Tim, Do you have a code example of this solution? I would be very interested in setting something like this up. Thanks.

Use a backgorund thread to do the processing. Then spit a page back to the user which uses a meta refresh to check the status of the background thread.

I am using tomcat 4.1 with apache 1.3.9. In one of our applications, when a user logs in, we will determine if the account's email address has been verified or not. If not, the application will ask the user submit an email address for verification using JavaMail. The process to verify the address is to send an email message to the email address immediately. Most of times, the process is quick and we can get the real time info about whether or not the user account on the mail server is valid or not. But sometimes when the user's email server is down or slow, the process could take pretty long time to finish. In the later case, Tomcat's max processors could be used up and 'no processor available' error is thrown. I guess I can increase the maxProcessor number in server.xml (currently it is set to 75), but it seems not the ideal way. I am wondering whether or not I can spawn a new thread in the servlet and hand the email verification to the new thread for processing, then the main thread will return and be available for new request to reduce the 'no processor error'? One problem I can see is that even I can do what I stated above, some document suggest that after the main thread returns (for example, exit from the doGet method of a servlet), the HttpServletResponse's outputstream is closed and I can't send response to the user anymore. Is this right? Any suggestions for my situation.

Tomcat 5 clustering
For the sake of this question, let me assume that I have an application running on one instance of Tomcat that takes 10 seconds to complete a client request. If I cluster 10 machines together does it help with the through-put, i.e. meaning it might take 1 second to complete the request now, or does it just make the session redundant in case of failure. Just wondering about which setup would serve me the best and be the fastest for our clients. Thanks for any input on this.

Tomcat on Linux HOWTO
Hope this helps someone out there. I sure appreciated all the help I received from people when I was going through this and trying to get things setup right and working. I have written a student assessment program using the Struts framework. This program will be used by over 70 school districts in the State of Oregon. I have a database backend and want to run several instances of Tomcat using Apache2 as a load balancer between them. I didn't need apache to server any pages, I just wanted it to do load balancing between my tomcat servers. I have 2 machines, M1 and M2. On M1 I run apache and 2 instances of the tomcat server. On M2 I run my 3rd instance of tomcat. I am running Linux 8.0, Apache2, Tomcat 1.24, j2sdk1.4.1_03, and mod_jk2 using channelSockets. I could never get jni or channelUnix to work on Linux.

S71tomcat, and made a link in the init.d directory to
this file under the name tomcat.
This does not work and I don't understand why not. If
I type at a terminal tomcat start, Tomcat starts
with no problems. What could be going on?

RE: mod_jk only loadbalancing to one machine
I had the same problem with load balancing using mod_jk2. I found that changing the lb_factor made a difference. If I set the lb_factor in each of my connector descriptors, all requests went to the last linux box that was defined. I have 3 instances to load balance, this is what I did for now: Connector port -- 8009 on machine1 -- lb_factor=2 Connector port -- 8019 on machine1 -- lb_factor=2 Connector port -- 8009 on machine2 -- lb_factor=1 It doesn't give me the straight 'round robin', but it does mix it up at least. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Rick Carter Sent: Friday, June 20, 2003 11:09 AM To: [EMAIL PROTECTED] Cc: Jeff Cousineau Subject: mod_jk only loadbalancing to one machine Hi, My problem in brief: one RedHat Linux box running apache with mod_jk trying to do load balancing to four boxes behind it. All requests only get sent to one of the boxes. The logs look good; if I remove that box from the config., it will pick one of the other three and send all requests there. It sticks with whatever box it picks even after a service stop and start. I've looked all over the web and my load balancing configuration looks just like everyone else's from all I can see. Boxes are all running RedHat Linux Enterprise ES 2.1. The four background boxes are running tomcat4-4.1.24-full.2jpp . Load-balancing box is running apache 1.3.27 (built with OpenSSL 0.9.7b and CFLAGS=-DHARD_SERVER_LIMIT=1024), and mod_jk 4.1.24. I have watched /usr/local/www/mod_jl.log, and all looks normal. I have it running debug so it gets very long very rapidly. I'll include it right after startup at the bottom though. At the moment, everything is going to server-c (worker3). That has persisted across several service stop and service start's, and a reboot. OBTW, after poking around websites and list archives, I've tried the worker.list being just loadbalancer and also having loadbalancer,worker1,worker2,worker3,worker4 -- either way, same result (although the first way produces a shorter mod_jk.log by far).

Michael -Original Message- From: Mark Eggers [mailto:[EMAIL PROTECTED] Sent: Saturday, June 07, 2003 10:56 PM To: Tomcat Users List Subject: Re: Help Please: Starting Tomcat using channelUnix with mod_jk2 Pascal, I've been trying the same thing with Redhat 9, and getting a similar problem. I even put /home/apache/lib in /etc/ld.so.conf and ran /sbin/ldconfig -v. I verified that that shared libraries are indeed loaded. I also tried modifying /home/tomcat/bin/catalina.sh to include a -Djava.library.path=[various things], but that failed to work as well. I'll think about it some more tomorrow. One thing to note: In the source code, there has been a recent change from apr_MD5FINAL to apr_md5_final. I'm wondering if the propagation has made it all the way through. /mde/ just my two cents . . . . __ Do you Yahoo!? Yahoo!

You need to have libapr on your LD_LIBRARY_PATH when you start Tomcat.

RE: Help Please: Starting Tomcat using channelUnix with mod_jk2
Thanks Chong, I did have the apache2-devel package installed, but I started a fresh install of Linux 8.0 and all the rpm's following your instructions again anyway. I'm ready to pull my hair out I get the same error about the undefined symbol: apr_md5_final I am using sun's j2sdk instead of IBM's, other than that, I think everything is the same setup as your system. I've done symbolic links, set environment variables, and everything else I can think of, but I get the same error. This seems so simple, I can't believe it's causing me this much grief hehehe Anyway, I'm looking for some more guidance if you can Thanks. -Original Message- From: Chong Yu Meng [mailto:[EMAIL PROTECTED] Sent: Saturday, June 07, 2003 7:19 AM To: Tomcat Users List Subject: Re: Help Please: Starting Tomcat using channelUnix with mod_jk2 Michael Cardon wrote: Where I am missing this?: undefined symbol: apr_md5_final My platform: RH Linux 8.0 You're missing the Apache Portable Runtime (APR).

tomcat on different server?
Here's a question: Using mod_jk2 with channel communication between apache2 and tomcat, can I map the [uri:] in workers2.properties to an instance of tomcat on a completly different server box??? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
JK2 - missing library
I'm trying to make the mod_jk2 connector under the following environment:
RH Linux 9
Apache= httpd-2.0.46
Java= j2sdk1.4.2
Tomcat= jakarta-tomcat-4.1.24
Connector= jakarta-tomcat-connectors-4.1.24-src

I run ./configure \

--with-java-home=${JAVA_HOME} \
--with-java-platform=2 \
--with-jni \
--with-pcre ... OK
I then run make and get one error:
cannot find -lpcre
Do I need to modify the Makefile somehow to get this to run? Any help is
very much appreciated. Thanks.

RE: JK2 apache2 log errors
Thanks for the info on the scoreboard Allen. Do you know if there is anyway to clear the scoreboard? -Original Message- From: Allen Williams [mailto:[EMAIL PROTECTED] Sent: Saturday, May 31, 2003 8:01 AM To: Tomcat Users List Subject: RE: JK2 apache2 log errors In the process of digging through the mod_jk2 source code to solve my own problem (which still hasn't happened), I came across extensive references to the scoreboard. It is a place in a workerEnv data structure that holds the process ID of a child process. I'm not sure about who spawns what where, but at least it appears Apache spawns off the jk2 stuff, which then goes off and spawns worker threads. It appears the scoreboard is a place in the worker environment to keep track of some of the housekeeping that goes on with these threads. I've only looked at it for about an hour, so this could be all wrong, but that's what it looks like.

Perhaps there is someone out there more familiar with it? Sorry! Scoreboard refers to the jkstatus context which, if you are using the default worker2.properties that came with the rpm package for mod_jk2, you will see a section on.
