Creating Network of Brokers
Hi
I have just installed activemq, I have to start work with failover netowrk
brokers.I dont have
much idea about this can any one explain me regarding this.
I did like this iam not sure iam right.if wrong please help me.
1. I have created first broker like this ,
In the activemq.xml i put these values
<transportConnectors>
<transportConnector uri="discovery:tcp://localhost:61617"/>
</transportConnectors>
<networkConnectors>
<networkConnector uri="static:tcp://localhost:61618"/>
</networkConnectors>
after that i have started activemq it says activemq jms started.
2.I created second broker like this.
I have modified the same activemq.xml by changing <transportConnectors>
and </networkConnectors> values like this.
<transportConnectors>
<transportConnector uri="discovery:tcp://localhost:61618"/>
</transportConnectors>
<networkConnectors>
<networkConnector uri="static:tcp://localhost:61617"/>
</networkConnectors>
and started a activemq in another command window and got these message
INFO faultPersistenceAdapterFactory - Journal is locked... waiting 10
seconds f
or the journal to be unlocked.
when i kill the first activemq process second gets activated.
but iam not understanding where i have to include failover detail ???
these details where i have to include ??
<networkConnectors>
<networkConnector
uri="static:failover:tcp://localhost:61617"/<tcp://localhost:61617%22/>
>
</networkConnectors>
is it in the client program like consumer ??? or in some file, please
expalin
Thanks

If these computers are on the same subnet, the easiest way to get a
network of brokers operational within minutes is to simply use the
default configuration which uses multicast. Below are the
instructions:
1) From host one, cd into the examples directory and run 'ant
producer'. This will send 10 messages to a queue named TEST.FOO.
2) From host two, cd into the examples directory and run 'ant
consumer' This will receive the 10 messages from the queue named
TEST.FOO.
Only once this works properly would I suggest changing the
configuration to something more custom. This ensures that the network
of brokers is, in fact, working correctly before any customizations
take place.
I always use this method when setting up a new network of brokers just
to ensure that everything is OK. Two days ago I set up a new network
of brokers using the default settings and discovered a networking
issue that had to be fixed before the network of brokers would operate
correctly.

I tried the above iam getting some errors, because my network of brokers not
working .
i created one first system like this inthe first comuter
<transportConnectors>
<transportConnector name="openwire" uri="tcp://localhost:61616"/>
</transportConnectors>
<networkConnectors>
<networkConnector name="host1 and host2"
uri="static:/(tcp://localhostsecondsys:61616,tcp://localhostsecondsys:61616)"/>
</networkConnectors>
and second like this in the second computer
<transportConnectors>
<transportConnector name="openwire" uri="tcp://localhost:61616"/>
</transportConnectors>
<networkConnectors>
<networkConnector name="host1 and host2"
uri="static:/(tcp://localhostfirstsys:61616,tcp://localhostfirstsys:61616)"/>
</networkConnectors>
when i test this appication from first computer i cannot see the message
info in the second computer. can any one help me
how to do it with an example.
thanks

Make sure your ports are not conflicting either. Currently I see that
you have clashing port numbers between the two brokers as well. You'll
need to rectify this to get two brokers running on the same machine.
This includes uncommenting the managementContext element and
specifying a different JMX port number for each broker.
Also, for ease of reading logs and debugging, assign each broker it's
own name in the brokerName attribute of the broker element.

It seems you are trying to run two instances of ActiveMQ from the same
installation.
And they are both trying to write to the same journal ... change the
configuration to use a different journal location for the second broker.
