Re: Apache AJP to 4 TCs
I did a fresh install, and it all worked. Steps documented @ http://bruniglobal.blogspot.com/2010/09/load-balancing-4-tomcats-with-apache-22.html I then went back to my old install, and noticed that I didnt specific ServerName domain:80 I did that and it all worked.. weird. Anyway, thank you all for your help on this, I really liked Mark's worker.template approach :) and Chris' questions info. If there is anything I can improve in the process, as documented, please let me know.

Hi Mark Chris,
Thank you for the responses. I have gone about and installed a fresh Apache

So far so good. I can load balance across all 4 tomcats, BUT I HAVE NOT
ENABLED/ADDED SSL yet.
Could the the ssl config be causing me grief?

Re: Tomcat Load Balancing Not working and Apache URL is giving 500 error
Hi Amol, I am trying to do the exact same thing. It works for two workers, but fails as soon as I add one worker. Can you please try these alternatives, and let me know if it works for you? worker.loadbalancer.balanced_workers=tomcat1,tomcat2 worker.loadbalancer.balanced_workers=tomcat1,tomcat3 worker.loadbalancer.balanced_workers=tomcat2,tomcat3 For me, as long as I have two workers, it works. It would be interesting if its the same for you? I also came across these links which I am reviewing.

Re: Apache AJP to 4 TCs
With 2 workers, the system has been working well for months. I now wanted to add an extra two workers, i.e. a total of 4 tomcats, and load balance across all 4. Is this possible?

Re: Procrun problems with Tomcat 6 on Windows 64-bit
Hi Kevin, Personally I do not use the w.exe gui. I manage all tomcats via Services, and update the service.bat file if any registry/config settings etc need to be changed, so that we can manage changes/roll backs via SVN. This also makes it simpler since we have many TCs on same OS. So, I recommend you download the .ZIP version, and install the service using services.bat I also rename the tomcat6 to whatever service name I need, so that I can install multiple tomcats on the same server OS. Via the services.bat you can also change the logging path, jvm, set threads size, memory, etc. e.g. of our services.bat if this helps you out. @echo off if %OS% == Windows_NT setlocal rem --- rem $Id: service.bat 908749 2010-02-10 23:26:42Z markt $ rem --- rem Guess CATALINA_HOME if not defined set CURRENT_DIR=%cd% if not %CATALINA_HOME% == goto gotHome set CATALINA_HOME=%cd% if exist %CATALINA_HOME%\bin\Secure02Web64.exe goto okHome rem CD to the upper dir cd .. set CATALINA_HOME=%cd% :gotHome if exist %CATALINA_HOME%\bin\Secure02Web64.exe goto okHome echo The tomcat.exe was not found... echo The CATALINA_HOME environment variable is not defined correctly. echo This environment variable is needed to run this program goto end rem Make sure prerequisite environment variables are set, we added specific JAVA_HOME64 path rem typically, JAVA_HOME64=C:\Program Files\Java\jdk1.6.0_17 - NOTE WE USE the JDK so we use server mode if not %JAVA_HOME64% == goto okHome echo The JAVA_HOME64 environment variable is not defined echo This environment variable is needed to run this program goto end :okHome if not %CATALINA_BASE% == goto gotBase set CATALINA_BASE=%CATALINA_HOME% :gotBase set EXECUTABLE=%CATALINA_HOME%\bin\Secure02Web64.exe rem Set default Service name set SERVICE_NAME=Secure02Web64 set PR_DISPLAYNAME=Secure02Web64 if %1 == goto displayUsage if %2 == goto setServiceName set SERVICE_NAME=%2 set PR_DISPLAYNAME=Secure02Web64 %2 :setServiceName if %1 == install goto doInstall if %1 == remove goto doRemove if %1 == uninstall goto doRemove echo Unknown parameter %1 :displayUsage echo. echo Usage: service.bat install/remove [service_name] goto end :doRemove rem Remove the service %EXECUTABLE% //DS//%SERVICE_NAME% echo The service '%SERVICE_NAME%' has been removed goto end :doInstall rem Install the service echo Installing the service '%SERVICE_NAME%' ... echo Using CATALINA_HOME:%CATALINA_HOME% echo Using CATALINA_BASE:%CATALINA_BASE% echo Using JAVA_HOME64:%JAVA_HOME64% rem Use the environment variables as an example rem Each command line option is prefixed with PR_ set PR_DESCRIPTION=Secure Web 02 TC 6.0.28 set PR_INSTALL=%EXECUTABLE% set PR_LOGPATH=%CATALINA_BASE%\logs set PR_CLASSPATH=%CATALINA_BASE%\bin\tomcat-juli.jar;%CATALINA_HOME%\bin\bootstrap.jar rem Set the server jvm from JAVA_HOME64 set PR_JVM=%JAVA_HOME64%\jre\bin\server\jvm.dll if exist %PR_JVM% goto foundJvm rem Set the client jvm from JAVA_HOME64 set PR_JVM=%JAVA_HOME64%\jre\bin\client\jvm.dll if exist %PR_JVM% goto foundJvm set PR_JVM=auto :foundJvm echo Using JVM: %PR_JVM% %EXECUTABLE% //IS//%SERVICE_NAME% --StartClass org.apache.catalina.startup.Bootstrap --StopClass org.apache.catalina.startup.Bootstrap --StartParams start --StopParams stop if not errorlevel 1 goto installed echo Failed installing '%SERVICE_NAME%' service goto end :installed rem Clear the environment variables.

Re: Tomcat 6 64 bits, Java 6 64 bits and -Djava.library.path
Everything can be set up via service.bat You should modify this file only. This way when you install the service or remove the service, it works gracefully, and all libs, memory requirements, etc. are recorded in the registry.

Yes, that's true. You can also use the GUI. Personally, I like the script, because it can be committed to repository(SVN, etc), and its easier to replicate and maintain.

Re: question for sso session replication in tomcat 6.0.26
Looking at the code I think this is wrong
if (!_ssoSessionId.contains(. + jvmRoute)) {
_ssoSessionId += . + jvmRoute;
response.addCookie(new Cookie(_SSO_SESSION_COOKIE_NAME, _ssoSessionId));
}
The original sessionId will already have the .+_any_other_jvmRoute
included, so you need to substring it, and append the new jvmRoute.
_ssoSessionId= _ssoSessionId.substring(0, _ssoSessionId.indexOf(.))
and then add
_ssoSessionId += . + jvmRoute;

Hi experts
I found this old email from archive in TC 5.5.23.
Does this problem still exist in tomcat 6.0.x or 6.0.26?
When failover occurs, sso session id is updated with new number after
forcing a user to relogin to the application since sso session id is not
replicated and rewritten correctly. Could someone explain what is
expected in current tomcat 6.0.x cluster upon failover? Should sso
session id is replicated correctly in tomcat 6.0.x?

can launch embedded apps which use the SSO cookie to access other
webapps on
the server (Single-Sign-On for the user).
Things are working perfectly for the normal cookie but not for the sso
cookie.
The problem I have is that tomcat does not replicate SSO sessions so
when these embedded apps route through the load balancer we get 401s on
all the other cluster members except the one which actually generated
the SSO cookie.
I wanted to know if we can edit the SSO cookie generated by tomcat to
also
contain the jvmRoute parameter so that the load balancer directly goes
to the
correct cluster member.
I tried doing this in my code by fetching the SSO cookie and appending
to it
the jvmRoute as follows :
HttpServletRequest request =
(HttpServletRequest)Security.getContext(HttpServletRequest.class);
HttpServletResponse response =
(HttpServletResponse)Security.getContext(HttpServletResponse.class);
if(request != null) {
String jvmRoute = Vinod_Cluster_1; // as mentioned in
server.xml
Cookie[] cookies = request.getCookies();
for(int nc=0; cookies != null nc cookies.length; nc++)
{
if(_SESSION_COOKIE_NAME.equals(cookies[nc].getName())) {
_sessionId = cookies[nc].getValue();
}
else if(_SSO_SESSION_COOKIE_NAME.equals(cookies[nc].getName())) {
_ssoSessionId = cookies[nc].getValue();
if (!_ssoSessionId.contains(. + jvmRoute)) {
_ssoSessionId += . + jvmRoute;
response.addCookie(new Cookie(_SSO_SESSION_COOKIE_NAME, _ssoSessionId));
}
}
But after this I started getting 401s from even the correct cluster
member. My guess is addCookie doesnt update the cookie in tomcat's cache
which is reasonable.
Other thought was to edit tomcat's sso cookie generation code to append
the
jvmRoute to the sso cookie.
Is there an better way to achieve this in my code base ?

Re: question for sso session replication in tomcat 6.0.26
Hi Yasushi
In your serverl.xml have you added the jvmroute to the Engine?
i.e.

Looking at the code I think this is wrong

The original sessionId will already have the .+_any_other_jvmRoute

_ssoSessionId= _ssoSessionId.substring(0, _ssoSessionId.indexOf(.))

Re: redirect some requests to another tomcat.
This is pretty much what I have been working on. As a few hints, you'll need Apache in front, and setup AJP on tomcat. I have set up loadbalancing, and have the two tomcats doing session sharing, and use the jvmroute to route to respected tomcat. You might need to change your server webapp java code so that you know which tomcat to jvmroute to. Basically, with the loadbalancer,it can randomly pick any tomcat. When the user logs in, I have some business logic to detect whether they should be on current web app. if they are not, I save session details, and then I redirect to url again, but append the jsessionid=SESSIONID.worker2 to url, and Apache knows from that to automatically use worker2. (assuming worker2 is the tomcat web app user is supposed to be on). The only thing I am worried about is race conditions with session replication. The worst that can happen is that the user will need to log in again, if the session hasnt replicated in time. The other option I am looking at is to redirect to different contexts from a generic login page... but I havent worked out how I can set Apache up to map many different contexts to one. Google Apps seems to do this. See http://www.google.com/a and then Click on Sign in here, and enter a e.g. domain, ziateresa.com It redirects to a new context. /AB On Tue, Jun 15, 2010 at 5:50 PM, kiran surapaneni svkir...@gmail.com wrote: Hi, I have several applications running on my tomcat server.

AJP java client
Hello all, I have a situation where I wish to break up my web application, but wish to maintain the same domain as the front end URL. All customers log in via a single domain using their email address as a username. The email address gives them access to their customer repository data (lucene, etc), which is only accessible by that customer account. I would like to split the web app up, so that the front end server has smarts to know which backend tomcat server to redirect to. As far as I know, Apache AJP can be configured to redirect to different tomcat backend servers by implementing rules, ideally URL based. But for me, the URL is always the same. So, I was wondering if there was a way to code an AJP client inside a front end tomcat server, so that I could redirect to whatever backend server the business rules decided. 1. Login Screen on front end server 2. User attempts to log in, verify against DB, and then work out which back end tomcat server to AJP to. 3. All traffic goes via front server one to the decided backend server 2. any other ideas are also welcome Thanks Andrew

If I used the jSession idea, I am assuiming I could filter apache on . + jvmRoute ... right? and redirect to relevant AJP/Tomcat.

As far as I know, Apache AJP can be configured to redirect to different tomcat backend servers by implementing rules, ideally URL based. But for me, the URL is always the same. So, I was wondering if there was a way to code an AJP client inside a front end tomcat server, so that I could redirect to whatever backend server the business rules decided. You can force Apache httpd to direct a request to a particular backend Tomcat server by putting a specially-crafted jsessionid into the URL. If you don't use cookies to track the session for these requests, you should be able to create a URL like this: URL + ;jsessionid= + sessionId + . + jvmRoute + ? + queryString Would something like this work for you? - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkuzV/kACgkQ9CaO5/Lv0PBfPQCgutR+7yGVAYI3MbKkMM1u5Rlp KzUAnjojlVj4Z6rJinYPVvQ1OV4590Ar =qOiH -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
