Glenn,
All you say may be true, but all it takes is for the person making the
decisions to be sold a bill of goods by the vendors.
Then, it doesn't matter what the realities are. You're preaching to the
choir; but mainframe environments continue to grow scarcer.

OK, my 2 cents..........
In the past 15 years I have heard about the mainframe 'going away' yet
it is still here and stronger then ever. At SHARE last week there
were
many stories about z/Linux taking hold and how to SOA Enable the
mainframe. As for the people issue, IBM is attempting to bridge the
gap
with the academic initiative, and as with anything new, it is going to
take time. The zNextgen project at SHARE is doing their part with
introduction sessions for those who can attend.
If you look at the enhancements of CICS and the use of specialty
processors the TOC of the mainframe is much CHEAPER then the
alternatives. Especially when you figure in all the other costs of
space, energy, cooling and people to support.............
I always get a kick out of statements like, 'our server is just like a
mainframe'. If you want a mainframe then use the mainframe. IMHO
what
really needs to be done is that the vendors have to get their heads
out
of their AIX and start writing for it again!!
MicroFocus Server Express??? All I can say is that you must not have
a
large system they are 'replacing' because I really don't see how they
can do that.
So, with that said, I am not concerned about the final 15 years of my
career, there will always be CICS and there will always be the
mainframe!!!
Getting off the soap box now.............

ahhh, the best laid plans ......
I recently received an email from an old customer of mine that had a
5year plan back in 2002, they just re-targeted" for 2012 ,,
Good luck with your conversion at ND...

I saw all the posting on ''long live the mainframe''. I
thought
I would
comment on this. As you may have seen in prior postings, ND is
slowly
but surely doing away with the m/f. We have hired a contractor
to
migrate all app's to a Linux Suse platform. We plan to be off
within
the next two years. We have scheduled this migration in four
phases.
Phase 1 will be completed by end of April. Phase 2 following
in
3-4
months. Phase 3 and 4 are more difficult and so will take more
months
for each phase then the first two.
Software to be used:
Microfocus Server Express products - this product(s) will make
the
linux processes look somewhat like the m/f. You have a jes
spool,
input/output q's, console log, and many other goodies somewhat
like the
m/f. The product has the JES feature along with a CICS
feature.
Its
somewhat amazing just how similar this product makes the
environment
look like a m/f. The product has a web based frontend.
Security is not near as good, but they are working on
improvements. They
have a Racf like component were told, but is not quite ready
yet. From
what I can see, Security will be a sore spot on the linux
side.
Software Ag products: Because we have natural/adabas shop,
those
products on the linux box run basically the same as they do on
the m/f.
Oracle/Db2 products: There are client products that have to be
installed on Linux to talk to data bases residing on their
respective
servers. So far these two areas have a gray look to them, but
they are
workable. The oracle install is somewhat or maybe I should say
very
difficult (to be truthful).
There are several other products involved, but I don't know
enough about
them to make any kind of opinion.
Conclusion:
I have worked on the m/f for the last 33 years. But now for
the
last
year or so am working on the m/f and linux platform.
One thing that I have noticed is that you have more control on
the m/f
then you do on a linux box. The scripts on the linux box
execute
with a
limited amount of intervention by the installer. This may
sound
good,
but from the products that we have for migration, it does not
work very
well.
Our management is determined to get us off the m/f. Whether it
will be
cheaper to operate the shop, time will tell. But as most of
you
know,
managers are becoming younger and for the most part have
little
or no
knowledge of the m/f. And so all they know is what runs on a
windows/linux box.
