Script to Clean expired updates from update lists, packages and deployments

  • Artikel

<---My college Kurt has pointed out to me that the code snip to trigger the update synchronization has some problem. So I remove that. As a workaround, you can trigger a full update synchronization from the UI-->

 

If you use Software Update Point (SUP) in a System Center Configuration Manager 2007 hierarchy, you may face the problem of expired updates.

Consider the following scenario:

Updates are saved in the SMS database as CIs (Configuration Items). All CIs will flow downward to the child sites in the hierarchy.

If the updates are expired, the CI will also be marked as expired. Each site (central or child primary) has the Delete Aged Configuration Manager Data job that removes CIs that have been expired for 90 days (by default) which are not locally referenced. -- “Locally referenced” means it’s not used in any Update Lists created by this site.

So if you create Update Lists on the child site which contains a CI (Update) that has been expired, the CI is not removed from the child site since it is referenced by an local Update List; But the CI is removed from the parent site by the “Delete Aged Configuration Manager Data” job because Update Lists don’t flow up to the parent site.

Now if there is a new third tier primary site (a grandchild site), its SUP WILL NOT get this CI from the central site’s SUP because it has already been removed from the top-most SUP. Its SUP WILL get the Update List which contains the expired CI from its parent site. So the new grandchild site will fail to process this Update List that reference the now-missing CI.

To solve this problem, we have written a script that can clear expired updates from the Update Lists, Update Deployment and Update Packages. As a best practice, we’d suggest to clear up the expired updates and in a one day schedule:

  • Set the update cleanup age to 1 day. Site Settings->Site Maintenance->Tasks-> Delete Aged Configuration Manager Data Properties->Set Delete data older than (days): to 1
  • Run the attached script on the site where you create Update Lists every day. You can use Windows Task Schedule to do it.

Here comes the sample script:

Dim Debugging 'If debug logging is enabled

Dim connection 'the Service Object

Dim context 'SMS WMI context

Dim SMSSiteCode 'The site code of the site that we peform clear up

Dim SMSServer 'The machine name of the site server

Dim SMSProvider 'The machine name of the provider

Dim UserName 'username used to connect to the remote server

Dim Password 'Password used to connect to the remote server

 

 

DebugLogging = false

Set objArgs = WScript.Arguments

call ParseParameters(objArgs)

Log("SMSServer: "&SMSServer)

Log("UserName: "&UserName)

Log("Password: "&Password)

 

Set context = CreateObject("WbemScripting.SWbemNamedValueSet")

' Add the standard SMS context qualifiers to the context object.

context.Add "LocaleID", "MS\1033"

context.Add "MachineName", SMSServer

context.Add "ApplicationName", "ClearExpiredUpdates"

 

Set connection = Connect(SMSServer,UserName,Password)

 

If Err.Number<>0 Then

    Wscript.Echo "Call to connect failed"

End If

 

 

'collect all expired CIs

'save to Variable - ExpiredCIs

Query = "SELECT * FROM SMS_SoftwareUpdate " & _

        "WHERE IsExpired='TRUE'"

Set ExpiredCIs = connection.ExecQuery(Query, ,wbemFlagForwardOnly Or wbemFlagReturnImmediately, Context)

Log("Expired CI IDs: ")

For each ExpiredCI in ExpiredCIs

    Log(ExpiredCI.CI_ID)

'Remove from UpdateList

call RemoveExpiredUpdatesFromUpdateList(connection,context,SMSSiteCode,ExpiredCIs)

    If you do not tell people how to use this script and how to set/use arguments (username password, smsserver) then is usless for most of your Readers... Hope ypu will add some comment rows to clarify how tos :-) It will be surely appreciated Thanks

    Awesome post. There is no need to explain arguments and variables, as this is not a classroom, rather a solution for the issue, which an experienced person needs to know before playing with scripts! It is like some gifts you a plane and then you crib saying I dont know how to ride a bicycle !!! :-)
