Symptom 1

• When attempting to access OnCommand Insight Data Warhouse's web interface, the user will see an IBM WebSphere Application Server notice: "Context Root Not Found".

Symptom 2

• When attempting to start IBM Cognos manually via IBM Cognos Configuration, the operation will fail with the following.

[Launching a JVM using 'Maximum memory in MB']
Successfully launched a test JVM with the memory setting of '4096'. Note that this does not guarantee that the IBM Cogn os service will start and run successfully.

• To see which JVM options are based on this setting, view ibmcognos_location/bin64/bootstrap_wlp_<OS>.xml and see your JVM documentation for an explanation of those options.

[Archive Local File System Root]
Since the value is empty, the feature is disabled. There is nothing to test.
