There are a multitude of problems with XMLSERVICE. It's over-engineered
and contains many hacks for various things thrown in willy-nilly. This
creates a combinatorial problem of supporting it and adding new features,
especially without breaking existing users. The project basically started
as a hobby project by Tony to show what could be done from RPG; I don't
think he ever intended for it to become what it has become: the bedrock on
which customers are running their businesses from PHP, Python, Node, .NET,
etc...

It has served fairly well, all things considered, but in order to have
something sustainable and maintainable going forward we need to take the
lessons learned from this project and build something leaner, cleaner, and
all around better. This seems to be heading towards ILEusion, which is a
project designed around RPG microservices. Personally, I'd have rather it
be written in C, since I think it is the best language suited for this
type of project (at least that's available on IBM i, especially within
ILE), but AFAIK nobody from the community (including vendors who use
XMLSERVICE within their products/toolkits) stepped up to help out with
XMLSERVICE/DB2SOCK. Meanwhile, Liam is chugging along.

There seems to be some new open source projects starting up with intent
to replace XMLSERVICE, so nothing official or near imminent I don't
think.

Personally I would say improve on XMLSERVICE rather than do a full
re-write, but I didn't create XMLSERVICE. I just use it so I don't know
the complexity.

For now I would say for open source stuff the XMLSERVICE component seems
to be the correct go-to unless there's already a native DB2 interface
like I think PHP has and of course Java has as well with JT400.

In the case of a general PASE ibmdb2 layer, I'm just thinking about a
consistent layer that can be used by all open source languages, not just
.Net. DB2 connect seems to be the right answer for this, but it's not
"officially supported" to run on IBMi. I installed the AIX version with
a few hacks and it works somewhat (still working out kinks) with the
unixODBC stuff for .Net.

However the "not officially supported" always lingers �

Until more time can be spent on DB2 Connect, XMLSERVICE seems pretty
stable and it's fast from my usage so far with and without .Net on i.

Hi Richard,

I had not heard that IBM was thinking about deprecating and replacing
XMLSERVICE. I'll keep an eye out for any news about that.

Just out of curiosity, would the "AIX style ibmdb2 layer" you have in
mind be something that other languages running on PASE could use (e.g.,
JS with Node or Python)? Or would it be specific to .NET via the Mono
port?

Thanks,
