ActiveMQ 5 requires Java 5 - so this won't be a problem for AgentSmth
We just need to override the Smith.redefineClass() method in a
derived class to add some eventing to stop the routes and reload the
classes

Any updates on making this easier? Am not a .NET guy. Ideally something like
typing in an Excel cell:

:-)
Thanks.

Here's what I read about AgentSmith.
1. It has an implementation of the java.lang.instrument.Instrumentation
interface and it also has a file monitor.
2. It has the ability to monitor predefined list of folders for changes to
classes. It can also monitor jar files.
3. It needs atleast Java 5 to r

I've add setUseAsyncSend(true) to connection factory and the performance
boost to 2k-4k/sec using my notebook depend on CPU idle. ActiveMQ is very
robust. My problem resolved, many thanks for the help.

I haven't done any performance test by now (besides testing some
sending/receiving stuff in my notebook), but you sure can understand that I
must provide a Scalability Guide to my customer, so even if I can process
"one hundred million messages a second", I need to provide him with a guide

Something like 860 KB/sec of text encapsulated into JMS messages of about 150
bytes each one, coming from 42 machines. The problem is that we need to do
some parsing of the messages on the machine, and that the number of clients
could potentially grow. That's why we need some brokers to be Master.

Note that a slave does not have to run on the same machine as its master.

I can't think of a reason why you couldn't have each of the three be a
'master' w/a corresponding slave. This is the kind of cluster topology I
thought you were after.

Note that "network of brokers" usually means a store and forward
network traditionally, which is not a master/slave cluster which is
what you probably want.
BTW what kind of load do you need? I suspect a single master/slave
cluster of brokers is all you need.

Thanks, Joe. Only a few more questions:
Can't I have brokers that are all of them "Master" brokers? I need all of
them to be active, but provide a backup for the other brokers.
So if I have:
- Broker-1
- Broker-2
- Broker-3
All the 3 brokers are active and receiving messages from producers, and
ActiveMQ gives you this capability via the Pure, Shared File System, or JDBC
Master/Slave configurations.
These configurations allow you to set up a network of brokers that is
comprised of 'master' brokers, where each master is backed up by one or more
passive 'slave' brokers. If a master were to
Hi,
I have been reading the ActiveMQ documentation but something isn't entirelly

I need to setup a network of brokers with the following requirements:

- I need that if on
Hi,
Please can you tell me if its possible to attach to the message the

cause of their failures.

Thanks for the quick response.
I was looking at both JavaRebel and AgentSmith. JavaRebel seems to have a
very restrictive license agreement which may never fit into the Apache
License of ActiveMQ.
AgentSmith looks promising and it uses Apache License 2.0. I would look into
it and see if I can co

Hi,
I'm using ActiveMQ 5.0 snapshot version that has Camel integrated. I've
defined some Camel EIP routes using Java. I created a jar and dropped it
into the $ACTIVEMQ_HOME/lib folder. All the routes I've defined in there
work perfectly fine.
However, if I want to change any of those routes, can
We had the same problems using AMQ-4.0.2 as well. We were able to reduce them
by applying the patch described in
https://issues.apache.org/activemq/browse/AMQ-961, which only seems to have
been applied to trunk, but not yet to the 4.1.x branch.

You can also use Camel as a Spring Remoting implementation which will

Also if you don't want to block until each message has been written to
disk before sending the next one, you could use async sending which
boosts performance a fair bit.

Ur sender code looks fine to me, are u sure ur messages are not being
persisted by ActiveMQ.
Persistence can slow down send considerably. Check ur ActiveMQ config file
for persistence.
