| 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? |
