Verifying startupTo verify that the
Network Server is
currently running, use the ping command.Network Serververifying startup
You can use the ping command in the following
ways:
You can use the script NetworkServerControl.bat for
Windows systems or NetworkServerControl for UNIX systems
with the ping command. For example:NetworkServerControl ping [-h <hostname>;] [-p <portnumber>]You can use the NetworkServerControl ping
command:java org.apache.derby.drda.NetworkServerControl
ping [-h <hostname>] [-p <portnumber>]You can use the NetworkServerControl API to verify startup from
within a Java application:ping(); The following example uses a method to verify startup. It will try
to verify for the specified number of seconds:
private static boolean isServerStarted(NetworkServerControl server, int ntries) {
for (int i = 1; i <= ntries; i ++) {
try {
Thread.sleep(500);
server.ping();
return true;
} catch (Exception e) {
if (i == ntries) {
return false;
}
}
}
return false;
