Hi Epyonne,
you not only forgot to change the subject line, but you hijacked a 
thread, which means that your new thread and the original thread will 
get all jumbled together in the archives and it makes it a pain to 
follow. You can get your own thread just by composing a new msg instead 
of 'replying to'.

By the way re: connections, tomcat will on a low level not see any 
difference between your own connection handling and the tomcat 
connection pool, since both are java implementations. It will depend 
more on your database connection limit which I think by default in 
Oracle is 200.

the first thing to check is, if you're using windows workstation, it has a limit of 10 
inbound connnections for everything. so you might want to double check that first.
 
if you're oracle is hosted on a windows worstation, it will be limited to 10 
connections in the pool. Atleast that is my experience when I was doing benchmarks on 
my workstation for the performance article. hope that helps.

We have the option to use Oracle 9i AS because we have the enterprise
license. I am just wondering if it will be an overkill when a Tomcat
standalone can do the job. Not to mention I don't have to redeploy my
servlet application if Tomcat can handle the load (i.e. 400-500 concurrent
users).

Any help will be very much appreciated.

Generally speaking the limit is a Java heap size.
AFAIK:Tomcat do not have restriction on the servlet ojects.

If you don't using any connection pooling you will have so many instances as you 
created.
But if you are talking about 400-500 concurent users, you should consider pooling as 
must have.
Pool will take care of connection time out, and the most important you are not going 
to produce a lot of garbage.

As practice shown, nicely written application can handle hundreds of concurent users 
on a regular PC with IDE hard.
