Maintain the Windows Server Update Services (WSUS) database manually or automatically

  • Artículo

Routine maintenance of the WSUS database (SUSDB) is important to ensure the application's health and optimal performance. This article describes concise steps and scripts to maintain SUSDB manually or automatically.

For more information, see The complete guide to WSUS and Configuration Manager SUP maintenance.

How long does the maintenance take?

The maintenance duration might vary depending on the machine's resources, including CPU, memory, and disk capacity. Factors affecting the maintenance duration include the time since the last maintenance, the number of selected products and classifications, and the volume of updates that need to be cleaned up.

In a small environment, with minimal products and classifications and recent maintenance on SUSDB, the automatic scripts with the RA option might take less than one minute to run. However, in some cases, it might take several days to complete. If it takes longer than expected and you can't complete the maintenance successfully, you need to create a new SUSDB.

Query to obtain the update count

An excessive number of superseded, declined, and obsolete updates often cause poor health of SUSDB. To obtain the update count, run the following SQL query. If the counts in the last three columns of the query result exceed a few hundred, maintenance should be performed.

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(Select count (*) from vwMinimalUpdate where IsSuperseded =1) as 'Superseded',
(Select count (*) from vwMinimalUpdate where IsSuperseded =1 and declined=0) as 'Superseded but not declined',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(Select count (*) from vwMinimalUpdate where IsSuperseded =1 and declined=1) 'Superseded & Declined',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'

Maintain the WSUS database (SUSDB) manually

Important

  • Run the steps on each WSUS server in the hierarchy. When performing a cleanup and removing items from WSUS servers, start at the lowest level of the hierarchy.
  • Ensure that any scheduled synchronizations are disabled, either in Configuration Manager (if used) or on standalone WSUS servers.

The following steps can resolve many issues with scanning and synchronization. If there are a large number of declined updates, you might need to repeat steps 9 through 12 multiple times. After each run, execute the SQL query to confirm that the update count is decreasing. Steps 8 and 9 might result in errors each time, which is expected. Therefore, you need to repeat steps 9 through 12 multiple times. Some steps (especially step 9) might take several hours to complete.

  1. Run the SQL script described in Slow performance of the spDeleteUpdate procedure.

  2. Shrink the SUSDB files.

  3. Shrink the SUSDB database.

  4. Reindex and update statistics on SUSDB.

    1. To reindex SUSDB, run the following SQL script:

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

    2. To update statistics, run the following SQL script:

      Exec sp_msforeachtable "UPDATE STATISTICS ? WITH FULLSCAN, COLUMNS"

  5. Perform a cleanup of the synchronization history.

    Note

    If there are a large number of synchronizations, the WSUS console may crash.

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

  6. Perform a cleanup of superseded updates older than 30 days or according to your specific configuration.

    Note

    • The value of 30 in the first line indicates the number of days between today and the release date, during which superseded updates shouldn't be marked as declined.
    • In Configuration Manager, this value should align with the supersedence rules configured in the software update point (SUP) component properties.
    • On standalone WSUS servers, specify the number of days you want to retain superseded updates. For instance, set the value to 60 instead of 30 to keep two months of superseded updates. Any updates older than this period will be marked as declined and subsequently cleaned up.
    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. Perform a cleanup of obsolete updates.

    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. From an elevated Windows PowerShell prompt, run the following script to initiate the WSUS Cleanup wizard:

    [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. From an elevated Windows PowerShell prompt, run the following script to perform a cleanup of declined updates:

    [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. Shrink the SUSDB files.

  11. Shrink the SUSDB database.

  12. Reindex and update statistics on SUSDB.

    1. To reindex SUSDB, run the following SQL script:

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

    2. To update statistics, run the following SQL script:

      Exec sp_msforeachtable "UPDATE STATISTICS ? WITH FULLSCAN, COLUMNS"

Maintain the WSUS database (SUSDB) automatically

The following PowerShell script replicates the manual steps. When the script is executed, a SUSDB-Maintenance.log file will be created and opened.

Important

Ensure that any scheduled synchronizations are disabled, either in Configuration Manager (if used) or on standalone WSUS servers.

<# SUSDB-Maintenance

Requirements
* WID must be local.
* Remote connections to SQL are now supported; choose [S] Change SQL Server from the menu to set the SQL Server.
