Re: Ending a node web server from QSH session -- WEB400

It's an option when running interactively, but what about when you want to fire up your server in a batch process? QSH is fine really (as long as you set the environment variable that allows multi threading - can't remember which one it is though)

Crap. Scratch what I said about bash. I just remembered I've had race
condition issues with it when exiting the Node.js REPL. Instead use
zsh(n1) from perzl (if you go this route).

Here are the install instructions for zsh (reference the article first to
learn how to install the base shell scripts):

$ cd /QOpenSys/download
$ ./wwwperzl.sh aix61 wget zsh-5.0.5
$ ./wwwperzl.sh aix61 rpm zsh-5.0.5

I don't have an answer for QSH but can offer a significantly better
alternative...

In this article** I describe how to install Git from perzl.org. The same
can be done to install bash (bourne again shell). Then you should run
STRTCPSVR *SSHD to start ssh on your IBM i. Then from your laptop run "ssh
ibmiprofile@ibmi_ip_address" to log into your IBM i. And once logged in
run "bash" and that will put you in a bash shell.

Or a shorter option would be to skip bash and only do STRTCPSVR *SSHD and
use the default Korn shell that comes with IBM i. In this option you'd
still use something like putty to create an ssh connection to your IBM i.
Then once in putty you can use Ctrl+C to end a node server.

My managers have given me the green light to explore node on the IBM i
(7.1).

I'm following the IBM developerWorks getting started page at:
https://www.ibm.com/developerworks/ibmi/library/i-native-js-app-ibmi-with-nodejs/.
The section of the page called "Create a web application using Node.js" has
instructions for developing a hello world web server. I was able to get the
hello world web server to run successfully:
* I created the sample.js file
* I put the sample.js file in the IFS
* I started a qshell session
* I executed the command "node /mydirectory/sample.js".
* I confirmed the web server was running by pointing my browser to the
URL and seeing the hello world message.

Here's where I got a little confused. The developerWorks page says:

"To end the web server job, you can press the Esc key within the QSH
session and select option 2 to work with the current jobs. Next, end the
job running the node program with option 4 as shown in Figure 6."

While still in the qshell session, I pressed the escape key on my
keyboard, but I did not get any options at all. I did not see a way to
follow these instructions for ending the job. I used F3 to exit the qshell
session. I pointed my browser to the URL, and it returned the standard
browser message saying the page was not available.

If a node web server is started in a qshell session, is it okay to end
the web server by simply stopping the qshell session?

Why did I not see any options when I pressed the escape key while in the
qshell session?

Thanks,
