Gérer manuellement ou automatiquement la base de données Windows Server Update Services (WSUS)

  • Article

La maintenance courante de la base de données WSUS (SUSDB) est importante pour garantir l’intégrité et les performances optimales de l’application. Cet article décrit les étapes et les scripts concis pour gérer MANUELLEment ou automatiquement SUSDB.

Pour plus d’informations, consultez le guide complet de la maintenance de WSUS et de Configuration Manager SUP.

Combien de temps prend la maintenance ?

La durée de maintenance peut varier en fonction des ressources de l’ordinateur, notamment de l’UC, de la mémoire et de la capacité de disque. Les facteurs affectant la durée de maintenance incluent l’heure depuis la dernière maintenance, le nombre de produits et de classifications sélectionnés et le volume de mises à jour qui doivent être nettoyées.

Dans un petit environnement, avec des produits et classifications minimes et une maintenance récente sur SUSDB, les scripts automatiques avec l’option RA peuvent prendre moins d’une minute pour s’exécuter. Toutefois, dans certains cas, il peut prendre plusieurs jours. Si cela prend plus de temps que prévu et que vous ne pouvez pas effectuer la maintenance correctement, vous devez créer une nouvelle base de données SUSDB.

Requête pour obtenir le nombre de mises à jour

Un nombre excessif de mises à jour remplacées, refusées et obsolètes provoquent souvent une mauvaise santé de SUSDB. Pour obtenir le nombre de mises à jour, exécutez la requête SQL suivante. Si le nombre dans les trois dernières colonnes du résultat de la requête dépasse quelques centaines, la maintenance doit être effectuée.

use SUSDB;

DECLARE @numberOfMatch INT
DECLARE @tmpTable TABLE (
    name VARCHAR(25)
)
INSERT INTO @tmpTable
EXEC spGetObsoleteUpdatesToCleanup
SELECT @numberOfMatch = @@ROWCOUNT
select
(Select count (*) from vwMinimalUpdate ) 'Total Updates',
(Select count (*) from vwMinimalUpdate where declined=0) as 'Live Updates',
(Select count (*) from vwMinimalUpdate where IsSuperseded =1) as 'Superseded',
(Select count (*) from vwMinimalUpdate where IsSuperseded =1 and declined=0) as 'Superseded but not declined',
(Select count (*) from vwMinimalUpdate where declined=1) as 'Declined',
(Select count (*) from vwMinimalUpdate where IsSuperseded =1 and declined=1) 'Superseded & Declined',
(select Count(*)  From @tmpTable ) 'Obsolete Updates Needed to be cleaned'

Gérer manuellement la base de données WSUS (SUSDB)

Important

  • Exécutez les étapes sur chaque serveur WSUS de la hiérarchie. Lorsque vous effectuez un nettoyage et supprimez des éléments des serveurs WSUS, commencez au niveau le plus bas de la hiérarchie.
  • Vérifiez que toutes les synchronisations planifiées sont désactivées, soit dans Configuration Manager (le cas échéant) soit sur des serveurs WSUS autonomes.

Les étapes suivantes peuvent résoudre de nombreux problèmes liés à l’analyse et à la synchronisation. S’il existe un grand nombre de mises à jour refusées, vous devrez peut-être répéter les étapes 9 à 12 plusieurs fois. Après chaque exécution, exécutez la requête SQL pour vérifier que le nombre de mises à jour diminue. Les étapes 8 et 9 peuvent entraîner des erreurs à chaque fois, ce qui est attendu. Par conséquent, vous devez répéter les étapes 9 à 12 plusieurs fois. Certaines étapes (en particulier l’étape 9) peuvent prendre plusieurs heures.

  1. Exécutez le script SQL décrit dans Les performances lentes de la procédure spDeleteUpdate.

  2. Réduisez les fichiers SUSDB.

  3. Réduisez la base de données SUSDB.

  4. Réindexez et mettez à jour les statistiques sur SUSDB.

    1. Pour réindexer SUSDB, exécutez le script SQL suivant :

      EXEC sp_MSforeachtable @command1="SET QUOTED_IDENTIFIER ON;ALTER INDEX ALL ON ? REBUILD;"

    2. Pour mettre à jour les statistiques, exécutez le script SQL suivant :

      Exec sp_msforeachtable "UPDATE STATISTICS ? WITH FULLSCAN, COLUMNS"

  5. Effectuez un nettoyage de l’historique de synchronisation.

    Note

    S’il existe un grand nombre de synchronisations, la console WSUS peut se bloquer.

    USE SUSDB 
GO 
DELETE FROM tbEventInstance WHERE EventNamespaceID = '2' AND EVENTID IN ('381', '382', '384', '386', '387', '389')

  6. Effectuez un nettoyage des mises à jour remplacées antérieures à 30 jours ou en fonction de votre configuration spécifique.

    Note

    • La valeur de 30 la première ligne indique le nombre de jours entre aujourd’hui et la date de publication, pendant laquelle les mises à jour remplacées ne doivent pas être marquées comme refusées.
    • Dans Configuration Manager, cette valeur doit s’aligner sur les règles de remplacement configurées dans les propriétés du composant du point de mise à jour logicielle (SUP).
    • Sur les serveurs WSUS autonomes, spécifiez le nombre de jours pendant lesquels vous souhaitez conserver les mises à jour remplacées. Par exemple, définissez la valeur 60 au lieu de 30 conserver deux mois de mises à jour remplacées. Toutes les mises à jour antérieures à cette période seront marquées comme refusées et ensuite nettoyées.
    DECLARE @thresholdDays INT = 30   -- Specify the number of days between today and the release date during which superseded updates should not be marked as declined. If Configuration Manager is being used with WSUS, this value should match the configuration of supersedence rules in the software update point (SUP) component properties.
DECLARE @testRun BIT = 0          -- Set this value to 1 to test without declining anything. 
-- There shouldn't be any need to modify anything after this line.
DECLARE @uid UNIQUEIDENTIFIER
DECLARE @title NVARCHAR(500)
DECLARE @date DATETIME
DECLARE @userName NVARCHAR(100) = SYSTEM_USER 
DECLARE @count INT = 0 
DECLARE DU CURSOR FOR
       SELECT MU.UpdateID, U.DefaultTitle, U.CreationDate FROM vwMinimalUpdate MU 
       JOIN PUBLIC_VIEWS.vUpdate U ON MU.UpdateID = U.UpdateId
       WHERE MU.IsSuperseded = 1 AND MU.Declined = 0 AND MU.IsLatestRevision = 1
       AND MU.CreationDate < DATEADD(dd,-@thresholdDays,GETDATE())
       ORDER BY MU.CreationDate 
PRINT 'Declining superseded updates older than ' + CONVERT(NVARCHAR(5), @thresholdDays) + ' days.' + CHAR(10) 
OPEN DU
FETCH NEXT FROM DU INTO @uid, @title, @date
WHILE (@@FETCH_STATUS > - 1)
BEGIN  
       SET @count = @count + 1
       PRINT 'Declining update ' + CONVERT(NVARCHAR(50), @uid) + ' (Creation Date ' + CONVERT(NVARCHAR(50), @date) + ') - ' + @title + ' ...'
       IF @testRun = 0
              EXEC spDeclineUpdate @updateID = @uid, @adminName = @userName, @failIfReplica = 1 
       FETCH NEXT FROM DU INTO @uid, @title, @date
END 
CLOSE DU
DEALLOCATE DU 
PRINT CHAR(10) + 'Attempted to decline ' + CONVERT(NVARCHAR(10), @count) + ' updates.'

  7. Effectuez un nettoyage des mises à jour obsolètes.

    DECLARE @var1 INT
DECLARE @msg nvarchar(100)
CREATE TABLE #results (Col1 INT)
        INSERT INTO #results(Col1) EXEC spGetObsoleteUpdatesToCleanup
DECLARE WC Cursor
        FOR
        SELECT Col1 FROM #results
OPEN WC
        FETCH NEXT FROM WC
        INTO @var1
        WHILE (@@FETCH_STATUS > -1)
        BEGIN SET @msg = 'Deleting' + CONVERT(varchar(10), @var1)
        RAISERROR(@msg,0,1) WITH NOWAIT EXEC spDeleteUpdate @localUpdateID=@var1
        FETCH NEXT FROM WC INTO @var1 END        
CLOSE WC
        DEALLOCATE WC

        DROP TABLE #results

  8. À partir d’une invite Windows PowerShell avec élévation de privilèges, exécutez le script suivant pour lancer l’Assistant Nettoyage WSUS :

    [reflection.assembly]::LoadWithPartialName("Microsoft.UpdateServices.Administration") | out-null
$wsus = [Microsoft.UpdateServices.Administration.AdminProxy]::GetUpdateServer();
$cleanupScope = new-object Microsoft.UpdateServices.Administration.CleanupScope;
$cleanupScope.DeclineSupersededUpdates = $true
$cleanupScope.DeclineExpiredUpdates = $true
$cleanupScope.CleanupObsoleteUpdates = $true
$cleanupScope.CompressUpdates = $true
$cleanupScope.CleanupObsoleteComputers = $true
$cleanupScope.CleanupUnneededContentFiles = $true
$cleanupManager = $wsus.GetCleanupManager();
$cleanupManager.PerformCleanup($cleanupScope);

  9. À partir d’une invite Windows PowerShell avec élévation de privilèges, exécutez le script suivant pour effectuer un nettoyage des mises à jour refusées :

    [reflection.assembly]::LoadWithPartialName("Microsoft.UpdateServices.Administration")
$wsus = [Microsoft.UpdateServices.Administration.AdminProxy]::GetUpdateServer();
$wsus.GetUpdates() | Where {$_.IsDeclined -eq $true} | ForEach-Object {$wsus.DeleteUpdate($_.Id.UpdateId.ToString()); Write-Host $_.Title removed }

  10. Réduisez les fichiers SUSDB.

  11. Réduisez la base de données SUSDB.

  12. Réindexez et mettez à jour les statistiques sur SUSDB.

    1. Pour réindexer SUSDB, exécutez le script SQL suivant :

      EXEC sp_MSforeachtable @command1="SET QUOTED_IDENTIFIER ON;ALTER INDEX ALL ON ? REBUILD;"

    2. Pour mettre à jour les statistiques, exécutez le script SQL suivant :

      Exec sp_msforeachtable "UPDATE STATISTICS ? WITH FULLSCAN, COLUMNS"

Gérer automatiquement la base de données WSUS (SUSDB)

Le script PowerShell suivant réplique les étapes manuelles. Lorsque le script est exécuté, un fichier SUSDB-Maintenance.log est créé et ouvert.

Important

Vérifiez que toutes les synchronisations planifiées sont désactivées, soit dans Configuration Manager (le cas échéant) soit sur des serveurs WSUS autonomes.
