How to uninstall an application that is already stopped

Question

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"

When you said "this will return nothing." What is "this". The code snippet where you get the list of apps? The mbean invocation to uninstall it? — F Rowe, Mar 07 '19 at 22:48
i mean, if I run AdminControl.queryNames('type=Application,node=' + nodeName + ',process=' + serverName + ',*').split(), apps will = "" — leSourCil, Mar 11 '19 at 15:21

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"

You can use AdminApp.list() to obtain the list of apps for a target scope. So for server scope:

AdminApp.list("WebSphere:cell=yourCellName,node=yourNodeName,servers=yourServerName”)

With that information, you can then use AdminApp.uninstall() to uninstall the app, for example:

AdminApp.uninstall('NameOfApp')
