I am using WebSphere Application Server 7.0 running on windows. I need a wsadmin script which will do a Stop, Sync and Start of all the JVM on the node and then send an email after all the JVM's are started. I want the email notification include that it stopped, synced and started the JVM's.

Please help me out.

Thanks

Please look at these samples:
http://www.ibm.com/developerworks/websphere/library/samples/SampleScripts.html

http://wsadminlib.blogspot.com.br/2010/12/how-to-start-node-agent-using-scripting.html

Basic script from last link:
# Import python os library to execute external commands
import os


# Import wsadminlib.py (update this to your own wsadminlib.py path)
execfile('/tmp/wsadminlib.py')


# Node name
nodename = 'node1'


# Server name
servername = 'nodeagent'


# Counter used to keep track of while loop execution
counter = 0


while(counter < 2):
    # Check if Node agent is running
    print "\nIs Node agent running?"
    isItRunning = isServerRunning(nodename,servername)
    
    # If Node agent is running let's stop it
    # else let's start it
    if (isItRunning):
        print "YES\n"
        
        print "Request issued to stop Node agent\n"
        stopServer( nodename, servername, immediate=False )
        counter = counter + 1
    else:
        print "NO\n"
        print "Request issued to start Node agent\n"
        os.system('/opt/WAS61/profiles/node1/bin/startNode.sh')
        counter = counter + 1

Thanks Walter. But the one which you attached above is just stopping and starting the node agent. I need one to stop all the JVM's on one node and then perform Sync and and then start all JVM's. Repeat this step for the other node as well. Once this is done, an email needs to be send confirming all task's has been done.

I don't know how to start writing a script. Any help will be much appreciated.

Thanks

Ok, let me see if I can came with something. But I believe that you need to get started on reading anything you can from the first link.

To start creating a script, is pretty much what you saw above. Python is really a simple and very efficient and effective language.

http://www.python.org is the place to start with python.

Cheers,
Walter.

--Walter, thanks again.

 I took few samples from this forum and wrote this one. Its works but needs modification.

I need this script to perform stop/sync/start and send email on node1 and then do the same stop/syn/start on node2 and send the email.

I took the wsadmin control commands from WebSphere Admin Console by stopping the JVM, syncing the nodes manually. But this needs to be refined. As i said above, if you can help me out using this as base script, I really appreciate it. The email thing is working fine. So please when you modify this, please include all the output results come out in email.

Thanks
