RE: Using topics for publishing broker metrics

Your assumption is valid, and having both the master and the slave (times N pairs) in the failover URI guarantees that you'll be able to reach a broker no matter who's active. On Dec 17, 2015 7:28 AM, "Basmajian, Raffi" wrote: > Hi Tim, > > We assumed if the broker was a slave it would be unable

Re: ActiveMQ failover Java-level deadlock

Make sure you submit a bug in JIRA. Mailing list posts may get ignored and then forgotten without a fix, especially since most recent LevelDB questions get no response. Submitting a bug ensures it doesn't get forgotten. Tim On Dec 17, 2015 2:23 PM, "stephenschaeffer" wrote: > As an addendum, t

As an addendum, that deadlock occurred only on the 03 node, and once that one node was bounced, traffic is able to flow again. -- View this message in context: http://activemq.2283324.n4.nabble.com/ActiveMQ-failover-Java-level-deadlock-tp4705128p4705134.html Sent from the ActiveMQ - User mailin

ActiveMQ failover Java-level deadlock

Hi all, We have an environment as follows: ActiveMQ 5.12.0 on 3 nodes using Zookeeper Zookeeper 3.4.6 on the same 3 nodes. Java 1.8 RHEL Server 7.1 We can start up and verify that ActiveMQ failover is working by sending and consuming messages from different machines while taking ActiveMQ

Hi Tim, For problem #1: there are a lot of unconsumed messages, but each message havs an expiration time (max 2-3 weeks). Over the time the size of the KahaDB folder should be nearly constant. -- View this message in context: http://activemq.2283324.n4.nabble.com/Need-help-with-a-message-broke

RE: Using topics for publishing broker metrics

Hi Tim, We assumed if the broker was a slave it would be unable to publish to itself. But you're saying each broker should publish to "failover:(all brokers in cluster)" instead of "tcp://localhost:61616"? -Original Message- From: tbai...@gmail.com [mailto:tbai...@gmail.com] On Behalf

Re: Correctly configuring a network of brokers

A queue message exists on only one broker at a time, no matter what. If there is a consumer on broker 2 and A hasn't been excluded, or if your broker 1's networkConnector is configured to statically route A to broker 2, the message will be forwarded. Otherwise, the message will sit on broker 1 ti

Are all messages being immediately consumed, or is there a backlog of messages for a given message group when you close the message group? I would expect the message group to be closed immediately when the message with NMSXGroupSeg=-1 is sent (not when it is consumed), so if there is a backlog I w

Re: Using topics for publishing broker metrics

I wouldn't try to make your own advisory topics; just use normal topics as you've proposed. Wouldn't it be simpler to publish to a failover URL containing all the brokers rather than starting an embedded broker whose sole purpose is to publish stats? It seems like your proposed approach adds unne

Re: Need help with a message broker configuration

For problem #1, do you have any old but unconsumed messages? KahaDB can't compact its journal files, so a single old message that can't be deleted can cause KahaDB to keep a large number of files. For problem #2, why is that a problem? You haven't said anything that indicates that those advisory

Correctly configuring a network of brokers

If I have a NoB (total 2), and queue A is defined on one, it shows up on both as I would expect. If a Producer puts a messages to queue A on one of the brokers, does the message get forwarded over the bridge to 'both queue instances', or does it simply reside on the broker it was put on? I am a

Hey Dejan, I saw, that in the Windows distribution of ActiveMQ isn't any file like you described. I think you meant to look in the LINUX distribution. There is a file "bin/env" like you said. Do you have any experience on Windows distribution of ActiveMQ? I saw that there is a similar file calle

Hi Lectrismo, take a look at "bin/env” file in your ActiveMQ distribution. There you can set system properties. Please let us know how it works. I started working on an example for this, but never finished it. I hope to get back to that soon. Regards -- Dejan Bosanac about.me/dejanb On Thu, Dec
