Re: Best practices for deployment on cluster environment

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 a...@ice-sa.com wrote: Luca Gervasi wrote: On Wed, 2010-08-25 at 10:50

Tomcat clustering: LVS or AJP ?

I created an infrastructure with two balanced servers for Apache Web Server, and four servers at a lower level for Tomcat. The Tomcat are coupled to web server via mod_jk and they use the Tomcat's hearthbeat clustering system. Now my suggestion is to include all services (Apache HTTP, Tomcat, etc.

Re: Avoiding random JMX port on tomcat

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

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

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
