Well, chop me down with a herring!
I left for a meeting, came back and isolated the sql code to simplify it
and see if I break it down and figure it out. I was going to show a
co-worker the SQL problem and boom, it worked, and I have no idea why! But
the CL part of it is still giving me the SQLDescribeParam() failed error.
Aaron, I know you are one of the Open Source gurus around here, are there
any HowTo's to v8 on an iSeries, setting the correct paths and all that?
It took me a few days to figure out I had to get all the PTFs for 5733OPS
to actually have all the actual software, and then it kept running Node
v0.12, not v6, but I knew it was installed. So I ended up changing the
symbolic links manually. I just found the documentation that tells you to
run a script to do that today. :P
Thanks,
Kev

Thanks for the reply Aaron
It is version 6, the default install of 5733OPS plus PTFs, although I did
install v8 rpm and then "yum erase"d it. V8 would not run, probably due to
lib path issues and since I am new to all this, I decided it would be best
to stick with the defaults. But possibly the install/erase of v8 broke
things?
Below is the code. It's a basic copy/paste of what I found on the link
listed in the first email. except for the db credentials, etc.
var http = require('http');
var fs = require('fs');
var url = require('url');
var db = require('/QOpenSys/QIBM/ProdData/OPS/Node6/os400/db2i/lib/
db2a');
var xt = require('/QOpenSys/QIBM/ProdData/OPS/Node6/os400/xstoolkit/
lib/itoolkit');
var DBname = "*LOCAL";
var userId = "user";
var passwd = "pass";
var ip = "IPaddress";
var port = 8000;
var webserver = http.createServer((req,res) => {
var realPath = __dirname + url.parse(req.url).pathname;
fs.exists(realPath, (exists) => {
if(!exists){
var sql = url.parse(req.url, true).query.sql;
var cl = url.parse(req.url, true).query.cl;
if(sql && sql.length > 0) {
console.log("SQL statement : " + sql);
var dbconn = new db.dbconn();
dbconn.conn(DBname, userId, passwd); // Connect to the DB
var stmt = new db.dbstmt(dbconn);
stmt.exec(sql, (rs) => { // Query the statement
res.writeHead(200, {'Content-Type': 'text/plain'});
res.end(JSON.stringify(rs));
console.log(rs);
stmt.close();
dbconn.disconn();
dbconn.close();
});
}
if(cl && cl.length > 0) {
console.log("CL statement : " + cl);
var conn = new xt.iConn(DBname, userId, passwd);
conn.add(xt.iSh("system -i " + cl));
conn.run((rs) => {
res.writeHead(200, {'Content-Type': 'text/plain'});
res.end(xt.xmlToJson(rs)[0].data);
});
}
} else {
var file = fs.createReadStream(realPath);
res.writeHead(200, {'Content-Type':'text/html'});
file.on('data', res.write.bind(res));
file.on('close', res.end.bind(res));
file.on('error', (err) => {
res.writeHead(500, {'Content-Type':'text/plain'});
res.end("500 Internal Server Error");
});
}
});
});
webserver.listen(port, ip);
console.log('Server running at http://' + ip + ':' + port);

What version of Node.js?
Can you post your code so we know exactly which example you're talking
about?
FWIW, if you're using Node.js v6.x then I'd upgrade to Node.js v8.x and
work through issues with that version. https://github.com/nodejs/Rele

at not having much luck.
The SQL part of the script is connecting to the DB2 server, but any
* From library/db" results in an empty brackets []. If I send query"VALUES
current date", I do get [{"00001":"2018-03-29"}] back. If I put in badwatch
credentials, I do get auth errors, so it seems to be connecting to the
server.
The same queries work fine from STRSQL.
Also the CL part of the example just returns
Error: SQLSTATE=PAERR SQLCODE=-1 SQLDescribeParam() failed.
at Error (native)
I am new to nodejs, the plan was to find examples for the iSeries,
them work, then see how the work and start from there.problem
Also wondering if my other issue might have some relation to this
(see "Broken npm?" thread in OpenSource).--
Thanks
Kev
