wsadmin + jython restart WAS appserver

Question

Is it possible to stop/start WAS appserver using wsadmin (jacl/jython). I want to detele all caches on profile and then restart WAS appserver. I'm using wsadmin as standalone.

Answer 1

From wsadmin you may issue a command (using Jython):

AdminControl.invoke(AdminControl.queryNames('WebSphere:*,type=Server,node=%s,process=%s' % ('YourNodeName', 'YourServerName')), 'restart')

works with WAS Base & ND. With ND you have another option:

AdminControl.invoke(AdminControl.queryNames('WebSphere:*,type=Server,node=%s,process=%s' % ('YourNodeName', 'YourServerName')), 'stop')
# now your server is stopped, you can do any cleanup
# and then start the server with NodeAgent
AdminControl.invoke(AdminControl.queryNames('WebSphere:*,type=NodeAgent,node=%s' % 'YourNodeName'), 'launchProcess', ['YourServerName'], ['java.lang.String'])

Answer 2

Check out the wsadminlib script. It has over 500 methods written for you to perform specific wsadmin tasks. Also check out related wsadminlib blog - you'll definitely want to view the powerpoint on this site to get an overview of usage.

You don't specify which caches you would like to clear. If you want to clear dynacache, wsadminlib offers clearDynaCache, clearAllProxyCaches, and others as well as server restart methods.

Example usage:

import sys
execfile('/opt/software/portalsoftware/wsadminlib/wsadminlib.py')
clearAllProxyCaches()
for (nodename,servername) in listAllAppServers():    
    clearDynaCache( nodename, servername, dynacachename )
    save()
    maxwaitseconds=300
    restartServer( nodename, servername, maxwaitseconds)
