javax.management.InstanceNotFoundException: WebSphere: name=ApplicationManager

  • 1.  javax.management.InstanceNotFoundException: WebSphere: name=ApplicationManager

    I've successfully created and executed a Jython script to install a particular war-file.  But, then, when I try to do similarly to start it, I get the error below.

    I've checked the appName.  I did, at first, have an issue, such that, whereas in most places in the script the actual war-file name is used, in one place the dots in the name seem to have to be converted into underscores.  And, at first, I saw that I'd installed the war-file with appName containing dots instead of underscores.  But, even after I re-installed with the name having underscores instead of dots, the start-script still failed with the error below.

    Does the following error mean that the ApplicationManager isn't found?  Or that the specified war-file isn't found?  Because, when I run the AdminApp.list() command, it includes in the list of installed apps the one I'm trying to programmatically start (with the underscores in the name).

    I also tried what some of the log-info from the command suggested: namely, using the option for running with the older version of Jython ("-usejython21 true"), but that didn't change anything.

    Here's the command:

    AdminControl.invoke( 'WebSphere: name=ApplicationManager, process=WAS90QA, platform=proxy, node=QA_WAS90QA, version=9.0.5.10, type=ApplicationManager, mbeanIdentifier=ApplicationManager, cell=QA_WAS90QA, spec=1.0', 'startApplication', '[{name_with_underscores_ommitted}]'

    Any feedback would be much appreciated.

    Hello Larry,
    does it work if you run the command from the `wsadmin.sh` shell? Actually you are passing the application name as a list containing a set (`'[{name_with_underscores_ommitted}]'`). Sure that's right? I've checked one of my scrips and there I'm invoking the command like the following: `AdminControl.invoke(appManagerMBean, "startApplication", appName)` 

    From the error message you have pasted: `javax.management.InstanceNotFoundException: WebSphere: name=ApplicationManager, process=WAS90QA, platform=proxy, node=QA_WAS90QA, version=9.0.5.10, type=ApplicationManager, mbeanIdentifier=ApplicationManager, cell=QA_WAS90QA, spec=1.0` is seems however that your problem is that the AppManager MBean is incorrect. Please can you check and verify that this is correct and exists?

    Thanks - Hermann

    For people who have landed on this page googling for 'InstanceNotFoundException' :)

    As Hermann mentioned, the problem is that MBean can not be found (identified).

    You might consider using command completeObjectName to create a string representation of a MBean that is based on a fragment. Please note that if the system finds several MBeans that match the fragment, the command returns the first one.

    So the solution could be:

    objNameString = AdminControl.completeObjectName("WebSphere:name=ApplicationManager,*")
    AdminControl.invoke(objNameString, 'startApplication', '[{name_with_underscores_ommitted}]')

    In our case it helped with invoking a function by AdminControl.
