Comentarios

Llame al Synchronize método en el objeto devuelto TransSynchronizationAgent para sincronizar la suscripción.

Debe llamar CommitPropertyChanges a para guardar cualquier cambio de propiedad en el servidor antes de recuperar SynchronizationAgent para sincronizar la suscripción.

Si la suscripción se crea con un valor de false para CreateSyncAgentByDefault , no se creará un trabajo de agente de distribución para la suscripción. Es posible que tenga que especificar propiedades adicionales en el objeto devuelto antes de que se TransSynchronizationAgent pueda usar para sincronizar la suscripción.

Solo los miembros SynchronizationAgent del sysadmin rol fijo de servidor en el publicador, los miembros del db_owner rol fijo de base de datos en la base de datos de publicación o los miembros de la lista de acceso a la publicación (PAL) de la publicación a la que pertenece la suscripción pueden recuperar la propiedad.

Recuperar SynchronizationAgent es equivalente a ejecutar Sp_helpsubscription (TRANSACT-SQL).
