Do you have problems with InterBase event alerters?

Original text


Problem desription:

Are there any known problems with IB events on the Windows 9x platform?

After a certain amount of events the TIBEvents component stops triggering the OnEventAlert event. After disconnecting and reconnecting to the db, the events work again. But the Win 9x OS becomes unstable. On the NT platform the application seems te become unstable after tens of thousend's of events.

[Statistics]

Windows 95: 1118 events (yes, I know it's unsupported).
Windows 98SE: 8191 events.
Windows 2000 Server: many many events.
Windows 2000 Pro: many many events.

A work around:

Connect the TIBEvents component to its own database connection component. And Close+Open the database connection after each 400 events.

An even nicer solution is to use two TIBEvents each having there own connection, and then use a thread to toggle between them after each 400 events.


Cheers,
Erwin
