Cause
There are several known causes for similar errors.
- TIP: See separate IBM Technote #2011388 for more potential causes.
This Technote specifically relates to the scenario where the cause is invalid cache files inside client device's Internet Explorer.
Environment
Problem does not affect all client devices.
Example:
In one real-life example:
- The server had recently been upgraded from Controller 10.1.1 to 10.2.
- The problem only appeared when running the Controller client directly on the Controller application server (Windows 2012 R2) itself. For example, if you used a Windows 7 client device (connecting to the same application server) then the reports worked OK.
Diagnosing The Problem
In one real-life example, the server had recently been upgraded from Controller 10.1.1 to 10.2. However, when the user launches Cognos Connection (http://servername/ibmcognos) the 'splashscreen' still showed Cognos 10.1.1 BI being installed/used.
Resolving The Problem
Fix:
Modify the 'bad' user's Internet Explorer to re-check all of its cache files.
- Specifically Modify the setting 'Check for newer versions of stored pages' from the default ('Automatically') to 'Every time I visit the webpage'
Steps:
The following steps are based on IE11:
1. Launch Internet Explorer
2. Click "Tools - Internet Options"
3. Inside the tab 'General' click 'Settings'
4. Modify the setting 'Check for newer versions of stored pages' from the default ('Automatically') to 'Every time I visit the webpage':
Workaround:
Do not use Controller on the affected 'bad' device (e.g. Controller application server). Instead, run the Controller client from a different client device (e.g. end user's PC).
