RE: Tomcat 5.5.7 - error trying to replicate session on Linux
BTW, Each of my two servers has two network cards: a) One facing the internet; b) the second is a private connection between the two servers. The second connection is intended for session replication. Also, I did not specify an mcastBindAddr - though it probably should be specified as the second network card.

RE: Tomcat 5.5.7 - error trying to replicate session on Linux [SOLVED]
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 --- Richard Richard Mixon (qwest) wrote: OK, we still have one more issue with our Tomcat cluster as we move to our Linux environment.
