SUMMARY:
An inactive publisher and subscriber cannot detect that a broker might be disconnected from the network because no TCP_RESET is sent. This solution explains how to solve the problem.
SOLUTION:
In Progress SonicMQ 2000, there is a feature that allows an
application to examine the health of the connection by pinging the broker on a JMS connection:
setPingInterval(interval)
Interval is in seconds, and a zero or negative value
turns off the ping if it is already on.
When you invoke setPingInterval(interval) on a connection, a ping message is sent to the broker on that connection at the specified interval.
NOTE: Setting an interval too small burns up too much bandwidth which may bog down your application.
