Setting background applications using wsadmin scripting

You can enable or disable a background application using scripting and the wsadmin tool.

About this task

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. 啟動 wsadmin Scripting 工具。
  2. Locate the application deployment object for the application. For example:
    • Using Jacl:
      set applicationDeployment [$AdminConfig getid /Deployment:adminconsole/ApplicationDeployment:/]
    • Using Jython:
      applicationDeployment = AdminConfig.getid('/Deployment:adminconsole/ApplicationDeployment:/')
    Table 1. getid command elements. Run the getid command to get an application object.
    Element Description
    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 product 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:
    • Using Jacl:
      $AdminConfig modify $applicationDeployment "{backgroundApplication true}"
    • Using Jython:
      AdminConfig.modify(applicationDeployment, ['backgroundApplication', 'true'])
    Table 2. modify command elements. Run the modify command to set the backgroundApplication value.
    Element Description
    $ is a Jacl operator for substituting a variable name with its value
    AdminConfig is an object that represents the product 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. Save the configuration changes.
    請利用下列指令範例來儲存您的配置變更:
    AdminConfig.save()
  5. Synchronize the node.
    請利用 AdminNodeManagement Script 程式庫中的 syncActiveNode 或 syncNode Script,將配置變更傳播給節點。
    • 利用 syncActiveNodes Script,依照下列範例所示,將變更傳播給 Cell 中的每個節點:
      AdminNodeManagement.syncActiveNodes()
    • 利用 syncNode Script,依照下列範例所示,將變更傳播給特定的節點:
      AdminNodeManagement.syncNode("myNode")
