We are having difficulty communicating with the Orion server

When trying to access the Recommendations page after upgrading to VMan RC2, the following error is displayed:

We are having difficulty communicating with the Orion server.

  • VIM 7.0.0
  • All VMan versions


Previous version (RC1 or Beta) of Recommendations damaged the database.


Note: Take a backup of your database.

  1. Stop all Orion services using Orion Service Manager.
  2. Using SQL Management Studio login to the database and drop all tables which starting with 'dbo.RE_'. (RE_Actions, RE_BathActions, RE_Recommendations, etc.)
  3. Run Configuration Wizard with Database option - to repair the database.
  4. Wait a while and then check Recommendations.
