Thanx for answering Mark,
the need is to avoid attempting the connection if the Oracle instance appears to be unreachable. We're developing a panel pc app that has to connect to an Oracle server on demand (user touching screen and booking for canteen).
Problem is that the Oracle server happens to be on the other side of the mountains (and this is for real, no joke) and we've been warned about lack of connectivity/bandwidth on this connection.
So, to make a long story short, what i'm trying to do is avoid connection (and users waiting for a timeout to occur in front of pc) if Oracle is not tnspingable...
Other ideas are welcome, of course :)
