Subject Re: UIMA AS: Invalid destination after broker restart
Date Thu, 16 Feb 2012 10:50:16 GMT
Jerry, after disassembling our client, pipeline and broker configuration
I finally found out what's causing troubles:
When working with old AS 2.3.0 (and AMQ 4.x) we were used to work with a
failover transport
(http://activemq.apache.org/failover-transport-reference.html) by adding
"failover:" as prefix to the broker URI.
That was recommended, since it was said it would help on recovering from
lost connections when having high message load (even when working with a
single broker and no backup broker at all).
However, when deploying a pipeline using failover transport, this
pipeline shows the behaviour I described above.
I could reproduce it using the MeetingDetectorTaeQueue, which comes with
the UIMA AS bundle.

I have not yet tried whether that affects "real" failover scenarios
(using multiple broker uris) as well.
Does anyone of you have experiences using UIMA AS in a scenarion with
multiple brokers and failover transport?

All the best, Frank
