Hello Eddie,
Once again thanks for replying.
I tried removing the collection reader.. this thing now works the same
way it worked in my CASE 2* .
The main thing I am concern with that in this case I need to send a
loads of data over the net.. can't there be a way by which I could have
rested my data on machine hosting the remote service.. and would have
called my client without a collection reader.. or either providing only
reference or some thing so that my network traffic could be lesser n
processing be bit faster?? as i would practically never want to download
the data first to client from my database and then sending it to remote
machine..
Secondly, when I define the the collection reader with the remote
service and it even have data in the local system... what makes the
processing go extremely slow?? indeed I was expecting it to be more
faster... am I wrong somewhere??
Regards,
Lokesh

Lokesh,
The scenario in figure 3 uses a collection reader at the driver, and
no collection reader in the remote service. Please try that.

Eddie

Hello Eddie,
My situation is quite similar to fig 3 but i m using only one queue, one
service and one runRemotAE instance.
My deployment descriptor is as follows:
/<?xml version="1.0" encoding="UTF-8"?>

Sorry, it is a bit hard to understand your scenario. Please clarify
using the examples
inhttp://uima.apache.org/doc-uimaas-what.html and identify which best
fits your situation,
Figure 3, 4 or 5.
Thanks,

Hello,
I am deploying UIMA-AS for testing perpose by now.
My configurations includes
!. Broker on one system<say Broker>
2. Service on one system<say Service>
3. Client on one system<say client>
My configuration
=> my deployment descriptor calls the flowControlAggregate.
=> Flow control defines 3 delegates
1. collection Reader that reads data from
/opt/apache-uima/examples/data
2. my core analysis Engine that process the data
3. XmiWriterCasConsumer.xml class to generete output.
i deployed them as
<On Broker> startBroker.sh
<On Service> deployAsyncService.sh /Path/to/deployment/descriptor.xml
-brokerURL tcp://<BROKER>:61616
<on client> runRemoteAsyncAE.sh tcp://<BROKER>:61616 MeetingFinderQueue
-c
/Path/to/collectin/reader.xml -o result.xmi
NOW the problems i m concerned about are...
If I don't define collection_Reader then i get no error but it says only
one
file is processed. (I knw that it is due to fact that client send an
empty
CAS). this means that client is sending the data in form of CAS. if so
then
y a cas collector if compulsaryin my flowControlAggregator???i tried
emoving
it but the service didn't started.
I found one answer to this that CAS at client is just sending the
reference for CAS at SERVICE.
To test this i deleted the whole data at
SERVICE(/opt/apache-uima/examples/data).
Unexpectedly my processing time got reduced to some 20 sec. (which was
earlier 3200 sec. for 500 documents).
now i have two cases
case 1: when the data at client and service is same.
processing is too slow.
xmi file ganerated are of shoter length
the XMI files are different then those created by the basic UIMA
application
processing at SERVICE is too high
neglegible processing at client.
case 2: when the data there is no data at SERVICE end
Processing is fast
XMI are same as those creaed by local uima.
no much proocessiong either on client or SERVICE end.
Now as things are not as i expected I am sure i m somewhere wrong
conceptually. As i am quite new to UIMA-As any help is apprecable.

Lokesh
