Re: Question about QZSRCGI.

[Scott Klement <web400@xxxxxxxxxxxxxxxx>]

Hi Terry,

Typically you'd set up your httpd.conf with something like this:

<Location /diva>
    SetEnv QIBM_CGI_LIBRARY_LIST "QGPL;MYFILESA;MYPGMSA;QTEMP"
</Location>
<Location /divb>
    SetEnv QIBM_CGI_LIBRARY_LIST "QGPL;MYFILESB;MYPGMSB;QTEMP"
</Location>

When the user connects to a URL as http://example.com/diva, he'll have 
MYFILESA and MYPGMSA in his library list.   When the URL ends in /divb, 
it'll be MYFILESB and MYPGMSB instead.

It may end up using the same CGI instance -- but the library list of the 
instance will be changed before the CGI program is called.   This means 
that the program must close it's files and re-open them based on this 
URL changing, otherwise it could retain the previously opened files 
which might be in the wrong library.   Not sure if you normally keep 
files open or closed, so this might or might not apply to you.

You may want to also include directives like this:

<Location /divb>
   Require valid-user
   PasswdFile %%SYSTEM%%
   UserID %%CLIENT%%
   AuthType Basic
   AuthName "Div B Sign On"
   SetEnv QIBM_CGI_LIBRARY_LIST "QGPL;MYFILESB;MYPGMSB;QTEMP"
</Location>

The Auth stuff means that the user needs to sign on with their System i 
userid & password.   The "UserID %%CLIENT%%" tells the system that the 
jobs run run with the signed on user's authority -- which also has the 
side-effect that a separate CGI instance (which is what I assume you 
mean by QZSRCGI instance) is created for each user who signs on. 
Different userids will get different instances.

If your users don't use multiple divisions, this may help you leave the 
files open if you want them open, or at least reduce the frequency that 
you have to open or close them.

There are environment variables that are passed to your program that can 
be used to determine which instance you're currently in (in case your 
program needs to know that in order to open/close files for example).  I 
don't remember what they are off the top of my head, but if you dump the 
variables for the CGI instance, you should be able to see which ones 
make a difference.
