UniDac 8.4.3 - TUniAlerter + Firebird + Events - "Failed to establish a secondary connection for event proccessing"
Posted: Tue 18 May 2021 11:55
Hi everyone,
I'm trying to use TUniAlerter(UniDac 8.4.3) to receive Event from a Firebird Database Server.
I just dropped three components on the Form(TUniConnection, InterbaseUniProvider, TUniAlerter)
did the correct setup for TUniConnection to by ready to connect to DB server and added
OnError and OnEvent Handler and this Code:
I already changed Firebird-Server configuration to a "fixed" "RemoteAuxPort" to avoid any firewall problems.
Any thoughts ?

Code: Select all
procedure TForm1.Button2Click(Sender: TObject);
begin
if not UniConnection1.Connected then
UniConnection1.Connect;
if not dbEvents.Active then
dbEvents.Start;
// some seconds after calling start i get an exception:
// "Failed to establish a secondary connection for event proccessing"
end;
Any thoughts ?
