Store and Forward reconnect failures
------------------------------------
Key: AMQ-968
URL: https://issues.apache.org/activemq/browse/AMQ-968
Project: ActiveMQ
Issue Type: Bug
Components: Broker
Affects Versions: 4.0.2
Environment: All
Reporter: Andy Piper
Attachments: jmstest.zip
For the AMQ reconnection issue, I think it is caused by client can not stop the
broker correctly after server broker is stopped.
Attached zip is the test case, it is an IDEA prj, to compile or run it the
incubator-activemq-4.0.jar (download from
http://people.apache.org/repository/incubator-activemq/jars/incubator-activemq-4.0.jar
) should be involved. In the prj, I added two run configurations: Client,
Sever to try all kinds of connection scenarios below:
1. Start client, then start server
2. Start server, then start client
3. Restart client
4. Restart server
5. Stop server, then stop client, after that restart server again, then restart
client
All scenarios will be successful if using the run configurations in IDEA, but
if we run the server and client in DOS command line, we will find the #5 is
failed.
Here is the reason, if the server broker is stopped, the client can not be
stopped using CTL + C, and the interrupt signal is always only captured by the
client broker rather than its JVM. In this time, if we restart the server, no
any messages can be received again. But the messages in client can not be lost,
after killing the client and restarting it, the messages can be still sent to
server.
So to the scenario in Domain Log, the managed server must be killed by kill-9
shell and can not be stopped by shutdown.bat (sh) script.
Uuuuuunfortunately, the scenario #4 is still failed in Domain Log though the
codes are same with above test case's (it IS successful in the test case). I
can not get the reason after I struggled for it the whole day :(. I am not sure
if the AMQ network connector is impacted in Tomcat runtime env.
