SOLVED: Linux RH 5, Cognos10, cognoscgi.conf causes cognos.cgi to fail

[prikala]

The problem below is now solved. Publicly complaining seems to help, solution comes to mind immediately...
Unlike I said, contents do matter. The trick is NOT to use cognoscgi.conf.sample as a template and not to test with an empty config file.
Everything works when I create the config from scratch.

(Update about the 404 I mentioned: It is indeed returned by dispatcher: http://www-01.ibm.com/support/docview.wss?uid=swg21654200)

---------------------------------------------------


Hi all!

I was trying to debug a possible problem with cognos.cgi (intermittent HTTP status 404).
When I created the cognoscgi.conf file to enable debugging,
cognos.cgi started failing.

When I run it directly from command line to see what is the problem, it says:
  terminate called after throwing an instance of 'NoSuchElementExceptionST'

Both 10.1 and 10.2.1.1 behave like this. 8.4.1 is ok.

So the existence of config file causes cognos.cgi to crash.
Contents of the file are irrelevant.

Any ideas on how to enable gw trace without conoscgi.conf?

(Opinions about cognos.cgi itself returning HTTP 404 are also welcome)



Here is an example, first without cognoscgi.conf and then with empty file.
