Howard, Opps I forgot to wish Wayne all the best and enjoys his life beyond mainframes. It is sad to see all the folks leaving the list who helped me when I was a VM systems programmer starting out all those years ago. I am not sure how many Mainframes there are left in the North West of England. As far as I know all the Local Government sites that used to have mainframes until only a couple of years ago have retired them. I know a couple of banks still employ mainframe staff in Greater Manchester but as far as I know none still use VM. However I think there are only a few un-employed Mainframe staff. Most, like me, have re-trained and moved away to Solaris, Linux and Windows. Dave G4UGM

Of course it's disheartening to see another VM shop bite the dust but that's the way things seem to be going these days. Perhaps this is a sign of the times. Of course there will, for the most part, be mainframes around for those organizations which require lots of horse power but that doesn't translate into an increase in mainframe shops running z/VM and/or z/OS. As we all know, IBM mainframe sales were down last year. And most of all, this situation doesn't translate into new mainframe jobs of any flavor, whether they be for older highly experience Systems Programmers or some newbie fresh out of college who has taken some classes in a program IBM has formulated. All what we have here is a situation were there is a pool of both experienced systems programmers and would be systems programmers who are unemployed. --- On Tue, 1/5/10, Richard Troth <[email protected]> wrote: From: Richard Troth <[email protected]> Subject: Re: Moving on: The University of Maine (System) shuts down mainframe To: [email protected] Date: Tuesday, January 5, 2010, 2:34 PM Dave -- This is ridiculous. Do you really want to start a religious war on the value of Windows ... on this discussion list? To your two points, cost and flexibility, I dig in for further analysis as follows. COST Windows is not more cost effective. It carries a finer grained price point profile than MVS or VM or even most Unix. But it is hardly "cost effective" (for servers) in any shop bigger than a local funeral parlor. Given the availability of Linux (and before that, low end Unix) even its smaller per-unit charge is at risk. I will abstain from repeating the scalability numbers we all know and love because I am lazy. You get the point. Windows is inexpensive at the start but quite the opposite later. FLEXIBILITY Windows is actually LESS flexible (for servers) when you consider that it cannot run (traditionally) without a mouse as well as keyboard. The very idea is counter to anything like "lights out". But that's just one point. What is flexibility? Linux, traditional Unix, VM, and even MVS have so many more knobs to turn than Windows does. And Windows presents more penalty when you start "turning knobs" than do these other systems. I state this without specific evidence because having heard the horror stories more than once, I have filed the info away: one does not adjust Windows. If you disagree, and the moderator will indulge us, then I will start finding and posting documented evidence. Now to my two points: sexiness and vanity. SEXINESS Windows is familiar. That at a minimum is comfort. It is emotional. Salesmen LOVE when you get emotional. Do you yourself not know Windows enough to drive its menus and figure out some amount of configuration? But menu-driven config does not scale past one or two servers, and then we're back to cost. So perhaps I have stretched and implied that anything salsemen love is sexy. But I did not mean that. Windows really is (my opinion) nice looking. Windows is graphical ... in its very name. (And as I suggested in a prior paragraph, one cannot usually turn off the graphics, which gets us back into flexibility. But I digress.) Graphics are sexy. 3D is even sexier, but who can argue that visual offers more immediate gratification than verbal? Pictures are appealing. VANITY One definition of "vanity" is a self focus. Windows is an excellent candidate for per-user service. I prefer Linux in that role only to avoid corporate entanglement and "closed source" bondage, NOT because there is something wrong with the op sys. Windows supports an individual user quite nicely. But for servers ... not so well. I submit to you that many customers have decided on Windows because they only brought in their own experience, and that with the presentation end. Might as well use the vanity mirror in your bath room for the furnace at Odeilo. Another English definition of "vanity" is triviality or hollowness. (Am trying to avoid the blunt "lack of value" because I already said Windows DOES have some value.) Using Windows for server service in your data center is vanity. Unless driven by vendor requirements for software that you chose for other reasons than flexibility or scalability, Windows is simply NOT the right choice for that infrastructure. -- R; <>< On Tue, Jan 5, 2010 at 07:57, Dave Wade <[email protected]> wrote: >> -----Original Message----- >> From: The IBM z/VM Operating System >> [mailto:[email protected]] On Behalf Of Richard Troth >> Sent: 05 January 2010 01:04 >> To: [email protected] >> Subject: Re: Moving on: The University of Maine (System) >> shuts down mainframe >> >> >> Actually, Jack nailed it.
