<div>Hi,<br>
<br>
once you start both nodes, do you have the message in the
server.log as mentioned in the troubleshooting section:
<a href="http://docs.jboss.org/keycloak/docs/1.2.0.CR1/userguide/html/clustering.html#d4e2750" target="_blank">http://docs.jboss.org/keycloak/docs/1.2.0.CR1/userguide/html/clustering.html#d4e2750</a>
?<br>
<br>
Also I recall that for TCPPING you need to manually mention all
the cluster nodes in the JGroups configuration of TCPPING
protocol. This needs to be done on both nodes AFAIR. Do you have
it configured?<br>

<div>Hi,<br>
<br>
</div>
We're trying to have a clustered environment with two
servers, and need Infinispan caches to work perfectly. <br>
<br>
We're using AWS servers for all our requirements, and
they don't support multicasting. Hence the UDP option is
out for us. So, as per the JIRA ticket KEYCLOAK-979, we
have tried to continue with TCP instead. However we've
had no success. Changes don't get synced between the
servers.<br>
<br>
</div>
To configure TCPPING, we've referred both KEYCLOAK-979
ticket contents and <a href="http://middlewaremagic.com/jboss/?p=2015" target="_blank">http://middlewaremagic.com/jboss/?p=2015</a>.
We have enabled TCP communication in our VPC and have all
the necessary ports open in our servers. <br>
<br>
We've followed the step given at <a href="http://docs.jboss.org/keycloak/docs/1.2.0.Beta1/userguide/html/clustering.html" target="_blank">http://docs.jboss.org/keycloak/docs/1.2.0.Beta1/userguide/html/clustering.html</a>
to setup Infinispan and related configs. <br>
<br>
</div>
What could we be doing wrong here? Any configuration we're
missing?<br>
<br>
<br>
</div>
Thanks,<br>

Lohitha.<br>
