Hello everyone, As was recently mentioned [1], we started to analyze the currently used queue system. During the first iteration, we started to test reliability.
Testing environment: AWS Hardware: | Producer | m5.large | 2vCPU / 8GiB | | Consumer | t3.medium | 2vCPU / 2GiB | Software: OS: CentOS Linux release 7.5.1804 Java: Oracle JDK SE 8 Update 191 ActiveMQ: ActiveMQ 5.15.6 Artemis: ActiveMQ Artemis 2.6.3 Client: JmsTools [2] Configuration: ActiveMQ stand-alone: 1. activemq.xml: added 'individualDeadLetterStrategy' 2. ACTIVEMQ_OPTS=-Xms512M -Xmx7G 3. Started as systemd service Artemis stand-alone: 1. artemis.profile: modified JAVA_ARGS to -Xms512M -Xmx7G 2. jolokia-access.xml: modified to <allow-origin>*</allow-origin> 3. Started as systemd service Methodology: 1. Run producer for 5 minutes on the queue. 2. Run consumer to consume all messages from the same queue. 3. Iterate 5 times. 4. Restart activemq or artemis service during producer/consumer work, depending on the test. Client: Producer: java -Xms512m -Xmx3G -jar AmqJmsProducer-1.8-jar-with-dependencies.jar -url failover:\(tcp://10.0.20.28:61616,tcp://10.0.20.28:61616\) \ -notran \ -log Logs \ -t 10 \ -duration 5 \ -id \ -type TEXT \ -queue Test Consumer: java -Xms512m -Xmx3G -jar AmqJmsConsumer-1.8-jar-with-dependencies.jar \ -url failover:\(tcp://10.0.20.28:61616,tcp://10.0.20.28:61616\) \ -log Logs \ -timeout 60000 \ -t 10 \ -verify \ -drain \ -queue Test Restarts: service=activemq #service=artemis while :; do interval=30 sudo systemctl restart $service sudo systemctl status $service | grep "Active:.*;" sleep $interval done > Note: Artemis service was restarted every 120 seconds and sometimes > restarts were stopped because of Artemis long start because of journal > checking.

Is there any configuration from the default ones which may permit us to achieve zero messages loss with ActiveMQ an Artemis? 2. If we assume that used tools may have issues/bugs, which one may we use for such type of tests? 3. Any advices. Thank you! Slava.
