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

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
example:

---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?

Before you start your app you can run:

node -v

From within your app you could try this:

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

using the new or old Node version with my application? (not just the

adapter).

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

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

use

the new version?
