Node Js to Oracle Connection with TNS connection string

user11148886

Hi ,

I am trying to connection to a remote Oracle server from Node Js code . I am trying to use TNS connection string instead of conventional configuration connection string. I am using following but getting "ORA-01017: invalid username/password; logon denied" error. Could anyone help me with this error? Following is my code for connection

var express = require('express');

var object_to_xml = require('object-to-xml');

var router = express.Router();

var db;

var  dataQuery= "select * from movie";

router.use('/', function(req, res, next) {

  var connString = "(DESCRIPTION =(LOAD_BALANCE = ON)(FAILOVER = ON)(ADDRESS =(PROTOCOL = TCP)(HOST = server1)(PORT = 1521))(ADDRESS = (PROTOCOL = TCP)(HOST = server2)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=XE)(FAILOVER_MODE=(TYPE=SELECT)(METHOD = BASIC))))";

  var config = { "tns": connString,"user": "scott", "password": "tiger" };

  db = require('oracledb');

  db.outFormat = db.OBJECT;

  console.log(config);

  db.getConnection( config,function(err, connection)

  {

  if (err) {

  console.error(err.message);

  return;

  }

  connection.execute( dataQuery, function(err, results)

  {

  if (err) {

  console.error(err.message);

  return;

  }

  res.send(object_to_xml(results));

  });

  });

});

module.exports = router;

but when I am trying to connect to any of the server mentioned in the host  from SQLDeveloper then I am able to connect correctly.

Change tns to connectString.  See https://github.com/oracle/node-oracledb/blob/master/doc/api.md#connectionhandling

You are probably connecting to whatever your shell has set as the default with ORACLE_SID
