Thread: connection timeout?
Hi all,
I executed following test in a classical scenario involving an application on a PC connected to a DB Server where postgres is running:
- I disconnected network cable between PC and DB server
- I started the application on PC
The application remains blocked on
DriverManager::getConnection
method invocation.
Is it a timeout issue?
If so, how can I set this timeout?
Thanks in advance,
Roberto.

Currently you can't, mostly because it hasn't been a big enough issue for anyone to step forward and implement. When implemented I'd expect it would be set via a URL parameter. The Java socket primitives makes it quite hard to do timeouts on connect anyway. Either you have to use NIO (doesn't exist until 1.4, would be an invasive change) or Socket.connect() (doesn't exist until 1.4). So you're out of luck under 1.3, and the driver will have to do conditional compilation to use 1.4-specific code as it needs to build under 1.3. -O
