How to uninstall an application that is already stopped


The problem is that if the application is "stopped" this will return nothing. But i still want to uninstall it anyway. I don't know the application name, i'm getting all applications installed on a Server and then uninstalling them all.

apps = AdminControl.queryNames('type=Application,node=' + nodeName + ',process=' + serverName + ',*').split()

Here is my code.

serverObj = AdminControl.completeObjectName('type=Server,node=%s,name=%s,*' % (nodeName, serverName))
serverID = AdminConfig.getid('/Node:%s/Server:%s/' % (nodeName, serverName))

if serverID == "": 
    print "Can't find the server, exiting..."
    sys.exit(1)
else:
    cellName = AdminControl.getAttribute(serverObj, 'cellName')

#Uninstall Apps
apps = AdminControl.queryNames('type=Application,node=' + nodeName + ',process=' + serverName + ',*').split()
appManager=AdminControl.queryNames('type=ApplicationManager,node=' + nodeName + ',process=,*')
if len(apps) > 0:
    for app in apps:
        appName = AdminControl.getAttribute(app, 'name')
        AdminControl.invoke(appManager,'stopApplication', appName)
        print "Uninstalling application: " + appName
        AdminApp.uninstall(appName)
else:
    print "No applications to uninstall"

Solution

  • You can use the below snippet to uninstall all Apps deployed on the target server:

    #Get the list of all Apps deployed in target server
    installedApps=AdminApp.list("WebSphere:cell=%s,node=%s,server=%s" % (cellName, nodeName, serverName))
    
    #Check if there are any installed Apps on the server
    if len (installedApps) > 0:
        #if there are installed Apps, iterate through the list and uninstall Apps one by one
        for app in installedApps.splitlines():
            print "uninstalling "+ app +" ...."
            AdminApp.uninstall(app)
        #Save the changes
        AdminConfig.save()
    else:
        #if there are no installed Apps, do nothing
        print "No applications to uninstall"
