Re: [IBMiOSS] How to tell the system which version of Node to use -- OPENSOURCE

Kevin,

Thanks, that's much better.

Now, I don't see a .profile file under /home/<userid>. I assume I can
create one.

I also don't see /QOpenSys/etc/profile either. Is that just a file without
an extension one could create? Or should it be /QOpenSys/etc/.profile that
we would create?

PATH is kind of like your library list. By default, PASE uses
/QOpenSys/usr/bin:/usr/ccs/bin:/QOpenSys/usr/bin/X11:/usr/sbin:.:/usr/bin
as you noted.

Due to how the OPS stuff is shipped, we can't switch over Node 0.12 to
Node v4. Instead, we ship them under different subdirectories in ProdData.
I *believe* that the node developers also created a /QOpenSys/usr/bin/
node4 symlink you can use instead of node if you want to ensure that you
use Node v4.

If you want to set your PATH to be persistent. Just add a line to your
~/.profile:

export PATH=/QOpenSys/QIBM/ProdData/OPS/Node4/bin:$PATH

and every time you start a PASE shell, your PATH will be set.

If you want to do it "system wide" you need to add the line to
/QOpenSys/etc/profile instead.

Aaron, (or anyone else)

Can you (or anyone else) tell me then how my system is already set to

use

the old version vs. the new version? It must be something in the

current

path.

Somewhere the system has to be being told "use this version". I want

to

tell it to use the new version. This should be something simple to do I
would hope without making a shell script.

I see in /usr/bin the node command (v0.12.13) as well as many others

(ls,

curl, jar, etc) Can I replace any files in there to make it use the new
version instead of writing a script?

Sorry to be a pest, but this will be asked MANY times in the future, I'm
sure of it. :)

When I use

echo $PATH
I get:

/QOpenSys/usr/bin:/usr/ccs/bin:/QOpenSys/usr/bin/X11:/usr/sbin:.:/usr/bin

When I use

export PATH=/QOpenSys/QIBM/ProdData/OPS/Node4/bin:$PATH

And then node -v, it does claim to be using the new version. But... I

want

to set it to use it system wide, not just for my particular session.

Am I asking the wrong question? :) I apologize if I am... but I would
hope this would be something simple, something documented by IBM (or the
OSS group).

IBM released Node4, I would hope there were some documentation on how to
set your system to use it besides needed to create a shell script. When
they release the next version, the path would be the same to use the new
version, or to be able to go back to the old version.

I use shell scripts to set the environment before starting my app. For

---start.sh---
export PATH=/QOpenSys/QIBM/ProdData/OPS/Node4/bin:$PATH
PORT=80 node app.js

And then put it in a SBMJOB..

SBMJOB JOB(QSH CMD('/path/to/start.sh'))

Yep, it shows v0.12.13. I know node4 is installed. I also know how

to

check the version.

So, again I ask, how do I tell my applications (or my system if

that's

the

right terminology) to use the new version?

Any other changes to source needed besides that? How do I know

just the

That depends what you mean by "convert". Node4 uses ES6 which

has

a

number

of new features. With that said, the primary thing you need

to be

aware

of

is the changed path of the DB2 adapter. Going off of

memory...

Node v0.12.x
var db =

require('/QOpenSys/QIBM/ProdData/Node/os400/db2i/lib/db2')

Node v4.x
var db =

require('/QOpenSys/QIBM/ProdData/OPS/Node4/os400/db2i/lib/db2')

Just looking through my system I see I have Node4 installed.

Is there a "simple" way to convert my apps done with the old

version

to

use

the new version?
