Re: Artemis JMX not showing queues

To be clear, calling org.apache.activemq.artemis.api.jms.ActiveMQJMSClient#createQueue simply creates a a client-side representation of a JMS Queue (as the JavaDoc indicates). Nothing happens on the server when that method is invoked. I opened https://issues.apache.org/jira/browse/ARTEMIS-510

Artemis JMX not showing queues

Hi, I am trying out artemis and creating different JMS queues from client programatically. Code itself works, but when I log into JMX, I see that few queues are listed under "Core/Queue" with jms.queue.# prefix, but they don't appear under "JMS/Queue". I don't understand how this could happen.

Re: Testing Master Slave on Shared File System

I’ve done quite a bit of master/slave setups - they’ve never been an issue as long as I had a filesystem that supported locking. I’ve used NFSv4 and GFSv2 for these setups. If I’m reading this correctly, you’ve setup a volume on a SAN and mounted it on both systems as an ext4 filesystem. If t

Re: Testing Master Slave on Shared File System

Are both volumes mounted with ext4? Does EXT4 have support for distributed lock sharing? Sounds like one server would mount rw and the other would be mounted ro and there aren't any shared locks. I'm not as current on the latest EXT4 features, but do know a cluster-aware filesystem such as GF

Sure, YOU know it was a clean shutdown, but how does your slave broker know which type it was? Methods to signal that fact could be added, but none currently exists in the code. On Apr 29, 2016 7:14 AM, "Christian Schneider" wrote: > I do not assume that the restart will be clean when the master

I do not assume that the restart will be clean when the master dies. In our case the brokers are shutdown orderly during a regular maintenance where some of the customer software is updated on the system. So in the case were we experienced the slow start it was a clean shutdown. Christian On

Using mKahaDB with a separate KahaDB instance for the DLQ is the best idea I know of for dealing with the problem you describe. A JIRA enhancement request exists for compacting KahaDB journals ( https://issues.apache.org/jira/plugins/servlet/mobile#issue/AMQ-3978). You should vote for it, and if

Also, your question makes the assumption that files your broker stumbles upon when it becomes master were written by a previous master that shutdown cleanly, which is a rather optimistic assumption to make. On Apr 29, 2016 7:01 AM, "Tim Bain" wrote: > By reading the code ( > http://www.grepcode.c

Separate kahadb for queues and dead letter queues?

We have the issue that our journals at a customer are very large. We analyzed the messages in the system and found that most of the time the normal queues stay at a very low number of messages near to 0. The only queues that hold messages for longer periods of time are the dead letter queues.

Re: Failover very slow with kahadb while restart of master is fast

We have found the main cause for this issue. Current Master and new Master seem to do the exact same things on startup. They read all the journals. It seems that the OS is caching the files in memory in some cases. The master seems to have all the jorunal files in the cache. So when it restarts
