#Purpose:  This script starts and stops all of the the process schedulers, app servers, and web servers defined in an environment
#Usage:  ps.sh <command> [cc]
# where <command> is one of the following:
#      start - Starts all web/app/process scheduler/PSEMAgents
#      stop - Stops all web/app/process scheduler/PSEMAgents
#      kill - Kills all web/app/process scheduler/PSEMAgents, and cleans up IPCS
#      restart - Executes the Stop then the Start commands
# If cc is specified on the command line, cache will be cleared for the web, app server, process scheduler, and PSEMAgent, 
#    and the app server and process scheduler will be reconfigured.
