In our project we are using activemq with mysql as external database. we
enabled mirror queue in the activemq.xml file.but still it does not save the
messages or topics in the broker. there are only 3 tables namely
activemq_acks,
activemq_msgs,
activemq_lock.
is it not working or wherev th
thanks again. but one prob my activemq_msgs table is not showing the
destination_id column.
and it only contain the reference of the message.

Hi Johan,
i have not changed any thing in the configuration for data storage.So by
default it might be taking Memory for storing any data.
I simply used the failover in config file as follows? Is there any thing
else i should do or take care for failover?

How did you setup failover?
Did you test that the brokers actually lock on either a file/memory/db-table?
Visually - the DB setup is the easiest to see, you'll see a table lock in
effect on the slave broker
and that it is not starting.
Are you possibly confusing persistence with HA?

i have set up the clients for fail over as i mentioned in the previous posts

Did you setup the clients to have failover capabilities?

Can i get any help regarding this fail over problem?
Its very urgent for me. Plz dont mind.

Think Gary answered this for you in another thread, but in case you
missed it in the activemq_msgs table there's a column that has the
destination ID, this is for either topics or queues.

thanks stan for ur help.. but i want to know where the topics are created in

the message table is shared across all destinations, one of the
columns contains the destination id.

You understand correctly, only unreferenced files are reclaimed. Often
using smaller journal data files makes cleanup more immediate (as the
chance of a slow message being in every data file decreases) but in
your case it may makes sense to increase the max data files if you
cannot increase the max
All of ActiveMQ's messages are stored in that activemq_msgs table, at
least when you're sending persistent messages. Create a durable
subscription on your topic and send some persistent messages to it,
you'll see new entries get added to activemq_msgs. Note that once a
message is ack'd it's remov

Do the topics are saved in the activemq database itself or we have

Thanks. I will work on this as soon as I can.
I submitted a change to the addListener() function in amq.js in https://issues.apache.org/activemq/browse/AMQ-2874
. I added a 4th argument which allows a user to specify a selector.
addListener( 'handlerName', 'topic://test', function(msg){ /*

Hi,
I've been trying to debug an odd sequence problem. I've written a
basic test case in PHP using the stomp connector.
First script adds ten numbered messages (indexed from 0) to a test queue.
Second script receives from the queue and spits them out.
They arrive in the order: 1, 2, 3, 4, 5, 6,

Hi All,
I'm using pyactivemq as both a producer and consumer of messages which are
being brokered by ActiveMQ 5.3.2. In the past I used python stompy to produce
messages and java ActiveMQ to consume them. I need to set a prefetch policy of
1 messgae at a time and more importantly use individu
yea, google tcp buffer size to get some more info, the defaults are OS specific.
Also note the failover: transport compensation of potential message loss.

Thanks for that Gary, that was very helpful.
One more silly question (I don't know very much about networking): does this
mean that if we know the minimum size of our messages and the size of the
tcp write buffer, it would just be a matter of dividing the buffer size by
the minimum message size
you need to pass the selector into the call to createConsumer. Have a
look at the activemq virtual destinations or filtered queue feature,
this will allow you you to configure named queues that match a
selector, all in configuration. You clients just need to pick the
corresponding destination name
Hi Bob,
there's no such option at the moment.
This the best solution for your test case would be to use the same
clientId on all machines and use prefetchSize of 1 as explained here
http://activemq.apache.org/rest.html#REST-Consuming
I'll see to put some love in the REST API in the coming days.
note that the xml configuration is validated against the schema in 5.4
and order of the elements in the broker sequence is important. check
the order if you get xml parse errors after the upgrade if you reuse
your config.

It is not possible to put an exact number on that as it depends. It
would be limited by the tcp write buffer in the worst case scenario so
will depend on the message size.
Imagine, the broker is loaded so cannot read fast enough, the client
writes as fast as it can till it blocks on a socket write,
note, the issue you raised has been resolved for 5.4 and there is a
workaround identified in the jira.

We are using the "jms.useAsyncSend=true" option on the connection factory to
force persistent messages to be sent asynchronously. This means our client
does not wait for an acknowledgement from the server after sending a
message. Our clients are on a different host from the JMS server.
Async send
Can you try using keepAlive option and see if that helps?
Cheers
