Tomcat heap vs. java.exe
I have a quick question. When I run Tomcat 5.0.18, my java.exe starts with ~65MB. Then as my websites get hits, java.exe starts increasing. I run tomcat with the -Xms128m -Xmx256m options. So the startup heap size of tomcat is 128MB. After my first start, I usually have around 80 MB free memory for Tomcat. My question is, why is the startup java.exe size is smaller than my total heap size? Does the size of java.exe grow as the heap starts being used. I would expect java.exe to be at least 128 MB (plus the JVM memory) since that is how much is allocated.

Re: Tomcat heap vs. java.exe
My main concern is to make sure that there is no memory leakage of any sort. Our server has 1GB of ram. I'm running tomcat with -Xms128m -Xmx256m. In this case, I'm guessing that java.exe will eventually become 256MB + JVM memory ~= 370MB and stay stabilized like that. I don't want our server to use the page file very much as it slows down the performance very much. Do you think it makes sense to assume that java.exe won't exceed 370 MB (400 MB top) under these conditions? I'll go ahead and search the archives right away. Thank you for your time.

What I usually do is this:

Every web-app is in a context. Every context is in a path on the

question is, how can I translate a context to a system path.
For example a context is in the following path:
E:\xxx\yyy\myContext
The web-app is in:
http://localhost:8080/myContext
How can I translate that using a PageContext or something similar into

Re: cross context include
I guess we'll have to find a way of going over the 10,000+ pages. Maybe we can write a small program to automate it. I don't like dirty solutions :) If this is indeed a bug in our software, it should better be fixed. One last question though.

manager and admin applications
I had to make some modifications to my server.xml file, so that my default host (localhost) is no longer the Tomcat's default start page in webapps/ROOT. After this change, I can no longer reach my manager and admin applications. In my previous server.xml, I haven't noticed any settings regarding these two applications. So my questions is, how are these two applications deployed? And how can I make them work through a single domain name (i.e. tomcat1.domainname.com:8080/manager/status) ?

That fixed the problem. Thank you very much! Asim On Mar 27, 2004, at 1:19 PM, Parsons Technical Services wrote: Asim, I just did this very thing. The way I fixed things was this: I moved the index.jsp page to the root of the manager application. Now when I go to http://localhost/manager I get the old index page. I also moved the images so that they show up as well. I then edited the path information in the index.jsp by adding ../ in front of all the links to the local tomcat stuff. Thus: Tomcat Administration became Tomcat Administration The link for manager did not change. And with this all is well again. Now just point to your new url and it's like you never left home.

After this change, I can no longer reach my manager and admin applications. In my previous server.xml, I haven't noticed any settings regarding these two applications.

apache + 2 tomcat cluster memory problem
Hello everyone, I have 2 Tomcats (both 5.0.19) running on two separate machines. One machine also has Apache 2.0.49 installed on it for load balancing. Apache communicates with tomcat1 thru port 11005 and tomcat2 thru 12005. tomcat1 and Apache are on the same machine. Apache is set to forward /* to the load balancer (and then to Tomcats). We have over a hundred virtual hosts on our tomcats, so we don't want to worry about configuring Apache virtual hosts to serve the images and all the other files (that's why we forward /*, not just /*.jsp and /servlet/*). Both tomcats also have their http connector ports listening to port 8080 on their individual machines. We're using mod_jk_1.2.5_2.0.47.dll for Apache to Tomcat communication... Both our tomcats are running with the -Xms128m -Xmx256m options. With this configuration everything works perfect for about an hour, then our tomcats run out of memory... When we turn off clustering, and run a single Tomcat on port 80 (of course by shutting down Apache Httpd), we don't have any memory problems at all (for now, we're planning to use clustering to avoid down time, one server is actually enough to handle all the traffic). Does anyone have any idea why we'd run out of memory when our tomcats are talking to Apache through mod_jk?

Re: apache + 2 tomcat cluster memory problem
Thanks Filip. I only found the thread of mails starting March 17 with the title "Horrible memory leak in tomcat 5.0.19" If this is indeed the mails you advised me to look at, here is what I found out: Our setup differs in a way that we are using mod_jk 1.2.5 instead of 2.0.2. So mod_jk 1.2.5 + Tomcat 5.0.19 has a memory leak problem as well. This suggests that maybe the problem is with Tomcat 5.0.19 (?) Appearantly someone else (Robert Kruger) had exactly the same problem and it was solved when they downgraded to Tomcat 5.0.18. We cannot do that either because of a bug fix regarding session states in 5.0.18. I don't mind using mod_jk 2.0.2 as long as it solves our problem; however there already seems to be a memory leak with the mod_jk 2.0.2 + tomcat 5.0.19 combination as well. In Robert's email, he predicts that maybe the problem is related to JMX registration issue described in http://www.mail-archive.com/[EMAIL PROTECTED]/ msg53035.html. I'll reply to his email to see if it was indeed the problem. What's the next step?

Re: Horrible memory leak in tomcat 5.0.19
Hello Robert, We are having the same problem with mod_jk 1.2.5 and Tomcat 5.0.19. However, we cannot downgrade to Tomcat 5.0.18 because of a bug fix regarding session states. I was wondering, have you guys tried disableing the JMX registration? Was that indeed the problem? Thank you very much. Asim On Mar 18, 2004, at 4:08 AM, Robert Krüger wrote: Hi, we had the same problem (enormous memory leak which frequently made our production system crash), downgraded to 5.0.18 and everything went back to normal. Just yesterday a colleague of mine came to the conclusion that it is not too unlikely that it is the problem described in the message http://www.mail-archive.com/[EMAIL PROTECTED]/msg53035.html It that is so, you can simply disable the JMX registration of requests to get rid of the problem. We will try that probably later today but of course you can give it a shot yourself. There is not much to lose.

Re: Registry problems followed by OutOfMemory errors
Thanks for the quick reply! How can I turn off JMX request registration? I tried to find it in the Tomcat documentation, but all I could find was the MBean Descriptor How To which wasn't very helpful. I doubt that we need it. I will look into the resource problem. I doubt that we're running out of threads, because 1000 of them should be more than enough. Another resource problem could be the number of SQL connections, but on our SQL Side (MySQL), max_connections is set to 5000 which is about 7 times more than we need. Number of file descriptors might be a problem. For each web application, we have to load properties files and these files are automatically checked once every minute for possible updates. How can I configure the number of file descriptors? Thank you very much! Asim On Dec 10, 2004, at 11:02 AM, Shapira, Yoav wrote: Hi, Do you need JMX request registration? If not, turn it off by setting it to false in the configuration file. That'll save you some memory by itself. Your OOME is the root cause, so if you fix that the hundreds of others errors will likely go away. The OOME, in turn, is probably caused not because you're out of heap memory, but because you're out of another resource, such as file descriptors or threads.

OutOfMemory Errors
I'm trying to solve an OOME on our Tomcat. We profiled our application using JProfiler and there are no memory leakages on our end. Currently, I'm focusing on some system resource problems such as file descriptors. Would this be a valid problem on Windows Server 2003?

javac and Tomcat 5.5.4
We're using Tomcat 5.5.4 on Windows Server 2003 with Sun's jdk1.5.0. We have over 180 virtual hosts with over 20,000 jsp files. Our Tomcat is running with the fork = true option for compiling the files in a separate JVM. Here are our JVM parameters: -Xms1024m -Xmx1024m -XX:MaxPermSize=128m -XX:MaxNewSize=48m -XX:NewSize=48m -XX:+UseParNewGC -XX:+CMSParallelRemarkEnabled -XX:+UseConcMarkSweepGC My first concern is about forking. In the old days, when we were using Tomcat 5.0.28 with jdk1.4.2, I used to see multiple instances of javac.exe on Windows Task Manager while my JSP files where being compiled. Even though fork is set to true on Tomcat 5.5.4 with jdk1.5.0, I don't see any javac.exe instances any more... Is this normal? >From time to time (when there is plenty of JSP files to compile), Tomcat suddenly shutdowns with the following error: Background compile failed java.lang.OutOfMemoryError java.util.zip.Inflater init java.util.zip.Inflater79 Visualgc shows me very frequent fluctuations in Eden Space.

I have a very strange problem. Here is my setup: Windows Server 2003 Tomcat 5.5.4 Sun's jdk 1.5.0 build 1.5.0-b64 Whenever Tomcat serves a page from my site it gets into an infinite loop. This happens even when serving a simple html file, so I'm pretty sure that it's not related to my application. The strange thing is, even though it gets into an infinite loop (error messages don't stop on the command prompt), it serves the page without any problems. Here is my host setup in server.xml. XXX.com Can this be something to do with my URL? I don't want to provide it for now, but it's a 4 character alphanumberic URL in the AA##.com format (A = Alpha, # = Numeric)... I'm really stuck... Any ideas? Thanks, Asim PS: Here is some of my error log... ...

Valves
I'm using Tomcat 5.5.5 on Windows Server 2003. I have implemented a new valve. I include the following line in my My valve extends org.apache.catalina.valves.ValveBase Everything works fine on my Mac OS X. However, on Windows, when I start Tomcat as a service or from command line, it cannot find my object com.en.stats.StatsValve This is located under $CATALINA_HOME$/shared/classes/com/en/stats/StatsValve.class When I move it to commons, it finds that class; however this time gives an error message saying that it cannot find org.apache.catalina.valves.ValveBase This class comes with Tomcat. It is located in $CATALINA_HOME$/server/lib/catalina.jar How can I solve this problem? And why does it work fine on my Mac OS X? The configuration is exactly the same...

IIS Default Document
I've set up IIS 6 to serve jsp files through ISAPI Redirector 1.2.8. Everything is working fine except my default documents. How can I get IIS to server index.jsp files by default. Even though it's added to the default document list, it doesn't seem to work. Thanks, Asim - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
include / c:import problems
Hi, We're using Tomcat 5.5.7 on Windows Server 2003 with Sun's J2SE 5.0. >From time to time, we have problems with jsp:includes and c:imports. For some reason, the whole page gets included more than once. For example; on index.jsp, we have news.jsp and events.jsp includes. >From time to time here is what happens: index.jsp loads. news.jsp gets included. Instead of events.jsp index.jsp gets included. On that second index.jsp, news.jsp and events.jsp gets included successfully. We end up getting very weird looking pages. We have no idea why this happens as the code is correct. In fact, the page loads correctly after a refresh. This seems to happen once every 100 loads... Any ideas?

Re: include / c:import problems
Here is the web.xml at top level (Tomcat/conf/web.xml), there is
really nothing special about it. Our regular applications don't
really need web.xml:
http://java.sun.com/xml/ns/j2ee";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd";
version="2.4">

index.jsp
index.html
index.htm
JSP code uses cross context includes and it's really complicated
although there is nothing wrong with the code. We have 2 contexts.
Here is a sample index.jsp from context /
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core"; %>
Here is a part of header.jsp from context /apps
<%@ page contentType="text/html; charset=utf-8" language="java"
import="xxx.EC" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"; %>
<%@ include file="/shared/ec.jsp" %>
<% session.setAttribute("ts", new Long(System.currentTimeMillis())); %>
<% if (ec.isClosed()) { %>
window.location.href = "/apps/closed.jsp";
<% } else if (ec.isUnderConstruction() &&
ec.getHttpHost().indexOf("ednet.ws") < 0) { %>
window.location.href = "/apps/under_construction.jsp";
<% } %>
<%= ec.getWebsiteName() %>
" />
<c:import url="/shared/main.css" context="/"
/>
Please note that header.jsp in /apps includes another header.jsp in /.
The second header.jsp in / doesn't have any includes. It's plain
HTML code...
HPNews.jsp in context /apps is something like this:
<%@ page contentType="text/html; charset=utf-8" language="java"
import="xxx.EC, xxx.MySQLTable, xxx.StringUtils, xxx.News" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core"; %>
<%@ include file="/shared/ec.jsp" %>
<%
News news = new News(ec, pageContext);
MySQLTable newsList = news.getHPNews();
%>
...
<% if (version.equals("3") || version.equals("4")) { %>
<% } %>
...
Please let me know what you think. Thanks in advance!
