Commenti

La MaxDistributionRetention proprietà specifica il periodo massimo di conservazione prima che le transazioni vengano cancellate. Gli abbonamenti che non hanno ancora ricevuto comandi replicati e più vecchi del periodo massimo di conservazione della distribuzione sono contrassegnati come inattivi.

La MaxDistributionRetention proprietà può essere recuperata solo da membri del db_owner ruolo di database fisso replmonitor o fisso nel database di distribuzione, dagli utenti nella publication access list (PAL) di una pubblicazione che utilizzano il database di distribuzione, o da utenti con permesso SELECT nella tabella di sistema MSdistributiondbs nel database di distribuzione.

La MaxDistributionRetention proprietà può essere impostata solo dai membri del sysadmin ruolo server fisso presso il Distributore.

Recuperare la MaxDistributionRetention proprietà equivale a eseguire sp_helpdistributiondb.

Impostare la MaxDistributionRetention proprietà equivale a eseguire sp_adddistributiondb o sp_changedistributiondb.
