Re: How to purge or Delete messages from ActiveMq Topic

2009-11-27T00:49:26Z

are you using auto_acknowledge on your session? Issue may be that the
messages are not getting acked if you have a durable subscriber.
Can you post your code?

NPE- Consumer Example

2009-11-26T11:38:28Z

The default sample app in 5.3 is throwing a Null Pointer Exception for consuming the message. I see that message count is decreasing by 1, when i run the consumer sample app for 1st time. But it doesn't consume any more message and throws this NPE. Its on Mac. Any idea?

Thanks,
Uday.

Re: HTTP- Authentication

2009-11-26T11:31:29Z

Thanks. First I need to disable this anonymous access, otherwise any one can POST message to my queue! How do I do it?

Basic auth? hmm...expected a little better here for security!

Best,
Uday.

Hi,

Actually XAConnection is being setup fine but the session is not getting the transaction attributes.
I also tried to ensure your suggestion to extend and override the createConnectionFactory but does not solve the issue. I am listing here the application config (with Override) so that one can refer here if needed.

using derived class config:

I have opened issue as you suggested:
AMQ-2514

There are thus two bean configs in this thread viz. with and w/o deriving ActiveMQInitialContextFactory.

is the problem that the

connection factory reference.
Either through configuration of by default the createConnectionFactory
should be capable of returning an XA connection factory. I think by defaut
it would make sense. Can you raise a JIRA for this an if you find that this
is the root cause of your problem.

Message not sent to consumers after restart

2009-11-26T03:35:18Z

Hello All!

I have strange situation with last activemq and broker restart.

1. Sent 1000 messages to queue. There is 10 threads of consumers.
2. Stop listeners, stop broker. Some messages are in queue.
3. Start broker, start listeners.
4. All messages except 10 are processed. 10 messages are still in queue. Via jmx I saw queuesize = 10, inflightcount = 0;

I debugged jdbcPersistenceAdapter and found that I still had records in database for these 10 messages. Query to get messages is based on id > lastMessageId and all messages in database had id < lastMessageId.

Could anyone explain how it can be. And how it can be fixed?

Thanks!

Re: Managing default persistence data?

2009-11-26T01:47:00Z

If the messages are acked the storage will be reclaimed in time, once the
data file that they occupy is no longer referenced. Verify that your
consumers are indeed doing an ack or transaction commit. The size of the
datafiles and the cleanup/checkpoint period have an effect on this behavior.
Doing a purge will remove pending messages in a queue, messages that have
not yet been consumed, I does not sound like that is what you want.
Are you on 5.3.0?

I have a similar issue with ActiveMQ Broker.I use a jms queue in my project that uses activemq broker.I see that the activemq-data directory becomes huge when there are a log of requests going in into the queue.The requests are read from the queue and sent to a destination.I want the entries to be purged from the activemq broker when a message has been sent successfully to a recipient.I see that the entries can be purged from the jmx console and can delete existing messages on start up.But i want to make sure that i do not delete messages which have not been delivered yet to the destination.How can i do this?

Re: Best implementation for reply-request

2009-11-25T12:24:09Z

there could well be an improvement using nio. Also - it it possible to
move to version 5.3 - which is generally a lot more stable.
Btw - you didn't mention if you were having performance problems ?

cheers,

Bruce thanks for your reply.
The consumers create the temporary queue only once, and they are cached in a pool for subsequent usage.
We are using tcp connection. If we move to nio connection, will there be any noticeable improvement?

There's more overhead involved with such constant creation/destruction
of temp queues, but that's it. As long as the broker has been tuned to
scale for handling such a large number of destinations, then you
should be OK:

The Java client can send and receive messages with compressed message
bodies. The body is compressed using the Java Deflate classes which
work with ZLib compression. In order to send and receive compressed
messages from Java to .NET clients the .NET client needs to be able to
handle Zlib compression as well. We didn't want to tie the user to a
particular compression library with NMS.ActiveMQ so we provide an
interface class that the user can implement to give us access to a
Stream class that can compress or decompress the message body.

If you grab the latest code from SVN you will find an interface called
ICompressionPolicy in the NMS.ActiveMQ project. The default
implementation uses the .NET gzip Stream classes so those aren't going
to work if you want to send to a Java client, you'd need to provide a
new policy class. If you take a look at the MessageCompressionTest.cs
file in the NMS.ActiveMQ test/csharp/Commands folder you will see how
this is done.

Tim.

Hi,

We have currently running apache activemq 5.2 in a network of brokers

It has close to 1500 producers and 1200 consumers.

This producers have each one a temporary queue so that will be 1500
temp queues in the system.

The reply-request is implemented using temporary queues.

I would like to know if there's a performance hit by using temporary
queues instead of using another option.

What do you guys think?

Re: xa jta activemq jboss

2009-11-25T09:19:05Z

is the problem that the
ActiveMQInitialContextFactory returns a regular connection factory rather
than an XA capable one. You may want to extend the
ActiveMQInitialContextFactory to override the createConnectionFactory()
method to return an XA variant or see if you can explicitly provide the
connection factory reference.
Either through configuration of by default the createConnectionFactory
should be capable of returning an XA connection factory. I think by defaut
it would make sense. Can you raise a JIRA for this an if you find that this
is the root cause of your problem.

Re: Creating message from byte[]

2009-11-25T09:12:58Z

Thanks Tim. We are using ICSharpCode (http://www.icsharpcode.net/OpenSource/SharpZipLib/) for end-to-end compression between C#/Java clients using TIBCO EMS.

In any case, does the native ActiveMQ compression provide end-to-end compression between C#/Java clients? If not, how do we get C#/Java clients to exchange compressed messages?

There's not a direct way of doing this via the NMS API but there are
some tricks that can allow you to get the byte[] from a MapMessage if
you really wanted to. There is another option that might be better that
will be available in the NMS.AcitveMQ 1.2.0 release. You can now set a
property on the Connection instance to enable compression and provide a
CompressionPolicy instance that defines the compression method used to
compress and decompress the body of a Message. By default NMS.ActiveMQ
just uses the GZipStream built into .NET but if you want to actually
trade messages between Java and .NET then you'd need to use something
like the DotNetZip library which provides a ZlibStream class that can
compress and decompress in a format that's compatible with the Java
client's own compression format.

Regards
Tim.

My problem is that when the JVM dies, the consumer remains active (i can see

If i use TCP instead of HTTP, the dead consumers are inactivated correctly

Anyone been thru something like this or can suggest me a workaround?

Re: URI for Queue

Hi Dejan,
This is also NOT working.(getting 404 resource not found) I am NOT using a servlet as a client. It's a POJO as a client to MQ.

I am still trying to find the URI for the Queue!

Thanks,

Hi Uday,

it all depends how you configure your servlet. In the demo app, distributed
with the ActiveMQ, it is configured to listen to "messages/*" path, so the
full path to your queue would be

http://host:port/demo/messages/myqueue

Regarding security, you can secure it like any other web app. I suggest you
take a look at webapp/demo/WEB-INF/web.xml and appropriate articles on the
web on how to secure Java web apps.

Re: How do I do this: "configure AMQ to listen on the outbound network"

one thought, are you using the wildcard address in the transport connector
url: "tcp://0.0.0.0:61616" to listen on all interfaces?

This is why I asked about your use case. I wanted to distinguish the
use case from the code you were trying to write as the two are
distinctly separate items. I'm glad that Gary's suggestion worked out.

JMSException - Reason: java.net.ConnectException: Connection refused: connect

2009-11-25T07:37:32Z

Hi... I could use a little help.

My servicemix client works locally but not remotely.

Here's the code:
ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory(user, password, url);
Connection connection = connectionFactory.createConnection();

INFO XXXX - Caught: javax.jms.JMSException: Could not connect to broker URL: tcp://XX.XX.XX.XX:61616. Reason: java.net.ConnectException: Connection refused: connect

BTW, on the linux server machine, I did the following to open all ports and there is no router in the mix:
iptables -P OUTPUT ACCEPT
iptables -P INPUT ACCEPT
iptables -P FORWARD ACCEPT

Any help would be appreciated!

Thanks!

Re: How to "activate" an interceptor

2009-11-25T07:19:47Z

Now everything works!
Thank you Gary (and bsnyder too) !

This was the final configuration.

Client Side
----------
In java code I use ActiveMQConnectionFactory
(previously, I used "generic" JMS ConnectionFactory) in order
to call connectionFactory.setAlwaysSyncSend(true) method.

In jndi.properties file I specify in this way AMQ URL:
java.naming.provider.url = tcp://<my host>:61616?wireFormat.maxInactivityDuration=0&jms.useAsyncSend=false

ServerSide
----------
In AMQ 5.3 xml conf file:

<destinationPolicy>
<policyMap>
<policyEntries>
<policyEntry queue="NAM_QUEUE_01" producerFlowControl="true" advisoryWhenFull="true"
memoryLimit="20 kb">

<pendingQueuePolicy>
<vmQueueCursor/>
</pendingQueuePolicy>

</policyEntry>
</policyEntries>
</policyMap>
</destinationPolicy>

<systemUsage>
<systemUsage sendFailIfNoSpace="true">
<memoryUsage>
<memoryUsage limit="200 mb"/>
</memoryUsage>
<storeUsage>
<storeUsage limit="1 gb" name="foo"/>
</storeUsage>
<tempUsage>
<tempUsage limit="100 mb"/>
</tempUsage>
</systemUsage>

With setAlwaysSyncSend() method, client receives ResourceAllocationException.
With <vmQueueCursor/> policy, exception is raised in a deterministic way
(in my tests always after 20 messages).

There is no reason to test 5.4 SNAPSHOT (5.3. is already good).
I try to redo this test using 5.1 release.

Ciao,
Moreno

When the queue memory limit is reached and the system memory limit is *not*
reached (such that no spooling to disk occurs) (or if you use a
vmPendingMessageCursor (so messages are always in memory)) the send
operation will fail with a ResourceAllocaitonException which will be
propagated back to the client, which will be blocked because of the sync
send.
