Share libraries for Context Descriptors

Hi, I have a cluster with three tomcat6's instances. My tomcats access applications on a common repository server, so I use Context descriptors in order to point the applications. Differents apps often use same libraries, and I'd like to share libraries at Context Descriptor level (in context.xml).

Nagios3 and Tomcat6 configuration under Apache2.2

Hi, I have a Tomcat6 cluster under Apache2.2. I'd like to monitor the system and so I want to use nagios3 but I don't know how configure VirtualHosts for Tomcat and Nagios under Apache ( I use Ubuntu so I have /etc/apache2/ports.conf and /etc/apache2/sites-enabled/000-default). I hope you can help

cluster deployment by context descriptors

Hi all, I have a cluster with Apache2.2 and three Tomcat 6 instances in load balance and sticky sessions on three different servers. I use another server like webapps repository, so my tomcat's go to applications by context descriptors. But I don't want all three tom go on all apllications, so I re

Re: cluster deployment by context descriptors

So I must configure vhost under apache for a specific webapp and then create context descriptor for specific tomcats under default host (ex. under tom1 and tom2 and not under tom3). Or must I create vhost under specific tomcats too? 2009/11/20 Pid > On 20/11/2009 09:22, Paolo Santarsiero wr

Manage log files in a cluster

Hi, I have a cluster with many tomcat and I want to manage the log's files on a centralized basis in order to collect, display, analyze and manage all files of logs from a single client. Do you know a system that allows me to do? Many thanks.

Re: Max heap size

Well, it depends on the jvm memory usage. I use for my system this JAVA_HOME jvm parameters in catalina.sh: -Xms64m -Xmx512m -XX:MaxPermSize=200m It is not certain that this configuration is good for your system. I set 200Mb for max permgen size because the objects in permgen on average occupy 120

Re: Tomcat dies suddenly (was JVM goes away)

In order to monitor java memory at chrash time you can add to JAVA_OPTS these directives -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/your/tomcat/folder/memorydump.hprof In this way, if tomcat goes in out of memory, you have an image of memory (memorydump.hprof) that you can analyze by an ex

worker redirect problems

Hi, in my cluster I have many tomcat enable and two tomcat in sleeping, all in load balancing. The "sleepers" start only when one or more active tomcat go down, managing thier sessions. In order to do this I use worker.tomcatActive.redirect=tomcatSleeper for active tomcat and worker.tomcatSleeper.

I think the only possibility in order to fix RMI server port behind a firewalled system is to use JMX Remote Lifecycle Listener in server.xml and add catalina-jmx-remote.jar in lib folder. I used it for remote jvm monitoring and now works fine. You can read procedure here http://tomcat.apache.org

Hi, I think the best way is to share a central repository (local or net mounted) for webapps and create for each one and for each tomcat the right context with the right path. regards On 26 August 2010 16:03, André Warnier wrote: > Luca Gervasi wrote: > >> On Wed, 2010-08-25 at 10:50 -0300, Fern
