Load Balancing in OFbiz

Hi,

I want to load balance OFBiz requests using multiple servers(server
cluster). Do i need to use multiple tomcat instances for that?? Is there
any other efficient way to go for the same..

I need to set up session replication using embedded tomcat but i am not
able to get any concrete steps to go ahead. Do i need multiple tomcat
instances running on different servers respective to same OFBiz code base
?? or different OFBiz deployed on different application servers?

Thanks & Regards,
Neha Mehta

Re: Load Balancing in OFbiz

Neha,

Here is a configuration we use to do load balancing in ofbiz. Others may do
something else.

1. One machine is running an Apache Web server with mod_jk setup to
communicate with different instances of ofbiz. The mod_jk is setup to load
balance between the different ofbiz instances. Here is a document that
helps you get setup:

http://tomcat.apache.org/connectors-doc/generic_howto/loadbalancers.html

2. Then we start multiple boxes running ofbiz server - all pointing to the
same database. The servers are setup to communicate using mod_jk's AJP
protocol. You need to set the "jvm-route" in the
framework/base/config/ofbiz-containers.xml file to insure the load balancer
maintains sessions between requests. Here is a snippet of that
configuration file.

<container name="catalina-container"
class="org.ofbiz.catalina.container.CatalinaContainer">

<property name="delegator-name" value="default"/>
<property name="use-naming" value="false"/>
<property name="debug" value="0"/>
<property name="catalina-runtime-home" value="runtime/catalina"/>
<property name="apps-context-reloadable" value="false"/>
<property name="apps-cross-context" value="false"/>
<property name="apps-distributable" value="false"/>

<property name="default-server" value="engine">
<property name="default-host" value="0.0.0.0"/>
*<property name="jvm-route" value="jvm1"/>*
<property name="access-log-pattern">
.....

3. One large box is running our database server.

We've been please with how well the Apache load balancing module works with
ofbiz.

Hi Neha,

because OFBiz is using Tomcat V5 check on the internet how to load
balance tomcat together with apache.

there is a lot of text on that, an example:
http://tomcat.apache.org/tomcat-5.5-doc/balancer-howto.html

Hi Brett,

Thanx for your generosity.
I have to load balance OFBiz on multiple servers. For this do i need to
have replica of my OFBiz code running on multiple servers and run embedded
OFBiz tomcat on all these servers??? Or do i need to have multiple tomcat
instances on a single server?? ALso please let me know, is it better to
use embedded tomcat or external tomcat for load balancing ??

All the forums that i have read talk about running multiple tomcat
instances on same server.. I do not understand the reason behind this..
Kindly help me out.

Thanks & Regards,
Neha Mehta

Re: Load Balancing in OFbiz

1. We run one instance of ofbiz on a separate server but this is because we
are running a single application and want to scale by adding more machines.

2. It is easier to use the embedded ofbiz version rather than a standalone
tomcat with ofbiz placed as a standard WAR file. From the Apache Web server
perspective there isn't any difference. It is talking AJP protocol and
can't tell if it is an embedded version of tomcat or standalone.

3. I'm not sure the reason some are running several version of ofbiz on the
same machine. My guess is they have different customers or application and
don't need the extra hardware to service these applications. We multiple
instances of ofbiz on the same machine but this is so we can have a dev,
testing, and production version running on the same machine.

For maximum scalability you would put 1 instance of ofbiz on a single
machine and load balance between these machines. We are using Amazon's EC2
servers so it is easy for us to shutdown to a single server at night and
then start up several server during the days when the application is busy.

Re: Load Balancing in OFbiz

and Yes, you need to replicate the same code on all the different machines.
We have used subversion to do this as you only need to update each server
to the version you want to run. Then manually modify some config files such
as the jvm path that I indicated earlier and your up and running.

Re: Load Balancing in OFbiz

In reply to this post by Brett

Hi,

I need to load balance OFBiz among multiple servers.
For this i have used Apache Http server in front of OFBiz. I have done the
necessary changes in apache http server:
1. In httpd.conf :
LoadModule jk_module modules/mod_jk.so
JkWorkersFile conf/workers.properties
JkShmFile logs/mod_jk.shm
JkLogFile logs/mod_jk.log
JkLogLevel info
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
JkMount /* worker1
2. In workers.properties :
worker.list=worker1
worker.worker1.type=ajp13
worker.worker1.host=172.17.88.52
worker.worker1.port=8009

The server is listening on port 80.

On OFBiz side, i have set jvm route in ofbiz-containers.xml :
<container name="catalina-container" class=
"org.ofbiz.catalina.container.CatalinaContainer">

<property name="delegator-name" value="default"/>
<property name="use-naming" value="false"/>
<property name="debug" value="0"/>
<property name="catalina-runtime-home" value="runtime/catalina"/>
<property name="apps-context-reloadable" value="false"/>
<property name="apps-cross-context" value="false"/>
<property name="apps-distributable" value="false"/>

<property name="default-server" value="engine">
<property name="default-host" value="0.0.0.0"/>
<property name="jvm-route" value="jvm1"/>
<property name="access-log-pattern">

OFBiz' embedded tomcat runs ajp on port 8009.

I am trying to access the OFBiz application using :
http://172.17.88.52/ecommerce/control/main
I am not able to get the required page.
Can you please let me know the step i am missing...

Thanks & Regards,

Re: Load Balancing in OFbiz

If your Apache is 2.2.x, you should use mod_proxy rather than mod_jk.

Re: Load Balancing in OFbiz

Hi,

Thanx for your reply, i used mod_proxy but was completely unable to
conenct Apache Server with OFBiz. So i switched to mod_jk to get an
experience of load balncing first and then switch to mod_proxy again.
Could you please provide me with an appropriate help that could lead me to
get OFBiz load balnced using mod_proxy

Thanks & Regards,

In reply to this post by Shi Jinghai

Hi Shi,

allow me to point at:

-
http://blog.jboss.org/blog/mturk/2007/07/16/Comparing_mod_proxy_and_mod_jk.txt

- http://anilsaldhana.blogspot.com/2006/04/modjk-versus-modproxy.html

(and that's just the first two hits from Google using "apache mod_jk vs
mod_proxy")

So as a summary, your statement sounds too easy to reflect reality. If you
are performance (=production?) oriented, there is still very good reasons to
stay with mod_jk, despite the fact that it requires more configuration work.

Further (just as a hint): Sites which are subject to PCI DSS scans, will be
required to run at Apache 2.2.11 at least (unless they chose to go the
WAF-way for web security).

As this entire thread is addressing topics that I have repeatedly tried to
"tweak" out of the community, I will take all this and club the info
together for a HOWTO page in the wiki.

Thanks all for the information provided. I knew there are folks out there
running horizontally scaled OFBizes.

Carsten

Re: Load Balancing in OFbiz

Hi,

Thanx a lot for the help.I have been able to load balance multiple OFBiz
servers using Apache Httpd Server and mod_jk.
But it is working with session stickiness. Can anybody help me in running
load balanced servers in session replication mode.

Thanks & Regards,
Neha Mehta
