[jira] [Updated] (ARTEMIS-2589) Automatic Client failover is not
working
[ https://issues.apache.org/jira/browse/ARTEMIS-2589?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Justin Bertram updated ARTEMIS-2589:
------------------------------------
Affects Version/s: (was: 2.6.4)
> Automatic Client failover is not working
> ----------------------------------------
>
> Key: ARTEMIS-2589
> URL: https://issues.apache.org/jira/browse/ARTEMIS-2589
> Project: ActiveMQ Artemis
> Issue Type: Bug
> Affects Versions: 2.10.0
> Reporter: richard krasowski
> Assignee: Clebert Suconic
> Priority: Major
>
> +*Problem*+:
> Automatic Client failover (reconnection due to server shutdown) is not working properly.
>
> *+Description+*:
> I created a live/backup group over server-discovery mechanisms. They both broadcast their connectors over udp and a multicast address. When the both servers (live and backup) are started, they are successfully recognized as live and backup.
>
> I have 2 clients both implemented in Java Spring. One client acts as the producer and one client acts as consumer. They are configured over a ActiveMQJMSConnectionFactory and over DiscoveryGroup mechanisms (udp://{color:#008000}231.7.7.7:{color}{color:#0000ff}9876){color}. The producer has a jmsTemplate and the consumer is realized as a Message driven bean.
> When I send 20 messages over the producer the live server acknowledges them and forwards them to the consumer. When I shutdown the live-server the consumer successfully failover to the backup server but the producer says: "*Backup is not active, trying original connection configuration now.*"
> And after a minute it throws an Error "*org.apache.activemq.artemis.core.client : AMQ214016: Failed to create netty connection*" with an *java.net.UnknownHostException*:
> It seems like the client receives the live/backup configuration and tries to reconnect to live server but after that it does not successfully failover to backup server.
>
> I created a github repo with a docker-compose environment. There is a producer, a live/backup artemis broker pair and a consumer.
> https://github.com/krasowskir/messaging_poc_infrastructure
>
> My goal is to send 200 messages and during the sending process I want to shutdown the server (activemq0) and I want to see a successful client failover of the producer to backup server (activemq1)
