Thread: application handing on send

application handing on send

From

Date:
My tomcat application occasionally hangs trying push data to the
postgres backend.  When I view the connection to postgres with netstat I
see data sitting in the sendQ on the socket.
There is a firewall (cisco pix) between the tomcat server and the
database server.
I was wondering if there is some way to set the timeout on the driver as
to force a IO exception and terminate the jdbc request.

Question to my own question:
 Is there even such a mechanism in the Socket class to do a timeout on a
write?

Socket.setSoTimeout(int timeout) will do this on most platforms. Once set, any
blocking read will throw a java.net.SocketTimeoutException (subclass of
java.io.IOException) when the read times out. Like I said, this doesn't work on
*ALL* platforms, but I think Windoze and Linux are supported.
