How to limit queue depth by #msgs

Hi, Is there a way to limit the queue depth of an ActiveMQ queue in number of messages? I know there are ”per destination policies” that can detect queue usage in terms of memory used. However, the number of messages may indicate other things, like how many .log files (kahadb) that can be tied

Re: Consumer not able to consumer messages from queue

Thanks for the reply. I don't have the stack trace currently with me and I have not been able to reproduce this issue. In my broker I log hourly destination stats and for this particular topic I observed that the messages consumption doesn't stop immediately rather it happens overtime. [destName:

Re: Is JDBC still used?

Oh, and JDBC has been known to have issues - especially having poor performance. There is no optimization in its interactions with the DB at all (e.g. no indices). -- View this message in context: http://activemq.2283324.n4.nabble.com/Is-JDBC-still-used-tp4689546p4689628.html Sent from the Act

Re: Selector and Virtual Topic

That's close. Selectors can be terrible for performance. The way ActiveMQ applies selectors is like this: ON MESSAGE DISPATCH WHILE ( message is NOT dispatched ) AND ( more consumers exist ) IF selector matches THEN DISPATCH message END IF The problem for per

Re: Unable to configure Network of brokers successfully with AMQP

Unable to configure Network of brokers successfully with AMQP

Hi, I am trying to setup an active mq cluster as "network of brokers" and facing some issues in getting it to success if I use AMQP protocol ( between consumer, producer and brokers). And With TCP/Openwire it seems to be working fine. I am using 5.8.0 version of Active MQ. Looking for some valua

Re: Consumer not able to consumer messages from queue

I would look at a stack trace inside the application - try to find the consumer threads and see if they are active, and if-so, what they are doing. If all is normal, they should be waiting to receive a message from the ActiveMQ transport. Also, check the broker logs for messages. Anything relate

Consumer not able to consumer messages from queue

Hi, I have a session aware message listener inside a DMLC with 5 concurrent consumers consuming messages from a queue. This listener will send a message everytime it receives a messages using the same session object to another topic by creating a producer. This setup runs fine for around 15 days a
