how classic cache servers stay alive

Main server threads simply keep running, usually blocked in socket.accept() or rmi server mode. This thread below is responsible to shut down JVM at 23:00. As another control, there’s also an Autosys stop job to shut down the JVM.

 

public void run () {

      if (hour < 1 || hour > 23) {

            return;

      }

      while (true) {

            try {

                  Thread.sleep (10 * 60 * 1000);

                  // set up hour from current system system

                  if (hour < 1 || hour > 23) {

                        System.exit (0);

                  }

            } catch (Exception ex) {} // do nothing

      }

}
