OSNews, Generic OSes "HP has announced the end of support for OpenVMS, the ancient but trustworthy server operating system whose creator went on to build Windows NT. OpenVMS started out as VAX/VMS on Digital Equipment Corporation's VAX minicomputers, then later was ported to DEC's fast Alpha RISC chips " before the Compaq acquisition of Digital led to their untimely demise. HP ported the software to the Itanium, but HP isn't going to bother moving to the last generation of IA64 and support will finally end in 2015." The article seems to have confused the end of support of VMS (which projected to happen some time after December 2020) with the end of IA64 sales for machines that support VMS and/or the end of support of the Alpha version of the operating system, but it seems either way that the venerable operating system is on its way to meeting the same fate as MPE.

Those are not examples, per se, more like folklore/hearsay and personal bias/opinion. I was looking for specifics.

You want specifics on why OpenVMS is better? Like, "OpenVMS can context switch 12.5% faster than an equivalent Unix kernel", or "OpenVMS has a maximum of 128 processes, whereas Unix has 92"?

Well, I dont see the point of a listing things that OpenVMS does better. It is like "Windows has 32 kernel locks, and Mac OS X has only 16, therefore Windows is better" or "NTFS has 256 character filenames, and ZFS has only 192, therefore NTFS is better" (I made up all examples). Dont you agree that a list of specifics does not tell the whole story?

If you have the chance, talk with sysadmins instead. Preferable those who worked in Enterprise and on Unix servers and on OpenVMS servers. And worked with high availability clustering. Hear their war stories. I think this tells more than a list. Best is of course to work with both OS yourself for a couple of years, but that is not realistic? Second best alternative, talk with people who knows, or read text by people who knows.
