Subject RE: Tomcat 5.5.7 - error trying to replicate session on Linux [SOLVED]
Date Wed, 23 Feb 2005 04:28:06 GMT
OK, I just had to re-read the comments in server.xml and think about my
setup a bit more. It still seems like it should have worked the other
way [shrug]. Basically I had to tell the cluster setup to use only the
network adapters that represent the private link between the two servers
(ignoring the other NIC that is my outlet to the Internet).

Anyway I changed server.xml as follows:
  1) Added mcastBindAddr to thee "<Membership" tag.
  2) Changed tcpListentAddress from "auto" to the actual NIC that I
wanted it to listen on.

Here's the "cluster" section of my server.xml in case anyone can benefit
from it:

        <Cluster
className="org.apache.catalina.cluster.tcp.SimpleTcpCluster"
                 managerClassName="org.apache.catalina.cluster.session.D
eltaManager"
                 expireSessionsOnShutdown="false"
                 useDirtyFlag="true"
                 notifyListenersOnReplication="true">

            <Membership
                className="org.apache.catalina.cluster.mcast.McastServic
e"
                mcastAddr="228.0.0.4"
                mcastPort="45564"
                mcastBindAddr="192.168.11.3"
                mcastFrequency="500"
                mcastDropTime="3000"/>

            <Receiver
                className="org.apache.catalina.cluster.tcp.ReplicationLi
stener"
                tcpListenAddress="192.168.11.3"
                tcpListenPort="4001"
                tcpSelectorTimeout="100"
                tcpThreadCount="6"/>

            <Sender
                className="org.apache.catalina.cluster.tcp.ReplicationTr
ansmitter"
                replicationMode="pooled"
                ackTimeout="15000"/>

            <Valve
className="org.apache.catalina.cluster.tcp.ReplicationValve"
                   filter=".*\.gif;.*\.js;.*\.jpg;.*\.png;.*\.htm;.*\.ht
ml;.*\.css;.*\.txt;"/>

            <Deployer
className="org.apache.catalina.cluster.deploy.FarmWarDeployer"
                      tempDir="/tmp/war-temp/"
                      deployDir="/home/ltojsw/jakarta-tomcat-5.5.7/webap
ps"
                      watchDir="/home/ltojsw/jakarta-tomcat-5.5.7-deploy
er/build/webapp"
                      watchEnabled="false"/>
        </Cluster>
