Questions and Answers
 When the JDBC creates connections through FCF/ONS why do we see 2 connections/details on the OS
level using netstat ( one with port 6200 and one server process 1521)?
 Can you explain how ONS works with the JDBC driver?
What happens if the ONS service is not running, will the client connection fail or will it still connect to the database (port 1521) and put a warning message on the application log?
