RE: Using shutdown script for different port
Back to my original issue--I was having trouble shutting down Tomcat when the shutdown service was listening to a non-default port, but have since sorted it out. After going through the source code, I found that when processing the shutdown command, the Bootstrap system just uses the configuration in CATALINA_BASE, so all you need to do change the port in server.xml, and make sure your shutdown script references the correct directory hierarchy. Thanks, Dhruva --- Steve Kirk [EMAIL PROTECTED] wrote: OK. I didn't realise that, although I suppose it's obvious in hindsight.

When is the connection pool actually created? * When Tomcat starts? * When the web application is started? * When you request the DataSource from the JNDI service?

RE: verbose gc
Check out Jeff Tulley's responses to my post OutOfMemoryError with Seemingly Plenty of Memory. You may also want to check out Sun's forums on the Java Virtual Machine. You will find a host of information on JVM tuning. As I said in my post, we would get the OutOfMemoryError about every 24 hours. I tried setting MaxPermSize to 256MB (haven't been able to determine the default value for Sun's JVM, but it's 64MB for HP's JVM). This sets the size of the permanent generation, into which longer-lived objects and class definitions are loaded (we have over 3500 classes over multiple web apps). I wasn't going to say anything to this list without being more certain, but Tomcat has been running with no problems since Friday afternoon (47 hours as of this writing)--the longest it's lasted all month.

RE: OutOfMemoryError with Seemingly Plenty of Memory
Well, I have made an assumption in most cases. The OutOfMemoryError is logged with no timestamp to $CATALINA_HOME/logs/catalina.out. We have a script that periodically (every 15 minutes) hits the applications and notifies us of any error response (either status above 400 or the word ERROR in the content). When I get such a notification, I immediately check the log file (catalina.out) for the OutOfMemoryError, and it is always near or at the bottom of the file. I know that in and of itself is no indication of when the error actually occurs. The applications themselves are set up to use syslog (through Log4J). Sometimes the OutOfMemoryError is logged here with a timestamp, and always occurs within minutes of my notification. --- Shapira, Yoav [EMAIL PROTECTED] wrote: Howdy, Although the possibility of a memory leak (sorry--unintended object retention) has not been completely ruled out (yes, I'm running the applications through a profiler), I'm quite puzzled that this problem would occur when, by all indications, memory use is nowhere near the limit.

OutOfMemoryError with Seemingly Plenty of Memory
I am troubleshooting an issue we've been having with Tomcat 4.1.27. We have several websites on one instance, and it regularly throws an OutOfMemoryError, requiring a restart of Tomcat. Some observations (warning--this is a bit long): * The box runs two 2.8GHz Pentium 4 Hyperthreaded Xeons, and has 2GB of RAM (recently upgraded from 1GB). * The OutOfMemoryError never contains a message (I believe an OutOfMemoryError is thrown with a message when the java process has used the maximum number of threads). * There is a single instance of Tomcat, housing 20 applications (including the ones that come with the standard distribution of Tomcat, examples, tomcat-docs, etc.--these apps see no traffic). * We have a servlet that is hit every five minutes. It calls Runtime.freeMemory(), Runtime.totalMemory() and Runtime.maxMemory(), after calling Runtime.gc(). This information is graphed (free, total - free, both vs. time). According to this graph, there is always plenty of memory available (I have seen the amount of free memory get quite low--below 1MB, but never when the problem occurs). * We're running Tomcat 4.1.27, Redhat Linux 7.3, Sun JDK 1.4.1_05. * Peak traffic is between 10:00 and 22:00 everyday. The heaviest day is Monday and the lightest Saturday. * Together, the applications service an average of 1600+ requests per hour. * Before the memory upgrade, we were running an initial heap size of 100MB, and max of 768MB. We are now running an initial heap size of 768MB and max of 1536MB. * Uptime used to be about 100 hours, but recently has fallen to 24 hours. This change does not coincide with any configuration change. I have not determined if there is a coincident change in traffic patterns. The memory upgrade has had no effect on uptime. * Before the memory upgrade, when the problem occurred I would find the java process spinning (i.e., processor use according to top was 99%), and it appeared to be using some swap space. Since the memory upgrade, no swap space has been used, and the spinning has not been observed. * At the time that the problem occurs, top reports that java is using 500-600MB of RAM. This has not changed since the memory upgrade. * Tomcat is set up not to refresh the context automatically. Although it is set up to refresh JSPs, we do not do this. No changes are ever made without restarting Tomcat. * We have the JSP compiler set up to fork (i.e., use another instance of the JVM). * The problem almost always occurs during hours of heavy use, although it has also been observed on Saturdays (the day of lightest use). * Diskspace use is nowhere near capacity. * For a few days, we ran Tomcat with verbose garbage collection (the verbose:gc flag). The problem seemed to occur just after a full garbage collection. Although the possibility of a memory leak (sorry--unintended object retention) has not been completely ruled out (yes, I'm running the applications through a profiler), I'm quite puzzled that this problem would occur when, by all indications, memory use is nowhere near the limit.

Context/DefaultContext Question
Thanks to all who responded to my OutOfMemoryError post. Among other things, it was suggested that I look at the reloadable attribute for the context definition. We define a DefaultContext in server.xml, with the reloadable attribute explicitly set to false. We also have, for each application, a separate context definition file, for which the reloadable attribute is explicitly set to true. I'm a little confused about these two work together. We have a JNDI resource set up in the DefaultContext for e-mail (see the mail/Session example in the JNDI Resources HOWTO) that is actually called mail/Session, with the mail.smtp.host parameter set to localhost. In the application-specific context, this same resource is defined by the same name, but with mail.smtp.host set to a different value. The application always uses the value defined in the DefaultContext. Is this because the same name is being used, and once something is defined in the DefaultContext, it cannot be overridden by an app-specific Context? Going back to the reloadable attribute, is each context that sets this overriding the value in DefaultContext? Thanks, Dhruva __ Do you Yahoo!?

From my experience, this is likely due to some sort of configuration error for that application.

OutOfMemoryError
We get OutOfMemoryError's on Tomcat 4.1.27, running on RH 7.3, Sun JDK 1.4.1_02 (with 512MB allocated to it) The box has 1GB of RAM, 2GB of swap space, and four Xeon processors. This error seems to occur during periods of low load (like during the Thanksgiving holiday), after which Tomcat exits. According to the calls Runtime.freeMemory() and .totalMemory(), it comes nowhere near using that much (we track it every five minutes by hitting a servlet that calls these methods). Has anyone seen anything like this? Thanks, Dhruva __ Do you Yahoo!?

Re: Multiple Tomcat instances for virtual hosts
This doesn't really answer your question, but we've found Tomcat to be quite robust. You may also want to find out (if you don't already know) what's bringing the server down. -d --- Thomas Eichberger [EMAIL PROTECTED] wrote: Hi, I have Apache 1.3 and Tomcat 4.1.8 on a Red Hat 9 machine. Apache serves several virutal hosts. We have one Tomcat instance running with several web contexts, one context for each virtual host. Now I would like to change this to have one Tomcat instance for each virtual host (this is necessary because Tomcat sometimes crashes, and I don't want all virtual hosts to be down then). I read a book about Tomcat and searched the Web, but could not find out how to do this. What I assume is: In Apache's httpd.conf I have something (after the import of mod_jk): NameVirtualHost 200.200.200.200 (or whatever) VirtualHost 200.200.200.200 ServerName www.xxx.com DocumentRoot /tomcat1/webapps/xxx JkMount /servlet/* worker1 JkMount /*.jsp worker1 JkMount /*.do worker1 /VirtualHost VirtualHost 200.200.200.200 ServerName www.yyy.com DocumentRoot /tomcat2/webapps/yyy JkMount /servlet/* worker2 JkMount /*.jsp worker2 JkMount /*.do worker2 /VirtualHost Then I will install Tomcat two times, in /tomcat1 and /tomcat2. The server.xml of each Tomcat contains different ports (for shutdown and for the connector for ajp13). The workers.properties should look like: worker.list=worker1,worker2 ... worker.worker1.port=8009 worker.worker1.host=localhost worker.worker1.type=ajp13 ... worker.worker1.port=8010 worker.worker1.host=localhost worker.worker1.type=ajp13 Is this all correct?

RE: heap size
I recently discovered these two methods, and was wondering how accurate they are. I am a bit confused: I am running Tomcat 4.1.18 on Linux, with JDK 1.4.1_03-b02. Nowhere in the startup scripts do I see it specified how much memory to use (i.e., with the -Xmx flag). When I call Runtime.totalMemory(), it gives me 128MB, yet I was under the impression that the JVM sets aside 64MB by default. On a possibly unrelated note, is it feasible to force garbage collection on Tomcat's JVM, either through Tomcat or the JVM itself? Googling has revealed only the official answer to this question, but I've heard that most profilers can do this. Thanks, Dhruva --- Shapira, Yoav [EMAIL PROTECTED] wrote: Howdy, Thanks Yoav - one last dumb question and I will leave you alone! So by There's more than one in this email ;) And no question is dumb (although that assertion is frequently tested on this list). adding that to my environment variables list, Tomcat knows to add it as a startup parameter for Java? Or do I need to specify something else in the No, it's one of a small set of variables documented in $CATALINA_HOME/bin/catalina.sh that tomcat looks for. Environment variables don't need to be on the classpath. Is there an easy way to check the JVM to see the parameters once it is running?? Generally, no, but there are some exceptions.

Re: where to get mod_jk2.so, jkjni.so
Assuming you're running Apache 2.0, unless you're running 2.0.42 or 2.0.43, the answer to your question is You don't. Unfortunately, the server against which these libraries are built must match the *minor* release on which you will run these libraries. You will have to download the tomcat connectors package (http://apache.ttlhost.com/jakarta/tomcat-4/source/tomcat-connectors-4.1.24-src.tar.gz) for your version of Tomcat and build it yourself.

Can't Build mod_jk in Linux

And copied the files jkjni.so and mod_jk2.so to Apache's modules directory. Am I missing anything else? Some of the documentation I've found mentions a file, mod_jk2.dsp, but the contents of the file itself suggests it's only for Win32. Is this true?

I think the original poster meant Windows XP Professional. Java in general does not deal with spaces in file and directory names very well.
