Firedac TFDEventAlerter 和 Firebird 4.0

我正在尝试使用 Delphi 10.4 中的 Firedac TFDEventAlerter 来处理 Firebird 4.0 数据库的事件。这可能吗？

在 Firebird 2.5 中一切正常，但与 Firebird 4.0 结合使用的相同代码不会响应 post_event()。

我还没有尝试过Firebird 3.0。我使用 fbClient 4.0.1.2692

我将客户端应用程序复制到运行 Firebird4.0 的服务器，并且可以正常工作（！）。事件是否使用不同的端口？我想，如果客户端能够连接到数据库那就足够了。

正如 Arioch 所建议的，我查看了 firebird.conf，并看到以下内容：

# The TCP Port Number to be used for server Event Notification
# messages.The value of 0 (Zero) means that the server will choose
# a port number randomly.
#
# Per-connection configurable.
#
# Type: integer
#
#RemoteAuxPort = 0

因此，我想，我必须选择一个固定端口，并在防火墙中打开它。

I am trying to use the Firedac TFDEventAlerter in Delphi 10.4 to handle the events of a Firebird 4.0 database. Is that possible?

With Firebird 2.5 it all works fine, but the same code in combination with Firebird 4.0 does not respond to the post_event().

I have not tried it with Firebird 3.0. I use fbClient 4.0.1.2692

I copied the client application to the server where Firebird4.0 is running, and that works (!). Is it so that the events are using a different port?
I thought, if the client can connect to the database that should be enough.

As Arioch suggested, I took a look at firebird.conf, and see the following:

# The TCP Port Number to be used for server Event Notification
# messages.The value of 0 (Zero) means that the server will choose
# a port number randomly.
#
# Per-connection configurable.
#
# Type: integer
#
#RemoteAuxPort = 0

So, I suppose, I have to choose a fixed port, and open it in the firewall.
