Open /usr/local/unravel/etc/unravel.properties and search for oozie.server.url. If you don't find it, add it. Set it to your Oozie_host, where Oozie_host is the fully qualified domain name or IP address, for example, http://host.mycompany.com:11000/oozie.

oozie.server.url=Oozie_host

Restart unravel_os3 service. You can now monitor your Oozie workflows.
