gojoke May 21, 2012 6:55 AM (in response to gaohoward)Thank you for your reply. And sorry that the imformation was not enough.
The version 2.2.5.
I just can not set up the field "min-large-message-size" to increase the size of message transferred between 2 cluster servers.
For more detailed information , I will test it again and get the error messages and configurations.
But from my invetigation , this bug is mentioned in the site below :
https://issues.jboss.org/browse/JBPAPP-7455

difu May 21, 2012 1:00 PM (in response to gojoke)I have a similar problem with min-large-message-size. I tested on both 2.2.5 and 2.2.7, and I could sent large messages over min-large-message-size. My problem is that Sometimes when I finished testing and close the consumer session, I got exception like:
java.lang.IndexOutOf BoundException
at org.jboss.netty.buffer.AbstractChannelBuffer.checkReadableBytes
...
at org.hornetq.core.buffers.impl.ChannelBufferWrapper.readNullableSimpleString
...
at org.hornetq.jms.client.HornetQTextMessage.doBeforeReceive
According to the user manual, min-large-message-size defines the size of a large message and it should not be the cause to your failure. The default value for min-large-message-size is 100K, but this value does not mean that you cannot send and receive messages large than 100KB. This parameter tells hornetq that when a message is larger than 100KB, hormetq should send and receive messages in chunks of at most 100KB and merge these chunks into a message.

gojoke May 21, 2012 9:11 PM (in response to gaohoward)・Test Condition :
4 machine : Producer , hornetQ-cluster A , hornetQ-cluster , Consumer
Version: 2.2.5
OS: Linux
Other Information : running as hornetQ stand-alone
Do the test as following
Case 1 : The configuration of connection-factory without <min-large-message-size>
Step 1: Preprare 2 messages ( 50kb and 150kb), and send them from producer to consumer
Step 2: Confirm the consumer: can receive the 50kb message but lose the 150kb one.
Step 3: Confirm the hornetQ-cluster machine: A waring occured [ removing consumer which did not handle a message, consumer = org.hornetq.core.server.cluster....]
Case 2 : The configuration of connection-factory with <min-large-message-size> at each the cluster machine.
Step 1: Preprare 2 messages ( 50kb and 150kb), and send them from producer to consumer
Step 2: Confirm the consumer: The consumer can receive the 50kb message but lose the 150kb one. (The same with case 1)
Step 3: Confirm the hornetQ-cluster machine: No warning or exception occured.
Case 3 :
Step 1 : In the [ hornetq-configuration.xml] , I added <min-large-message-size> to the <cluster-connections> as below
<cluster-connections>
<cluster-connection name = 'my-cluster'>
...
<min-large-message-size> 31457280 </min-large-message-size>
...
</cluster-connection>
</cluster-connections>
Step 3 : Confirm the hornetq :
Exception : The [Invid configuration] is shown that [ Invid content was found starting with element 'min-large-message-size']

7. Re: Clusters don't support big messages over 100KB?
gojoke May 21, 2012 10:40 PM (in response to gaohoward)OK. I am going to try to test it again at the latest version 2.2.14 and give you a reply.
But now I do not get any information at the release note about this problem. So i think the problem still exists in the latest version.

clebert.suconic May 22, 2012 9:10 AM (in response to gojoke)if you increase the size of min-large-message, you also have to increase the buffer size on the journal, otherwise you won't be able to send these messages.
You should also increase the size of the journal itself. I believe the default journal size is 1M on AS7.s
