Re: query via jdbc thin to a datbase in DMZ

instead of a ping, try to male a telnet on the used port, ususally 1521. does it connect?

dont expect telnet to do something usefull (unless you are a native sql8net speaker ;-), but you should get

oracle_at_xxx:/ > telnet xxx 1521
Trying 192.168.2.116...
Connected to xxx.
Escape character is '^]'.

rather than

oracle_at_xxx:/ > telnet xxx 1500
Trying 192.168.2.116...
telnet: connect to address 192.168.2.116: Connection refused
