you probably didn't uncomment the ReplicationValve in server.xml
I will remove this as many people make this mistake, and the valve will be
automatically added when the cluster starts

Subject: Tomcat5 Clustering problem .
Hello,
I followed the Tomcat5 clustering document in jakarta site. But it seems not
work.
The following is the configuration in server.xml :
Tomcat1:
<Cluster className="org.apache.catalina.cluster.tcp.SimpleTcpCluster"
name="FilipsCluster1"
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"
/>
Tomcat2:
<Cluster className="org.apache.catalina.cluster.tcp.SimpleTcpCluster"
name="FilipsCluster2"
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="4002"
tcpSelectorTimeout="100"
printToScreen="false"
expireSessionsOnShutdown="false"
useDirtyFlag="true"
replicationMode="synchronous"
/>
As I run two Tomcat5 instances in one machine, I changed the tcpListenPort
(4001, 4002). And the name is also different.
I used Apache JK as the Load Balance. The Load Balance is no problem, when
the Tomcat1 is crashed, it can switch to the Tomcat2, but failed to hold the
session ?????
Anything I missed or how can solve it if I want to make Tomcat clustering
????
Platform:
==========================
JDK1.4.2
Win98
Tomcat5.0.9
==========================
Please help.
Best regards,
Eric
