Myrna van Lunteren commented on DERBY-3211:
-------------------------------------------
Coincidentally, I wrote a silly getAlternatePort() method for the
TestConfiguration class.
Maybe some review of the method will be useful here - it'll take a bit longer
before I have the test I'm working on (testProperties.java) converted. This is
what I have so far:
public int getAlternativePort() throws SQLException {
Exception failException = null;
// start with the default port + 1
// there may be a smarter way to get the starting point...
int possiblePort = getPort();
if (!(possiblePort > 0))
possiblePort = 1528;
else
possiblePort = getPort() + 1;
try {
boolean portOK = false;
while (!portOK) {
// check for first one in use
NetworkServerControl networkServer =
new
NetworkServerControl(InetAddress.getByName("localhost"), possiblePort);
// Ping and wait for the network server to reply
boolean started = false;
try {
networkServer.ping();
// If ping throws no exception the server is running
started = true;
} catch(Exception e) {
failException = e;
}
// Check if we got a reply on ping
if (!started) {
// we'll assume we can use this port.
// If there was some other problem with the pinging, it'll
// become clear when someone attempts to use the port
portOK = true;
}
else { // this port's in use.
possiblePort = possiblePort + 1;
}
}
} catch (Exception e) {
SQLException se = new SQLException("Error pinging network server");
se.initCause(failException);
throw se;
}
return possiblePort;
}
