delivery channel get stuck
Hi all ,
For a single request in my requirement using JBI components iam in need
of using four jbi components like jms, bpel, xslt-in, xslt-out etc. At one
point of time when i send a request it is not processing it get stuck. And
after some time when i shutdown my tomcat server then i get the error states
that Deleivery Channel has been closed. My Question is are below
1. How many request can a Delivery channel process it.
2. What is the maximum size of the Messge Exchange content, while sending it
to another component.
regards,
shahm

Well if you're using multiple servicemix.xml files, it sounds like
you're using lightweight components. This is not where you configure
the thread pools. These are configured in the conf/servicemix.xml file
which controls the entire ServiceMix container.

Did you add the EIP wiretap as I suggested in another one of the
messages you posted to this list? This will allow you to route the
message to an endpoint where you can view it to be sure it's making it
that far.

The java.util.concurrent queues in the SEDA flow can fill up but only
under heavy load. When this happens, tuning the thread pools is
exactly the solution.

I'm not sure why it's happening. Have you enabled debug level logging
in ServiceMix to see if there's anything in the logging that would
indicate an error or something?

This depends on the flow being used, the components being used, the
size of the messages, presence of attachments, etc. Also note that
components can be tuned via the thread pools to scale them further:

There is no maximum message size per se, it's more of a product of the
components being used and the resources you have available.

This reason you're not seeing the number of threads decrease is
because you have explicitly configured it to be 32. The corePoolSize
is used to configure a java.util.concurrent.ThreadPoolExecutor
(http://java.sun.com/j2se/1.5.0/docs/api/java/util/concurrent/ThreadPoolExecutor.html)
and serves as the lower boundary for the number of threads to keep
alive in the pool. I *highly* encourage you to read the Javadoc for
the ThreadPoolExecutor to understand how it works as I think this will
alleviate most of your questions above. After reading that, please let
us know if you have anymore questions.
BTW, there are much newer releases of Fuse available for download:
