Set background applications using scripting

 

Overview

Perform the following steps to enable or disable a background application. Background applications specify whether the application must initialize fully before the server starts. The default setting is false and this indicates that server startup will not complete until the application starts. If you set the value to true, the application starts on a background thread and server startup continues without waiting for the application to start. The application may not ready for use when the application server starts.

 

Procedure

  1. Start wsadmin

  2. Locate the application deployment object for the application. For example:

    • Jacl 

      set applicationDeployment [$AdminConfig getid /Deployment:adminconsole/ApplicationDeployment:/]

    • Jython 

      applicationDeployment = AdminConfig.getid('/Deployment:adminconsole/ApplicationDeployment:/')

    where:

    set is a Jacl command
    applicationDeployment is a variable name
    $ is a Jacl operator for substituting a variable name with its value
    AdminConfig is an object that represents the WebSphere Application Server configuration
    getid is an AdminConfig command
    Deployment is a type
    ApplicationDeployment is a type
    adminconsole is the name of the application

  3. Enable the background application. For example:

    • Jacl 

      $AdminConfig modify $applicationDeployment "{backgroundApplication true}"
$AdminConfig save

    • Jython 

      AdminConfig.modify(applicationDeployment, ['backgroundApplication', 'true'])

    where:

    $ is a Jacl operator for substituting a variable name with its value
    AdminConfig is an object that represents the WAS configuration
    modify is an AdminConfig command
    applicationDeployment is a variable name that was set in step 1
    backgroundApplication is an attribute
    true is the value of the backgroundApplication attribute

  4. In a network deployment environment only, synchronize the node.
