Hi Scott,
While I've heard of zPDT, I don't really know/understand what is does or
offers a vendor. Sounds like zPDT is an affordable and effective platform.
Too bad some vendor did not use it to develop an z/OS EMR package for
hospitals that already have a z/OS infrastructure.
It offers vendors who have no need for a sysplex a cheap
development/testing/demo environment that they can run on a laptop,
desktop or rack server.
It would be interesting to see how it measures up running a production
workload on the latest x86 iron like
http://www-03.ibm.com/systems/x/hardware/enterprise/x3850x5/specs.html
compared to a business class mainframe like a z114.

Hi John,
System z is not cheap (does it start around $1M?). I expect the
traditional
mainframe operating systems, like z/OS, z/VM, etc., to have a
significant
price tag. I'm not sure what the pricing is for the zLinux variety
of
operating system. Free does not get you business class support. Add
to that
the environment, DASD, etc., it's hard for the startup vendor to put
all
that in his garage :-)
It seems like they are trying to prevent the creation of smaller more
affordable "mainframes". What happened to P/390, FLEX-ES? Is there
any way
to legally run z/OS on Hercules? If a small vendor needs coupling
facilities, I think he is out of luck.

I am not sure, but the PC in impinging on the z in many ways. IMO,
one
reason is that some very creative people can afford their own PC and
tools (especially if they use Linux). The investment is very low
compared to a z. And the "vendor" can then market the product to
many
more people. Most every office in the world has PC class servers.
Take
the EMR package. If it is priced correctly and easy to use, then the
market into local doctor's offices is immense compared to, say, only
into a major hospital (which could possibly afford a z). I know my
personal doctor has some sort of PC based software. I see them (and
my
dentist) using it. And the doctor no longer writes physical
prescriptions. He just enters it into his laptop; it then ends up
going to my pharmacy; and they send a text to my phone when it is
ready to pick up. I really don't see much of any reason for
"application level" code on the z any more. Things like DB2, maybe.
But CICS? Sorry, it is simply easier to create a "web" based
transaction using WAS or JBOSS or Tomcat on a server. Doing so is
more
cost efficient for our size (and shrinking) business. The only
reason
we continue with CICS/COBOL is that we do incremental changes. We
don't have the money to convert from CICS or batch COBOL to
something
else (likely Microsoft .NET based <shudder/>).

In my company's case, it's not a matter of asking our vendor to

with
IBM. The vendor already works with IBM, but has chosen to phase
out
their
mainframe product and create a new one that runs on PC-based
servers.
For
various reasons, the hospital decided to open the field and look
for
a new
Electronic Medical Record (EMR) package across all platforms. My
understanding is that there is no viable EMR package available on
the
z/OS
platform. This made me wonder -- is there no EMR vendor who chose
to
develop their product on the z/OS platform? I expect that
successful
vendors carefully chose their platform(s). If they are not chosing
z/OS,
why not?
