Hi Wayne:

You're likely to get answers all over the board on this one, but perhaps
that is exactly what you want.

Other than some obvious restraints, like virtual memory, network
bandwidth,
CPU cycles, etc., I have never heard of an IDMS system that could not
support the maximum concurrent number of users (albeit I had a lot of
fun
during the Cullinet years doing performance and tuning consulting to
achieve
exactly that result ;-}} ).

That said, I suspect you may be asking about life in the 'new world',
with
web services, etc.

I have personally simulated 10K users hitting an ASP page that
connected/retrieved minimum data from an IDMS database. I don't have
all
of the details anymore, but the overall response was about 1.17 seconds
running the simulation for about 15 minutes. This was done on CA iron
in
2003/2004 on a R14.1 CV.

Of course, it was just a simulation, but it illustrates that you can
push a
rather large load through a CV if you have enough back-end resources.
Again, just my 2cents...your results WILL vary...

Does anyone have an idea of the concurrent number of users IDMS can
handle?

Re: concurrent users
"John,

I took a look at the sysgen manual and it doesn't specify the number of pte/lte combos allowed. In the Pterm syntax the repeat count has a max of 32767, so I would presume the max allowed will be 32K...assuming there is enough memory.

OK, now, how high can I go as far as adding connections go (adding lterm
pterm pairs)? Is there a limit? It is probably not a finite number, it
probably is based on what resource or storage pool that gets used up?=20

Thanks again Lutz. =20
