FarmWarDeployer Tomcat 7.0.12 Clustering Help
I'm trying to use org.apache.catalina.ha.deploy.FarmWarDeployer with Tomcat 7.0.12 to deploy my war files to a Tomcat cluster (two Tomcat's both version 7.0.12.) They war file is successfully deployed to both Tomcats but then the war is immediately un-deployed from one of them. The following error is logged (ClusterTest is the application name.) SEVERE: Application [/ClusterTest] is being serviced. Touch war file [ClusterTest.war] again! -S - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Re: FarmWarDeployer Tomcat 7.0.12 Clustering Help
Sorry, I thought the question was obvious. It deploys but then undeploys with the severe error I mentioned below. I don't want the error I want the FarmWarDeployer to deploy the war to both Tomcats and remain deployed... C:/Tomcats/apache-tomcat-7.0.12_node1 C:/Tomcats/apache-tomcat-7.0.12_node2 This is from node1 server.xml.

Clustering help
Not having much luck getting a simple cluster to work. Using nginx as a front end/load balancer against two tomcat instances on the same machine (for now). SuSE Linux 11.1. I see this message in the startup log, making me think the tomcat instances are not talking: INFO: Manager [localhost#/Struts1]: skipping state transfer. No members active in cluster group. I have a simple test page in the web app that shows the session ID and the instance of tomcat that it is hitting (by server port number) and the session id changes whenever ngnix directs the request to a different instance. as far as I can tell, multicast is enabled on eth0: eth0 Link encap:Ethernet HWaddr 00:1D:09:C4:C2:9A inet addr:192.168.3.5 Bcast:192.168.3.255 Mask:255.255.255.0 inet6 addr: fe80::21d:9ff:fec4:c29a/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 I've added a route for the mulitcast address to eth0: Kernel IP routing table Destination Gateway Genmask Flags Metric RefUse Iface 228.0.0.4 0.0.0.0 255.255.255.255 UH0 00 eth0 192.168.3.0 0.0.0.0 255.255.255.0 U 1 00 eth0 127.0.0.0 0.0.0.0 255.0.0.0 U 0 00 lo 0.0.0.0 192.168.3.254 0.0.0.0 UG0 00 eth0 localhost is mapped to the eth0 interface: ping localhost PING mlcx300 (192.168.3.5) 56(84) bytes of data. 64 bytes from mlcx300 (192.168.3.5): icmp_seq=1 ttl=64 time=0.046 ms I've tried the simple config: Cluster className=org.apache.catalina.ha.tcp.SimpleTcpCluster/ as well as the detailed config below.
