2. Change controller port and PCE port in /opt/flowintegrator/tomcat/webapps/ROOT/WEB-INF/classes/conf/application.properties # Controller listener port number

   coss.controller.port = 20047

   # Controller connection timeout in milliseconds

   coss.controller.connectionTimeout = 60000

   # Default PCE configuration notification changes listener port number

   coss.pce.port = 20048

   # Default PCE configuration notification changes host

   coss.pce.host = 127.0.0.1
