Hinweise

Die MaxDistributionRetention -Eigenschaft gibt den maximalen Aufbewahrungszeitraum an, bevor Transaktionen gelöscht werden. Abonnements, die noch keine replizierten Befehle erhalten haben, die älter als der maximale Aufbewahrungszeitraum der Verteilung sind, werden als inaktiv markiert.

Die MaxDistributionRetention Eigenschaft kann nur von Mitgliedern der oder replmonitor festen db_owner Datenbankrolle in der Verteilungsdatenbank, von Benutzern in der Veröffentlichungszugriffsliste (PAL) einer Publikation mithilfe der Verteilungsdatenbank oder von Benutzern mit der SELECT-Berechtigung für die MSdistributiondbs-Systemtabelle in der Verteilungsdatenbank abgerufen werden.

Die MaxDistributionRetention Eigenschaft kann nur von Mitgliedern der sysadmin festen Serverrolle am Verteiler festgelegt werden.

Das Abrufen der MaxDistributionRetention Eigenschaft entspricht der Ausführung sp_helpdistributiondb.

Das Festlegen der MaxDistributionRetention Eigenschaft entspricht der Ausführung sp_adddistributiondb oder sp_changedistributiondb.
