Node.js to DB2 (using ibm_db)

I've followed the instructions: https://www.ibm.com/developerworks/community/blogs/pd/entry/using_ibm_db2_from_node_js4?maxresults=15&page=0&lang=en for a 32-bit install of Ubuntu.

It seems to have installed correctly and I can run require('ibm_db'). Using the sample code provided (nodedb2test.js), no matter what database parameters I use I get the error:

node nodedb2test.js
Test program to access DB2 sample database
*** stack smashing detected ***: node terminated
Aborted (core dumped)

Heres the sample code:

/*require the ibm_db module*/

var ibmdb = require('ibm_db');
console.log("Test program to access DB2 sample database");

ibmdb.open("DRIVER={DB2};DATABASE=testdb;UID=username;PWD=password;HOSTNAME=localhost;port=3000", function(err, conn)

{
        if(err) {
            console.error("error: ", err.message);
           }

});

Also I looks the version of DB2 I need to connect to is version 6. I have installed BM Data Server Driver version 10.5, does this correspond to the version of DB2? It appears below v9.1 drivers are not available.

At time of writing this works for me.

C:\Development\Javascript>node -p "process.arch" x64

C:\Development\Javascript>node -p "process.platform" win32

C:\Development\Javascript>node -p "process.version" v14.17.5

C:\Development\Javascript>npm install ibm_db

var ibmdb = require("ibm_db");

const config = require("config");
const hostname = config.get("db2.hostname");
const username = config.get("db2.username");
const password = config.get("db2.password");

ibmdb.open("DRIVER={DB2};DATABASE=bludb;HOSTNAME=" + hostname + ";UID=" + username + ";PWD=" + password + ";PORT=31198;PROTOCOL=TCPIP;SECURITY=SSL", function (err, conn){

  if (err) return console.log(err);

  conn.query("SELECT * FROM orders", function (err, data) {

    if (err) console.log(err);

    console.log(data);

    conn.close(function () {
      console.log('done');
    });

  });

});

We can use ibm_db without installing IBM Data Server Driver Package too. ibm_db internally uses DB2 V10.5FP5 ODBC/CLI driver to talk to DB2 server. Please share the platform info and OS version where you have installed ibm_db. In june'14, ibm_db was supported on Linuxppc, AIX and zLinux platforms, but latest release is supporting. If latest driver is not working for you, please open an issue on github.com/ibmdb/node-ibm_db/issues/new . Thanks.
