Troubleshooting
Problem
In a Report View proceeding to set the values for the prompt receive a prompt selection screen, make selection, chose Next and the screen freezes.
Symptom
Customer is using Oracle Access Manger with WSSO agent deployed into IIS.
Cause
Cognos URL Rewrite rule 'Event Studio' sends a secondary request to the web server. Oracle WSSO agent does not deal with secondary requests properly.
Diagnosing The Problem
Capture Fiddler trace while reproducing the issue. Java Script .js files from /bi/prompting are not returned by the web server, HTTP code 504 is returned
Resolving The Problem
1. Navigate to the webcontent\bi folder in the Cognos Analytics Gateway installation
2. Open the web.config file for editing
3. Replace the XML element having name="Event Studio" with the following:
<rule name="Event Studio" stopProcessing="true">
<match url="^(ags|cr1|prompting|ccl|c
<conditions logicalGrouping="MatchAll" trackAllCaptures="false">
<add input="{HTTP_REFERER}" pattern="v1/disp" />
<add input="{HTTP_REFERER}" pattern="v1/disp" />
<add input="{HTTP_REFERER}" pattern="v1/disp" />
<add input="{HTTP_REFERER}" pattern="v1/disp" />
</condition
<action type="Rewrite" url="http://dispatcher_host:dispatcher_port/{R:0}" />
</rule>
if you're using a server farm, use http://farm_name/{R:0} instead
4. Restart IIS
