JC,
I tested the work around and a listener to the delegate is indeed
recreated. The CAS that were being processed pass through all annotators.
But now I have other issues, but it is not the same each time I tried
.Either the client is losing connection, or get block on the getCAS
method as if cas process during the JMS down time were not release or
the aggregate or the aggregate client get stalled...
I need to dig a little bit into this because it does not make many sense
right now...
What bother me is that if I don't make the annotator delegated, the
aggregate client always recover clean with this scenario.
Anyway Thanks
Pierre

Pierre, in my last posting I meant maxRetries=1, not retryCount=1.

Pierre, I've identified the bug in UIMA AS code that causes the problem
described. As a workaround, set the retryCount=1 in the error handling
configuration for the delegate defined in your deployment descriptor. Here
is an example:
<remoteAnalysisEngine key="NoOp">
<inputQueue endpoint="NoOpAnnotatorQueue"
brokerURL="${BrokerURL}"/>
<serializer method="xmi"/>
<asyncAggregateErrorConfiguration>
<processCasErrors maxRetries="1"
timeout="15000" thresholdCount="1" thresholdAction="terminate" />
</asyncAggregateErrorConfiguration>
</remoteAnalysisEngine>
This should force creation of a new listener on the delegate reply queue.
The listener recovery should be done with no retry being set and I will
make necessary changes in the code to support that use case.
Thanks for finding the bug!

Pierre, this appears to be a bug. In the scenario you've described the
uima as aggregate client should detect a lost connection (which it does) and
create a new one on a subsequent process CAS request destined to the remote
delegate. I will attempt to re-create your scenario and see if this is in
fact a bug.
Thanks, JC

Hi,
I'm currently using UIMA-AS 2.3.1rc5 and I am having issues with
asynchronous delegated ..
I have a chain of several annotators. One of them is an asynchronous
delegate as it is very resource consuming.
So I have one UIMA service with a simpleChainDescriptor and several UIMA
services with myDelegateAnnotatorDescriptor.
When the activeMQ broker fails and restart, all my UIMA services
resfresh succesfully their JMS connection. But it appears that the service
holding the processing chain (simpleChainDescriptor) itself does not
refresh the JMS connection to the delegate JMS queue.
When a new CAS is processed, I have the following exception in the
console !!!! and the processing of the cas stop silently and passes to the
next cas.
If I restart the service holding the chain, everything go back to
normal.
Is this a bug or am I missing something?
Thanks,
Pierre
