I am trying to get clustering working with Tomcat 5 and am finding a few problems.
I have uncommented the cluster section and the recommended valve to filter requests
for static content, so the cluster section in the host
section of server.xml looks like this:
<Cluster className="org.apache.catalina.cluster.tcp.SimpleTcpCluster"
name="TestCluster"
debug="10"
serviceclass="org.apache.catalina.cluster.mcast.McastService"
mcastAddr="228.0.0.4"
mcastPort="45564"
mcastFrequency="500"
mcastDropTime="3000"
tcpThreadCount="2"
tcpListenAddress="auto"
tcpListenPort="4001"
tcpSelectorTimeout="100"
printToScreen="false"
expireSessionsOnShutdown="false"
useDirtyFlag="true"
replicationMode="synchronous"
/>
And I have changed the listen port in the second member to be 4002. On start-up, the
following INFOs appear in catalina.out:
[InMemoryReplicationManager] Starting clustering manager...:/reptest
[InMemoryReplicationManager] Starting... no cluster associated with this
context:/reptest
I am testing using the SessionExample servlet that ships with tomcat. Both members
join the cluster and data is replicated. However, when
data is received, the following WARNING is logged in the receiving cluster member and
the session is not replicated properly:
org.apache.catalina.cluster.tcp.SimpleTcpCluster messageDataReceived
WARNING: Context manager doesn't exist:/reptest
Any ideas on how to solve this?
Regards,
Cendil
