Problem – In Sitecore versions 8.1 and above Sitecore analytics is not working and Sitecore logs show below information
INFO **********************************************************************
INFO xDB is disabled.
INFO
INFO Tracking is enabled.
INFO
INFO Missing valid xDB license.
INFO **********************************************************************
Cause - Sitecore added an additional key to its license file. Sitecore 8.1 requires this new key to enable xDB features. Following could be the reason:
- Your license does not contain this new key.
- Your license does not allow xDB features.
Solution
Sitecore 8.1 now requires a license with the “Sitecore.xDB.base” key to enable all features of the Experience Platform. If your license file does not contain this key, Sitecore will default to Experience Management (CMS-only) mode. Any customers or partners with a license to Experience Platform should contact their account manager or login to SPN if they are missing this key.
