Remarques

CreateSyncAgentByDefault la valeur par défaut est false .

Affectez la valeur true à CreateSyncAgentByDefault lorsque vous devez planifier la synchronisation ou lorsque vous devez synchroniser l’abonnement à partir de SQL Server Management Studio . Spécifiez la valeur false si l’agent de réplication est toujours Démarré par programme sans utiliser l' SQL Server agent.

Lorsque vous spécifiez la valeur false pour CreateSyncAgentByDefault , les MergeSynchronizationAgent TransSynchronizationAgent objets ou obtenus à partir SynchronizationAgent des SynchronizationAgent Propriétés ou ne disposent pas de suffisamment d’informations pour synchroniser correctement l’abonnement. Pour plus d’informations, consultez procédure : synchroniser un abonnement par extraction (programmation RMO).

La spécification de la false valeur CreateSyncAgentByDefault pour et Create l’appel à revient à exécuter SP_ADDPULLSUBSCRIPTION (Transact-sql) sans exécuter sp_addpullsubscription_agent (transact-SQL) ou exécuter sp_addmergepullsubscription (Transact -SQL) sans exécuter sp_addmergepullsubscription_agent (Transact-SQL).
