How do I determine if an application is running using wsadmin Jython script?

Question

I can get a list of instlled applications but how do I get the status using Jython?

Answer 1

I dont think there is any direct method to get the application running status, You can get the object from the AdminControl using the following code

serverstatus = AdminControl.completeObjectName('type=Application,name='your_application_name',*')
print serverstatus

If serverstatus returns null, then the application is not running, if the application is running then the details of the applications would be printed.

Answer 2

Here is what I use based on Snehan's answer.

import string

def getAppStatus(appName):
    # If objectName is blank, then the application is not running.
    objectName = AdminControl.completeObjectName('type=Application,name=' + appName + ',*')
    if objectName == "":
        appStatus = 'Stopped'
    else:
        appStatus = 'Running'
    return appStatus

def appStatusInfo():
    appsString = AdminApp.list()
    appList = string.split(appsString, '\r\n')

    print '============================'
    print ' Status |    Application   '
    print '============================'

    # Print apps and their status
    for x in appList:
        print getAppStatus(x) + ' | ' + x

    print '============================'



appStatusInfo()

Sample output

============================
 Status |    Application
============================
Running | DefaultApplication
Running | IBMUTC
Stopped | some-ear
Running | another-ear
============================

Answer 3

The following IBM documentation should help:

• WAS InfoCenter: Querying the application state using wsadmin scripting

• IBM Technote: Listing enterprise application status using wsadmin script

To summarize, if the application is running on an application server, an Application MBean will be registered. In order to determine if the application is running, you can query for the presence of these MBeans.

Answer 4

There is some more modification required in Matthieu, Cormier's script.

Here we go.

It will work in any line separator. Generally AdminApp.list() will use "\" as the line seperator

import string

def getAppStatus(appName):
    # If objectName is blank, then the application is not running.
    objectName = AdminControl.completeObjectName('type=Application,name='+ appName+',*')
    if objectName == "":
        appStatus = 'Stopped'
    else:
        appStatus = 'Running'
    return appStatus

def appStatusInfo():
    Apps=AdminApp.list().split(java.lang.System.getProperty("line.separator"))

    print '============================'
    print ' Status |    Application   '
    print '============================'

    # Print apps and their status
    for x in Apps:
        print "X value", x
        print getAppStatus(x) + ' | ' + x

    print '============================'



appStatusInfo()
