Re: How to enable file based persistence ?

Hi, looking at the available releases (Apache & FUSE) I see that the FUSE release does not contain the plugin. Therefore you can't use the FUSE release. However using the Apache ActiveMQ release http://www.apache.org/dyn/closer.cgi?path=%2Factivemq%2Fapache-activemq%2F5.3.2%2Fapache-activemq-5.

Re: Log4J ActiveMQ JMS Appender

Hi Gary, thanks for the quick reply. In fact, my Broker was mis-configured. I started a Broker with the default config and it connects perfectly. You actually don't need to restrict the log level of activemq. You can leave it do DEBUG (and of course not using JMS appender). But you need to have

Re: What does the topic size attribute actually mean ?

The 'size' in the statistics you see is the total number of messages which have been sent to this topic. Unsurprisingly, for topics it is the same as enqueueCount. I can only image these numbers to differ when you have a queue instead of topic. Then, the size represents the number of message in t

Re: Usage Manager memory limit reached for topic. Producer hangs

Hi Danilo, just as a remark (which has not really to do with your problem) : you may want to set memoryUsage to a lower value, since I think this is the size AMQ will use to keep messages in memory. If you set your JVM size to the same, you may not have space left for other objects (connection/to

Re: How can I remove a message from Queue

Hi abakar, This example below will read all message from a queue (until it is empty). Make sure that no producer runs. If you need to delete all messages you can also use jconsole (http://activemq.apache.org/jmx.html) to empty the queue (operation "purge"). Felix import javax.jms.Connection;

Hi Arjen, did you try to enable failover transport mechanism : http://activemq.apache.org/failover-transport-reference.html This will enable the client to reconnect in case of disconnection. the default transport url you use will NOT automatically reconnect. Cheers, Felix Arjen van der Meijde

Prefetch documentation mismatch

Re: Expired message - does it work?

Hi Dan, If you play with message expiration make sure that your consumer/broker/producer have the same time since the TimeTtoLive of the message is set relative to your producer. If you broker is in the future relative to your producer and the gap is greater than your TTL you won't see any messag

Hi, I was wondering that one or the other might find the attached plugin useful. It allows to enforce the persistence mode for incoming messages. This case comes handy, whenever the connecting clients are not respecting (or forgetting) message policies. In our case, one client connected and s

Hi, seems like its still a problem in 5.2.0 (fuse 5.2.0.2). The problem is quite easy to reproduce: 1.Limit the memoryUsage in activemq.xml to -say- 50MB. 2.set producer flow control=false and disable saving messages to disk. 2.Start one producer publishing non-persistent messages with TTL=5sec
