A little, and I can look through the IBM shell script to figure out some
more, but man... still more work than ADDLIBLE.. lol

So, there is no "setting" anywhere that I can just change things to point
to the new version without using the shell scripts to override the old
version?

In other words, the old version is "hard coded" to be used unless you tell
it otherwise through a script?

Is there a place I can put a shell script to do this automatically every
time I start a terminal session?

First run this command:

% which node | xargs ls -al
lrwxrwxrwx 1 qsys 0 74 Jun 3 16:04 /usr/bin/node ->
/QOpenSys/QIBM/ProdData/Node/bin/node

The "which" command gives us the path to the node binary, then I pipe that
result to the "ls" command so I can see where the symbolic link points to.
This is the key, that the symbolic link exists in the default PATH. You
could change the symbolic link by running a command like this:

ln -sf /QOpenSys/QIBM/ProdData/OPS/Node4/bin/node /usr/bin/node

The 'f' option is to force because one already exists.


With that said, IBM included a shell script named nodever.sh that does some
of this for you. You can check it out here:
http://bit.ly/developerWorks-node-v4

Does that clear it up a little?

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?

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

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')
