Hi All,
We have configured Artemis 2.31.0 symmetric cluster in the test environment.
Example of cluster configuration on one of the nodes:
<cluster-connections>
<cluster-connection name="test">
<address></address>
<connector-ref>amq1-connector</connector-ref>
<check-period>1000</check-period>
<connection-ttl>5000</connection-ttl>
<min-large-message-size>50000</min-large-message-size>
<call-timeout>5000</call-timeout>
<retry-interval>500</retry-interval>
<retry-interval-multiplier>1.0</retry-interval-multiplier>
<max-retry-interval>5000</max-retry-interval>
<initial-connect-attempts>-1</initial-connect-attempts>
<reconnect-attempts>-1</reconnect-attempts>
<use-duplicate-detection>true</use-duplicate-detection>
<message-load-balancing>ON_DEMAND</message-load-balancing>
<max-hops>1</max-hops>
<static-connectors>
<connector-ref>amq2-connector</connector-ref>
</static-connectors>
</cluster-connection>
</cluster-connections>
It works as expected. Then we add scaledown settings:
<ha-policy>
<live-only>
<scale-down>
<enabled>true</enabled>
<connectors>
<connector-ref>amq2-connector</connector-ref>
</connectors>
</scale-down>
</live-only>
</ha-policy>
It also works. When stopping first server, the messages are transferred to the
second server.
Adding graceful-shutdown:
<graceful-shutdown-enabled>true</graceful-shutdown-enabled>
<graceful-shutdown-timeout>300000</graceful-shutdown-timeout>
The graceful-shutdown works: broker waits for the clients to disconnect before
shutdown. But scale-down does not work: the messages are not sent to the second
server.
Is it possible to use both settings?
