yet another VMS client gone (extended...)

Following the thread from WIM.....

Why clients are migrating UNIX/LINUX even when VMS is having several advantages...?

Comments please !!!!

Because that's where the new (sexy) products are. And on Windows. And here : even back to manual processing.

Well, if HP are not telling anyone that VMS has several advantages...

And if one of the few people at HP who IS telling everyone is made redundant...

Go figure!
Have fun,

If it can't be done with a VT220, who needs it?

Re: yet another VMS client gone (extended...)

To my experience, many people, in particular today's managers, ignore the total cost of ownership of a system, and simply choose what other people do because they don't know any better and are afraid to swim against the stream, even when it is the right thing to do. Windows pretending experts exist like sand on the beach. Unfortunately that often results in Windows, or some Unix box if a vendor strongly recommends it.

I think the bottom of the problem for server systems like OpenVMS is the huge influence from the home user market. The home market has choosen Windows with all it's lights and whistles, and the people are so sick of it that they don't even want to try or learn anything else anymore. And history... that was yesterday!

You have to count that since Palmer took control of DEC, they have been trying to kill off VMS. It's only the loyal users that keep it running and the fact that nothing has the
same reliability.

However, so much of our military is thankfully
done in VMS according the mill specs that VMS
support must stay around or this nation is
in big trouble.

There are some new sites where people are smart enough to recognize the obvious advantages of VMS Clustering. Heck, with a
cluster you can split it to two sites, and if one site blows up, the other site takes over with no loss of data. You might have to play with quorom to make the second site
work, but with shadowing it's absolutely amazing. And clusters were around in the 80s with built in file locking at the record level.

And VMS Shadowing is still from an operational point incredibly useful. Unlike
hardware mirroring, you can have disks on different controllers in different buildings.
Or take a disk off line and due an upgrade, and if something goes wrong, just go back to the original disk. A disk starts showing errors, add a disk to the shadow set, and then take the trouble maker out of the picture, with zero down time, transparently to users.

These are just a few features that have been around for ages and beyond the rest of the industry. Well, Oracle Rack uses VMS distributed lock management code.

It's amazing that Intel for years tried to move to an Intel based, alternative solution, but their FABs had to be running every day. Maybe on Christmas day they may let a cluster reboot for a good reason.

And you'll find people with clusters that have been up for years, all while doing upgrades, adding new machines, storage, even new architecture, with availability being a constant.

I keep on saying the word "Market". The best thing would be if HP sold VMS to a company that wanted to market it. It would take off again like a bat out of hell.
