Un souci avec la WMI de Exchange 2010 ? voici comment reinitialiser les compteurs de performance d'Exchange 2010

Avec powershell :

add-pssnapin Microsoft.Exchange.Management.PowerShell.Setup

CD 'C:\Program Files\Microsoft\Exchange Server\V14\Setup\Perf'

$files=get-childitem . *.xml | where-object {!($_.psiscontainer)}

foreach ($file in $files) { Remove-PerfCounters -DefinitionFileName $file }

foreach ($file in $files) { New-PerfCounters -DefinitionFileName $file }

éventuellement redémarrer les services Exchange concernés pour récupérer des valeurs (en particulier "Microsoft Exchange transport")

Si il vous manque encore des classes WMI (par Exemple : Win32_PerfFormattedData_MSExchangeIS_MSExchangeIS), vérifier la clé de registre suivante (1 = disabled.. mettez 0) :

HKLM\SYSTEM\CurrentControlSet\services\MSExchangeIS\Performance\

Disable Performance Counters (DWORD) = 0

Ce script permet de rebuilder tous les indexes de toutes les bases d'un serveur :

DECLARE @Database VARCHAR(255) 
DECLARE @Table VARCHAR(255)
DECLARE @cmd NVARCHAR(500)
DECLARE @fillfactor INT

SET @fillfactor = 80

DECLARE DatabaseCursor CURSOR FOR
SELECT name FROM master.dbo.sysdatabases 
WHERE name NOT IN ('master','model','msdb','tempdb','distrbution') 
ORDER BY 1

OPEN DatabaseCursor

FETCH NEXT FROM DatabaseCursor INTO @Database
WHILE @@FETCH_STATUS = 0
BEGIN

   SET @cmd = 'DECLARE TableCursor CURSOR FOR SELECT table_catalog + ''.'' + table_schema + ''.'' + table_name as tableName FROM ' + @Database + '.INFORMATION_SCHEMA.TABLES WHERE table_type = ''BASE TABLE''' 

   -- create table cursor
   EXEC (@cmd)
   OPEN TableCursor 

   FETCH NEXT FROM TableCursor INTO @Table 
   WHILE @@FETCH_STATUS = 0 
   BEGIN 

       -- SQL 2000 command
       --DBCC DBREINDEX(@Table,' ',@fillfactor) 
       
       -- SQL 2005 command
       SET @cmd = 'ALTER INDEX ALL ON ' + @Table + ' REBUILD WITH (FILLFACTOR = ' + CONVERT(VARCHAR(3),@fillfactor) + ')'
       EXEC (@cmd)

       FETCH NEXT FROM TableCursor INTO @Table 
   END 

   CLOSE TableCursor 
   DEALLOCATE TableCursor

   FETCH NEXT FROM DatabaseCursor INTO @Database
END
CLOSE DatabaseCursor 
DEALLOCATE DatabaseCursor
