Solucionar problemas SQL Server Service Broker no Operations Manager
O Microsoft System Center Operations Manager depende de SQL Server Service Broker para implementar todas as operações de tarefa. Se SQL Server Service Broker estiver desabilitado, todas as operações de tarefa serão afetadas. O comportamento resultante pode variar de acordo com a tarefa iniciada. Por exemplo, você pode ter os seguintes problemas:
- O Assistente de Descoberta parece estar sendo executado sem parar, mesmo que a tarefa em segundo plano tenha sido concluída.
- A redefinição da integridade de um monitor nunca é concluída, mesmo que a tarefa em segundo plano tenha sido concluída.
Este artigo fornece etapas comuns de solução de problemas para SQL Server problemas do Service Broker.
Observação
As consultas SQL neste artigo usam um nome padrão do para o banco de OperationsManager dados operacional. Substitua OperationsManager pelo nome do banco de dados operacional se você usar um nome de banco de dados diferente.
Verifique se SQL Server Service Broker está habilitado
Execute a seguinte consulta SQL:
SELECT is_broker_enabled FROM sys.databases WHERE name = 'OperationsManager'Se o valor retornado do
is_broker_enabledcampo for 1 (um), SQL Server Service Broker estiver habilitado. Caso contrário, execute as seguintes consultas SQL para habilitá-la:ALTER DATABASE OperationsManager SET SINGLE_USER WITH ROLLBACK IMMEDIATE ALTER DATABASE OperationsManager SET ENABLE_BROKER ALTER DATABASE OperationsManager SET MULTI_USER
Reiniciar o Serviço de Acesso a Dados do System Center
Depois que SQL Server Service Broker estiver habilitado, reinicie o OMSDK (System Center Data Access Service).
Em SQL Server Management Studio, vá para oAgente de Serviços OperationsManager> de Bancos> de Dados.
Expanda Filas e Serviços.
Verifique se há uma fila e um serviço cujo nome contém os seguintes valores:
- O endereço IP do servidor de gerenciamento que criou a fila e o serviço.
- A ID do processo do serviço OMSDK (Microsoft.Mom.Sdk.ServiceHost.exe) que está em execução nesse servidor de gerenciamento.
Neste exemplo, o endereço IP do servidor de gerenciamento é 192.168.10.10. O PID do serviço OMSDK é 3092.
Se você tiver mais de um servidor de gerenciamento, cada servidor de gerenciamento terá uma fila e um serviço separados do Service Broker.
Se você não conseguir encontrar a fila e o serviço correspondentes, reinicie o serviço OMSDK novamente.
Se você ainda não conseguir encontrar a fila e o serviço, o Service Broker atual poderá estar corrompido. Vá para a próxima etapa para recriar o SQL Server Service Broker.
Recriar o SQL Server Service Broker
Execute as seguintes consultas SQL em ordem:
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 goReinicie o serviço OMSDK nos servidores de gerenciamento para recriar o Service Broker e a fila e o serviço. Esse processo pode exigir duas reinicializações:
- A primeira reinicialização recria o Service Broker
- A segunda reinicialização recria a fila de serviço
Verifique se o SQL Server Service Broker ainda está habilitado. Se estiver desabilitado, habilite-o.
Verifique se a fila e o serviço do Service Broker são gerados, conforme descrito na etapa 4 no Serviço de Acesso a Dados do System Center.
Solução de problemas avançada
Se as etapas anteriores não resolve o problema, colete um rastreamento SQL Server Profiler que inclua eventos do Service Broker.
Rastreamento de exemplo quando o serviço OMSDK cria o serviço e a fila quando ele é reiniciado:
Rastreamento de exemplo ao redefinir a integridade de um monitor:
Rastreamento de exemplo quando o Service Broker está desabilitado:
Além disso, execute o script SQL a seguir no banco de dados operacional para coletar logs de diagnóstico.
