Cause
There are several possible causes for similar error messages.
This Technote specifically relate to the scenario where the cause is an invalid/incorrect System Variable "CCR_JAVA_Home" on the Controller application server, for example: 
- TIP: For more examples, see separate IBM Technote #478825 .
This Technote specifically relate to the scenario where the cause is an invalid/incorrect System Variable "CCR_JAVA_Home" on the Controller application server, for example:
Diagnosing The Problem
On the Controller application server, there are no entries created inside the 'ccr.log' file
- TIP: By default, this is located here: C:\Program Files\ibm\cognos\ccr_64\log
Resolving The Problem
Fix:
For almost all environments, it is not necessary to have a System Variable 'CCR_JAVA_Home'
- Therefore simply delete it.
Steps:
1. Logon to the Controller application server as an administrator
2. Inside Windows Explorer, right-click on 'This PC' and choose 'Properties'
3. Click Advanced System Settings
4. Inside the tab "Advanced" click "Environment Variables"
5. Inside the section "System Variables" delete the entry for "CCR_JAVA_Home":
Workaround:
In some (rare) environments, it is necessary to use 'CCR_JAVA_Home'. In this case, you must:
- Ensure that the System variable CCR_JAVA_Home is configured correctly
- Afterwards, restart the Windows services "IBM Cognos Controller Java Proxy".
Steps:
1. Logon to the Controller application server as an administrator
2. Launch Windows Explorer, and right-click on "Computer"
3. Choose "Properties"
4. Choose "Advanced System Settings"
5. Inside the tab "Advanced" click "Environment Variables"
6. Inside the section "System Variables" check that there is an entry for "CCR_JAVA_Home"
7. Check that the 'value' is correct (no typos).
Examples:
- For Controller 10.4.2 (installed in the default location) this value should be: C:\Program Files\ibm\cognos\ccr_64\bin64\jre\8.0
- For Controller 10.1.1 (installed in the default location) this value should be: C:\Program Files (x86)\IBM\java60\jre
8. Restart the Windows services "IBM Cognos Controller Java Proxy".
