In Microsoft System Center Configuration Manager 2007, you configure the state migration point deletion policy by updating the SMPStoreDeletionDelayTimeInMinutes and SMPStoreDeletionCycleTimeInMinutes embedded properties. The deletion policy defines when the state migration point should remove data marked for deletion.

The Configuration Manager console displays the deletion delay time in days, whereas SMPStoreDeletionDelayTimeInMinutes and SMPStoreDeletionCycleTimeInMinutes are stored in minutes.

To set the deletion policy

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

  2. Make a connection to the state migration point resources section of the site control file.

  3. Get the embedded properties.

  4. Update SMPStoreDeletionDelayTimeInMinutes and SMPStoreDeletionCycleTimeInMinutes.

  5. Commit the changes to the site control file.


The following example method sets the deletion policy for a state migration point. The example receives the number of days, converts the value to minutes, and updates the deletion policy accordingly.

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

Visual Basic Script  Copy Code
Sub SetDeletionPolicy(connection, 	_

			"AND SiteCode = '" & siteCode & "'"

	Set SCIComponentSet = connection.ExecQuery(Query, , , context)

	' Convert days to minutes (1440 = 24 *60).
	deletionDelayMinutes = deletionPolicyDays * 1440
	deletionCycleMinutes = 1440

	' Only one instance is returned from the query.
	For Each SCIComponent In SCIComponentSet

			 Set SCICompPath = SCIComponent.Put_( , context)
	' Commit the change to the actual site control file.
	Set InParams = connection.Get("SMS_SiteControlFile").Methods_("CommitSCF").InParameters.SpawnInstance_
	InParams.SiteCode = siteCode
	connection.ExecMethod "SMS_SiteControlFile", "CommitSCF", InParams, , context

The example method has the following parameters:





  • Managed: WqlConnectionManager

  • VBScript: SWbemServices

A valid connection to the SMS Provider.

context (VBScript)

  • VBScript: SWbemContext

  • Managed: String

  • VBScript: String

The Configuration Manager server that the state migration point is running on.


  • Managed: String

  • VBScript: String

The Configuration Manager site code.


  • Managed: Integer

  • VBScript: Integer

Number of days before data deletion.
