How to create connections to different brokers by using one
ConnectionFactory?
Can the code be written as
ActiveMQConnectionFactory connectionFactory = new
ActiveMQConnectionFactory();
for each url in URLs {
connectionFactory.setBrokerURL(url);
Connection connection = connectionFactory.createCon
Thank you very much!
I am sure the log4j.properties loaded by my client program is the one I am
editing.
but failover connection INFO logging still comes out.
could you show me an example log4j.properties file content which can work ?

I want to connect the client application to multiple brokers, then I can
balance the message sending to different brokers.
Now I use the method of creating multiple connection factories in the
client, each with different connection uri.
that is.
for(uri in uri1... uriN) {
new ActiveMQConnectio
Could anyone give an explanation about the detailed process of sync sending
and async sending in ActiveMQ?
Especially for sync sending, is it the synchronization between sender and
broker, or the sender and receiver?
And what will happen if you send message across a network of brokers?
Thanks.
Could it be possible that the process of propagation of the subscription to
all brokers is asynchronous and takes long time?
As a result, the broker which directly connects to the sender doesn't know
how to forward the message?

The main problem here is that it is really hard to repeat.
I am using a network of brokers for large distributed application.
Message loss happens about 2% of total execution times.
That is I execute 100 times of my application, may be 2 times, message lost
could happen.
Do you have any suggest
message lost under persistent and sync sending mode,
according to many documents, persistent and sync sending mode should be
reliable.
How to resolve this problem?

If I do sending in onMessage function under persistent and sync mode.
Is it fine?
Will it cause deadlock in some cases?
Or should I create a new thread to do sending?

for producers, we can use non -persistent sending mode by the following
code,

But how about MB level sized message?
I have to change the way of sending based on the message size.
Thanks

Or what is the biggest size of the message which can be sent through

But I tried to use the same broker name.
Everything looks proper.
So I am thinking if the broker names are not required to be different now.
If it is true, configuration for multi brokers will be much easier.
