Yup!
:-)

Open source rant:

Some people just do not care about profitably until they are laying
people of, because their competitors are more profitable.

It's like being on a project where people have a short deadline:
-we do not have time to unit test
-we do not have time to do it right and use O.O.
OK, I understand.

They all will eventually, just plot the curve until they are all open
source: ( a bit overused, but I love this chart)

Saving money is good.

Thanks Vic.

We allready used PostgreSQL on a "non strategic" project, but our customers aren't 
open-source addicts (until they need
to reduce costs !)

Re: question on heavy load website design using struts

FYI, one site I worked on P&T (performance and tuning) we improved
performance by removing replication.
Also look at postgresql.org, it is much like Oracle.

(self-promo: keep me in mind for engineering larger sites, I have some
useful experience with good ROI)

Sure! Only a little bit patience,please.It may take me
one or two weeks to go over the test.I used to meet a
problem on container managed security using jboss
cluster.That is,jboss'clusterring feature works fine
except when I use declarative security model to
protect my page,the authenticated principal will not
get replicated across the members in the cluster.At
this time,I want to find a work around to that too.

Again,thaks for your info.

Re: question on heavy load website design using struts

Nico,

Great! That is exactly what I'm looking for.Maybe I'll
have some hard time to setup a testing environment and
write some code to see what will happen.

Thanks a lot!

You could look at this :

http://c-jdbc.objectweb.org/

this intermediate JDBC driver allow you to cluster databases. Notice I never used it, 
use it at your own risk ;-)

question on heavy load website design using struts

2003-07-17 Thread guo yingshou
Hi,

I am sure that someone here must have worked on a
large website with heavy load using struts and I
wonder if you'll be kindly enough to give me some
suggestions in this occasion.

I am using tomcat+jboss as application server.I have
setup several tomcat_jboss instances in a cluster
environment and of course I use struts in my
application.HttpSession created in one instance will
get replicated across all members in the cluster.It's
just what I want.The problem is how should I connect
the app servers with the backend db server(s)? If I
use only one db instance,all app server can connect to
it without any problem,but here lies the bottleneck.I
want to use several db instances(preferrably
mysql).How can I do that?

Thanks in advance!

Guo Yingshou
