If you are unable to connect to your Paribus Discovery Control Database, this may be due to one of the following:

  • The SQL Server service on which the Control Database is located is not running. Start the SQL Server service.
  • The Control Database does not exist on the selected SQL Server. Create a Control Database on the designated server, or connect to the server that is hosting the required database (a Paribus Discovery Server Licence will be required for this server)
  • Maximum number of Paribus Control Database connections exceeded. Each Paribus Server Licence defines the maximum number of connections that can be made by any Paribus installation to a given SQL Server instance. Once this has been reached, no further connection can be made by Paribus to the given server. Either install a new Paribus Server Licence with an increased number of connections or disconnect from the SQL Server from one or more Paribus installations.
  • Paribus Discovery requires Microsoft Data Access Components 2.6 to run correctly. Make sure this is installed on the client machine.
