  9. To run the newly attached data set, first setup your Virtuoso environment 

    [root@domU-12-31-39-00-00-61 ~]# cd /opt/virtuoso
[root@domU-12-31-39-00-00-61 virtuoso]# . ./virtuoso-environment.sh

  10. Run the "virtuoso-start.sh" script to start the Virtuoso server containing the attached data set 

    [root@domU-12-31-39-00-00-61 ~]# virtuoso-start.sh bbc
Starting Virtuoso instance in [bbc]
[root@domU-12-31-39-00-00-61 ~]#

  11. Note the Virtuoso Server "dba" user's password is set to the default of "dba" for the dataset, it is recommended this be changed to a suitably secure password using the "System Admin -> User Accounts" tab of the Virtuoso Conductor (http://ec2-ami-public-dns-cname/conductor).

  12. The Virtuoso hosted data set can now be explored using the SPARQL or Facet Browser web service endpoints.
