Troubleshooting
Problem
User launches the Cognos Connection website inside Internet Explorer (for example http://servername/ibmcognos). User clicks "Consolidate my Financial Information" (in older Controller versions, this icon is simply labeled 'Cognos Controller'. A blank screen (white screen) appears, but the Controller client does not appear to start launching on the screen.
Symptom
Depending on the environment (and how you chose to launch Controller), the end user will see slightly different symptoms. For example, you may find that one the following descriptions fits the problem best:
- The Controller client fails to start - it does not appear to launch anything (nothing happens). There is no error message
- Internet Explorer screen changes to a white page (blank screen).
- The only thing visible is either
http://servername/ibmcognos/cgi-bin/cognos.cgi
orhttp://servername/ibmcognos/cgi-bin/cognosisapi.dll
(depending on how the gateway is configured)
