Re: Apache config -- WEB400

Here is the link that you sent.
https://fieldexit.com/forum/display?threadid=522 I do see that it is 4
years old so it is probably obsolete. :)

So the library list is in a file stored on the IBM i, correct? How does
your process know which file to read to get the library list if there are
multiple environments (different libls)? It seems like I will need to add
another field in my json to tell it that. It also seems like all of the
push and pop would create a chunk of overhead. When I get the real app
working (I'm still playing with concept at this point so I only have a
couple), there are actually about 25+ libraries in the library list. That
means 50+ push/pop for every call. Or am I still missing something with
what you are doing?

Does your process do an HTTP POST or am I trying to make my process work
like yours and they are apples and oranges.

And my apologies if I sounded short with any of my comments / questions. I
feel like I am trying to tread water wearing a concrete overcoat and it is
getting frustrating.

Subject: Re: [WEB400] Apache config

What link did I send you? I recall sending someone a generic Apache config
posted at Fieldexit.com... or maybe an IBM link that may have had it.

Here's how I do it.

pushLib('datalib');
//do eRPG stuff
popLib('datalib');

I wrote pushLib and popLib years ago. Inside of it there also are functions
that can set a library list using a job description (I don't think attaching
a job description to QTMHHTTP or QTMHHTP1 will change their functioning
library list... and it's also not easily changed each program run).

Control files are pretty simple...

sequence
library

Read through it by sequence and for each library pushLib()... then at the
end popLib(). You can even make a nice ILE function to do this.

I was sharing how I have done things for over 25 years with great success.
Sorry if it confused you.

I am so totally confused by what I am being told.

I am trying to run an Angular / javascript app in the browser that
does an HTTP / Apache connection to get the data. The program that it
is running
(HTTPDATA) is a generic "SQL server" program that can take any SQL
request and process it. As for the Angular / javascript part, it is
unable to touch anything on the PC.

Now to this response.

You said that you never used those environment variables to set the
libl yet that is what was in the link that you sent me for how to
configure apache.
I assumed that was what I needed to use.

So to do it differently, you suggest a control file with a jobd or
library list. Where is this control file stored? I'm guessing that
it has to be on the IBM i somewhere because again, I can't access the
PC with my app.

For the jobd part of your response, I am not starting a job (maybe it
is auto started behind the scenes when I connect) so how do I specify
a jobd for a job that I am not submitting?

I am really struggling to find good documentation and I know part of
that is because I don't fully understand what I am trying to do and
much of what I read does not make sense. When Brad provided the link
for the apache configuration script file, I spent a ton of time trying
to figure out where it was so I could edit it. I finally noticed that
I can edit the config in the HTTPAdmin page. I still have not clue
where it put the thing.

Is there somewhere that I can get "step by step instructions for dummies"
on
the best way to do this stuff?

I never used those environment variables to set the libl. I use my
push and pop libl functions. Much more convenient and no stopping and
starting the instance if it changes.

A simple control file to point to a job description (heaven forbid
those are
used!) or just a simple library list file. Easily updatable for the
next time the program runs.

Shouldn't the OP be fine using those settings but specify the same
program in each? It seems he has only to retrieve the value of the
QIBM_CGI_LIBRARY_LIST environment variable and set the LIBL from it?
The docs say "The internal environment variables set by this
directive are set after most early request processing directives are
run", so it probably depends on timing.

I speak from long-time-ago working with this stuff, so please
forgive if I'm as clueless as ever!

Yes, but you'd need to control the library list in your program

itself.

What I do is set an environment variable to prod or test, retrieve
it,

and

set the library list dependent on that at the beginning of the

program.

I

have some push and pop lib functions I use for that.

But in your case I don't see an issue.. I would personally prefer
2

apache

instances, one for prod and one for test/dev as well as separate
libraries. Then I would run the test one on a different port
(like
8080

or

8443).

I am using the alias to control the library list between my prod

each library. Is there a way to configure this so both aliases
call the same program such as /qsys.lib/httpcommon.lib/httpdata.pgm?
