Parametry
- businessLogicHandler
Typ: Microsoft.SqlServer.Replication.BusinessLogicHandler
A BusinessLogicHandler obiekt reprezentujący obsługa logika biznesowa , zarejestrowana.
Uwagi
Obsługa logika biznesowa muszą być zarejestrowane na dystrybutora (i subskrybent w odniesieniu do subskrypcja wciągana).Jednakże zgromadzenie który implementuje obsługa logika biznesowa należy zainstalować tylko na serwerze, na którym uruchomiony jest Agent scalania.
RegisterBusinessLogicHandler(BusinessLogicHandler) Metoda może być wywoływana tylko przez członków sysadminstała rola serwera i db_owner stałej rola bazy danych
Wywołanie RegisterBusinessLogicHandler(BusinessLogicHandler) jest równoważne wykonywanie sp_registercustomresolver.
RegisterBusinessLogicHandler(BusinessLogicHandler) Metoda może być używany tylko z serwerami, które są uruchomione na SQL Server 2005 i nowsze wersje.
