What is Open Virtual Memory System (OpenVMS)?

Definition and meaning of Open Virtual Memory System

Open Virtual Memory SySTEM (OpenVMS) is a 32-Bit operating machine advanced by using Digital Equipment Corporation (DEC) in 1979 as a Laptop Server OS that runs on their VAX family of Computers, which succeeded the PDP-eleven line.

It has a complete graphical consumer Interface with photos aid and made heavy use of the concept of Digital reminiscence so that it will sell multi-consumer, time sharing, and Batch Processing capabilities.

What Does Open Virtual Memory System Mean?

OpenVMS turned into firstly just called Virtual Memory System (VMS), but it cHanged into modified to OpenVMS whilst it was retooled to work for the Alpha Processor own family. The “Open” does not denote Open Source however rather it indicates the new brought aid for Unix-like interfaces from the Portable Operating System Interface (POSIX) fashionable which incorporates preferred C features that may be ported to any POSIX-supPorting machine.

OpenVMS supports multi-user, Time-Sharing, batch, real-time and Transaction Processing through the usage of digital memory and gives excessive Availability through Clustering by using dispensing the machine over many physical machines. Clustering permits the machine to be incredibly catastrophe tolerant as it could still Characteristic even when person facts processing facilities eMerge as unavailable.

OpenVMS additionally pioneered many Functions which are now general on excessive-end server operating structures like:

• Integrated Networking
• Integrated Database capabilities as document control offerings (RMS)
• Layered Databases like Relational Databases
• Distributed report machine
• SymMetrical, asymmetrical, and non-uniForm reminiscence get admission to (NUMA) multiprocessing
• Clustering
• Shell Command Language
• High degree of security
• Hardware Partitioning for Multiprocessors
• Multiple Programming Language guide with standardized Interoperability mechanism calls among the ones languages

What does OpenVMS stand for?

When we refer to OpenVMS as an acronym of Open Virtual Memory System, we mean that OpenVMS is formed by taking the initial letters of each significant word in Open Virtual Memory System. This process condenses the original phrase into a shorter, more manageable form while retaining its essential meaning. According to this definition, OpenVMS stands for Open Virtual Memory System.
