I have at server set

Code: Select all

wait_timeout	      28800
interactive_timeout  28800
These are default values, and never experienced any problems. Using mysql 4.1.03 up to 4.1.13a. Perhaps you changed this and there isn't really the need to do it.

> I think components should reconnect automatic, like DBX did.

Automatic reconnection is performed but a query not passed to the server again.

In general for cases with unstable connection (GPRS etc) it would be correct to use СachedUpdates along with transactions.

Anyway the problem is solved with ping and biggest timeout.

I think implementing this in new MyDac release would be great.

Thank you GEswin and Ikar.
