Commenti

Chiama il Synchronize metodo sull'oggetto restituito TransSynchronizationAgent per sincronizzare l'abbonamento.

Dovresti chiamare CommitPropertyChanges per salvare eventuali modifiche alla proprietà sul server prima di recuperare SynchronizationAgent per sincronizzare l'abbonamento.

Se l'abbonamento viene creato con un valore di false per CreateSyncAgentByDefault, non viene creato un lavoro agente di distribuzione per l'abbonamento. Potresti dover specificare proprietà aggiuntive sull'oggetto restituito TransSynchronizationAgent prima che possa essere usato per sincronizzare l'abbonamento.

La SynchronizationAgent proprietà può essere recuperata solo dai membri del sysadmin ruolo di server fisso presso l'Publisher, dai membri del db_owner ruolo di database fisso nel database della pubblicazione, o dai membri della publication access list (PAL) per la pubblicazione a cui appartiene l'abbonamento.

Recuperare SynchronizationAgent è equivalente a eseguire sp_helpsubscription (Transact-SQL).
