The inprocess is for Apache to connect to Tomcat using JNI.  It currently 
only works for TC 3.3.x, so you can likely safely ignore it (or comment it 
out).

Re: workers.properties load balancing

[Steve Dodge]

Thanks for the answer.  In the future, I'm wondering if you know where I 
could find some debug output that will tell me my workers.properties was 
misconfigured.   The only output I was getting was through the 
mod_jk.log which told me JkMount was handling the request but could not 
find the worker.


Thanks,
Steve

Hi Steve,

not a bug in 1.2.6 either:

You have used the attribute balance_workers:

 


worker.router.balance_workers=worker1,worker2
   



Version 1.2.6 only knew about balanced_workers. See the tiny difference?
In 1.2.14 you can use either of both and balance_workers take precendence.

I have some clarification on my workers.properties issue.  It's not an
Issue!  The version of JK connectors was not JK 1.2.14, it was JK
1.2.6.  Sorry to leave anyone scratching their head.   I told my system
admin to build from source JK 1.2.14, but to save time he found a
pre-packaged rpm from RedHat containing JK 1.2.6.  I wasn't aware of the
fact that I had debugged version 6 instead of 14.  So for those who are
interested, JK 1.2.6 had BUGS.

-Building mod_jk 
On another note, compiling JK connectors went very smooth on a stock
redhat box with RPM devel packages.  All we had to do was install the
httpd-devel-2.0.52-12.2.ent.i386.rpm and any rpm's required by it (to
get a list type  rpm -qp --requires httpd-devel-2.0.52-12.2.ent.i386.rpm
)  Then download and extract the JK source code.  Navigate to the native
directory type in |*./configure --with-apxs=/usr/sbin/apxs, the

Final questions: workers.properties

[David Thielen]

Hi;

 

First off thanks to all for help - I think I'm just about done. Question:

 

workers.properties.minimal (which works fine) only has:

worker.list=ajp13w

worker.ajp13w.type=ajp13

worker.ajp13w.host=localhost

worker.ajp13w.port=8009

 

While workers.properties (not load balancing) also has:

workers.tomcat_home=/var/tomcat3

workers.java_home=/opt/IBMJava2-13

ps=/

worker.inprocess.* (lots of inprocess ones)

 

Are the above needed for anything? It wasn't clear to me reading the docs
what inprocess was for.

 

??? - thanks - dave

Re: workers.properties directives

mod_jk 1.2.14:

List of workers, attributes and defaults. ajp14 is not included.

global:

- worker.maintain (60)
[and some obvious others]

all workers:

- type (ajp13)

ajp12:

- host (localhost)
- port (8007)

ajp13:

- host (localhost)
- port (8009)
- connection_pool_size (1) [aka "cachesize" which is the old and
deprecated name]
- cache_timeout (0)
- socket_timeout (-1 = disabled)
- socket_buffer (8192)
- socket_keepalive (false)
- recycle_timeout (0)
- connect_timeout (0)
- reply_timeout (0)
- prepost_timeout (0)
- recovery_options (0)
- retries (3)

lb:

- balanced_workers / balance_workers
- sticky_session (1)
- sticky_session_force (0)
- method (0=BYREQUESTS)
- lock (O=OPTIMISTIC)
- recover_time (60, also mimimum 60)

per balanced worker:

- lbfactor (1)
- domain (NULL)
- redirect (NULL)
- disabled (0)

I hope this helps.

workers.properties directives

[Olaf Lautenschlaeger]

Hi all,

recently I stumbled over the mod_jk statusworker feature coming with
recent mod_jk versions and, of course, I immediately wanted to have
such neat thing :-)

Up to that time, I didn't saw an imperative need to have balanced wor-
kers (Apache+Tomcat on the same machine; one single ajp13 type
worker did his job fine for me so far).

Since it turned out that the status worker will talk to lb type workers
only, I simply renamed my existing ajp13 worker, then established
another lb type worker of the former name which itself "sits" now on
that ajp13 type (or "node") worker.

But here I'm asking myself: Where do I preferably apply those "more
sophisticated" settings like

worker.XY.recycle_timeout, worker.XY.cachesize or
worker.XY.cache_timeout ??

(seems that we can assign them both to lb type as to ajp13 type workers;
at least I didn't found anything that rules out doing so in the online
docs)

In other words, do they a better job when defined with worker "MyWorker"
or with "node1" in the following httpd.conf example (simplified view;
think yourself a "JkWorkerProperty" in front of all these "worker..."
directives):

worker.list=MyWorker
worker.MyWorker.type=lb
worker.MyWorker.balance_workers=node1
worker.node1.type=ajp13
worker.node1.host=localhost
worker.node1.port=8009


  JkMount MyWorker


??

Some of that worker.XY... options sound more "IP related", so I would
tend to assign them to ajp13 type workers;
on the other hand, worker.XY.cachesize seems to have more impact to
the endpoint software layer, which implies that it unfolds it's effect
better within the load balancer tier.

TIA

workers.properties: cache_timeout/socket_timeout/...

[Joseph Lam]

Anyone familiar with the tuning of the timeout settings?
cache_timeout
socket_timeout
recycle_timeout
prepost_timeout
connect_timeout
reply_timeout

There are so many timeout settings but the doc online is a bit confusing
to me. I don't know which value is used under different situations...

e.g.:  

When Apache create a new ajp connection to TC and forward a request, will
the socket_timeout or connect_timeout or prepost_timeout be used?(or a mix
of them?)

When an ajp connection is idled, will cache_timeout or recycle_timeout be
used?

Is socket_timeout always in effect together with each of the other
timeouts?

What if the page content from TC is lengthy and took longer than
cache/recycle_timeout? 

Regards,
Joseph

Sorry, I might have been a bit unclear.. I meant if mod_jk could read
updated workers.properties at runtime. We are using mod_jk2 now, and
it can do that.. I am interested in knowing if mod_jk can do the same
thing. E.g. adding more servers to the workers.properties while
apache2 is running, and that mod_jk discovers this.


If mod_jk can do this, I would rather use that one, since it is still
supported, which mod_jk2 is not.

The documenation recommends using mod_jk, since it is supported. It
also states that several of the improvements in mod_jk2 are backported
to mod_jk, but it fails to state which...

Nevermind (not that too many did mind :-) )
The graceful shutdown of server nodes is too complicated in mod_jk -
I'll take the gamble (as it is officially unsopported), and go for
mod_jk2...

mod_jk dynamic update of workers.properties

[Olve Hansen]

Haven't found docs about this anywher (i might be short sighted though).
Can mod_jk dynamically update the contents of workers.properties?
Or do I have to use  mod_jk2 to be able to do that..

Matt,

Sorry ignore my last mail. I tried to pin point the problem. But i could

[lb:lb_1]

Can any one explain better about this?

Thanks for helping. So You mean we can ignore completely workers.properties

workers2.properties is for the jk2 connector and workers.properties is for
the jk connector, they have slightly different syntax I think but you'd best
look up the jakarta site for that.

Hi,
Thanks for replying me!
Unfortunatly the HTTP call is the only way I have to submit my

Ideal would be to send a POST HTTP to tht URL with the same connection, I
mean 
the same socket where the HTTP service is up. The strange is that using a
php 
program, I can POST the HTTP using the same connection for all my requests. 
But I have to use the HTTP Servlet in stead of this php program. I believe

 is moot anyhow.
 
 Is it a requirement that you perform an HTTP call?  Could you get this

workers.properties question

[Simon Zeng]

Hi,

I have a question about workers.properties setting

In mod_jk.log, I have 
 JkMount /* loadbalancer

In workers.properties, I have

 worker.list = worker1, worker2, loadbalancer(1)

 #worker1 configuration
 #worker2 configuration

 #---Load balancer worker --
 worker.loadbalancer.type=lb
 worker.loadbalancer.balanced_workers = worker1, worker2  (2)

worker1 and worker2 are real tomcat instance. loadbalance is for dispatching
message to worker1 and worker2.

My question do I need worker1 and worker2 on line(1). Somewhere between
lines in tomcat HOWTO, I read those workers on line (2) are those not on
line(1). I tried both keep them on line(1) aand remove them from line(1) and
don't see any different result.

Could anyone please enlighten me which is the right way and where can I find
description on suchs issues?

Thanks,
-Simon

Basically you've to define the hosts in the server.xml as describes in the

in apache's httpd.conf (the virtual hosts in apache must have the same 
name as in tomcat) :

NameVirtualHost your_ip:80

If I recall it correctly...


thanks for the reply. I wasn't explicit when I was asking about the 
differences.

I need to know what the differences in the workers.properties file are 
regarding the virtual name hosts and whether each virtual host requires 
a separate worker.

If not so, how would I assign several virtual hosts to a worker?



you dont need to modify your workers.properties, the "default" will do
fine.
mod_jk passes the hostname as defined in the apache's virtualhost to 
tomcat.

workers.properties and virtual hosts

[Michael Kastner]

Hello,

I've searched the archives and docs, but so far haven't found any hints 
on this topic:

I am trying to install tomcat5 with apache 1.3 using the mod_jk connector.

On my test system I've got several virtual hosts. Do I have to create a 
separate worker for each virtual host?

E.g.:

worker.list= worker1, worker2, worker3

worker.worker1.type=ajp13
worker.worker1.host=host1.linuxstation2

workers.properties file - connecting Tomcat to Apache

[annimandary]

I'm trying to connect Tomcat and Apache. Initially, I didn't have the
workers.properties file and got the following error when I started Tomcat:

Can't find workers.properties at
C:\jakarta-tomcat\conf\jk\workers.properties
Please install it in the default location or  set the config location
Using 
Starting service Tomcat-Standalone
Apache Tomcat/4.0.2
Starting service Tomcat-Apache
Apache Tomcat/4.0.2


So, I created the workers.properties file and saved it as a CONF file. Is
that how it should be saved? I placed it in the folder jk but I'm still
getting the same error as before. Can anyone please advise?


Here is what's written in the server.xml file:

 


The workers.properties file is as follows:
# Define some properties
workers.apache_log=C:\Program Files\Apache Group\Apache\logs 
workers.tomcat_home=C:\jakarta-tomcat
workers.java_home=C:\j2sdk1.4.2

# Define 4 workers, 3 real workers using ajp12, ajp13, jni, the last one
being a loadbalancing worker
worker.list=worker1, worker2, worker3, worker4 

# Set properties for worker1 (ajp12)
worker.worker1.type=ajp12

worker.worker1.lbfactor=5 

# Set properties for worker2 (ajp13)

The workers.properties file has more to do with the connector that you 
use to hook Apache (or some other web server) to Tomcat than with the 
version of Tomcat itself.

Check the version of the mod_jk/mod_jk2/mod_webapp, etc. that you are 
using for an example.

Hey.

I've  solved the problem by using IP addresses instead of FQDNs in the

I had a similar problem today.  My workers file definitely existed but I kept

It turned out I had the JkWorkersFile directive defined inside a

Re: simple workers.properties question (John Turner's how-to)

[John Turner]

It just needs to equal "location of tomcat".  I used to think it had to 
match the ServerName...it doesn't.  It's merely a pointer to the machine 
that is running Tomcat.  If Apache and Tomcat are on the same machine, 
then "localhost" is fine.

RE: loadbalancer in workers.properties

[Turner, John]

That would be my guess.  Typically, machines are NEVER rebooted for
configuration changes (UNIX machines, at least).

My guess is you have a process that starts on boot that is binding to a port
ahead of what you think is actually happening.  

If the configuration files do not change, rebooting should have no effect,
as the only thing that changes is the network stack and the ports are reset.

I've an unusual problem : I got Apache collaborating with Tomcat on the
same box. Then I seperated the two and it worked. I rebooted the
machines, now Apache won't talk with Tomcat. I looked in log/error_log ,
it seems the Apache machine keeps trying to look for the examples in the
same box rather than in the Tomcat box. Apache won't find it there
because I haev renamed that directory...

Re: loadbalancer in workers.properties

[David Cassidy]

it's part of mod_jk

as I can assume that you have got mod_jk loaded and installed, working 
correctly
for one server I shall begin ...

In your workers.properties you will find an entry titled
worker.list

this will probably look like
worker.list=ajp13

You will then find the definition of ajp13 looking something like ...
worker.ajp13.port=8009
worker.ajp13.host=localhost
worker.ajp13.type=ajp13
worker.ajp13.lbfactor=1

The section of loadbalancer will look like ...
worker.loadbalancer.type=lb
worker.loadbalancer.balanced_workers=ajp13, ajp12

Now... Let us assume that you have 3 servers and they are all the same 
spec.
So you want to balance the load evenly..
( I am also assuming that you only have one apache server.)

ie your machines looks like :

+--+
|Apache|
+--+
|
++-+
|| |
+-+   +-+   +-+
| TC1 |   | TC2 |   | TC3 |
+-+   +-+   +-+

You need to define entries for your 3 tomcat servers...
( change the IP's to match yours..)

worker.TC1.port=8009
worker.TC1.host=192.168.10.1
worker.TC1.type=ajp13
worker.TC1.lbfactor=1

worker.TC2.port=8009
worker.TC2.host=192.168.10.2
worker.TC2.type=ajp13
worker.TC2.lbfactor=1

worker.TC3.port=8009
worker.TC3.host=192.168.10.3
worker.TC3.type=ajp13
worker.TC3.lbfactor=1

change these to match the above :

worker.loadbalancer.balanced_workers=TC1,TC2,TC3
worker.list=loadbalancer


And Bingo you have a working loadbalanced trio of Tomcat servers.

If you have 3 apache servers  ie like

+-+   +-+   +-+
| A 1 |   | A 2 |   | A 3 |
+-+   +-+   +-+
|| |
++-+
 |
 |
++-+
|| |
+-+   +-+   +-+
| TC1 |   | TC2 |   | TC3 |
+-+   +-+   +-+

you just need to setup the same workers.properties on all the apache 
servers...

Hope this helps

David

loadbalancer in workers.properties

[achana]

Hi All.
The doco's suggested that I can have 1,2 or more Tomcats running
(ideally one on each box).
The scripts for httpd.conf suggested a piece if s/w called "loadbalancer
eg.
...
DocumentRoot "/var/www/html"
...
JkMount /*.jsp loadbalancer
JkMount /servlet/* loadbalancer
***
etc

Where can I download this "loadbalancer" ?

 To all Tomcat users,

 I set LD_LIBRARY_PATH as the environment variable (export
LD_LIBRARY_PATH=/usr/lib)inside my Linux machine, and tried to access the
".so" file in "/usr/lib" directory from Java class file in Tomcat. But it
seem like Tomcat cannot locate the directory.

 From "Tomcat-Workers-HowTo.html" -
http://jakarta.apache.org/tomcat/tomcat-3.2-doc/Tomcat-Workers-HowTo.html,
how can I set additional dynamic libraries path inside "workers.properties"?

 Something like this -> worker.inprocess.ld_path=/usr/lib ??

 Or is there any other extra configuration file that I need to edit as well?

 Regards,
 Johnny.

Thank you very much,

I've downloaded "jakarta-tomcat-connectors...src.tar.gz" and now I'll try to

(first I'll read all the documentation I've found in the "jk/doc" subdiretory)

Thanks again.

AFAIK workers.properties is not create automically.
Simply copy exist file from

# jakarta-tomcat-connectors-4.0.2-01-src/jk/conf/workers.properties

or i miss something.

Where is workers.properties???

[Luca Zancan]

Hi everybody,

I'm an absolute beginner with Tomcat and I'm installing Tomcat 4.0.3 on
a Linux RedHat 7.2  (kernel 2.4.7-10).
I'm trying to use AJP connector 1.3 to make Tomcat work with Apache
1.3.24.

Tomcat works great in standalone mode: no problems (Ive tested with
http:/192.168.254.1:8080)

Now I'd like to integrate Tomcat with Apache.

I've inserted the following directives in the "server.xml" file:

under "
and a similar Listener directive under "

and indeed this have created 2 directories under $CATALINA_HOME/conf,
called "auto" and "jk".
In $CATALINA_HOME/conf/auto I find the file mod_jk.conf (correct: I'll
use it in an include statement in my httpd.conf later...)
But the $CATALINA_HOME/conf/jk directory is empty.

My question is: where is the workers.properties file???
Is it not generated automatically???

I've downloaded a binary version of mod_jk (mod_jk-01.so) and therefore
I've not compiled it: I've simply copied it in
/usr/local/apache/libexec/mod_jk.so...

Probably I'm missing something...

Thank you very much for your help.

Bye,
Luca

Mod_jk not finding workers.properties

[Ryan McDonough]

I'm trying to get mod_jk configured on both Mac OS X and Solaris 8. Both
systems are running Apache 1.3.23 and Tomcat 4.0.3. I have built mod_jk from
the sources found in the jakarta-tomcat-connectors package and the build
went smoothly on both systems. I have configured Tomcat to auto generat the
mod_jk.conf file and that too appears fine. The problem I am having involves
Apache. Each time I try to start Apache, with mod_jk enabled, the server
will not start and I find this message in the error:

[Wed Jun 12 14:27:40 2002] [emerg] (2)No such file or directory: Error while
opening the workers

I do have a workers.properties file in Tomcats conf directory. I have double
check everything from permissions to making sure the file is named correctly
and I still get the same error on both systems. Any ideas?

Re: Mod_jk not finding workers.properties

Yup, already had that in there and and the path to the workers.propeties
file is correct in both cases. That¹s what's weird about the whole thing.
Any other thoughts?

Your mod_jk configuration (either in or included in your httpd.conf) 
specifies the location of the workers.properties file.

workers.properties configuration

[Ronnie T Livingston]

Hi, Im trying to setup a test load balanced configuration consisting of 3
machines.  Ive read Mr.Forget's tutorial but I couldnt really follow at a
certain point (modifying the server.xml) since i am using an older version
of tomcat.

Ive also read the Tomcat Workers how-to and im a little confused.  Do we
create this configuration on all the tomcat servers?  Once we configure
the workers.properties is there any other files needed to configure or
should it start balancing?

If anyone knows of any other tutorials or guides to using
workers.properties for load balancing I would be very much appreciative.

I am using Apache 1.3.19 and Tomcat 3.2.3

thanks,
Ronnie

I'm not sure... :) I only just got it working, so I'm still testing it.

Every time an endpoint to a tomcat is requested I stat the
workers.properties file, if it has changed, the load-balancer
reconfigures itself. The reconfiguration does cause a small delay
response to any incoming requests as mod_jk has to open a new socket to
the desired tomcat.

Put it this way, I think it is quicker to reload the load-balanced
workers than to do a graceful apache restart. It is also cool to edit
the properties file, save it, and watch an immediate change in the
results coming to the script hammering your website... :)

I'm thinking about adding a minimum time between stats on the
workers.properties file. :)

Note: Currently the code only supports reconfiguring workers that are
under a load-balancer.

I guess this functionality is only required if you are frequently changing
the workers.properties file for some reason.

Anyone got any other ideas/requests and more importantly advice?

Jonathan.

mod_jk: Auto reloading workers.properties file.

[jonathan]

Hi all,

I've written a small patch for mod_jk that automaticly reloads the
workers.properties file when ever it is changed.

Currently it only works with apache-1.3 but it trivial to make it work
with the others.

Is anyone interested in using this patch?

Nothing.  I verified your assumptions and you are right.
I created a worker.properties file which does not contain
worker.tomcat_home or worker.java_home and I placed it
under /usr/local/apache/conf.  And it works.

See: http://www.ubeans.com/tomcat

RE: worker.tomcat_home etc in mod_jk's workers.properties

[Larry Isaacs]

worker.tomcat_home is not used with the mod_jk connector.
However, the IIS and Netscape connectors are mod_jk based and
allow Tomcat to be run in-process.  It is for the in-process
worker that this setting is used.

worker.tomcat_home etc in mod_jk's workers.properties

[John Holman]

Can anyone explain the purpose of the worker.tomcat_home,  worker.java_home 
and ps entries in mod_jk's workers.properties file?

My understanding is that workers.properties is used only to configure the 
mod_jk webserver plugin, and I'm at a loss to see why that would need to
know anything about Tomcat or Java. (Anything that Tomcat needs to know 
should surely be specified in the server.xml configuration file anyway).

Indeed when mod_jk is deployed on a system without either Java or Tomcat 
installed (because these are running on a different host) these entries are 
meaningless - and things seem to work OK if you just miss them out.

What am I missing?

Thanks, John.

RE: jkconf? Does it work in 4.0.1? Where's workers.properties?

[Larry Isaacs]

There is are some examples of the file contents which
may be found at:

<http://jakarta.apache.org/tomcat/tomcat-3.3-doc/mod_jk-howto.html#s9>

Bill Barker has ported the ApacheConfig to jakarta-tomcat-connectors,
so some configuration file generation should be available in the
next release of Tomcat 4.x.  I don't know how much documentation
will be available at that time.

jkconf? Does it work in 4.0.1? Where's workers.properties?

[Scott Merritt]

Hmm... My next question is, how come I can't find a workers.properties file?

I'm using Tomcat 4.0.1 and trying to get it to autgen the config files...
None of these generate anything:
./startup.sh jkconf
./catalina.sh jkconf

Okay...  So I figured I'd do it manually, but I don't see any
workers.properties file to follow the "simple" example in the 3.3 mod_jk
docs (http://jakarta.apache.org/tomcat/tomcat-3.3-doc/mod_jk-howto.html)

Hmm...  Now what?  Confused.  Does Tomcat 4 not do this conf writing
anymore?

Load balancing entry in workers.properties

[Shahed A Moolji]

 
Hi,

I am NOT using load balancing features of TC 3.2.3
w/Apache / mod_jk.

But I have an entry in the workers.properties that defines
a load balancer thread like 
lb=ajp12,ajp13

I am not using JKMount  lb anywhere.

I just have JKMount  ajp13 in httpd.conf.

Will this extra entry in workers.properties create any overhead ?

Thanks
Shahed.

Re: workers.properties Configuration??

[Scott Tatum]

You don't have to configure it if you are running Tomcat standalone, but
you do have to configure it if you are running Tomcat with Apache. I am not
familiar with other webservers that Tomcat can connect with.

[Brenda Mijares]

I heard somewhere that is you have tomcat on a unix box you do NOT need
to configure the workers.properties file 

Has anyone else heard this or read this??

Has anyone configured a jni worker in the workers.properties file??

Different ports for ajp in workers.properties and server.xml

[guyr]

I'm experimenting 
with the ajp12 and ajp13 connectors.  There is a port setting for each of 
these in both workers.properties and server.xml.  What does it mean if I 
assign one port to (e.g.) ajp12 in workers.properties but give the ajp12 
connector a different port number in server.xml?

mod_jserv vs. mod_jk (configuration questions for workers.properties)

[Max Clark]

I have been browsing through the documentation and have hit a wall. I want
to run Apache and Tomcat on separate machines. More than that I want to load
balance my Tomcat application servers. I have done this in the past using
mod_jserv to talk to jserv servers and it worked pretty well.

>From what I have gathered I want to use mod_jk with ajp v1.3. I understand
everything in the mod_jk.conf-auto and the workers.properties except... the
workers.properties file defines tomcat specific variables (i.e.
workers.tomcat_home, workers.java_home, classpaths etc...). How can I define
tomcat internals from an apache machine that doesn't have tomcat installed?
What do I need to define within the workers.properties to have my apache
machines connect to the tomcat machines.

Do I have to install tomcat on all of the machines? What about a jdk? Has
anybody done this? Can somebody help me with this config?

Thanks in advance,

-Max

Re: workers.properties etc.

[Dave Smith]

Ralph,

worker.inprocess refers to the type of deployment
where tomcat is going to run in the webserver process.
Defacto, this applies to the Win32 scenario, not a
unix box where tomcat will run on it's own pid.
So (unless I am mistaken) this is a non-issue in your case.

There is actually quite a bit of documentation available,
but you need to d/l the src disto and read everything in
the docs folder, read server.xml comments in conf, and
finally look in the source folders for some "hidden" docs.
Confusing? Sure, but everything you are asking about is
in there.

> I'd also appreciate some more information concerning the interaction of

The source code for them all is available.

Regards,

Dave

Re: workers.properties etc.

[Pete Ehli]

If the docs are confusing I agree, but the example given in Working with
mod_jk for the worker.properties file is for Solaris and I sure the
directory structure is very similar in Linux. The examples provided in
tomcat is a great way to see where to place your servlets and JSP pages,
also how to set up your web.xml file and set your server.xml. The only
difference when using Apache is you want Apache to serve your static content
which should be easy.

workers.properties etc.

[Ralph Jensen]

Is there any documentation concerning the settings in workers.properties?
The defaults which come with it are apparently for Windows but I'm using
Linux.

In particular:
worker.inprocess.jvm_lib is set to some jvm.dll. Should that be set to the
java wrapper JAVA_HOME/jre/bin/java ?

I'd also appreciate some more information concerning the interaction of
server.xml, mod_jk.conf and worker.properties. I've read through 'Working
with mod_jk', 'Tomcat workers.properties' and the minimalistic Tomcat users
guide but I'm still a bit confused where to put my servlets and how to load
them from HTML - especially the use of 'servlet' and 'servlets'.

Tomcat3.1 & workers.properties file

Hi!

I think my previous mail was not sent out so here goes:

I am trying to set up load balancin between 2 tomcat servers. Just some simple 
questions:

Does the workers file works on tomcat 3.1 with mod_jserv?  I am runnin Redhat 6.2.  If 
it does, can you guys send me a copy of your worker.properties file? I tried usin the 
tomcat 3.2 workers file but couldnt get it workin.

Is there other configuration that I have to make other than the workers file?

Thanks a mil!
Samo

Tomcat 3.1 & workers.properties file

[Samo Kwee]

Hi,

Just some straight-forward question.

Does workers.properties file work under Tomcat 3.1 with mod_jserv?

If it does, anyone out there can send me a sample file?  I am using Redhat 6.2 with 
apache 1.3.14.

I have been tryin to get this work but seems like gettin nowhere close.  Pls help.

Thanks a mil!

RE: workers.properties & virtual hosts

[Stubenrauch,Andreas]

1.) The host in worker.properties is the host tomcat is running on (that's
not related to the the apache host. You can run tomcat on a different
machine than apache)

2.) You seem to have configured your mod_jk-Mounts yourself so you don't
have to bother with mod_jk.conf-auto. It's an auto-generated example ans
doesn't take all configuration into account.

3-5.) Your approach is almost correct, but if you want them running in
different JVMs you have to run multiple Tomcat-instances. So don't configure
your different ports in one server.xml but install and run tomcat multiple
times and with their own server.xml each.

/path/tomcat1/conf/server.xml (in there: port=8110)
/path/tomcat2/conf/server.xml (in there: port=8111)
...

$ /path/tomcat1/bin/startup.sh
$ /path/tomcat2/bin/startup.sh
...

workers.properties & virtual hosts

[Dominique BATARD]

Tomcat 3.2b6, Apache 1.3.14, NT 4

I'm running 3 virtual hosts and want to have each one his own JVM

In server.xml :
 ...
 ...
 ...
...
   
  ServerName host1
  
  JkMount /*.jsp ajp-8110
  JkMount /servlet/* ajp-8110

  Idem for host2  ajp-8111 and host3 ... ajp8112

My question is :
1 - the worker's host property must be localhost or the vhost server name ?
 If I use the vhost server name, apache complains and doesn't start

2 - I don't see any trace of ajp-8110, ajp-8111, ajp-8112 in
mod_jk.conf-auto

3 - In NT task manager, I see only 1 JVM working

4 - In jvm.stderr, I see the ContextManager: Adding context for my vhosts
thePoolTcpConnector : Starting of  my Ajp12ConnectionHandler for my 4
ports,
but after stopping tomcat, I don't seeany stopping of the 4 ports, and I
don't see the ContextManager: Removing context of the third vhost (host3).

5 - In workers.properties :
  worker.loadbalancer.type=lb
  worker.loadbalancer.balanced_workers=ajp12, ajp13
  The doc says the load balanced workers must NOT appear in the
worker.list , but they do appear here !

Any idea ?
