clustering tomcat 5.0.19 issues
Hi All, I have done clustering of tomcat. I have two different machines running tomcat which join the cluster. I am testing my application . But in between I see some errors like 1) context manager doesn't exist. 2)Unable to send replicated message, is server down? 3) SEVERE: TCP Worker thread in cluster caught 'java.io.IOException: An established connection was aborted by the software in your host machine' closing channel It would be grateful if somebody can tell what are these errors for . And also I have another query. I have my apache as the load balancer. Currently the requests are dispatched to each tomcat by the apache. I want this dispatch to happen in a specific way like one tomcat getting 2 requests and other getting just one request. Like a ratio of 2:1 . How can I do it ? Thanks in advance shyam - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: clustering tomcat 5.0.19 issues
1) context manager doesn't exist. yep, I am only printing this because of debug. All this means is that you are a member of the cluster but the server has not fully started up yet. hence you are receiving messages for a non existent context. 2)Unable to send replicated message, is server down? One of your nodes is not responding to messages, either you have some IP misconfiguration or something else is blocking the messages. I will add more info to that message to be able to track the problem down 3) SEVERE: TCP Worker thread in cluster caught 'java.io.IOException: While reading a message from another node, that node disappeared, got disconnected. This is also fine and should not affect your system any other questions, just let me know. someone else can answer your mod_jk load balancing questions.

Clustering tomcat 4
Hi all, I'm new to this list, and, of course, I have a question. I try to make a LinuxVirtualServer with several tomcat instances. So, I have servers with tomcat, Jvm, etc, installed (formerly JAVA_HOME and CATALINA_HOME) and I find the CATALINA_BASE directories on a file server. That is, conf, webapps, temp, work and logs are shared between servers... I think you begin to understand my problem. I found in the mailing list archive a good way to manage connectors (using entities). It works well. Now, I have a problem with the loggers. I really don't want to manage all the loggers of all the hosts by myself. So I need to put dynamic attributes in Loggers definitions, so that I can have the server name (node name) in the log file name. Ideally, I would like to dynamically adjust prefix or suffix attributes of the Logger definition. Has anyone found a way to do it ? Thank you for any help.

Re: Clustering Tomcat - Loadbalancing and Failover
mcastAddr=228.1.2.3 used for membership, tcpListenAddress and tcpListenPort indicate TCP for transporting the actual session. What is in place for security? Ideally you would only replicate data behind your own firewall, if you replicate data in a public zone, you are on your own. So the answer is, there is no security, never saw a need for it.

Clustering Tomcat with OSCAR
I was our intention is to cluster our apache/tomcat application server with a high performance clustering package called OSCAR. However, we saw a message in the OSCAR mailinglist archive stating that ..tomcat was not cluster aware in any sense. It mentioned using something called mod_backhand in Apache. Is anyone using tomcat application servers in a clustered environment? Thanks. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Clustering Tomcat with OSCAR
Tomcat 5 ships with a cluster module, that I have back ported to 4.1.x, you have to use JDK1.4 since it uses java.nio for performance reasons http://www.filip.net/tomcat-clustering.html Filip -Original Message- From: Matthew Sachs [mailto:[EMAIL PROTECTED] Behalf Of Frank Dmuchowski Sent: Thursday, March 20, 2003 10:40 AM To: [EMAIL PROTECTED] Subject: Clustering Tomcat with OSCAR I was our intention is to cluster our apache/tomcat application server with a high performance clustering package called OSCAR.

Hi ! have you ever tried google??# http://www.google.com/search?q=tomcat+cluster+session+replication I'm using the java-groups solution described in http://www.theserverside.com/resources/article.jsp?l=Tomcat and it works fine for me. We are running 6 tomcats4.1 on jdk1.4.1/linux 7.3 on dual-Xeon2,8Ghz Hardware, and it works great. Christoph [EMAIL PROTECTED] P.S.: But I changed the source a bit.

Clustering Tomcat
Hi, Has anyone had any experience of clustering Tomcat that they would like to share? I have read that it is possible to cluster Tomcat with Apache but I am not sure if it is possible to cluster Tomcat on its own. Any help/pointers would be appreciated. Regards Jim.
