Subject Re: Master/Slave configuring clients
Date Tue, 05 Jul 2011 15:24:56 GMT
I am rephrasing my question for get rid of confusion.

We have a Converter app (Standalone JMS consumer client based on Spring
DefaultMessageListenerContainer) which will consume messages from AMQ Broker
hosted on same server. An upstream system will publish messages on to
"TEST.FOO"  Q on this broker. Whole purpose of convert app is to transform
the message to another format and send it to downstream system for further
processing.


Server1 (working fine)
-----------
Consumer App
Regular AMQ Broker

We verified this to be working fine with a consumer, AMQ broker on the same
server.

For redundancy we want to  use Master/Slave Broker config + deploy one more
Consumer app on server2.  This is the new config we have.  But this seem to
be causing message loss. I am attaching a Junit test case to reproduce this.

Server1 
-----------
Consumer App 1 listening to tcp://server1:61616
Master AMQ Broker (tcp://server1:61616)

Server2 
-----------
Consumer App 2  listening to tcp://server2:61617
Slave AMQ Broker (tcp://server2:61617)



Attached is the JUnit test case:
Steps
1. start master on 61616
2. Start slave on 61617
3. start consumer 1  to listen to tcp://host:61616
4. Start consumer2 to listen to tcp://host:61617
5. produce 30 msgs 
Notice only part of message being consumed by listener 1
6. kill master and listener1
7. produce 50 msgs 
Notice only part of messages being consumed by listener 1
7.kill slave

May I know what's wrong with this test case?
