Answer 1

You can create a separate thread to monitor the DB connection. While starting the server invoke that thread. If db connection failed means send mail from that threat.

Example :

        boolean isDBConnected,isServerConnected;
        while(true){                
            isDBConnected=checkDBConnection();
            isServerConnected=checkServerStatus();
            if(isDBConnected && isServerConnected){
                Thread.sleep(100);
            }else{
                sendMail();
                break;
            }
        }
