Re: mod_jk2 and stickySession
Good evening Christian. Have you set the jvmRoute parameter in each Tomcat, and the TomcatID (aka route) for each JK worker?

Re: jk2_init Error ??
I'll take the 'scoreboard' question... It's the shared memory area for mod_jk2... it facilitates the creation the /jkstatus page it is also saved to disk and is represented in workers2.properties under the [shm] section, with details such as shm file path+name and file size attributes. I think if you did a text search for 'scoreboard' in the Tomcat docs there might be a bit more information.

So round robin code is broken with current mod_jk1/2 and prefork Apache (1.3.27 and default Apache 2 configuration) Unfortunately you can't use Apache 2 everywhere, i think it doesn't compile with worer mpm on solaris for example. To install Apache 2 with worker mpm you need to build it from source and use the following configure: ./configure --with-mpm=worker ... This should be fixed so Apache 1 users get a working round robin too. Although i don't know much about the mod_jk(2) code, I agree to Bill, this should be a relatively easy fix.

Besides the behaviour of sticky_session off should be theoretically similar as when any new user logs on to the server and hasn't established a session yet, right? The mod_jk lb_factor and lb_value also seem to do pretty nothing (on prefork Apache): - Tested low lb_factor on first Tomcat and increased lb_factor on following Tomcats, last Tomcats with higher lb_factor still got no requests - lb_value is almost always the same as lb_factor in JK2's jkstatus page when you access the application the lb_value changes to exactly twice as the lb_factor (on first Tomcat mostly) and then goes down to value of lb_factor again (before request: lb_factor 100, lb_value 100 after request: lb_factor 100, lb_value 200 a bit later: lb_factor 100, lb_value 100 again) How the Load Balanciung of mod_jk could be enhanced to be a real load balancing, not just round robin: Have some rules regarding the Status/Load of Tomcat/JVM, which you can put in any order you prefer (mod_backhand does sth. similar) (those will propably need jni or sth. else to work): - byJVMThreads - byJVMMemoryUsage - byJVMCPUUsage - byRoundRobin (and one which actually works ;-) etc. We considered alternative methods for load balancing too, but they all have some other downsides, so the best thing would still be if mod_jk round robin works as its supposed to be: - DNS Round Robin or Apache mod_rewrite Round Robin (similar sub-URLs for one app on same server - saves you from buying several SSL certificates) Problems: - Bookmarks - No real load balancing (ok mod_jk doesn't seem to have this either) - Requests go to down Tomcats also, no failover - Apache Loadbalancing with mod_backhand Nice approach of several Load Balancing decision rules (byCPU, byApacheChilds, byRandom etc.), which the user can put in any order he likes See http://www.backhand.org/mod_backhand/FAQ.shtml#question7 Problems: - HTTPS Apache in Front with mod_backhand using Proxy Connections to connect to Apache/Tomcats in back causes problems because of URL Redirects from Tomcat/Java - Requests go to down Tomcats also, no failover - Not sure if keeping Sessions works (backhand could use JSESSIONID for sticky sessions, have yet to test that) - Hardware Load Balancer (dind't investigate much on that) Problems: - IP based, read sth. that this ain't a particular good solution too mod_jk Tomcat Users List [EMAIL PROTECTED] schrieb am 15.07.03 07:45:11: This is a pretty good description of what goes on, and it results in the highly skewed distributions that you are seeing.

Good morning Simon. 'RoundRobin' is less likely the more Tomcat's you add I suspect. The balanced worker program always searches for a new worker by starting pointers from 1 rather than the last successful worker used, (AFAICT), and if a worker is free for the task it makes for muddy water indeed if you bypass it in the hope of finding something better... You need to remember which one was used 'last', which is a 'state' not remembered if/once session ID's are used (which go to the worker that handled it the last time). If you think about 'balancing' it is 'mindgame' to decide how a 'load' might be distributed... based on session counts? based on request handling time? and what 'integration' period would you use? ... and then there are preferences based on load, server grunt, network traffic, background tasks... at the end of the day, the idea is to handle user requests, so if they're getting processed in a 'timely' manner perhaps you can put the 'unused' Tomcat's behind another Apache? ... or start a new thread here on how balancing might be better handled in different situations... Another 'possible' might be to add more balance workers and split your url's to these, in turn connected to more ajp13 workers using some of the Tomcat's currently sitting idle.

Windows, Mod_Jk2, SHM and Load Balancing.
Good morning all. Trying to get loadbalancing working on a WinNT box with mod_jk2 to two separated Tomcats. - Setup is Apache 2.0.46 + latest cvs mod_jk2 on WinNT; - /jkstatus page works but reports 'no shm'. The shm memory file is created and 1MB+, all 0x00; - General log entries indicate the lb:lb worker can't find a worker available. (I get back a custom NoWorkerMsg, although the 503 code is not to be seen); - The TomcatID's on the two workers are set uniquely and match the jvmRoute set in their respective Tomcat's; - Both workers are in group=lb:lb; - The lb:lb has workers=worker1,worker2; - The uri's are aimed at lb:lb. A search of Apache on Google suggests this config doesn't come up often. Any insight appreciated. TIA. Signed, Aching head, Norm

Re: Problems with mod_jk2
Good morning Eric.
The setting format for 'config.file' at least confirms what a trowel through
the source code turned up. Thanks.
The 'TomcatID' parameter is also alternately named 'route' in mod_jk2, and
is, I think, used mostly in load-balance situations, where, at the Tomcat
end, it is called 'jvmRoute' on the Engine element.
The port and address are not 'normally' needed as mod_jk2 will also use the
channel.socket name elements [channel.socket:host:port] for these
parameters... (which is not entirely kosher in my view). Hence the clearest
method would be to include both the port= and host= parameters under the
[channel.socket:.] section.
I _think_ this helps.

JkSet config.file /path/to/apache/conf/workers2.properties

You can also use tomcatId instead of calling out the host and the port.
Then use the jk2.properties file that comes with tomcat. This is the one
that has everything commented out. You don't need it because apache is

Use the default Connector entry in server.xml for the Coyote/JK2
connector.
This creates a simple single worker, non-loadbalanced connection. You can
look at the example workers2.properties that comes with the connectors
source and get an idea how to do loadbalancing. But basically you create
loadbalancing workers and add workers to the load balancer group. Then
you map the URI to the loadbalancer group and it uses the workers you
defined in that have in that group to connect to Tomcat.
At least that's what I have been working with. Seems to work.

Re: Problems with mod_jk2
Good morning again.
Tomcat supports having multiple ServiceEngine entries within the
Server.xml, and each one would need to be identifiable when a single
Apache/jk(2) setup is forwarding requests to the one Tomcat.
The [channel.socket:...] identifies where/how to get from mod_jk(2) to the
Tomcat machine (ie host/port), but the actual workers need to be able to
identify either:
- which ServiceEngine entry to aim at on a given machine OR
- mod_jk(2) needs to be able to tag which worker processed a request so that
the session goes back to the same worker.
G'day,
Ya. You are right. I think tomcatId is just something tomcat uses to
internally to keep track of the workers. It could be anything such as
tomcatId=worker1:8009
but you really define the host and the port in the [channel...] section as
you mention. You could have multiple workers pointed at the same host on
the same port. The only way to tell them appart is by the tomcatId. (I
think).
There is a little bit of difference between the configs if you run tomcat
and apache on the same box or if they are two seperate boxes. I think
that is the most confusing part/lack of docs.
The major difference is that [channel.socket:..] points port= to 'localhost'
(ie 'this machine') if Tomcat is on the same machine as mod_jk(2) or to an
actual ip or domain name name if Tomcat is running on another machine.
Some packet probing might resolve this.
For now,
Norm

Use the default Connector entry in server.xml for the Coyote/JK2
connector.
This creates a simple single worker, non-loadbalanced connection. You
can
look at the example workers2.properties that comes with the connectors
source and get an idea how to do loadbalancing. But basically you
create
loadbalancing workers and add workers to the load balancer group. The
n
you map the URI to the loadbalancer group and it uses the workers you
defined in that have in that group to connect to Tomcat.
At least that's what I have been working with. Seems to work.

Re: JK2 config
Good evening Nikola. Best of luck and I will watch your 'thread' with interest. I asked some technical questions about mod_jk2 a few weeks ago and got deafened by the silence. Considering a predominance of questions here are about configuration issues, it is amazing there seems to be enough time to answer the questions (most anyway) and yet not enough time to get the docs up to scratch and reduce the 'clutter' here. Depending on your skills, sometimes wading through the source code can reveal needed things of use. Another method would be to write up a list of specific things you want to know rather than seek the 'grail' of comprehensive mod_jk2 documentation. (The module itself is still 'under construction' and the manual is developed from that.) On the other hand... if it exists, one ought to read it. I know there is a document in the Tomcat 4 doc set about 'virtual' hosts configuration, which might get you started at least, and there are a number of documents with the Apache manual about the topic... If you have read them, ask questions to clarify what is there, if not,... AFAIK, basically you need to add multiple host / sections in Tomcat's server.xml and 'inside' those, nest the required context / elements, then adjust the parameters to suit each host added to keep them unique It's a similar thing at the Apache end; create VirtualHost sections within httpd.conf, and inside these create Location entries, inside which use 'JkUriSet worker workername'. If you create only one worker in workers2.properties, workername can be the same one for all hosts. Create a channelSocket entry in workers2.properties that points to the Tomcat machine/port. Aim the workername entry at the channelSocket entry and it ought to be very close to going. Norm Hi all. Is there a comprehensive mod_jk2 guide? I'm mostly interested in comprehensive explanation of the syntax and semantcis of worker2.properties and jk2.properties files. The docs coming with TC are confusing and full of holes, to say the least. Right now, my immediate question would be: how to setup Apache 2.0.46 with virtual hosts on one machine to map TC (with virtual hosts) on another machine? For instance: Apache2: HOST: Legba.ev.co.yu (also holding Krb.ev.co.yu) TC 4.1.24: HOST: Mercury.ev.co.yu (also holding Test.ev.co.yu) Coyote HTTP/1.1 connector is working on TC and I can browse to http://Test.ev.co.yu:8080/test/index.jsp (you guys can't, it is on our Intranet :-)). Now, I would like to map a context test from TC:Host:Test.ev.co.yu into /my_test/* under Krb.ev.co.yu hosted on Apache. What exactly should I do? All the examples on the TC-docs make many assumptions or, shall we say, skip a lot of explanation teritory. Also, I've done this (almost) with mod_webapp and it makes sense to monkey around with VHosts under TC - each Apache VHost maps to the corresponding TC VHost, defined under WARP engine. Does it make sense when using JK1/2? Can I map a context defined under one VHost on TC under totally different VHost on Apache? Is there something special in the syntax of workers2.properties in such case? TYIA, Nix. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Question regarding tomcat-apache.conf file.
Just a tad too quick with the 'send'... mod_jk or mod_jk2? If you don't have a preference, go with mod_jk... it has only recently been updated and if you get auto config working, it only supports jk anyway. There are slots at Jakarta for the binaries for mod_jk for different versions of Solaris but are presently empty... do you 'roll-your-own' [compile] or prefer 'ready-made' [binaries]? Solaris is not on my 'accreditation list' so this will be strictly theory... But before going on, best if you nominate your jk(2) module and wether you compile or buy...

JK2 Documentation
Good evening All.
I have a few questions re the configuration and operation of mod_jk2 that I hope some
better informed user may be able to answer.
1. The documentation describes setting parameters in the httpd.conf file using JkSet,
and I have had success with worker parameters, but trying to set something like the
config file keeps eluding me. The 'object' name usually comes from the section head
[config], and since there is no local component name one expects the setting would be:
JkSet config.file conf/filename
However when I start apache2 the following error is generated depending on the form
used:
[Fri Jun 06 20:08:31 2003] [notice] mod_jk2: Unrecognized option config:file
conf/workers2.properties
[Fri Jun 06 20:17:55 2003] [notice] mod_jk2: Unrecognized option config.file
conf/workers2.properties
[Fri Jun 06 20:43:03 2003] [notice] mod_jk2: Unrecognized option config:.file
conf/workers2.properties
[Fri Jun 06 20:45:28 2003] [notice] mod_jk2: Unrecognized option config:file
${serverRoot}/conf/workers2.properties
Can someone enlighten me please?
2. The documentation indicates all objects have three standard properties, namely
'disabled', 'debug' and 'version', yet when 'version=0' is included in
workers2.properties under, for example, ajp13, mod_jk2 reports it as an unrecognised
option. Which is correct, the module or the documents?
3. The basic premise of load balancing is understandable but not the method by which
mod_jk achieves it. If two workers have the same lb_factor of 1, does that imply
every second (unique, assuming sticky sessions) request goes to each Tomcat? ... and
if the lb_factor is raised to 5 each? 5 to one then 5 the other?
If one Tomcat has an lb_factor of 20 and the other 2, does one do ten times the 'work'
and if so how is this 'measured'? ...over a period of time, by counters, by preference?
I've read mod_jk2 is still a work in progress but hope the questions might provide at
least a few ideas for inclusions.
Thanks in advance for any reply,
Norm

Given that I couldn't put the dll to much use (I was mostly curious to see the 'status' ouput) I left it at that in hope the next release of JK2 provides docs that allow a functional spec of the module to be derived... from which a port to Netware might be created. Wether this was a bug carried over from the source or a corrupted dll I couldn't say, but your experience suggests it might be in the source.

User Interface To Tomcat User List
Good afternoon All. Only new to the Tomcat User Mail List and may likely opt out soon to conserve my Inbox, but wanted to say that getting 91 emails in one session (2 were relevant to the question I asked) isn't helping me or likely of much use to anyone else for that matter either. (Perhaps my ISP who charges by the amount downloaded?) I have limited exposure to Tomcat and the docs and config files to some extent, so I probably could help a few, but not if I have to keep clearing my my Inbox every hour or so. Newsgroups are what I got used to for Netware, with the various products broken up into different categories like install, utils and so on, that ANYONE can browse, and if you see a message that you can offer some help to, just click on 'reply to group', say your piece and send; no cluttered Inboxes and, I suspect, a lot less traffic for the server. A moderator (unknown) vets/removes anything of a stupid/antisocial nature, and in five plus years that I've experienced it, it seems to have worked well. I've received emails recently that are proposing eForum(s), and, while the format is unknown to me, believe there is a sound basis for looking at changing the way the users list works, regardless of the method used. $0.02 Norm

Well, we'll see if apache group responds to my bug 12186. I know how you feel about all the emails from these lists. I wish they would add an option to just let you flag topics that you want to watch and forget the rest. I took a yahoo account with 4MB limit just to discpline myself to manage the different maillist inboxes. I either manage it or I cannot send or receive mail - great incentive.

Tomcat 3.3 to 4.1 - Changes?
Good evening All. Working with Tomcat on Netware (no cringing please). Trying to upgrade Tomcat from 3.3 to 4.1.x (current). - Has the 'ContextXMLReader' directives/function been dropped in the latest releases? (Cannot find reference to it in the Docs and cannot get it to work on 4.1) - Will Tomcat 4.1.x work with web apps outside its own webapps directory? Have set the docBase var for the context to an absolute path sys:/.. (etc) (I get the impression it's not reading the associated web.xml file) TIA Norm
Re: Tomcat 3.3 to 4.1 - Changes?
Good morning Craig. Hope you get to read this.. (ie this system has me confused after working with newsgroups). Thanks for the feedback. Will try changes based on your suggestions and go from there.

(Cannot find reference to it in the Docs and cannot get it to work on 4.1) Tomcat 4.x and 5.x haven't ever had anything exactly like ContextXMLReader. A somewhat similar capability is to put just an XML file containing a Context element into the webapps directory (this is how the admin and manager webapps are configured by default). - Will Tomcat 4.1.x work with web apps outside its own webapps directory? Have set the docBase var for the context to an absolute path sys:/.. (etc) (I get the impression it's not reading the associated web.xml file) You have to use a path that the JDK considers to be absolute (i.e. something that java.io.File.isAbsolute() will return true for). All other paths are interpreted as relative to the appBase directory of the Host element.

Re: JK2
Good morning Chris. The download page for mod_jk2-2.0.43.dll suggests it will ONLY work for that version of Apache and no other; hence... I installed 2.0.43 win version of Apache2 (NT box). The module 'loads' without error, but a syntax check (-t) of the httpd.conf (with LoadModule and JK directives) failed on each Jkxxx directive, as if the module wasn't exporting the Directives to Apache on loading. I had IfModule mod_jk2.c ahead of the Jkxxx commands in the httpd.conf so I know it could see the module itself.
