Hi!

It's my first post, and I am completely new to Jetspeed, so bear with me
please.

The idea is to deploy a portal on n machines, where n is 4 at the
moment. We would like to have some pretty load balancers in front of
them, the boxes are located in two countries. As this is usual for good
portals, the user/customer should not care about where he is.

The jetspeed-2 installation will access an oracle 10 database. Now
there's my question: Since it doesn't make sense (IMHO) to put the
oracle beast on all the 4 machines, is it possible to have all 4
jetspeed installations access the same database? Or even, the same
tablespace? Or do I have to create users for each server?

I have clustered Jetspeed 1.6-dev and 1.5 in several installations.

Jetspeed-2 is not quite cluster ready, but I think it was designed much better than Jetspeed-1 for clustering. Many of the components already persist their state in a database, so therer is not a lot of need for tweaking the implementations like we had to do in 1.6.

The plan is to work on clustering for the final release.

Current problems I see with Jetspeed-2 and clustering:

* PSML stored on the file system
* lots of use of the session
* cache synchronization on a number of components

Is there a clustering guide somewhere? I am quite stuck at the moment,
to be honest.

Thanks for your kind help in advance

Cheers

André
