How to Set the Deletion Policy for a State Migration Point
Updated: November 1, 2013
Applies To: System Center 2012 Configuration Manager, System Center 2012 Configuration Manager SP1, System Center 2012 R2 Configuration Manager
In System Center 2012 R2 Configuration Manager, 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.
Note |
|---|
The Configuration Manager console displays the deletion delay time in days, whereas SMPStoreDeletionDelayTimeInMinutes and SMPStoreDeletionCycleTimeInMinutes are stored in minutes. |
To set the deletion policy
Set up a connection to the SMS Provider. For more information, see About the SMS Provider in Configuration Manager.
Make a connection to the state migration point resources section of the site control file.
Get the embedded properties.
Update SMPStoreDeletionDelayTimeInMinutes and SMPStoreDeletionCycleTimeInMinutes.
Commit the changes to the site control file.
Example
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.
Sub SetDeletionPolicy(connection, _
context, _
siteCode, _
deletionPolicyDays)
' Load site control file and get SMS state migration point section.
connection.ExecMethod "SMS_SiteControlFile.Filetype=1,Sitecode=""" & siteCode & """", "Refresh", , , context
Query = "SELECT * FROM SMS_SCI_SysResUse " & _
"WHERE RoleName = 'SMS State Migration Point' " & _
"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
' Display state migration point server name.
wscript.echo "SMS State Migration Point Server: " & SCIComponent.NetworkOSPath
' Loop through the array of embedded property instances.
For Each vProperty In SCIComponent.Props
' Setting: SMPStoreDeletionDelayTimeInMinutes
If vProperty.PropertyName = "SMPStoreDeletionDelayTimeInMinutes" Then
wscript.echo " "
wscript.echo vProperty.PropertyName
wscript.echo "Current value " & vProperty.Value
' Modify the value.
vProperty.Value = deletionDelayMinutes
wscript.echo "New value " & deletionDelayMinutes
End If
' Setting: SMPStoreDeletionCycleTimeInMinutes
If vProperty.PropertyName = "SMPStoreDeletionCycleTimeInMinutes" Then
wscript.echo " "
wscript.echo vProperty.PropertyName
wscript.echo "Current value " & vProperty.Value
' Modify the value.
vProperty.Value = deletionCycleMinutes
wscript.echo "New value " & deletionCycleMinutes
End If
Next
' Update the component in your copy of the site control file. Get the path
' to the updated object, which could be used later to retrieve the instance.
Set SCICompPath = SCIComponent.Put_( , context)
Next
' 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
End Sub
