> Improving reliability of servicemix-jms - servicemix looses messages when

> Key: SM-555
> URL: https://issues.apache.org/activemq/browse/SM-555
> Project: ServiceMix
> Issue Type: Improvement
> Components: servicemix-jms
> Affects Versions: 3.0.1
> Reporter: Klaus Alfert
> Assignee: Guillaume Nodet
> Priority: Critical
> Fix For: 3.2
>
>
> ServiceMix can loose (incoming) messages during a crashing.
> The test-setup is simple: one process populates a queue, servicemix reads
> this queue and writes each message in a second queue, which is consumed by a
> second process. During this test servicemix is killed and restarted.
> My test results showed that some times some messages are lost. Looking in the
> source code reveals that reading from the queue is done with an
> AUTO_ACKNOWLEDGE, which implies that there is no dependency between doing an
> (implicit) commit on the queue and successful sending of a message to another
> JBI endpoint. Apparently, this can result in lost messages if servicemix
> crashes. I could possibly use the JCAProcessor, but then I need an external
> transaction manager.
> I suggest to extend the servicemix-jms binding component with the
> (configurable) ability to make the read of an input queue dependent on the
> successful NMR send. This would add more realiability to servicemix, if
> needed, payed with a (small) loss of effeciency for wating on receiving a
> DONE as MessageExchange status.
