Override parameters may be given a specific value, or the special value *SERVER, which indicates that the server default should be used. As an example, a Windows client using DBII=*NONE might connect to a Windows Server running SQL Server. If, by default, Windows uses the database type SQLANYWHERE, DBUT needs to be overridden. The X_RUN exceptional argument value could be set to either DBUT=MSSQLS or DBUT=*SERVER.
This property is in the Server Details tab.
