Your application can create a System Center 2012 R2 Configuration Manager maintenance window by using the SMS_CollectionSettings Server WMI Class and SMS_ServiceWindow Server WMI Class classes and properties.

To create a maintenance window

  1. Set up a connection to the SMS Provider. For more information, see About the SMS Provider in Configuration Manager.

  2. Get the existing collection settings instance by using the supplied collection ID.

  3. Create and populate the properties of a new service window object by using the SMS_ServiceWindow Server WMI Class class.

  4. Add the new SMS_ServiceWindow object to the collection settings instance obtained earlier.

  5. Save the collection settings instance and properties.

Note
The example below includes additional steps, primarily to handle the overhead of dealing with the maintenance window objects, which are stored as embedded objects in the collection settings instance.

Example

The following example method creates a maintenance window for a collection, assuming that the collection instance can modified. This might not be the case at child sites, where the collections are owned by the parent site(s).

For information about calling the sample code, see Calling Configuration Manager Code Snippets.

Visual Basic Script  Copy Code
Sub CreateMaintenanceWindow(connection, 							 _
							targetCollectionID, 					 _
							newMaintenanceWindowName, 			 _
							newMaintenanceWindowDescription, 		_
							newMaintenanceWindowServiceWindowSchedules, _
							newMaintenanceWindowIsEnabled, 		_
							newMaintenanceWindowServiceWindowType)
									 
	' Build a query to get the specified collection. 
	 collectionSettingsQuery = "SMS_CollectionSettings.CollectionID='" & targetCollectionID & "'"
	 
	' Get the collection settings instance for the targetCollectionID.
	Set allCollectionSettings = connection.ExecQuery("Select * From SMS_CollectionSettings Where CollectionID = '" & targetCollectionID & "'")
   
	' If a collection settings instance does not exist for the target collection, create one.
	If allCollectionSettings.Count = 0 Then
		Wscript.Echo "Creating collection settings instance."
		Set collectionSettingsInstance = connection.Get("SMS_CollectionSettings").SpawnInstance_
		collectionSettingsInstance.CollectionID = targetCollectionID
		collectionSettingsInstance.Put_
	End If  

	' Get the specific collection settings instance.
	Set collectionSettingsInstance = connection.Get("SMS_CollectionSettings.CollectionID='" & targetCollectionID &"'" )
			 
	' Create and populate a temporary SMS_ServiceWindow object with the new maintenance window values. 
	Set tempServiceWindowObject = connection.Get("SMS_ServiceWindow").SpawnInstance_
			 
	' Populate temporary SMS_ServiceWindow object with the new maintenance window values.
	tempServiceWindowObject.Name = newMaintenanceWindowName
	tempServiceWindowObject.Description = newMaintenanceWindowDescription
	tempServiceWindowObject.ServiceWindowSchedules = newMaintenanceWindowServiceWindowSchedules
	tempServiceWindowObject.IsEnabled = newMaintenanceWindowIsEnabled
	tempServiceWindowObject.ServiceWindowType = newMaintenanceWindowServiceWindowType

	' Populate the local array list with the existing service window objects (from the target collection).
	tempServiceWindowArray = collectionSettingsInstance.ServiceWindows
  
	' Add the newly created service window object to the temporary array.
	ReDim Preserve tempServiceWindowArray (Ubound(tempServiceWindowArray) + 1)
	Set tempServiceWindowArray(Ubound(tempServiceWindowArray)) = tempServiceWindowObject

	' Replace the existing service window objects from the target collection with the temporary array that includes the new service window.
	collectionSettingsInstance.ServiceWindows = tempServiceWindowArray

	' Save the collection settings instance with the new service window object.
	collectionSettingsInstance.Put_

	' Output success message.
	wscript.echo "New Maintenance Window created."
