I want to debug a web request which calls a c++ executable built
using
AIX/UNIX. I am having IBM AIX Server. How to start this ?

Thanks & Regards
JK

What does "debug a web request" mean? Or do you have to debug
the the program written in C++ that gets invoked as a result of
the "web request"? In the later case what makes that different
from debugging any other program (except that you may have to
set up a few environment variables)?

If I understand what you're asking, the best way is probably to create
a test harness that can launch the C++ executable the same way the web
server does (path, permissions, environment, and so on) but under a
debugger.

Hi All,
Thanks for the response.

I will explain you, it is something like this.

GUI - Web Server requests
Middleware - c++ executables
backend - D/B respository

so when the web reqeust is give, say want to view then the request
hits the c++ exes, created in unix~ AIX 5.1 and the request is
processed, sent to D/B.

Response is again processed by c++ exes in AIX 5.1 and send to web
page as output.

Now how to launch the same under debugger. I am going through the
documentation fo adb debugger, i am unable to move further.

I also wanted to know if we have to use any visual age c++ debugger or
xlC compiler.

please do help.

Thanks & Regards
JK

Co you have a C++ CGI program. Just wrap it in a shell that sets up the
CGI environment variables and call it. I assume you have some unit
tests for the code? If not, why not?
