Re: JDBC-System or internal error java.io.IOExcept

In Response To: Re: JDBC-System or internal error java.io.IOExcept (KARTHIK RAJAN)

I meant the error on the client. Usually Java throws an exception with a
stack trace. In there it should be possible to see one Informix error.
Is your application hiding the stack trace?
It's possible you're facing:

-79716 System or internal error.
An operating or runtime system error or a driver internal error
occurred.

The accompanying message describes the problem.

This is usually caused by a broken socket... very usual with firewalls.

Besides fixing what is breaking the connection, the only option I see
is to change the application and when this happens try to reconnect.

Regards
