Risolvere i problemi di SQL Server Service Broker in Operations Manager
Microsoft System Center Operations Manager dipende da SQL Server Service Broker per implementare tutte le operazioni delle attività. Se SQL Server Service Broker è disabilitato, tutte le operazioni delle attività sono interessate. Il comportamento risultante può variare in base all'attività avviata. Ad esempio, è possibile che si verifichino i problemi seguenti:
- L'individuazione guidata sembra essere in esecuzione all'infinito, anche se l'attività in background è stata completata.
- La reimpostazione dell'integrità di un monitor non termina mai, anche se l'attività in background è stata completata.
Questo articolo illustra i passaggi comuni per la risoluzione dei problemi di SQL Server Service Broker.
Nota
Le query SQL in questo articolo usano un nome predefinito per OperationsManager
il database operativo. Sostituire OperationsManager
con il nome del database operativo se si usa un nome di database diverso.
Verificare se SQL Server Service Broker è abilitato
Eseguire la query SQL seguente:
SELECT is_broker_enabled FROM sys.databases WHERE name = 'OperationsManager'
Se il valore restituito del
is_broker_enabled
campo è 1 (uno), SQL Server Service Broker è abilitato. In caso contrario, eseguire le query SQL seguenti per abilitarla:ALTER DATABASE OperationsManager SET SINGLE_USER WITH ROLLBACK IMMEDIATE ALTER DATABASE OperationsManager SET ENABLE_BROKER ALTER DATABASE OperationsManager SET MULTI_USER
Riavviare il servizio di accesso ai dati di System Center
Dopo aver abilitato SQL Server Service Broker, riavviare System Center Data Access Service (OMSDK).
In SQL Server Management Studio passare a Database>OperationsManager>Service Broker.
Espandere Code e servizi.
Verificare che siano presenti una coda e un servizio il cui nome contiene i valori seguenti:
- Indirizzo IP del server di gestione che ha creato la coda e il servizio.
- ID processo del servizio OMSDK (Microsoft.Mom.Sdk.ServiceHost.exe) in esecuzione nel server di gestione.
In questo esempio, l'indirizzo IP del server di gestione è 192.168.10.10. Il PID del servizio OMSDK è 3092.
Se sono presenti più server di gestione, ogni server di gestione avrà una coda e un servizio di Service Broker separati.
Se non è possibile trovare la coda e il servizio corrispondenti, riavviare il servizio OMSDK.
Se non è ancora possibile trovare la coda e il servizio, Service Broker corrente potrebbe essere danneggiato. Passare al passaggio successivo per ricreare il SQL Server Service Broker.
Ricreare l'SQL Server Service Broker
Eseguire le query SQL seguenti nell'ordine seguente:
declare @i int set @i=0 DECLARE @handle UNIQUEIDENTIFIER declare @service_id int declare @service_name nvarchar (100) declare @far_service nvarchar (70) DECLARE conv_cur CURSOR FAST_FORWARD FOR SELECT CONVERSATION_HANDLE, service_id, far_service FROM SYS.CONVERSATION_ENDPOINTS OPEN conv_cur; FETCH NEXT FROM conv_cur INTO @handle, @service_id, @far_service; while (@@FETCH_STATUS = 0 and (@i<500000)) BEGIN select top 1 @service_name=name from sys.services where service_id=@service_id begin END CONVERSATION @handle WITH CLEANUP end FETCH NEXT FROM conv_cur INTO @handle, @service_id, @far_service; set @i=@i+1 END CLOSE conv_cur DEALLOCATE conv_cur go declare @servicename sysname declare @queuename sysname declare @cmd nvarchar(200) declare @serverqid nvarchar(25) set @serverqid='%Queue_mid%' while ((select count(*) from sys.service_queues WHERE name like @serverqid )>1) begin set @servicename= (select top 1 s.name from sys.service_queues as q join sys.services as s on q.object_id=s.service_queue_id WHERE q.name like @serverqid order by q.create_date asc) set @cmd= 'DROP SERVICE '+@servicename exec sp_sqlexec @cmd set @queuename= (select top 1 Object_name(object_id) from sys.service_queues WHERE name like @serverqid order by create_date asc) set @cmd= 'DROP QUEUE '+@queuename exec sp_sqlexec @cmd end go ALTER DATABASE OperationsManager SET SINGLE_USER WITH ROLLBACK IMMEDIATE ALTER DATABASE OperationsManager SET NEW_BROKER WITH ROLLBACK IMMEDIATE ALTER DATABASE OperationsManager SET MULTI_USER go ALTER DATABASE OperationsManager SET SINGLE_USER WITH ROLLBACK IMMEDIATE ALTER DATABASE OperationsManager SET ENABLE_BROKER ALTER DATABASE OperationsManager SET MULTI_USER go
Riavviare il servizio OMSDK nei server di gestione per ricreare Service Broker e la coda e il servizio. Questo processo potrebbe richiedere due riavvii:
- Il primo riavvio ricrea Service Broker
- Il secondo riavvio ricrea la coda del servizio
Verificare che il SQL Server Service Broker sia ancora abilitato. Se è disabilitato, abilitarlo.
Verificare che la coda e il servizio Service Broker vengano generati, come descritto nel passaggio 4 in Riavviare il servizio di accesso ai dati di System Center.
Risoluzione avanzata dei problemi
Se i passaggi precedenti non risolvono il problema, raccogliere una traccia SQL Server Profiler che include gli eventi di Service Broker.
Traccia di esempio quando il servizio OMSDK crea il servizio e la coda al riavvio:
Traccia di esempio durante la reimpostazione dell'integrità di un monitoraggio:
Traccia di esempio quando Service Broker è disabilitato:
Eseguire inoltre lo script SQL seguente nel database operativo per raccogliere i log di diagnostica.
