Does anyone know why I am receiving this error message? I am successfully able to connect to this database using Navicat or SqlDeveloper using the exact same parameters. I am also successfully able to connect to a different database using different connection string parameters.

var sys = require('sys');
var oracle = require('oracle');

var connectData = {
hostname: "11.6.309.144",
port: 1521,
database: "FF234J", // System ID (SID)
password: "BLAHPASSWORD"

exports.dumpData = function (req, res) {
var sql = "SELECT * from BEATS where rownum < 3";

oracle.connect(connectData, function(err, connection) {
if (err) { console.log("Error connecting to db:", err); return; }
connection.execute(sql, [], function(err, results) {
if (err) { console.log("Error executing query:", err); return; }


The value for the database field needs to be the service_name, not SID. Basically the listener on the database server does not know about the service named "FF234J" in your example. You can get a list of services that your listener knows about by logging on to the database server and issuing the "lsnrctl status" command
