Virtual Memory System


Virtual Memory System

(operating system)(VMS) DEC's proprietary operating system originally produced for its VAX minicomputer.

VMS V1 was released in August 1978. VMS was renamed "OpenVMS"around version 5.5. The first version of VMS on DEC Alphawas known as OpenVMS for AXP V1.0, and the correct way torefer to the operating system now is OpenVMS for VAX orOpenVMS for Alpha. The renaming also signified the fact thatthe X/Open consortium had certified OpenVMS as having a highsupport for POSIX standards.

VMS is one of the most secure operating systems on the market(making it popular in financial institutions). It currently(October 1997) has the best clustering capability (bothnumber and distance) and is very scalable with binariesportable from small desktop workstations up to hugemainframes.

Many Unix fans generously concede that VMS would probably bethe hacker's favourite commercial OS if Unix didn't exist;though true, this makes VMS fans furious.
