Create and delete configuration objects using properties files and wsadmin scripting

Use this topic to use an extracted properties file to create or delete configuration objects that are not server, cluster, application, or authorization group object types.

Use the PropertiesBasedConfiguration command group for the AdminTask object, we can use properties files to create and delete configuration objects from the environment.

You cannot apply a z/OS operating system properties file directly to a distributed operating system. Similarly, we cannot apply a distributed operating system properties file directly to a z/OS operating system..

Tasks

1. Start the wsadmin scripting tool.

2. Extract a properties file for the subtype of interest from your configuration.

   Use the extractConfigProperties command to extract the properties file for the resource of interest. The following example extracts the properties for the ThreadPool resource:

   AdminTask.extractConfigProperties('[-propertiesFileName threadPool.props -configData 
    Server=server1 -filterMechanism SELECTED_SUBTYPES -selectedSubTypes [ThreadPool]]')
   

   The command generates a template file similar to the following sample template:

   # # SubSection 1.0.1.4 # Thread pools # ResourceType=ThreadPool 
    ImplementingResourceType=Server ResourceId=Cell=!{cellName}:Node=!{nodeName}:Server=!{serverName}:Thr 
    eadPoolManager=ID#ThreadPoolManager_1:ThreadPool=ID#builtin_ThreadPool_4 #  # #Properties #
   	maximumSize=20 #integer name=Default inactivityTimeout=5000 #integer minimumSize=5
   #integer isGrowable=false #boolean 
   

3. Create or delete configuration objects.

   To create a new thread pool or delete the existing thread pool, modify the ResourceId attribute.

   • To create a new thread pool, set the ResourceId attribute to a value that does not exist in the configuration. In the following example, note that the ThreadPool=ID#builtin_ThreadPool_4 ResourceId is replaced with the ThreadPool=ID#ThreadPool_99999 ResourceId, which does not exist in the configuration:

      # # SubSection 1.0.1.4 # Thread pools # ResourceType=ThreadPool 
      ImplementingResourceType=Server ResourceId=Cell=!{cellName}:Node=!{nodeName}:Server=!{serverName}:Thr 
      eadPoolManager=ID#ThreadPoolManager_1:ThreadPool=ID#ThreadPool_99999 #  # #Properties # maximumSize=20 
      #integer name=myThreadPool inactivityTimeout=5000 #integer minimumSize=5 #integer isGrowable=false #Boolean 
     

     Run the applyConfigProperties command to apply the properties file to the configuration.:

     AdminTask.applyConfigProperties('[-propertiesFileName threadPool.props]')
     

     The command automatically validates the properties file, then uses the modified values in the file to create a new thread pool in the configuration.

   • To delete the thread pool, specify the DELETE=true property in the header of the properties file:

     # # SubSection 1.0.1.4 # Thread pools # ResourceType=ThreadPool 
      ImplementingResourceType=Server ResourceId=Cell=!{cellName}:Node=!{nodeName}:Server=!{serverName}:Thr 
      eadPoolManager=ID#ThreadPoolManager_1:ThreadPool=myThreadPool DELETE=true #  # #Properties # maximumSize=20 
     #integer  name=myThreadPool inactivityTimeout=5000 #integer minimumSize=5 #integer isGrowable=false #boolean 
     

     Run the deleteConfigProperties command to use the properties file to remove the thread pool from the configuration, as the following command demonstrates:

     AdminTask.deleteConfigProperties('[-propertiesFileName threadPool.props]')
     

     The command automatically validates the properties file, then uses the new attribute and value in the file to remove the thread pool from the configuration.

     If we run the deleteConfigProperties command before you add the DELETE=true attribute and value to the properties file, the command resets each property to the default value. The system completely removes properties that do not have default values.

4. Save the configuration changes.

   AdminConfig.save()
