Cannot get tomcat 4 cluster working with sticky sessions

[Yefym]

I have Apache/2.0.45 running on the server A
And two tomcat workers are running on B and C

The problem is that I cannot get Tomcat cluster load
balanced with sticky sessions support. Playing around with workers.properties on
Apache gave me two different situations.
1.if I have local_worker parameter equal to 1, then
I have no lost sessions but also no loadbalancing . But
cluster is still fail safe, if one tomcat dies - another
one gets all incoming requests.
2. if I have local_worker=0 then I have a simple round-
robin balancer without session affinity. So my session got lost.


configuration example workers.properties:
worker.list=tomcat-worker-01,tomcat-worker-02,router
worker.tomcat-worker-02.port=4007
worker.tomcat-worker-02.host=xxx.xx.x.12
worker.tomcat-worker-02.type=ajp13
worker.tomcat-worker-02.lbfactor=50
worker.tomcat-worker-02.cachesize=10
worker.tomcat-worker-02.cache_timeout=600
worker.tomcat-worker-02.socket_timeout=300
worker.tomcat-worker-02.local_worker=1
worker.tomcat-worker-01.port=5007
worker.tomcat-worker-01.host=xxx.xx.x.20
worker.tomcat-worker-01.type=ajp13
worker.tomcat-worker-01.lbfactor=50
worker.tomcat-worker-01.cachesize=10
worker.tomcat-worker-01.cache_timeout=600
worker.tomcat-worker-01.socket_timeout=300
worker.tomcat-worker-01.local_worker=1
worker.router.type=lb
worker.router.balanced_workers=tomcat-worker-01,tomcat-worker-02
worker.router.sticky_session =1
worker.router.local_worker_only=1


SOS! any helpful hints would be useful.

Hi , some additional information .
I've got with mozilla LiveHTTPHeaders that my session cookie doesn't recieve Jvmroute parameter , so apache doesn't know anything about load-balancing .
Cookie: JSESSIONID=5387242C819757A9BC12B2FAF1AF2AD8;


Does anybody have any suggestion or idea?

P.S.
No errors or exceptions in mod_jk.log were found.

Hi people, I still have no any progress , I've installed the newest version of tomcat 4.1.27 and build mod_jk from the sources.
Still the same : all requests are sent to one tomcat , but if I shutdown it apache redirects the work to another one
No error messages, in mod_jk.log I see that two balanced workers were found.
Lots of web links say that load-balancing work , but in reallity they all point to one from Pascal Forget.

I even cannot view anything added by tomcat to my session cookie.



There are some conf files bellow.

Any help or suggestion would be highly appreciated.


P.S. My topic is still not in tomcat-users list. So what are criterias to put it there?

Hi Yefym,

Hmm still having problems eh!

Take a look at the following and work through a simplified workers configuration .....

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

I know its Apache 1.3.23 but the concept is the same I think.

We have had no problems using sticky and loadbalance with the ajp solution, also have a look at the following thread where I steered another lost soul through the same process -> thread877-564269 me know how you get on?

Good Luck,
Laurie.

Please check this thread on tomcat-users forum.
http://www.mail-archive.com/tomcat-user@jakarta.apache.org/msg102581.html

I think I made all nescessary configuration specified by Pascal Forget.

I suppose that I made mistake somewhere and I need help to locate it.

thnx.

How many &quot;test client machines&quot; are you using?

You will not see any load balance if you are only using one test client.

Are you sure you understand that a secession (once attached with sticky) will remain with that cluster node for the duration of that secession? (So no loadbalance required after that point) the next client will (maybe) hook onto another cluster node (for the duration of that secession) and so on ........

You will not loadbalance a sticky connection over many cluster nodes.

Hope this helps,
Laurie

Hi tarn. I'm using several load generators (hosts) for the test.


The problem is that the same session distributed through several tomcat nodes, instead of be forwarded to the same one.

this behaviour U can see in the logfiles which I posted to the tomcat_users forum, here is the most interesting part :

&quot;So the result is that the same session processed by both tomcats but with right worker specified :

tomcat1:
2003-08-29 16:49:26 RequestDumperValve[Standalone]:
cookie=JSESSIONID=19E9FD015AF34C5181322F3FEF37B0D6.tomcat-worker-01




tomcat2:
003-08-29 16:50:10 RequestDumperValve[Standalone]:
header=cookie=JSESSIONID=19E9FD015AF34C5181322F3FEF37B0D6.tomcat-worker-01;




this could work if session is replicated on all tomcat servers but not in
a current state.
&quot;

SESSIONID is the same... worker is the same , but it processed by both tomcat using round-robin algorithm.


Do U have any idea ?


here is the link to tomcat forum thread:

http://www.mail-archive.com/tomcat-user@jakarta.apache.org/msg102790.html

Ok more information herebut read on >>)

http://jakarta.apache.org/tomcat/tomcat-4.0-doc/config/engine.html

You have a TYPO in your posting earlyer >>
server.xml has these lines related to apache-tomcat interaction:
<Engine jmvRoute=&quot;tomcat-worker-01&quot; name=&quot;Standalone&quot; defaultHost=&quot;172.31.7.20&quot; debug=&quot;1&quot;>
<Connector className=&quot;org.apache.ajp.tomcat4.Ajp13Connector&quot;
port=&quot;5007&quot; acceptCount=&quot;10&quot; debug=&quot;0&quot;/>

It should be jvmRoute!!! and must be unique across ALL tomcats in the cluster ..... see information at above link.

I hope its just that??

Good Luck,
Laurie.

Hi Laurie , unfortunetly U are not copletely right )))

If U check tomcat-users forum &quot;

http://www.mail-archive.com/tomcat-user@jakarta.apache.org/index.html&quot;

, searching for &quot;Yefym&quot; - U will get detailes )))

The summary is that JvmRoute was fixed ))) , so I got worker added to the sessionID. But the same session still distributed to the several hosts.

Any idea?


thnx for your help.

Correction I was right! You did have a typo and there is nothing here in this forum posting to say you had resolved it, unfortunately I don’t have time to subscribe to other forums so I would have not seen your postings else ware.

I have not seen your httpd.conf so can I assume that you have the correct configuration for load balance?

My example: ......

# mod_jk directives
LoadModule dir_module modules/mod_dir.so
LoadModule jk_module modules/mod_jk.so
AddModule mod_jk.c
#
# Configure mod_jk
#
JkWorkersFile conf/workers.properties
JKLogFile logs/mod_jk.log
JkLogLevel info
#JkLogLevel debug
JkMount / loadbalancer
JkMount /* loadbalancer

If so then I can only repeat that you should study the

http://jakarta.apache.org/tomcat/tomcat-4.0-doc/

information and if your configuration is absolutely correct and you still cannot resolve your problem, then you should contact the apache developers directly?

Sorry but again hope this helps.
Laurie.
