We have 5 node Weblogic cluster. At the time of some mass activities like patching we have to stop all our managed, Admin Servers and node manager and it takes a lot of time to do this by logging in to all 5 managed servers and stopping all components. Though we have node manager configured so we can stop managed servers from console itself, but still have to login to each server to stop NodeManager and Oracle Http Servers.
Things become worse when wee have to shutdown almost 15-20 instances.
Is there a way (using wlst or shell script) that we can do all these tasks from by logging in to just one server?
Thanks,
Suraj

The simple code below would shutdown all the running Servers. Some of the APIs for ex MBeanHome are deprecated..still work though..if your concerned about that..I am working on the same using JMX API..if you want I could share that too. And also as described in the below link..you can Cluster stop and start using WLST commands.  Managing the Server Life Cycle - 12c Release 1 (12.1.1)
