One the advantages of having an as/400 is that you only need one box. This box runs the application and the database. It's also very scalable, this one box, and it can support 1000's of users.

If you split the app server and the db server into two boxes then you have a bottleneck, i.e. the communication of data between these two boxes. So you have to take this into account when designing your application. And if you have lots of users you maybe have to put another windows web application into the mix. Making it all complicated and difficult to manage. Windows is not powerful enough to support a database and application server on one box. The as/400 is designed for this. There is no I/O bottleneck between the applications and the db.

As an addition to the Apache discussion, .Net applications will run
under Apache on Windows, so you can avoid setting up IIS. This is cool !

This is still probably a two-server scenario of Windows + i, however we
do the same a lot of the time with JSP's as well because performance of
JSP's on iSeries have not always been up to par. Running Tomcat on a
Windows box far outweighs the native iSeries performance.

On the CGI topic, RPG-CGI smokes, but it's harder to find developers
that know RPG+Web than it is to find .Net or JSP coders.

Apache comes pre-installed on 99% of all AS400 servers in my experience.
It runs "natively" as far as I am concerned as IBM has added their own
hooks outside of the base Apache HTTP server available from
www.apache.org. Note that it simply runs under subsystem QHTTPSVR on
the same hardware that your green screen users are on (i.e. QINTER).

And the Apache server is pretty each to configure for RPG+CGI. Here is
the config I use:

Listen *:8181

DocumentRoot /www/myrxs/htdocs

ScriptAliasMatch ^/MYRXS/(.*) /qsys.lib/MYRXS.lib/$1.pgm

allow from all
order allow,deny
options +ExecCGI

The one thing I believe to be lacking is a "RPG CGI best practices"
book/course that helps you skip past all the yuck stuff that many have
to figure out for themselves (i.e. how do you access tables outside of
the library your RPG CGI is running in?). Brad Stone you listenin' ?

Raul,

What if RPG is out of consideration?

Your point about .Net requiring two or more servers caught my eye and
made me wince. But.. if one must use something like Apache for their
environment/language to work, isn't that using two or more servers as

well?

Thanks,

Dave
