Hinweise

Der Geschäftslogikhandler muss beim Verteiler (und beim Abonnenten im Fall eines Pullabonnements) registriert werden. Die Assembly, die den Geschäftslogikhandler implementiert, muss jedoch nur auf dem Server installiert werden, auf dem der Merge-Agent ausgeführt wird.

Die <xref:Microsoft.SqlServer.Replication.ReplicationServer.RegisterBusinessLogicHandler%2A> Methode kann nur von Mitgliedern der sysadmin festen Serverrolle und Mitgliedern der db_owner festen Datenbankrolle aufgerufen werden.

Das Aufrufen <xref:Microsoft.SqlServer.Replication.ReplicationServer.RegisterBusinessLogicHandler%2A> entspricht der Ausführung sp_registercustomresolver.
