broker cluster node failure recovery

2014-10-30 Thread jonb
I have a network of several brokers where a couple nodes are producers to one queue and a couple of nodes are consumers on this same queue. We are testing high availability and in doing so pull the network cable on one of the consumers. While this is happening there is a steady message rate on th

Re: Potential Bug in Master-Slave with Replicated LevelDB Store

2014-10-30 Thread Tim Bain
I spent time last week trying to tune the parallel GC to prevent any objects from reaching OldGen once the broker was up and running in a steady state, to try to avoid expensive full GCs. My goal was zero full GCs for a broker with 3-6 months of uptime, to prevent clients and other brokers from fa

2014-10-30 Thread Tim Bain
Per the documentation in the link from my first email, you'll see that message when a destination is removed because it has been inactive (empty) for the inactiveTimeoutBeforeGC period. So if you're getting that message, it means that your destination has been empty for 60 seconds. This is entire

Not much else. Once the master is elected, the slave stores connect to elected master store and start receiving journal updates and synchronize their data files with the master. On Thu, Oct 30, 2014 at 5:20 AM, khandelwalanuj wrote: > Hi, > > I have gone through > http://activemq.apache.org/repl

ActiveMQ 5 update timeplan?

Hi, Can I ask what is the current timeplan for ActiveMQ 5? Will there be continued updates to version 5 or has development switched to version 6? Regards, David -- View this message in context: http://activemq.2283324.n4.nabble.com/ActiveMQ-5-update-timeplan-tp4686812.html Sent from the Acti

Tim, Thanks for that, but I'm trying to get rid of the messages by fixing the issue of the messages going outstanding, not changing the logging levels or turning off the feature. :) Anyone have a troubleshooting path or tuning recommendation, by chance? Tim Bain wrote: Well, you could get r

Well, you could get rid of those messages by choosing not to delete inactive destinations (documentation: http://activemq.apache.org/delete-inactive-destinations.html). Or you could tune Log4J to only show WARN level messages for that Logger On Thu, Oct 30, 2014 at 10:01 AM, Lodgen, Brad wro

What you're suggesting sounds like it would behave the same as if I use the static: transport with two nested URIs, except that I'd have more configuration boilerplate since I'd have an additional networkConnector on which I'd have to set all of my config options. Do I get something from using the

ActiveMQ "inactive for longer than X ms - removing ..."

I'm still learning tunables in activemq. Right now, I'm trying to tune and troubleshoot my environment to get rid of the numerous activemq.log entries showing "Inactive for longer than X ms - removing ...". I currently have the timeout set to 6ms, but the messages I'm sending normally respon

you may be able to achieve what you want with two network connectors. one to the primary and one to the backup. When both are alive and you use decreaseNetworkConsumerPriority and priority dispatch, messages should take the shortest path (priority decreases with number of hops). On 24 October 2014

Messages consumed multiple times without rollback?

Hi all, we encounter the following somewhat strange behaviour with ActiveMQ 5.8.0. I had no luck finding anything similar on the net about it though. We run an embedded broker with multiple queues. Non-persistent messages are put into Queue 1 by the clients. Consumers pull them from there (prefet

Zookeeper for replicated LevelDB

Hi, I have gone through http://activemq.apache.org/replicated-leveldb-store.html. What does zookeeper do other than election of master from ActiveMQ brokers ? Who takes care of replicating data from master broker to other slaves ? Thanks, Anuj -- View this message in context: http://activ
