var connectData = {

    hostname: "localhost",

    port: 1521,

    database: "xe", // System ID (SID)

    user: "oracle",

    password: "oracle"

}

oracle.connect(connectData, function(err, connection) {

    if (err) { console.log("Error connecting to db:", err); return; }

    connection.execute("SELECT systimestamp FROM dual", [], function(err, results) {

        if (err) { console.log("Error executing query:", err); return; }

        console.log(results);

        connection.close(); // call only when query is finished executing

    });

});
