Disabling application loading in deployed targets using wsadmin scripting

You can use the AdminConfig object and scripting to disable application loading in deployed targets.

About this task

The following example uses the AdminConfig object to disable application loading in deployed targets:

Procedure

  1. Inicie a ferramenta de script wsadmin.
  2. Obtain the Deployment object for the application and assign it to the deployments variable, for example:
    • Using Jacl:
      set deployments [$AdminConfig getid /Deployment:myApp/]
    • Using Jython:
      deployments = AdminConfig.getid("/Deployment:myApp/")
    Table 1. getid Deployment command elements. Run the getid command to get a deployment object.
    Element Description
    set is a Jacl command
    deployments 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 an attribute
    myApp is the value of the application name
    Evitar Problemas Evitar Problemas: If you are using the Jython scripting language, make sure that you read the notes concerning a space character within application names.gotcha
    Example output:
    myApp(cells/mycell/applications/myApp.ear/deployments/myApp|deployment.xml#Deployment_1)
  3. Obtain the target mappings in the application and assign them to the targetMappings variable, for example:
    • Using Jacl:
      set deploymentObj1 [$AdminConfig showAttribute $deployments deployedObject]
      
      set targetMap1 [lindex [$AdminConfig showAttribute $deploymentObj1 targetMappings] 0]
      Example output:
      (cells/mycell/applications/ivtApp.ear/deployments/ivtApp|deployment.xml#DeploymentTargetMapping_1)
    • Using Jython:
      deploymentObj1 = AdminConfig.showAttribute(deployments, 'deployedObject')
      
      targetMap1 = AdminConfig.showAttribute(deploymentObj1, 'targetMappings')
      
      targetMap1 = targetMap1[1:len(targetMap1)-1].split(" ")
      
      print targetMap1
      Evitar Problemas Evitar Problemas: When you attempt to obtain the target mappings in the application through scripting and then assigning those values to the targetMappings variable, be aware when the application has a space in the name or blank. In these cases, you must compensate for the occurrence of a blank or space character as the Jython example demonstrates. Errors can occur if you do not make this adjustment. Consider the following scenarios:
      • If only one single DeploymentTargetMapping value exists within the deployment.xml file, you can either split the targetMappings value with a space or a line.separator entry. The line.separator entry syntax works when the application name contains a space, such as "IVT Application". For example:
        targetMap1 = targetMap1[1:len(targetMap1)-1].split(" ")   
        or
        targetMap1 = 
          targetMap1[1:len(targetMap1)-1].split(java.lang.System.getProperty("line.separator"))
      • If multiple DeploymentTargetMapping values exist within the deployment.xml file, split the targetMappings values with a space. However, you must also use "\" and " ", as appropriate, when the application name or deployment target string contains a space character. For example:
        targetMap1 = targetMap1[1:len(targetMap1)-1].split(" ") 
      gotcha
      Example output:
      ['(cells/mycell/applications/ivtApp.ear/deployments/ivtApp|deployment.xml#DeploymentTargetMapping_1)']
    Table 2. showAttribute command elements. Run the showAttribute command to assign target mappings.
    Element Description
    set is a Jacl command
    deploymentObj1 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
    showAttribute is an AdminConfig command
    deployments evaluates the ID of the Deployment object that is specified in step number 1
    deployedObject is an attribute
    targetMap1 is a variable name
    targetMappings is an attribute
    lindex is a Jacl command
    print is a Jython command
  4. Disable the loading of the application on each deployed target, for example:
    • Using Jacl:
      foreach tm $targetMap1 {$AdminConfig modify $tm {{enable false}}}
    • Using Jython:
      for targetMapping in targetMap1: AdminConfig.modify(targetMapping, [["enable", "false"]])
  5. Save the configuration changes.
    Utilize o seguinte exemplo de comando para salvar suas alterações de configuração:
    AdminConfig.save()
  6. In a network deployment environment only, synchronize the node.
    Utilize os scripts syncActiveNode ou syncNode na biblioteca de scripts AdminNodeManagement para propagar as alterações de configuração para o(s) nó(s).
    • Utilize o script syncActiveNodes para propagar as alterações para cada nó na célula, conforme demonstra o seguinte exemplo:
      AdminNodeManagement.syncActiveNodes()
    • Utilize o script syncNode para propagar as alterações para um nó específico, conforme demonstra o seguinte exemplo:
      AdminNodeManagement.syncNode("myNode")
