Tomcat 5.5.15 Clustering ?
Hi,
I' ve try to use Tomcat 5.5.15 in cluster mod. And after some work on
configuration and test
i seems to be on limit of my all possibilities ;)
I try to use two tomcat in cluster with apache web server and mod_jk as
connector.
my Apache configuration look like :
# workers.properties
ps=/
# List the workers name
worker.list=loadbalancer
# ----------------
# First worker
# ----------------
worker.node01.port=8009
worker.node01.host=agnes
worker.node01.type=ajp13
worker.node01.lbfactor=1
#worker.node01.domain=cluster1
# ----------------
# Second worker
# ----------------
worker.node02.port=9009
worker.node02.host=ovea-inspiron
worker.node02.type=ajp13
worker.node02.lbfactor=1
#worker.node02.domain=cluster1
# ----------------------
# Load Balancer worker
# ----------------------
worker.loadbalancer.type=lb
worker.loadbalancer.sticky_session=false
worker.loadbalancer.balanced_workers=node01,node02
As you can see i use two server ('agnes' IP : 192.168.2.102 and
'ovea-inspiron' IP : 192.168.2.103)
I' ve coded a little aplication who read un file and create a sessions if
session not exist.
If i use the system in mod load balancing (with no cluster mod activate)
all is great (my config is of course worker.loadbalancer.sticky_session=true
)
So system run with session affinitu but the two server are accessible ;)
Now i try to configure as cluster mode with session replication
(my config is now worker.loadbalancer.sticky_session=3Dfalse)
I configure my to server.xml like that :

I'm user linux so i've compiled my kernel with multicat kernel option
I add the rout like rooute add -host 224.0.0.1 dev eth0
N.B : why 224.0.0.1 => http://www.iana.org/assignments/multicast-addresses
So route is :
ALL-SYSTEMS.MCA * 255.255.255.255 UH 0 0 0 eth0
192.168.2.0 * 255.255.255.0 U 0 0 0
eth0
loopback * 255.0.0.0 U 0 0
0 lo
default . 0.0.0.0 UG 0 0
0 eth0
now i start the two tomcat with the same application in webapp directories
with tcpdump i verify the multicasting btewen my server .. so :

As you can see in the last line cluster member are not found !!!!
What's the hell ;)
When i test my application i've always the sequences :
This page is rendered on server : *Cluster Node - 01 (One) New session is
created with saved value ....UserId : 123456
This page is rendered on server : *Cluster Node - 02 (Two) New session is
created with saved value ....UserId : 123456
This page is rendered on server : *Cluster Node - 01 (One) New session is
created with saved value ....UserId : 123456
So the request is well balanced but a new session is alway created !!!!!
Some ideas ...
Thank you guys

Yes you're right i' ve a problem in my /etc/hosts as you can see in my
response
to Hanik.
I hope this type of thread can help people to save time.
Because some skills are necessary for reolve the problem.
Thank you Paul ;)

Is the multicast going over the 127.0.0.1 instead? We've had this
problem before (redhat el3), and to fix it, you have to make sure
that in /etc/hosts that localhost is bound to a real IP address and
not 127.0.0.1. for some reason, in Java it always seems to want to
stick to the local interface when localhost is mapped to this.

APR is not yet planned for the clustering component. but is on the to do
list
waitForAck is not related to APR, its a NIO problem between Java and
your OS platform.

Ok so question .. if I configure my tomcat with apr (Apache Portable
Runtime)
it's isue be solved ?
I've listen that futur version of Tomcat will embed APR as natif and i can
run Tomcat
without apache in fronted with same performance and with support of other
scripring language like PHP !!!!
Is it true ? ;)

you're welcome, glad I could help.
there is one problem that you have on your linux box, NIO is not working
properly,
so disabling acknowledgements solved that problem (waitForAck="false")

OK i continu to explore this multicast problem on my boxes
So what i've learn !!!!
I learn that it's right to develop J2EE application on Linux.
I can see very quickly problem that i can find in production infrastructure.
i'm sure on windows all my problemes was be masked.
It's improve my knlowledge of Linux system and network.
It's fun for a developper like me too learn about system.
Now i need to modifiy my real application to support clustering.
Thank you again ;)

Re: Tomcat 5.5.15 Clustering ?
Posted by Filip Hanik - Dev Lists <de...@hanik.com>.
Perfect David, and as far as I can tell, the latter sequence that you

now, obviously your system is not setup correctly to bind an interface
to the multicasting, so don't do it if it works without it.
so what have you learned? :)

I look on first tomcat log and nothing change
Ok now my two apps are deployed ... i start my apache
do i my first request => result :
Demo This page is rendered on server : Cluster Node - 01 (One) New
session is created with saved value ....UserId : 123456
do i my second request => result :
Demo This page is rendered on server : Cluster Node - 02 (Two) New
session is created with saved value ....UserId : 123456
Nothing new in the two tomcat log.
So no session replication a new session is created on each server ;(
II - WITHOUT mcastBindAddress
Shutdown the MCaster program => Ok
hutdown both Tomcats - delete or archive your logs => Ok
set waitForAck="false" on your <Sender> element => Ok (I keep your
config here to see ;))
Start tomcat 1 => OK ... logs are :

Ok now my two apps are deployed ... i start my apache
do i my first request => result :
Demo This page is rendered on server : Cluster Node - 01 (One) New
session is created with saved value ....UserId : 123456
do i my second request => result :
Demo This page is rendered on server : Cluster Node - 02 (Two) Session
already exist with saved value ....UserId : 123456
So session replication is OK ;) on session created and duplicated on
the other server
New logs are present in my two boxes :

wow, apologies for being blunt in advance, not my style, but you really
really really need to slow down and you need to start reading carefully
so that we can get this out of the way.
1. The output from MCaster that we are looking for is when MCaster is
running on both boxes, and tomcat is NOT(!) running.
Please provide that output, what I am looking for is your pure
MCaster messages, not cluttered with tomcat's messages.
You could have done this way back when if you had read carefully
:).Dont take free support for granted :)
>For the next steps wich configuration do you want ?

both. does Tomcat recognize membership on both settings now? or still
only without the mcastBindAddress attribute?
Then follow these steps
1. Shutdown the MCaster program
2. Shutdown both Tomcats - delete or archive your logs
3. Set waitForAck="false" on your <Sender> element
4. Start tomcat 1
5. Wait 10 seconds
6. Start tomcat 2
7. Send us your new output from tomcat

Now tell us

2. Java version
- Sun JDK 1.5.0.06
OK in response of your previous message.
I start the two servers and run MCast
output is :

with or without mcastBindAddress in server.xml configuration
Then follow these steps
1. Shutdown the MCaster program
2. Shutdown both Tomcats - delete or archive your logs

4. Start tomcat 1
5. Wait 10 seconds
6. Start tomcat 2

Then follow these steps
1. Shutdown the MCaster program
2. Shutdown both Tomcats - delete or archive your logs
3. Set waitForAck="false" on your <Sender> element
4. Start tomcat 1
5. Wait 10 seconds

ok, we will work through it one item at the time.
show me the output from both servers MCaster program (not the tcpdump)
when they run simultanously.

You're right so :
1 - I reboot my too servers agnes : 192.168.2.102 and ovea-inspiron :
192.168.2.103
2 - I test the multicat on each server
for that, I start on agnes the command
java -cp tomcat-replication.jar MCaster 224.0.0.1 45564 ovea-inspiron
output :

Ok here first problem in the first server name of agnes is not
resolved !!!!
so i take a look on my hosts and a see the problem !!!!
fuck ... bad configuration
it's
127.0.0.1 localhost agnes
192.168.2.103 ovea-inspiron
but must be
127.0.0.1 localhost
192.168.2.102 agnes
192.168.2.103 ovea-inspiron
same error on second server so i correct this mistake
and retry the test ... ok name is resolved as well.
Now i run the command simultany on two servers
on agnes the command java -cp tomcat-replication.jar MCaster
224.0.0.1 45564 ovea-inspiron
and on ovea-inspiron start comand : java -cp
tomcat-replication.jar MCaster 224.0.0.1 45564 agnes
the ouput as the same a the other tests but tcpdump info are now :

I don't always know why I need remove my mcastBindAddress
So a big thank you for all you help me to explore other way ;)

Re: Tomcat 5.5.15 Clustering ?
Posted by Filip Hanik - Dev Lists <de...@hanik.com>.
David, you are all over the place. Slow down for a second.
my guess is that one of your interfaces is not doing what you think it
is doing.
follow these simple steps
1. Make sure that your multicast is working
2. Stop all your tomcat processes
3. Make sure nothing else is broadcasting on the same mcast address
4. Delete or archive all your previous logs
5. Startup tomcat 1 - wait 10 seconds
6. Startup tomcat 2
Then do the following
7. Set tcpListenAddress="auto" in your server.xml file
8. Repeat steps 1 through 6
9. email the logs to the list
our guess is that you have a networking problem, but you just don't dont
look into it close enough for yourself and then provide us with the info.

Re: Tomcat 5.5.15 Clustering ?
Posted by David Avenante <d....@gmail.com>.
Yes MULTICAST is enabled i see that by too fact :
first,
ifconfig eth0 :
eth0 Link encap:Ethernet HWaddr 00:13:D4:45:A6:3F
inet addr:192.168.2.102 Bcast:192.168.2.255 Mask:255.255.255.0
UP BROADCAST NOTRAILERS RUNNING ALLMULTI MULTICAST MTU:1500
Metric:1
RX packets:264493 errors:0 dropped:0 overruns:0 frame:0
TX packets:292063 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:98079150 (93.5 Mb) TX bytes:41007393 (39.1 Mb)
ALLMULTI and MULTICAST is enabled on two serveur interface.
second,
as you see in my first post tcpdump track the UDP messages send between
server.
For sticky_session=true i' m not agree with you.
In the connector documentation (see
http://tomcat.apache.org/connectors-doc/config/workers.html)
=> Set sticky_session to *False* when Tomcat is using a Session Manager
which can persist session data across multiple instances of Tomcat
It' s my situation.
So i' m alway in the trouble by thanks a lot for the verification ;)

Re: Tomcat 5.5.15 Clustering ?
Posted by Filip Hanik - Dev Lists <de...@hanik.com>.
It is a multicast problem, your second box is not receiving any
multicast messages, only from itself.
To run this test properly, you will need to shutdown your tomcats, then
run MCaster on both machines at the same time,
if both machines are not receiving messages from each other (like your
example below) then you have a multicast problem

Re: Tomcat 5.5.15 Clustering ?
Posted by David Avenante <d....@gmail.com>.
Thank you very much for the toolkit ;)
My feeling was also on my multicast support.
But i' ve read more documentation for my Linux
and i think that my servers support MULTICAST like
explaned on my first message (compile kernel support
and add route + test with tcpdump)
So this toolkit seems confirme the fact that my servers support multicast.
When i test on agnes with target ovea-inspiron i've:
java -cp tomcat-replication.jar MCaster 224.0.0.1 45564 ovea-inspiron
Usage MCaster [address port message]
BEGIN TO RECEIVE
SENT:ovea-inspiron1
RECEIVED:ovea-inspiron1 FROM /192.168.2.102:45564
SENT:ovea-inspiron2
BEGIN TO RECEIVE
RECEIVED:(gtcp://192.168.2.103:400cluster1 FROM /192.168.2.103:45564
SENT:ovea-inspiron3
BEGIN TO RECEIVE
RECEIVED:(ftcp://192.168.2.102:400catalina FROM /192.168.2.102:45564
SENT:ovea-inspiron4
BEGIN TO RECEIVE
RECEIVED:(gtcp://192.168.2.103:400cluster1 FROM /192.168.2.103:45564
And when i test on ovea-inspiron with target agnes i've:
java -cp tomcat-replication.jar MCaster 224.0.0.1 <http://228.1.2.3/> 45566
agnes
Usage MCaster [address port message]
BEGIN TO RECEIVE
SENT:agnes1
RECEIVED:agnes1 FROM /192.168.2.103:45566
SENT:agnes2
BEGIN TO RECEIVE
RECEIVED:agnes2 FROM /192.168.2.103:45566
SENT:agnes3
BEGIN TO RECEIVE
RECEIVED:agnes3 FROM /192.168.2.103:45566
SENT:agnes4
BEGIN TO RECEIVE
RECEIVED:agnes4 FROM /192.168.2.103:45566
SENT:agnes5
BEGIN TO RECEIVE
RECEIVED:agnes5 FROM /192.168.2.103:45566
SENT:agnes6
BEGIN TO RECEIVE
RECEIVED:agnes6 FROM /192.168.2.103:45566
SENT:agnes7
BEGIN TO RECEIVE
RECEIVED:agnes7 FROM /192.168.2.103:45566
So it's not a multicast probleme but most a configuration probleme.
ovea-inspiron sent is ok but the received is empty ?
Some suggestion(s) ?
Thank's for the progress

OK, yes, for special application we support it, but normaly
sticky_session is true. See Servlet Spec (SRV 7.7).

Re: Tomcat 5.5.15 Clustering ?
Posted by Filip Hanik - Dev Lists <de...@hanik.com>.
>1) Clustering need sticky_session=true and is only design for
failover (see servlet spec).
Not true for Tomcat, using replicationMode="pooled" and
waitForAck="true", you can do round robin non sticky load balancing as
long as you don't have more than one thread accessing the session at any
point in time.
>INFO: Manager [/cluster-1.0-SNAPSHOT]: skipping state transfer. No
members active in cluster group.
yes, your multicast isn't working, or it should have said that you had a
member.
Take a look at the bottom of the page and run the MCaster test included
in a super old version of Tomcat 4 clustering.
http://people.apache.org/~fhanik/
On multihomed hosts, it can get a little tricky to get multicasting
working and you might have to setup some routes to help. Check with your
sysadmin.
