Commenti

Chiamare il Synchronize metodo sull'oggetto restituito TransSynchronizationAgent per sincronizzare la sottoscrizione.

Chiamare CommitPropertyChanges per salvare le modifiche apportate alle proprietà nel server prima di SynchronizationAgent recuperare per sincronizzare la sottoscrizione.

Se la sottoscrizione pull viene creata con il valore false per CreateSyncAgentByDefault, il valore predefinito non viene creato un processo agente di distribuzione per la sottoscrizione. Potrebbe essere necessario specificare proprietà aggiuntive nell'oggetto restituito TransSynchronizationAgent prima di poterle usare per sincronizzare la sottoscrizione.

La SynchronizationAgent proprietà può essere recuperata solo dai membri del ruolo predefinito del sysadmin server nel Sottoscrittore o dai membri del ruolo predefinito del db_owner database nel database di sottoscrizione.

Il recupero della proprietà equivale all'esecuzione SynchronizationAgentdi sp_helppullsubscription.
