Florin,
I'm not sure what you mean when you say apache talke with ofbiz instances
via AJP rather than mod_jk. I thought mod_jk used AJP.
I would be interested if you find that AJP is a bottleneck. We use a
configuration with Apache on the front end and ofbiz on behind it. We use
mod_jk
Hi,
Today is planned to switch from AJP to mod_jk...I will let you know the
differences.
How did I reached that point: a simple tool

I tried to hit the Apache server only like /usr/local/apache2/bin/ab -c

Hi,
It seems I was on a false track... the tests hits directly against ofbiz
(without Apache in front) did not work properly.. now they do and I only
get max 2-3 req.sec...
What could be wrong configured?
I tried similar hits against one simple tomcat and on 30 secs I reach
5 req/sec.
Florin,
Have you tried using Apache's mod_proxy instead of mod_jk?
I'm not surprised that you get faster responses directly from Apache but 2-3
req/sec doesn't sound good for Tomcat either.
I'll try this same tool in our configuration and see what we get.
For us we configure mod_jk to
Hi,
It is even worse for me... I dropped the tests regarding apache and I
tried tests directly against one ofbiz instance, without any apache in
front..using the same apache ab tool.
I never exceee 3-4 requests per second :(
I tried also to hit one static page and I reach arround 2000
Thanks everyone for the help!
Today we succeeded port to geronimo transaction 2.1 as well as the
switch from minerva to DBCP connection pool. It seems much better but I
am not fully content :)
Maybe because the automated testing tool I am using can not really hit
hard enough..
Any
The Grinder is a nice tool for such things (and has a nice recording proxy).
BTW, make sure to set your HTTP and thread pool sizes adequately for the load
you are planning on.

Sorry for the slow reply Florin, this slipped past me until I saw your message
to Jacques a moment ago.
Could you provide more details about what changes you've made to this checkout?
My first guess is that there's something wrong with the database connection
since the problem appears during
Hi,
There were a lot of changes done... but nothing inside the core of the
project as well as nothing related to the DB layer..
I start 90 concurrent users, they all perform well for a while, aprox 10
mins with a single Ofbiz instance (in production I have 2 instances with

Okay but what approach are you taking currently? Is this an attempt to back
port the transaction management changes or are you updating OFBiz to a recent
revision?

I was just asking myself if someone encountered before such problems on
older revisions..
Would be Geronimo ok to be used or shall I try something else?

I upgraded 2 systems from Minerva (R4.0) to DBCP for clients of mine but I don't know if it's the kind of problems you encounter. It
seems that you are facing more. Not sure as I have, like you, not much time to look at it

You're using a quite old version of OFBiz with the Minerva connection pool (I
can tell from the stack trace you sent earlier). The Minerva connection pool
has some issues with resetting connections when there are errors, especially if
there is any code that doesn't manage errors well, but also
And even after that you would need to enhance the system with change done since that. Especially is you use a system with a load
balancer. But Minerva to DBCP is the big one, yes

Hello all,
We started to develop an e-commerce application based on Ofbiz framework
around 2 years ago.
The version we started from is a revision 691692.
Main problem is that we already have few systems launched into
production, based on that revision.
Meanwhile, doing some mass tests, we
Given the amount of changes required to back port you're probably better to
upgrade to a newer revision, depending on how you've handled your custom code
and what tests you have in place to verify your main areas of functionality, it
should be relatively straightforward.
