Websphere : Jython stop & start server scripts

Stop Script:

Let’s check if there are any java (server) process running ?

(Please note you will need python installed on your box to run this script)

[was61@scripts]$ python startcell.py /opt/IBM/WebSphere/AppServer

startServer dmgr -profileName dmgr

I have tested it and it is only bringing up DMGR,Will need some tweaking
