Re: Hosting a Large Number of Node Apps on the IBM i

Glad to have you enter the conversation, Niels!

Have you checked out the clustering built into Node.js?
https://nodejs.org/api/cluster.html#cluster_how_it_works

I have not delved into it (yet). I don't know if this feature is available
in the IBM i version because Node.js just jumped from v0.12.x to v4.x.x
(still doesn't make sense to me :-| ).

Greetings,

Sorry for just jumping into the discussion rather late. However we have
the same issues here where we alternatively are using node.js as the
frontend for IceBreak ILE application server.

Node.js has ( as you all know) one disadvantage: the one ( single)
process listening/binding to the port.

I know you can do some trix with a "fork" so it shares the same socket or
you can set up a "reverse proxy" front-end. IMHO it its to many moving
parts…

What is was looking for, was a feature in the core of the IBMI that let me
share the the socket between jobs – not only forked process. But more the
data-queue style where each process/job can listen the the next incoming
"connect". This will eventually mean that i can submit any number of
node.js jobs listening on the same port.

It seams that windows has a similar (but not exactly) feature
WSADuplicateSocket i am looking for

BTW: This will also enable me to "upscale" java jobs where "fork" is not
an option


Thanx in advance…
