Re: thread dump analysis
Hi, Saw your message on the boards. Did you make sure you have this environment variable set? On systems that I need it, I put it in my tomcat startup file. LD_KERNEL_ASSUME=2.2.5 Check out my howto page for my brief notes on threading and it's potential problems with JVMs and threads. http://www.linuxjava.net/howto/webapp/ Oscar On Tue, 17 Feb 2004, Daniel Gibby wrote: My tomcat 4.1.29 instance running J2RE 1.4.1 IBM build cxia321411-20030930 on RedHat 9 kernel 2.4.18-14 keeps gaining processor usage until finally can't answer requests successfully.

However, in this tomcat case, I can't see anything like that where something is waiting in circles... even though I wouldn't rule that out. My experience on reading thread dumps is limited... Anyway, can someone who has better experience tell me what is consuming the CPU? Restarting tomcat brings the load back down, and it slowly goes up again... like over a few days to a weeks time it is back up to 8.00 Load Average. I won't include the whole file.

Re: HTTPS with Apache 2.0.48 and Tomcat 5.0.16
Hi, I assume that's an Apache error your getting. If that's true, then that means it's not mapped to Tomcat. I don't know anything about the mod_jk2 syntax, which sounds like the problem. Do you do the proper include for the workers2.properties in httpd.conf, which I assume you need to do? Alternatively, if you've gotten it work in both HTTP and HTTPS, you can redirect HTTP to HTTPS.

The Apache HTTP server does have a Thawte certificate. My next idea is to try to install that same certificate on Tomcat. But I don't think that's going to do it entirely. Here's some of the code that writes out the PDF: ByteArrayOutputStream baosPDF = null; ... ServletOutputStream sos; sos = resp.getOutputStream(); baosPDF.writeTo( sos ); Can someone give me a pointer on what would have to change to encrypt the PDF so that the browser will stop complaining about nonsecure items? I can't have the 'nonsecure items' prompt, and I assume I will need a known good certificate-- can I use the same one that we're using on Apache? Or am I headed in a completely wrong direction?

RE: Back to the nonsecure items problem
I imagine it might just be a poor implementation in IE. It might be doing something stupid like determining that the inclusion of a mimetype is nonsecure. It doesn't make sense that anything could go through http when accessing via https, without a link in your page that points to somewhere else. To make sure, you could disallow http access to the site completely, and/or block port 80 at your firewall. Otherwise, I'm sure there's a security hole in IE that you could make it think that anything from anywhere is secure. :) Oscar On Tue, 3 Feb 2004, Wendy Smoak wrote: From: Oscar Carrillo [mailto:[EMAIL PROTECTED] I've noticed this too when including a Flash application.

Re: Tomcat 4 and Linux SMP

I believe you need to setup a VirtualHost section in httpd.conf even if you don't really need Virtual Hosting. Also try Redirecting the whole site. I'm not sure if I've tried just the webapp. I'm not sure if you need to compile the rewrite module for the redirect, but I don't think so. #httpd.conf VirtualHost section of myhost.mydomain Redirect / https://myhost.mydomain/mywebapp Also, you can't include the mod_jk configuration. You must put the mount commands explicitly in each virtual host. If you include the modjk conf file Include mod_jk.conf, then it will be global and all hosts will get access. This is likely your problem especially if you haven't put mod_jk mount commands in ssl.conf. Oscar http://www.linuxjava.net/howto/webapp/ On Mon, 2 Feb 2004, Ralf Schneider wrote: Am Montag, 2.

You're right it's for mod_jk. But the httpd.conf would mostly be the same, which is where your problem is. You must only mount (no global include mod_jk2.conf) the webapp in ssl.conf, and additionally you can redirect http to https in httpd.conf so that ppl automatically get moved to https.

Subject: Re: Tomcat5 RH ES mod_jk2 Apache2
Well. I have gotten Tomcat5, RH ES, mod_jk2, and apache2 all working.
I've come to the conclusion that the clowns
who developed this stuff sit back and watch the traffic on the list and
laugh. Here is what you need to do in your workers2.properites file:
For every servlet you need to define a worker in worker2.properties.
[uri:/servlets-examples/*] This won't work, but this will
[uri:/servlets-examples/servlet/HelloWorldExample]
[uri:/servlets-examples/servlet/RequestInfoExample]
etc.
[uri:/servlets-examples/servlet/*] won't work
[uri:/servlets-examples/servlet/*.*] won't work
[uri:/servlets-examples/servlet/*e] will work, but all of your servlets must
end with the letter 'e'
Unless one of you fine developers want to clear this up. I'm going to
switch to Jetty. Tomcat is crap!!!

Curious...Send me your entire workers2.properties file and I'll have a

Also, what are the urls you are using to access your html/jsp/servlets?

free to use 'localhost' if you don't want to reveal sensitive server
hostname/ip's

you don't need

Add the following under [channel.socket:localhost:8009]
host=localhost

and under [ajp13:localhost:8009] add this
channel=channel.socket:localhost:8009
Before you go about making those changes, make sure that your servlets
are working OK on standalone tomcat :)
Good luck,

Re: HOST - DNS setup
I'm not sure what you are after. But... You could put Apache in front of Tomcat. Have Apache mount the appropriate Tomcat apps so that you would be able to type in. http://mycompany.com/firstapp Or you could setup a Virtual Host for each time you wanted to do: http://firstapp.mycompany.com/ It may not be that much different but it does mean you don't have to touch Tomcat configuration when deploying, just Apache. Oscar On Thu, 29 Jan 2004, Kal Govindu wrote: Hi all, Our company has just started into Java based web applications. Our current methodology for deploying to production is to setup a DNS like say firstapp.mycompany.com and define a Host entry in the server.xml with aliases to respond to the new DNS.

But this is kind of cumbersome and time consuming setup when ever we deploy to production. As we have more applications this way we will end up with several Host's which does not seem like a good thing. Is there a better way to do this? Please help.

RE: Calling a JSP from a virtual host
To follow up here, I setup Virtual Hosts in Apache and have each Virtual Host have it's own webapp. I also tried it so that each Virtual Host uses the same webapp. In addition, I setup https (cannot do virtual hosts for https), and it has it's own webapp. It sort of works like virtual hosts in that connecting to https://www.domain1.com and https://www.domain2.com each connects to the same webapp. It should pretty much work like I put on my website, but I'm going thru it and soon putting up a more accurate account.

It turns out that not only did those two (production!) machines suck, but two QA machines and one dev machine (all the same) sucked, too. They all died when we put them under high load.

Redhat9 / mod_jk2 builds from source
Hi, The info I've seen on this list about building mod_jk2 has been for rpm installation. Here's the info I gathered so far trying to do Apache and the connector all from source. Building Apache2.0.48 and mod_jk2 (2.0.2) works seamlessly the following way: If you built Apache from source, such as in my HOWTO: http://daydream.stanford.edu/tomcat/install_web_services.html this will build mod_jk2 from source. I haven't tested the connector yet, but no edits to the Makefile were required to build mod_jk2.so. I used this configuration script and make command in: tomcat-connector-source-dir/native2 ./configure --with-java-home=/usr/local/java/java --with-java-platform=2 --with-apxs2=/usr/local/apache2/bin/apxs --with-tomcat41=/usr/local/jakarta-tomcat-5.0.16 --with-jni --with-apr-lib=/usr/local/apache2/lib --with-apr-include=/usr/local/apache2/include --with-pcre make all Then jkjni.so and mod_jk2.so will be in: tomcat-connector-source-dir/jk/build/jk2/apache2 Hope that helps someone. BTW, trying do it with the ant build seemed hopeless. I quickly abandoned that method. Oscar - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Cool. Questions inside.

Oscar,
Not a problem :-)
I do have some additions to my original post. The
changes get UNIX sockets working as well as IP
sockets.
Set the following environment variables:
export LDFLAGS=-lgdbm -lldap -lexpat -ldb
What's this need for? If it compiles, does that mean it's not necessary?
export CPPFLAGS=-I/usr/kerberos/include
-I/usr/openssl/include
Is this only neccessary if you want to do a secure mod_jk2 connection to a
separate machine running tomcat?
(all on one line for the second command). Use the
appropriate command for the shell you're in.
Tell configure about OS-specific files for Java JNI.
For linux and the Sun JVM, the files are located in
include/linux underneath $JAVA_HOME. The configure
command for mod_jk2 is then:
./configure --with-apxs2=/home/apache/bin/apxs \
--with-tomcat41=/home/tomcat \
--with-os-type=include/linux \
--with-jni \
--with-pcre
I originally tried that --with-os-type=include/linux but it gave an
error. It recognized that it was in a Linux environment so it seemed
unnecessary.
Finally, modify the JK_LDFLAGS line in
server/apache2/Makefile to include libaprutil. It
will read:
JK_LDFLAGS=-L${APACHE2_LIBDIR} -lcrypt -lapr-0 -lpcre
-lpcreposix -laprutil-0
(again on one line).
Run make, and the resulting mod_jk2.so / jkjni.so will
support both IP socketes and UNIX sockets.
In-process communication will probably have to wait
until a new MPM module is out for Apache.
The missing aprutil-0 library is probably due to an
autoconf / configure issue. The developers (according
to folks on this mailing list) have decided to use the
Apache apr interfaces, but have not finished updating
the configure scripts. This is really apparent if you
try to build the connectors from the current CVS.
What does aprutil-0 provide?
Thanks,
Oscar

Re: Calling a JSP from a virtual host

Re: Redhat9 / mod_jk2 builds from source
Interesting... I only get this with apache 2.0.48 from ldd /usr/local/apache2/lib/libapr-0.so.9.5: libc.so.6 = /lib/tls/libc.so.6(0x4200) /lib/ld-linux.so.2 = /lib/ld-linux.so.2 (0x8000) I guess that means I didn't build with the LD_FLAGS that you mentioned. The include-os-type=include/linux would give me an error in configure. I imagine that was because there was no directory in the mod_jk2 directory for that. Is that something that's only available with the CVS version? Anyways, thanks for the info and good luck finding employment.

I think that if you get libapr and libaprutil built with the listed environment variables you should not need them when building mod_jk2.so and jkjni.so. Messier details are probably better discussed by the developers who know the internals of this code. I'm just beginning to look at it for the following reasons: 1. Submit a patch for autoconf to get the right configure script built. 2. Look at a new MPM module in Apache for Linux and the new thread model that will support in-process communication.

RE: Tomcat / Apache / SSl
You will use the same connector over port 8009. No additional connector needed over any other port. In your ssl.conf for apache, you will create a VirtualHost entry very much like the one that's in your httpd.conf file. In there you will do your JkMount declaratives, etc. BTW, I use 0.9.7c openssl because that one is patched for a vulnearability. Just thought I'd mention it eventhough you list yours as Nov 4, which probably means the patch was backported.

I'll be putting the setup procedure and benchmark results here: http://daydream.stanford.edu/tomcat/install_web_services.html What was meant by Linux 2.6? Was that Debian or Suse? Oscar Does anyone have stability issues on this platform (without any LD_ASSUME_KERNEL, and with Sun JDK 1.4.2 or similar very recent VM) ? I'm trying to compare with Redhat 9 and see if the troubles also happen with that (cleaner) platform. Bonus question: How's the performance / scalability ? I've been running Linux kernels 2.6.0 on a couple of very lightly loaded Tomcat servers without any issues. This is running on Fedora Core 1 and JDK 1.4.2_01-b06 (which reminds me, I should upgrade that machine to the latest JDK, 1.4.2_03-b02). No LD_ASSUME_KERNEL env vars set. I also have a Redhat 7.3 with kernel 2.6.0 server running Tomcat with JDK 1.4.2_02-b03 with no problems, but again it's a development server so no real load. I haven't done any performance / scalability tests but theoretically it should be a lot better than 2.4 kernels. BTW, I'm not sure what platform you really mean by Linux 2.6 as that isn't a specific platform, but any Linux distribution running a 2.6 kernel. -Dave - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Enabling SSL on specific URLs using IIS and Tomcat

RE: Linux Kernel 2.6.0 success
There are advancements that may prove beneficial. It should be much better in handling threads. From what I remember, orders of magnitude better. I think hundreds of thousands of threads can now be handled nicely. I imagine that this would translate into better handling of multiple connections to Apache and Tomcat. If I remember correctly, this is due to the new O1 scheculer. Also, memory handling is supposed to be much improved. Handling of multiple processors is supposed to be much improved so that should translate into a better server in all respects. It's also a better desktop environment too, because it handles multiple processes much better so it feels more responsive to the user. I can vouch for this, as I can burn a DVD and play a FPS game under wine without noticing. I'm not planning on doing any benchmarks, unless someone knows of or provides me with a war file to deploy and test. BTW, today I added to the mix Postgresql-7.4.1 via JNDI with dbcp-commons-pool.

RE: Have some questions, also possible contract work up for grabs
Do any hosting companies offer reasonably priced colocation or flexible accounts with tomcat, php, and mysql installed? The IT company I work for has developed a great piece of software using JSP and Java technology but we need to get it onto a good box for production use. Waste of money and time. As someone else said - build your own and co-locate if necessary. Even if you did manage to get someone able to install/support tomcat and mysql, you'd probably pay through the nose for actual support (i.e. when something goes down). Far better to be in total control. PC's are not expensive, and a good OS (unix/linux/solaris) is not expensive. Co-locate? probably expensive, but still cheaper than what you would pay for REAL hosting (i.e. that worked when things broke). Cost of building your own and KNOWING what's going on... priceless. Co-locating can be pretty cheap, but someone has to setup all the stuff. Whether you do it yourself, or pay someone, all depends on your needs. I agree with you on handling your own installation, but there is a trade-off of time obviously. Does anyone here offer services such as using SSH to install Tomcat remotely? We would be willing to pay for someone to install Tomcat in a short timeframe. I doubt it. Most ISP's cannot even support PHP or perl, let alone tomcat/mysql/java. Some ISPs will, but you are probably better getting a sub-contractor who has a relationship with the ISP. Your small-to-medium datacenters I think are better for this. The ideal person would be someone that knows Tomcat installation quite well. We have installed it on a couple boxes, but usually by a lot of trial and error. We would like to get it up and running properly very quickly. Sorry to say this, but spend time with the docs and spend time doing the builds yourself. If anyone is interested, please send me an email and I can send you the details. I apologize in advance if this is not the place for an email like this. I figured this was probably one of the best places for an experienced Tomcat userbase. As long as you don't want to integrate Apache and Tomcat, you can email me. I will not put both on the same machine, after finding that the web server was killing tomcat performance (due to the number of web hits). I split Apache off to it's own server, and used a simple firewall (appliance) to forward port 80 requests to one machine, with port 443 (SSL) to the tomcat server. Secure application access, no hit from the web server. Some people like me don't have Apache doing much except passing the request over to Tomcat. In this case, I doubt it would benefit much to have Apache on a different box. I like Apache mostly for the more tested environment and handling of SSL, Virtual Hosts, etc. Oscar - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Hi, Ok, I just did it for about the 5th time (mod_jk) on a completely new installation. I even have it running with the new and improved kernel 2.6.0! I'd say the common mistakes are: 1. Not removing the RPMS that will conflict, such as httpd and tomcat. 2. Not updating the critical updates first. nptl-devel and glibc primarily. 3. Trying to do a mixture of RPMS and build compiles. 4. Not setting LD_KERNEL_ASSUME=2.2.5 in case you have problems with threads. Personally, I'm not convinced that this is necessary in all cases. 5. Not configuring your environment variables right from the start 6. Then of course messing up the syntax of the config files.

Fedora (RedHat) Linux and gcj
I saw this in Fedora 2 release schedule. We have set a very aggressive schedule for Fedora Core 2. Red Hat considers two items absolutely stop-ship -- that is, we will slip the release if necessary to include them. These two items are the 2.6 Linux kernel and SELinux functionality integrated into the distribution. Other areas of technology that the Fedora Community (Red Hat and third parties together) will focus on will include GNOME 2.6 (tight schedule, particularly dependent on Gtk+ 2.4), KDE 3.2, more Java software using gcj (Ant, Tomkat, Jakarta, Eclipse, but not Mozilla plugins, AWT, or Swing), and integrating work on other architectures (at least AMD64, and possibly also SPARC). Does anyone have any ideas on Tomcat running under gcj? Does it work well already, and would we expect real performance benefits from it? Since Tomcat (Tomkat) isn't spelled correctly in the release schedule, I don't have a lot of confidence that this means anything.

RE: Need some Tomcat Configuration help badly
Hi, If I understand this correctly, there are references lying around that point to objects that no longer are needed. Is this something the developer does or something tomcat does in compiling the servlets? In other words, is there something the developer or administrator can do to avoid this? Does pre-compiling the jsp files avoid this? Another thing I'm not sure I understand is this: If you don't change the JSP pages, or class files, then the memory leak that is created just happens once.

RE: Need some Tomcat Configuration help badly
Thanks for the clarification.
This seems reasonable, as I thought it would be unlikely in most
circumstances. Not properly closing/de-referencing external resources,
including threads would cause the JVM's memory to grow. JDBC resources
would probably be the most common.

Howdy,
Sure, here's one example:

Thread myJobThread = new Thread(new MyJob());
boolean goAhead = evaluateSomeCondition();
if(goAhead) {
myJobThread.start();
} else {
System.out.println(Not running job.);

}
Because creating a thread allocates some resources and adds a reference
to the thread in its parent ThreadGroup, when the method is done the
Thread cannot be garbage-collected even though the myJobThread reference
is gone. A simple fix might be to do the thread creation inside the
goAhead clause.
This is only to show it's possible. Obviously this is not an example of
good practice, but it's an easy enough mistake to make ;) The above is

Re: Tomcat performance on Windows versus Linux
I am about to setup Tomcat under a new Linux 2.6 kernel with 2 Athlon MP processors. Since scheduling, threading, and SMP have been much improved in the new kernel I wonder if it will add to performance. I don't have anything to test the new setup with, but if anyone has good ideas (and by good, I mean easy), as I haven't done any profiling, etc. Oscar http://daydream.stanford.edu/tomcat/install_web_services.html On Mon, 15 Dec 2003, Sean Dockery wrote: Thanks, Tim, for the even handed response.

I received a response in email from Peter Lin in which he details his experience (which was very helpful; thank you, Peter). I've read Peter's article about performance tuning and a few other white papers as well, but I haven't really seen anything in the past that focused on OS differences and how those differences might affect the recommended approach to profiling and tuning. My conclusions from my readings so far: Slow java code (i.e.: algorithms) will be slow on any platform; change the implementation to make it faster. Configurable behaviour dependent upon OS services (TCP/IP stacks, threads, file I/O, etc...) should be tuned for the platform on which the application will live.

My guess is that this claim is based upon the supposition that thread/context switches under Linux are faster than under Windows. I find the claim rather dubious because I've never seen data to support the claim, but doubt is not certainty. Is there any evidence that this claim and other component performance differences between the Windows and Linux platform exist and are significant enough to throw my performance measurements out the window. :-) My concern is that I'll profile the application under Windows and tune it, but then find that my gains aren't as significant or maybe even worthless under Linux. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Ok, I read the PostgreSQL docs. It looks like AMD64 version is only workable under kernel 2.6. The good thing about the new kernel 2.6 is that FWIK you can have as many process/threads as you want cause it handles order of magnitudes more than kernel 2.4. I would also watch blackdown.org release schedule for their 64-bit version of the jdk/jre. IMHO, they know Linux a lot better than the Sun group does and are less combative with Linux.

I use chkconfig to make the sym links for the different runlevels, but you can just read the chkconfig line comment at the start of the script and do it yourself. I'm not sure how Solaris handles the runlevels sort of thing (Sys V, etc.), but it should be fairly simple to adapt. http://daydream.stanford.edu/#daemons Oscar On Sun, 23 Nov 2003, Tom Bartos wrote: Does anyone have any scripts to start and stop tomcat during system boot and shutdown?

Re: Slow on Linux
I'm no expert on Servlets so I'm not sure what's involved with all those calls, but it doesn't seem like it could be anything that takes 500ms. Have you tried running top while this is going on? You can set it to update quickly so that you can see what's taking up the processor, if anything. In particular, if it's a java thread (process) or Apache process. Are you compiling Apache and connector from source? Have you compiled a new kernel? Have you done all the updates to Mandrake? In particular nptl, gcc, glibc, and kernel. I don't know if many people are using Opteron here. You are picking a pretty new hardware architecture for your first Linux experience.

Re: Slow on Linux
Hi, You could buy an Enterprise edition of a distribution that supports AMD 64-bit. It does not seem to be quite ready in the main distributions. If you aren't willing to compile a new kernel, then I would not recommend going to native 64-bit AMD. Even if you are willing to, you might encounter some problems. And I don't know how much benefit you'd have without compiling any server software you are using. I'm also not sure what performance is like with Sun's or other's JDK. The JDK is probably what I'd be most concerned with performing under AMD64. If it's not good now, it will probably be good soon, since Sun is releasing servers with Opterons. But I don't even see that there is a JDK available for AMD64, so I can't imagine you'll gain anything by all the work being done mostly in Java under 32-bit. See this account: http://www.osnews.com/story.php?news_id=4618 BTW, I'm putting up a new server soon and I will be using dual AthlonMP processors.

Re: Installing jakarta on linux RH9
Interesting. I wonder if that's all it is. Any wish to elaborate if you are not using a connector to Apache? I was assuming everyone who was using tomcat on such heavy loads would be using Apache in front. BTW, if by any chance you're using the daemon scripts off my site, you would be using the LD_KERNEL_ASSUME=2.2.5 I set that because you definitely need it on RedHat 7.3, and I don't have a RH9 server in production yet. I'm probably also too afraid to change it even now though. http://daydream.stanford.edu/tomcat/install_web_services.html Oscar On Tue, 4 Nov 2003, Christopher Schultz wrote: Remy, No, on RH 9, all VMs will actually need the LD_ASSUME_KERNEL env variable (look in the archives for the details on the problems and the workaround).

The problems are with the HTTP/1.1 connector (it dies after about one day, regardless of the load). Also, there has been a GLIBC update which could have fixed the issue, so if you keep your system fully patched, you could be ok.

For those in Daylight Savings Time zones, remember you've got an extra hour to read the list :) Just wondering if anyone has experience with Tomcat and Linux kernel pre-2.6. It looks like this kernel is going to go mainstream soon, so I'd like to know what to expect. Linus Torvalds has said there will probably be one more minor revision and then the next will be 2.6. By my rough estimates that puts it at about 1 month away. Don't mind being the first to try it out, but I'm thinking there's others who already have. If so, what's your experience? Oscar On Thu, 23 Oct 2003, Oscar Carrillo wrote: Has anyone tried running Apache/Tomcat with the new 2.6-pre kernel? Or for that matter, has anyone ran it under the mm, or O1 scheduler patches? I'm also planning on running it with a dual AthlonMP system. Has anyone had any experiences with that, good or bad. I assume it should be no problem but any feedback would be appreciated.

Re: Unable to find servlet class after reload
Your load on startup is in your applications web.xml file? Are you saying it works fine the first time you start Tomcat? If so, then maybe it doesn't get shutdown propertly, when you restart. Or do you mean just reloading the application? There's supposed to be a patch to Tomcat for fixing reloading issues, but I don't know if this is one of them. I use startup servlets in Struts, but I don't have my app setup for reloading.

Re: Unable to find servlet class after reload
Agreed. If you only look in the directory that apache.org links to, you'll see the main download but you won't see the hotfix. Only if you click on the binaries folder will you see it. I now mention it on my HOWTO page: http://daydream.stanford.edu/tomcat/install_web_services.html Maybe others like John Turner can add it as well.

Re: mod_jk 1.2 binary for Linux?
I would recommend compiling it, and it doesn't seem that there's a linux binary available for download. I will be adding JK2 tutorial (only JK1.2 for now) shortly on my site, but looking at it now and John Turner's site, you should be able to figure it out.

RE: tomcat jitters, then hangs - please help
Have you updated the nptl-devel and glibc package for RedHat9? And are you running the stock kernel or have you built a new kernel? Are you using Apache in front of Tomcat? I have a suspicion that the stock redhat kernel does something strange with threading that a built kernel wouldn't do. I built Apache with modjk under the RH stock kernel. Then built my own kernel and Apache wouldn't load the modules anymore, and I think it's because of something weird they do with threads. Oscar On Fri, 24 Oct 2003, Ryan Lissack wrote: Hi all, Just an update on issues we were experiencing when running Tomcat on Red Hat 9. As mentioned previously in this thread, the problem appears to be with a bug in NPTL. In order to revert to standard Linux threads you can set the LD_ASSUME_KERNEL environment variable to 2.2.5 or 2.4.1 We set LD_ASSUME_KERNEL to 2.4.1 on one of our servers one week ago and, since then, have *not* had one outage, our other machine which does not have the environment variable set has had numerous outages during the period. We can confirm that this does appear to resolve the issue. I believe Noam Camiel found that setting LD_ASSUME_KERNEL to 2.2.5 also works.

RE: Removing extra white spaces in source
I knew what you meant. I was just playing along :) I have noticed an excessive number of newlines in jsp pages though, when everything in the jsp page gets resolved. The strange thing is that whitespace shouldn't make a difference on how most things get displayed in browsers, but they often do.

Re: Removing extra white spaces in source
Is is feasible to have Apache clean them up since I assume it has to get a text file at some point to pass along? Or even an option in mod_jk to clean it up.

Generated servlet is a .class file and I would be very reluctant to diddle with the tomcat generated .jsp files.

Oscar Carrillo's HOWTO
I've recently updated my HOWTO page for installing web services in Linux. Like John Turner's the crucial packages are built from source. The following installs and configuration are described in detail and been tested in RedHat 7.3 and RedHat 9. Tomcat 4.1.27 Apache 2.0.47 Mod_JK 1.2.5 Openssl-0.9.7c Struts 1.1 JDK 1.4.2 Ant 1.5.4 Postgresql 7.3.4 PgAccess 0.98.8 http://daydream.stanford.edu/install_web_services.html In particular, I'm contemplating creating either a build script, and/or source RPMS, to install all of these packages in one fell swoop. If enough people email me with interest for such a thing I will do it. You can email me off my web page, it's at the top of the page. I'd put it here, but I try not to expose my email too much.

Linux Kernel 2.6 and other info
Has anyone tried running Apache/Tomcat with the new 2.6-pre kernel? Or for that matter, has anyone ran it under the mm, or O1 scheduler patches? I'm also planning on running it with a dual AthlonMP system. Has anyone had any experiences with that, good or bad. I assume it should be no problem but any feedback would be appreciated. As a side note, I built Apache with a stock RH9 kernel and after compiling a new kernel, apache couldn't load the modules. I compiled it again and all was fine. But I thought it be good to post it here in case others have the problem too. Thanks, Oscar - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Linux Kernel 2.6 and other info
BTW, I never have any problems with migrating from one built kernel to a newer built kernel. The only time I've ever had problems was moving from a stock RH kernel. Maybe RH stock kernel does something a little differently with threads. Of course, this is why it's better to compile from source instead of using RPMs for such crucial packages. Or should I say, that's one reason why some of us prefer installing from source. We never know exactly what RH is doing in some areas. Most of the time we don't want to know, but in something like this I feel better knowing what's going on underneath, and therefore being able to do something about it when something goes wrong. And personally I don't think or expect RH to much care about breaking Apache/mod_jk/Tomcat/Java when they want all those people to be paying for RH Enterprise and customer support. Anyways, I actually think people are better off, and helping the community, if they compile certain packages from source. I guess this turned into my 2 cents :) Oscar On Thu, 23 Oct 2003, Oscar Carrillo wrote: Has anyone tried running Apache/Tomcat with the new 2.6-pre kernel?

Re: IBM JRE 1.4.1 dumping core on login with http/1.0 browsers

Re: Tomcat Crashing on Linux
You might want to look at how many processes/threads are listed for tomcat and your database. You might see that one of them or both is creating and keeping too many threads around. At least that would be a start. For tomcat, I have a daemon script that has a status command that tells you all the pid's of processes for tomcat. You can get it off my web page: http://daydream.stanford.edu/tomcat/install_web_services.html You can just use the command I use for that which is on the web page also. You should do something similar for Oracle to see how many processes are in the process table. You could try and restarting the database, which would clear out connections that aren't timing out, and see if tomcat starts responding again. You say it's crashing, but is it really? It clearly has problems restarting and is not responding. But that may not be the same as crashing. Are there processes showing tomcat is still up?

Re: Tomcat Crashing on Linux
Another thing that I do during development, with only myself accessing the site, is do things on the website that will require a database connection. I keep doing them over and over, and if more database connections are created I know something is wrong. Because since I'm the only one connecting, it should be using a member from the database pool and putting it back each time. If anything you do on the website that accesses the database, starts to cause more database connections, then members of the database pool aren't getting returned probably.
