It took a long time and a lot of work but finally, we are proud to announce that we changed the DNS yesterday and you will start to see the new http://www.greenpeace.org/ site running on OpenACS 4.5.
It might take as much as 48 hours to have all the DNS have the new IP address and some time as well for Akamai to get the new images and URLs, so you might see some errors still.

I want to publicly thank Don Baccus and Furfly, Lars Pind and Collaboraid, Museatech (Luke Pond and Talli Somekh), Open Force (Ben Adida and Joshua Hecht), Dave Bauer, Bart Teeuwisse and of course ALL of you that make this software a reality (coders or not).

In the Amsterdam Social tomorrow, we will try to explain a bit more the history on how we got to this point ... For those who won't be able to make it, we have plans to write some "lessons learned, experience on building a site from scratch using OpenACS" docs.

We, at Greenpeace, really think that this software and the community around it, are great assets for the NGO world and we will continue to work and collaborate as we have tried so far.

Hope you enjoy the new site and that you help us make this a better world to live in. (I can't help being a Greenpeace activist as well)

Congratulations Bruno! Looks great.  Very much looking forward to your lessons learned document and hopefully using much of your work in the future.

Congratulations to all involved for this great accomplishment!

Hola, Bruno:

Enhorabuena por el sitio!.

Could you give us a hardware description of the machines who are supporting the site?

Thanks.

is the site running oracle or postgres?

Bruno's posted some stats.  It's worth noting that we're doing some caching of these highly dynamic pages (each of the menu panels you see are constructed by queries on content, as well as the main content portion of the page).  While serving 100,000 pages to 16,000 users on one day with caching of much content set to five minutes, the load on the two webservers was in the 0.3 range, while the database server was barely ticking over.  We're only doing partial caching of dynamic content so we're pretty happy with the performance thus far.  A modern dual-processor AMD-based system with DDR would outperform the Sun server, but we're doing OK with what we've got and Sun systems are extremely well-built, of course.

Hello Jorge

I will reply in english for the rest of the list as well

The two intel based machines are used as web servers only, and the Sun server only for Oracle. Oracle might use the two processors, I don't really know the inner details on how multithreaded Oracle is and how it works on Solaris but I presume that it will make use of the second processor when needed.

We have a site, called the cybercentre, built in Zope and it's not static at all, it has some discussion forums, a la slashdot. The main site (www.greenpeace.org) is built using OpenACS.

And yes, the two web servers are behind a load balancer. I don't have the details of it since that is provided and maintained by the hosting company. I never had to deal with that, fortunately

Michael ... I will post some experiences as soon as I get back from holidays :) I am leaving now ... Just wanted to post a bit more stats:
