Querying the application state using wsadmin scripting

Use the wsadmin tool and scripting to determine if an application is running.

Before you begin

There are two ways to complete this task. The example in this topic uses the AdminConfig object to create and configure a shared library. Alternatively, you can use the createSharedLibrary script in the AdminResources script library to configure shared libraries.

The scripting library provides a set of procedures to automate the most common administration functions. You can run each script procedure individually, or combine several procedures to quickly develop new scripts.

Procedure

  1. Start the wsadmin scripting tool.
  2. Determine the application state.
    The following example queries the presence of the Application MBean to find out whether the application is running.
    • Using Jacl:
      $AdminControl completeObjectName type=Application,name=myApplication,*
    • Using Jython:
      print AdminControl.completeObjectName('type=Application,name=myApplication,*')
    Table 1. completeObjectName command elements. Run the completeObjectName command to see if an application is running.
    $ is a Jacl operator for substituting a variable name with its value
    AdminControl is an object that enables the manipulation of MBeans running in a WebSphere® Application Server process
    completeObjectName is an AdminControl command
    type=Application,name=myApplication is the hierarchical containment path of the configuration object
    print is a Jython command

Results

If myApplication is running, then an MBean is created. Otherwise, the command returns nothing. If myApplication is running, the output resembles the following:
WebSphere:cell=mycell,name=myApplication,mbeanIdentifier=cells/mycell/applications/myApplication.ear/
deployments/myApplication/deployment.xml#ApplicationDeployment_1,type=Application,node=mynode,Server=
dmgr,process=dmgr,J2EEName=myApplication
