Stopping and Starting a Cluster using wsadmin and jython for 5.1

A simple jython script that accepts two incoming arguments to stop a cluster within a cell. This script is built with global use in mind, meaning you can create multiple shell scripts to pass the arguments to stopCluster.py. This can easily be manipulated to start the cluster too!

Let the script begin

# Global stopCluster
#-----------------------------------------------------------------
#
# The purpose of this example is to demonstrate the invocation
# of stopping a cluster passing args through a shell script.
#
# This script can be included in the wsadmin command invocation like this:
#
# ./wsadmin -lang jython -f stopCluster.py clusterName cell
#
# Simply create a shell script with the following
# #!/bin/sh
# # Change the directory to your WAS_HOME/bin
# cd /opt/websphere/bin
# # issue the wsadmin command with the two arguments
# # make sure your path to stopCluster.py is correct
# # in the example below it is located in WAS_HOME/bin
# # clusterName below = your cluster name found via the admin console
# # cell below = your cell name found via the admin console
# ./wsadmin.sh -lang jython stopCluster.py clusterName cell
#
# The script expects one parameter:
# arg1 - cluster Name
# arg2 - cell Name
#
