Hi,
I'm trying to do a POC using neo4j and spring-data-graph. I have configured 3
VMs running zookeeper and deployed a simple webapp to tomcat on each instance.
I've run into a bit of a problem with replication though. I can only see data
being replicated when I restart each tomcat instance – which is obviously no
good.
I have the following in my application context:
<bean id="graphDatabaseService"
class="org.neo4j.kernel.HighlyAvailableGraphDatabase" destroy-method="shutdown"
scope="singleton">
<constructor-arg index="0" value="${database.path}"/>
<constructor-arg index="1">
<map>
<entry key="ha.machine_id" value="${server.id}" />
<entry key="ha.server" value="zoo1:${ha.server.port}" />
<entry key="ha.zoo_keeper_servers" value="${zookeeper.servers}"
/>
<entry key="enable_remote_shell" value="port=1331" />
<entry key="pull_interval" value="1" />
</map>
</constructor-arg>
</bean>
I am starting "zoo1" first so that it becomes the master. Server.id is
allocated at runtime from a system property set on each machine –Dserver.id=x
in the tomcat startup script. From what I understand the pull_interval=1
setting means that data should be synchronized once per second, yet I am only
seeing it happen when the servers are bounced. Am I missing something?
Thanks,
Toby.
