Hi TIm,
thankyou for your reply.
we have first activemq server where we store messages on some abc queue. our
client want same abc queue data from first server to second server xyz
queue.
just want move same data to some other activemq server . if could give some
info on this it could be more
Hi Everyone,
in one of our project we are suffering for ActiveMQ performance degrade when
we use the schedule facility (enabling schedulerSupport in ActiveMQ
configuration) with high amount of message (1M or more). We are, also, using
Camel for route management.
Our routes are configured as

I have used transport.socketBufferSize=x in transport connector broker A

Hi,
We are using ActiveMQ-5.11 with kahadb shared storage. I just want to
understand the aspects of using JDBC for persistence store.
I know that kahadb is the default database for ActiveMQ and JDBC was used
with old versions. Does ActiveMQ gods suggest using JDBC in ActiveMQ ?
Thanks,
Anuj
I am able to use virtual topic and solve the issue..
In case of subscriber i have to use queue instead of Topic and use this
queue for consumer. Suppose we should not use durable subscriptions.

I believe I've seen someone (I'd guess Tim or Art off the top of my head)
give rough performance comparisons between JDBC, KahaDB, and LevelDB, but
searching my email quickly I couldn't find it. So I'll just say that the
consensus is that you'll get the best performance from LevelDB, then
KahaDB,
You could use mirrored queues (
http://activemq.apache.org/mirrored-queues.html) and Camel routes that
consume from the mirrored queues and publish to the other broker's real
queues.
To make that work, you'll need to set up your Camel routes on one and only
one broker along the path each message
Researching the question that josealvarado recently posted (
http://activemq.2283324.n4.nabble.com/How-to-forward-a-topic-using-network-of-brokers-td4696688.html#a4696745),
I came across some seemingly contradictory guidance about how to bridge
virtual topics, and I'm hoping that Dejan (who
I thought about it some more and I think I misunderstood the statement at
the bottom of http://activemq.apache.org/virtual-destinations.html. I
believe that guidance says that you should always include
Consumer.*.VirtualTopic. unless you have a consumer directly on the
destination itself (that is
Actually, try this instead:
networkConnectors
networkConnector name=linkToBrokerB
uri=static:(tcp://localhost:61616)
dynamicallyIncludedDestinations
queue physicalName=/
topic physicalName=/
/dynamicallyIncludedDestinations
/networkConnector
How did using a virtual topic allow your consumers to selectively receive
only some of the messages destined for them?
If you don't use durable subscriptions, you'll still consume messages as
usual. The only difference you'd see is in the behavior if you
disconnected your consumer and
Wait, what? I thought your configuration was topic
physicalName=PRICE.STOCK./; where did virtual topics come from? Maybe
you should describe exactly what you're actually doing, to avoid any
confusion...
If you configure
networkConnectors
networkConnector name=linkToBrokerB
You're right, I didn't catch that in your original message, sorry.
What did you find when you investigated my suggestions about the TCP
congestion window and your OS's max socket buffer size setting?
Also, have you confirmed that a non-ActiveMQ TCP socket connection can get
better throughput?
I just realized: since the queue on the other broker has a different name,
you can use a composite destination to get a copy of the message into the
xyz queue on your main broker, and federate the two brokers and use normal
message forwarding to get them to the consumers on the other broker.

I just upgraded to 5.11.1 and everything seems to work except for the Web
Console.
When I log on there is no data in the Main page Broker or any queues,
topics, etc.
The page is there just no data.
I checked and double checked the conf and can't seems to find anything.
Thanks

I've had a dev cluster running for a little while now and twice I've seen
interruptions where the cluster didn't recover, didn't select a new master.
I had hoped AMQ-5082 fixed that issue but it looks like there might be
additional problems. How many of you folks are running replicated leveldb,
The current version of ActiveMQ doesn’t really scale well over say
1000-2000 queues (if you GC them).
If you create one queue per client then you will have lots of queues.
I haven’t submitted my patches yet (trying to port our code to 5.11) but it
should resolve that situation.

In case i want to send message to particular consumer, i have changed my
producer code to send the message to consumer's queue directly not to the
virtual topic.
Thanks

Hello,
The best way to get a list of topics and queues is by using the Statistics
Plugin on the broker. Check the documentation here:

Dear list members,
I am trying to understand the performance profile of ActiveMQ. Let's assume, we
have some 500 clients sending the same type of messages (status updates) to one
single central server - basically a windows service that interacts with a SQL
database on the same machine. Which
