Propriété PullSubscription.CreateSyncAgentByDefault

Obtient ou définit si le travail de l'agent utilisé pour démarrer l'Agent de réplication pour la synchronisation de l'abonnement est créé en même temps que l'abonnement.

Espace de noms :  Microsoft.SqlServer.Replication
Assembly :  Microsoft.SqlServer.Rmo (en Microsoft.SqlServer.Rmo.dll)

public bool CreateSyncAgentByDefault { get; set; }

Valeur de propriété

Type : Boolean
true si la synchronisation est créée ; sinon, false.

CreateSyncAgentByDefault à la valeur par défaut false.

Spécifiez une valeur true pour CreateSyncAgentByDefault lorsque vous devez planifier une synchronisation, ou lorsque vous devez synchroniser l'abonnement à partir de SQL Server Management Studio. Spécifiez une valeur false si l'agent de réplication est toujours démarré par programme sans utiliser l'Agent SQL Server.

Lorsque vous spécifiez une valeur false pour CreateSyncAgentByDefault, l'objet MergeSynchronizationAgent ou TransSynchronizationAgent obtenu à partir de la propriété SynchronizationAgent ou SynchronizationAgent n'aura pas assez d'informations pour synchroniser correctement l'abonnement. Pour plus d'informations, consultez How to: Synchronize a Pull Subscription (RMO Programming).

La spécification d'une valeur false pour CreateSyncAgentByDefault et l'appel de Create équivaut à l'exécution de sp_addpullsubscription (Transact-SQL) sans l'exécution de sp_addpullsubscription_agent (Transact-SQL) ou l'exécution de sp_addmergepullsubscription (Transact-SQL) sans l'exécution de sp_addmergepullsubscription_agent (Transact-SQL).

Cet exemple crée un abonnement par extraction à une publication de fusion, ainsi qu'un travail d'Agent pour synchroniser l'abonnement et les métadonnées relatives.
