Re: ActiveMQ Usage

ActiveMQ is being for real time, high volume data at a number of organizations. However, like all things it really depends on your use case. There are many tuning options for ActiveMQ - it would be best to ask here for guidance - but we'll need some more information - like volume, number of

Re: duplicates on master/slave broker failover

Evaluating this further it appears the broker is not persisting any information back to the database when it dispatches messages to consumers. I verified by removing update privs on the ACTIVEMQ_MSGS table as well as insert, update, and delete privs on the ACTIVEMQ_ACKS table. Yes we are using J

Re: Async error occurred -> ActiveMQ 5.2 and NMS

I found something interesting. If I remove delete privs on the ACTIVEMQ_MSGS TABLE (we're doing JDBC Master/Slave) there are a couple things happening... #1) I receive Async errors to the looks of it the same as before. #2) The same messages are getting delivered to the listener after a restart

ActiveMQ Usage

As mentioned in Use Cases of ActiveMQ, its being used in real-time, high-performance applications like trading, market-data distribution. Since ActiveMQ has been implemented in Java, I wonder that purpose is solved really? Wouldn't it be more faster if implemented in C/C++? IMO these high performa

duplicates on master/slave broker failover

Hello. We are running JDBC Master/Slave with ActiveMQ 5.2 and upon failing a master broker to slave broker we are seeing duplicate messages come through to the consumers processing a queue. These messages are not flagged as redelivered. It's my understanding that the consumer is suppose to go t

Re: ActiveMQ Failover exception

No, not seeing multiple messages. However, what I noticed just now i that it seems to be after some period of inactivity. And maybe that's just because part of the call stack contains a class called "InactivityMonitor." at org.apache.activemq.broker.region.PrefetchSubscription.assertAckMa

Re: ActiveMQ Failover exception

We're seeing on both 5.2 and 5.3. I have to check to see if we're getting duplicate messages. I don't think so but I have to check the logs when I get in. rajdavies wrote: > > Which version of ActiveMQ ? > On 25 Sep 2009, at 01:50, penguinone wrote: > >> >> >> We set up our active MQ to fai

Re: Getting negative number of pending messages

Hey thanks for your reply- :-) Yes I provided a test case a few days ago. I worked pretty hard getting this test case for you guys. I attached all the files to this thread after Timothy Bish asked for it in this thread. See a few replies earlier starting with "I'm attaching a sample app, conf

issues with connection start timeout

I have read the docs on the failover and the tcp transport. I understand I can set various properties on the broker URL. What I'm trying to do is build a very simple monitor that runs periodically to check that ActiveMQ is still alive and if not, send a notification that someone needs to start (

Hi Ivan, have you tried 5.3 snapshots? There were some similar issues that could be fixed. Cheers -- Dejan Bosanac Open Source Integration - http://fusesource.com/ ActiveMQ in Action - http://www.manning.com/snyder/ Blog - http://www.nighttale.net On Fri, Sep 25, 2009 at 10:31 AM, Ivan Pryvalo

Openwire topic-consumer disconnects after some time

Hi List, I have some topics with very few messages (it can be days or weeks before a message arrives) on it. The consumers to those topics disconnect after some time and don't reconnect afterwards. I have no idea where to put the blame (activemq-server, activemq-consumer, spring?), but I'd lik
