Just as a question
How do you all manage state in the HTTP stateless environment? What is
state?
Happy new year

Yes I guess that is the concern. In a stateless environment I can have, say,
10 threads/jobs managing 300 concurrent sessions. In a stateful environment
I would have 300 threads/jobs. Is it a problem? I am not sure. With a 1000
concurrent sessions, is it just as efficient?

I think the concern is that stateful connections take up more resources.
Where a stateful environment requires one job per client, a stateless
environment can service many clients per job.
That being said, the IBM i platform is a good choice for a stateful
environment because of the way resources are managed.

I have always steered clear of persistent CGI because of a fear that it will
not scale as well as a standard stateless environment. Is this fear
justified? I have never had the opportunity to put it to the test.

There is nothing particularly special about stateful connections. InIceBreak. It is a feature that keeps track of your browser session and sends
traditional CGI processing this is known as persistent CGI, and has been
around since about 1998. Not only that, it's a built-in capability of
the IBM i that has been around for nearly as long on the IBM Apache
server. As far as I know, it goes back to V5R1 or V5R2, maybe further.
That's a decade or so. And with IBM, you control it by session, not by
server, so you can have persistent or non-persistent sessions on the
same server.
Also, this is a fundamental capability of WebSphere. Via the Java
toolkit you can have both persistent and non-persistent connections and
in fact, if you needed to you could have both persistent and
non-persistent connections in the same session! EGL supports this
capability out of the box; when you define a program (RPG, COBOL,
whatever) to be called you define whether it is stateful or stateless.
So you can have both stateful and stateless connections in the same
session! Stateful connections each have a persistent job, with
overrides and ODPs and a QTEMP - the job is named QZRCSRVS and runs in
QUSRWRK.
So, it's nice that IceBreak has this, but it's really not unique to the
tool.
Happy New Year!

P.S. For debugging, you might want to look into Service Entry Points.
It makes debugging web programs a breeze, even in non-persistent CGI!
Hi Kevin
"task switch feature"! This feature is a feature which is special in
request on to an isolated job native under OS/400. This means that your
programs can remain open with file pointers, variables etc. It also means
that you might use the QTEMP to something practical - again. Further, you
can work with the job through normal OS/400 interface such as WRKACTJOB. It
also means that with this technique can debug programs without having to
think about other jobs and sessions.
