Comentarios

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

Deberías llamar CommitPropertyChanges para guardar cualquier cambio de propiedad en el servidor antes de recuperarlo SynchronizationAgent y sincronizar la suscripción.

Si la suscripción se crea con un valor de false para CreateSyncAgentByDefault, no se crea un trabajo Agente de distribución para la suscripción. Puede que necesites especificar propiedades adicionales en el objeto devuelto TransSynchronizationAgent antes de que pueda usarse para sincronizar la suscripción.

La SynchronizationAgent propiedad solo puede ser recuperada por miembros del sysadmin rol fijo de servidor en el Publisher, miembros del db_owner rol fijo de base de datos en la base de datos de publicaciones, o miembros de la lista de acceso a publicaciones (PAL) para la publicación a la que pertenece la suscripción.

Recuperar SynchronizationAgent es equivalente a ejecutar sp_helpsubscription (Transact-SQL).
