we have a project with Node.js that use the ibm_db to connect to the DB2/AS400.
The problem is that it returns the following error:
[SERVER] { Error: [IBM][CLI Driver] SQL1598N An attempt to connect to the database server failed because of a licensing problem. SQLSTATE=42968
[SERVER]
[SERVER] errors: [],
[SERVER] error: '[node-odbc] SQL_ERROR',
[SERVER] message: '[IBM][CLI Driver] SQL1598N An attempt to connect to the database server failed because of a licensing problem. SQLSTATE=42968\r\n',
[SERVER] state: '42968' }
there Is an alternative way to connect to AS400, from node, js that does not require a license?
This is the code we use for the connection:
"use strict";
var models = require("../../models/index");
var express = require("express");
var db2Route = express.Router();
const ibmdb = require("ibm_db");
//import ibm_db
const opts = [
'DRIVER={IBM DB2 CLI DRIVER}',
'DATABASE=*****',
'PROTOCOL=TCPIP',
'HOSTNAME=*****',
'PORT=446',
'UID=*****',
'PWD=*****',
'DBQ=,*USRLIBL'
];
db2Route.route("/").post((req, res) => {
ibmdb.open(opts.join(';'), (err, conn) => {
if (err) return console.log(err);
conn.query("Select * from TBFR0F" ,(err, data) =>{
if (err) console.log(err);
else console.log(data);
conn.close(() => console.log('done'));
});
});
});

Reset to default 2If you have access (sorry I don't know how this is set up) you can use JDBC or ODBC. You can utilize the open source jt400 toolkit with Java (through Node.js) or you can use the node-jt400 package which wraps SOME OF the jt400 java library into node bindings.
const jt400 = require('node-jt400');
const { connect, pool, Connection, TransactionFun, BaseConnection } = jt400;
const jt400config = {
host: 'POWER7',
user: username,
password: password,
"translate binary": "true" // might be important for you...
};
const pool2 = await connect(jt400config);
const query = (pool,query) => new Promise((res, rej) => {
pool
.query(query)
.then((results) => res(results))
.catch((err) => rej(err));
});
let queryResults = await query(pool2,`
SELECT * FROM (
SELECT
asdf,
asdf2,
CONCAT(CONCAT(asdf3,asdf4),asdf5) AS asdf6
FROM ${library}.${table}
) as A
WHERE asdf6= '${myAsfd6}'
`);
The ibm_db package uses Db2 Connect drivers under the covers. When connecting to IBM i, Db2 Connect requires a license as you have found.
Instead of using ibm_db, the remended way to connect from node is with node-odbc and the IBM i Access ODBC driver. This requires no license and works across Windows, Linux, and on IBM i in PASE. We have built our LoopBack and Sequelize support on top of this package.
Does this article from Aaron Bartell (who is v expert on the node.js / IBM i bo) help?
https://www.mcpressonline./analytics-cognitive/db2/techtip-node-js-on-linux-with-jdbc-connection-to-db2-for-i
He gives several options though none simply provides an alternative, free of charge, driver. He provides a worked example for his jdbc option.
