Re: Question on QTEMP and CGI Jobs

Richard

I use several AJAX calls when i launch my portal.

First the main accordion that is generated based on user rules.

Each of these accordion tabs is an object that points back to a service
that populates them using a simple JSON structure also based on
user rules.

This means that user A dosn't sees the same menues as user B since
he only sees functions he is allowed to process.

While this process i running the actual tree structure are build using
a Tree Traversal algoritm that also use recursive calls og sub-procedures.

And every for evry function there are issued a request in a tabel that
consist of the session random number, the request random number,
the CGI program name that all has to match to run the function and
the request may also hold server side parameters.

When a function is called the process starts again, request are made
for each service the function uses an server side parameters are
replicated down through the chain.

Since it is totally server controlled there are no cookies and the method
has also been SOX audited and by EU to meet the standards for protecting
systems that handles personal sensitive information where the penalty for
not doing that is up to 20 million EURO or, if you are a big international
company, 25% of the company global turnover. Nice guy's them in the
EU commission and i'm afraid that your cookie strategy down bring you
far in that line of business since they are regarded as unsafe ;-(

Richard,

Using AJAX or even SSI can result in a single page making many multiple
requests for one single page displayed.

I personally do the same thing with web page design as with ILE. If it
will be displayed on more than one page (or on every page, for example a
user's signon status) it because an AJAX or SSI call.

So it's really no problem for one page when displayed loads data from 5
different places. Of course, each of those "calls/reuests" will use it's
first available job.

Thanks for the education on Ajax also in response to my simple question

on

QTEMP.

If the Apache server is set to single-thread then I imagine these Ajax
requests would be stacked and each would wait for the thread to service

it

and could possibly time out.

Out of curiousity: For application efficiency why are you making 5 Ajax
calls at once ?

I tend to try to simplify any apps I write to minimize the back and forth
interaction to the back end. I try not to get data until needed and
sometimes cache data app side in a database or local data variables.

I've been writing apps for devices and try to minimize network impact so

I

guess you could say I'm more passive than aggressive :-)

Kevin

well, it may be understod that they share QTEMP since a call to PGMA from
user 1 and thereafter call to PGMB from user 2 running under the same
QZSRCGI shares the same QTEMP that belongs to the QZSRCGI and not PGMA or
PGMB.

PS - I don't think you uses AJAX as agressivly as I, if you fires 4-5
unnested AJAX calls from the browser at the same time it will result in

4-5

QZSRCGI jobs handling the requests, in other word they aren't queued to

the

same QZSRCGI job.

Remember that persistence CGI was written way before AJAX where AJAX may
run many independend sockets to the server at the same time.

So the even shorter answer to this question "Would there be any way
for two CGI calls at the same time to overlap the QTEMP libs ?"
is
"No!"
