UNAS by TRW

UNAS by TRW

[Chris Sparks]

Does know how to get the complete UNAS package from TRW?  I use it at work and I see it has an open usage clause in the source headers.  Since I am not allowed to download it from my work, maybe I can find a source elsewhere to get it?

Also are there any tutorials out there on how to use it?  I am in the process of upgrading the Ada (83 to 05) in my current project and I am getting stuck on the plethora of call being made by UNAS for which I don't even know how to set it up so it can run happily.

Doubtful.

"Out there", definitely not.  In a few closed places that still use
UNAS, perhaps but doubtful.  In the one place that I know still uses
UNAS, no.

Do I divine correctly that "your current project" is not "at work"?  If
so I would suggest you consider polyorb as a replacement(*).  UNAS is
long dead, unmaintained and unmaintainable, mostly because it is
proprietary software witout anyone getting a license for it other than
in their current application.  Also, apart from a couple of people I
know, nobody understands UNAS anymore.  The company that made it has
abandoned it, perhaps even gone bankrupt, so UNAS is mostly technical
debt.  Sorry for the bad "news".

(*) Modern multi-core computers with lots of memory might even make it
feasible to avoid distributing the software over multiple computers in
the first place.  Maybe a monolithic application would do the job just
fine, nowadays.

Actually, the customers cautiously pre-prepare marketplace corporate values.

I suspected as much.  If I could only find something that would show me how to install it and operational so I can finish my upgrade project.  Going to a new software is something that would bring on risk, unless I could narrow down what exactly the UNAS is being used for.  This effort I am working on is for the contract I am working on.

What would really help is documentation.  Installation, operation so that I can tell that it is working.

If your customer has UNAS, they probably have documentation, or what
passes as documentation.

BTW, UNAS is a framework for distributed applications i.e. multiple
programs doing remote procedure calls and message passing over the
network.

Unfortunately they don't have any documentation as it was setup very long ago.

If I had it on my home PC I would have more time to look at it.
