Hi,
I am the VM system programmer. I don't see VM systems are popular as z/OS. And I don't even see VM topics in this website. Is this system dying? How many of you use VM systems? I just wonder.

VM applications are migrated to other technologies.

Hi,

from my previous experience in Mainframe system programming.
the challenging task is that to make on interface between VM's to other operating system's

and the resources they need.Just as a system programmer you know hardly how many peoples they are skilled in system programming.

Not only VM machines now all the companies they start slowey migarting process for legacy systems to non legacy systems due to lot of reasons mainly cost and unavilabily of skilled resource.

they cant do it,in a single night bez already the old mainframes consist of tera bytes of data's.Now all companies start migrating data's slowly,

as i conclud not only VM Machines whole Mainframes are slowly Dying.

Its my thought,corrections always welcome.


Cheers,
kumaresh.M

Hello,

I believe this is inaccurate.

Moving data cross-platform is rather easy and straightforward.

One slowdown in moving data off the mainframe is the investment in millions or even billions of lines of mainframe source code (COBOL is not the only language that has large systems running on the mainframe).

Another is that for large, integrated systems, typical win-based server-farm systems cannot carry the load. Several of the large installations i've supported have backed off of the migration from mainframe to oracle or sqlserver because of infrastructure and performance reasons.

Skilled resources are in short supply in all 3 environments (MF, UNIX, Win-based) from what i see - especially win-based. There are many, many win-based certified people around, but many of them are totally unqualified - which does a dis-service to the ones who are really good. Just my $.02.

Strange, I've never given a second thought to VM....I learned on a VM system end of the 80's, and haven't used one since....only MVS and the various flavours (ESA, z/os, yaddayaddayadda).

I'm sure mainframes will eventually be replaced, but until the industry comes up with an architecture that can support thousands of users concurrently during business hours, and then crunch the numbers overnight that Cobol/assembler/etc can.....
