Re: PASE for i ended for signal 6, error code 1. -- MIDRANGE-L

Peter,

Signal 6 is SIGTERM -- the "terminate" signal. This normally occurs when someone ends a job, either by using the Unix "kill" command, or running ENDJOB OPTION(*CNTRLD)

If nothing on your system is ending the job this way, then perhaps the software is ending itself? Sometimes programs detect a problem and raise a signal to terminate themselves.

As Kevin pointed out, using QP2SHELL is not reliable unless you spawn a new job and connect pipes to it to handle stdio descriptors. This is because QP2SHELL will run things in the same job, which is not how Unix code works -- Unix code would run each program in a separate process (the Unix equivalent of an IBM i job) and connect them with pipes.

If you try to run your program in the same job using the ILE C stdio support, it may or may not work, depending on whether the program is expecting multiple threads/jobs to be able to access the I/O simultaneously.

It has been known to cause all sorts of nasty hard to troubleshoot problems, though, so if you're in doubt, either spawn a job connected with pipes, or use the STRQSH/QSH command which will do that for you.

Kevin,

I normally use QP2SHELL so that the process runs in the same job to prevent starting copious jobs when the process is repeated frequently.
QSH starts a new job for each process.

I'd recommend using QSH for batch processing of Node.js applications.
QP2SHELL does not set up a proper environment, especially around file descriptors that can cause issues with Node.js applications.

For interactive applications, SSH (or in a pinch QP2TERM) is still the recommended environment.

I have a node.js script that runs fine when executed via the QSH

command.

But when executed via QP2SHELL or QP2SHELL2 it dies with the CPFB9C6
- PASE for i ended for signal 6, error code 1.

Here is the node.js script. It simply performs an HTTPS GET via a
forward proxy and writes the response to a flat file.

// ADDENVVAR ENVVAR(QIBM_MULTI_THREADED) VALUE(Y) is required before
running this script to avoid signal 5.
// To run enter the following command QSH CMD('node /home/pjctest/
node/proxyTest2.js')

var request = require('/QOpenSys/QIBM/ProdData/Node/lib/
node_modules/npm/node_modules/request');
var fs = require('fs');
var outfile = '/tmp/proxyTest.txt';
var url = 'https://ewp.co.nz/admin/login';
var proxy = 'http://10.9.31.37:3128';
const args = process.argv;
console.log(args);
request( {'url': url, 'proxy': proxy }, function(error, response,
body) { fs.writeFile(outfile, body); } ).end();

From QSH the outfile is created OK

Here is the RPGLE to invoke QP2SHELL2
*inLR = *on;
pgmnam = '/QOpenSys/QIBM/ProdData/Node/bin/node';
cmd1 = '/home/pjctest/node/proxyTest2.js' + x'00';

C Call 'QP2SHELL2'
C Parm pgmnam 37
C Parm cmd1 33

return;

From RPGLE the outfile is not created and it dies with CPFB9C6.

I'm wondering if the script needs some closing code to end it.

Regards, Peter
