Artemis: java.net.BindException: Cannot assign requested address - jms

Question

I am trying to create a cluster of Artemis Servers. I have two artemis servers with following settings in the broker.xml as discussed in this documentation.
A snippet of broker.xml is as follows
<acceptors>
<!-- Acceptor for every supported protocol -->
<acceptor name="artemis">tcp://0.0.0.0:61616?tcpSendBufferSize=1048576;tcpReceiveBufferSize=1048576;amqpMinLargeMessageSize=102400;protocols=CORE,AMQP,STOMP,HORNETQ,MQTT,OPENWIRE;useEpoll=true;amqpCredits=1000;amqpLowCredits=300;amqpDuplicateDetection=true</acceptor>
<!-- AMQP Acceptor. Listens on default AMQP port for AMQP traffic.-->
<acceptor name="amqp">tcp://0.0.0.0:5672?tcpSendBufferSize=1048576;tcpReceiveBufferSize=1048576;protocols=AMQP;useEpoll=true;amqpCredits=1000;amqpLowCredits=300;amqpMinLargeMessageSize=102400;amqpDuplicateDetection=true</acceptor>
<!-- STOMP Acceptor. -->
<acceptor name="stomp">tcp://0.0.0.0:61613?tcpSendBufferSize=1048576;tcpReceiveBufferSize=1048576;protocols=STOMP;useEpoll=true</acceptor>
<!-- HornetQ Compatibility Acceptor. Enables HornetQ Core and STOMP for legacy HornetQ clients. -->
<acceptor name="hornetq">tcp://0.0.0.0:5445?anycastPrefix=jms.queue.;multicastPrefix=jms.topic.;protocols=HORNETQ,STOMP;useEpoll=true</acceptor>
<!-- MQTT Acceptor -->
<acceptor name="mqtt">tcp://0.0.0.0:1883?tcpSendBufferSize=1048576;tcpReceiveBufferSize=1048576;protocols=MQTT;useEpoll=true</acceptor>
</acceptors>
I added following to the broker.xml
<connectors>
<connector name="nettyartemis">tcp://localhost:61619</connector>
</connectors>
<discovery-groups>
<discovery-group name="my-discovery-group">
<local-bind-address>172.16.9.3</local-bind-address>
<group-address>231.7.7.7</group-address>
<group-port>9876</group-port>
<refresh-timeout>10000</refresh-timeout>
</discovery-group>
</discovery-groups>
<broadcast-groups>
<broadcast-group name="my-broadcast-group">
<local-bind-address>172.16.9.3</local-bind-address>
<local-bind-port>5432</local-bind-port>
<group-address>231.7.7.7</group-address>
<group-port>9876</group-port>
<broadcast-period>2000</broadcast-period>
<connector-ref>nettyartemis</connector-ref>
</broadcast-group>
</broadcast-groups>
In local-bind-address of discovery-groups I tried using 172.16.19.3, 172.16.19.7 and 172.16.19.8. Now, when I run one server it gives me following WARNING which (I think) means that the broadcast is not started resulting in no cluster.

Any suggestion why this is happening? I couldn't find any online resources explaining this on internet.

Answer 1

It might help someone else, I found my mistake just after posting this question
local-bind-address. This is the local bind address that the datagram
socket is bound to. If you have multiple network interfaces on your
server, you would specify which one you wish to use for broadcasts by
setting this property. If this property is not specified then the
socket will be bound to the wildcard address, an IP address chosen by
the kernel. This is a UDP specific attribute.
So this is ip address of the system where artemis server is running.
