z / VSE ( V irtual S torage E xtended ) is an operating system for IBM - mainframe computer . The development takes place mainly in Böblingen in Germany at IBM Deutschland Research & Development GmbH. It's not as widespread as z / OS and is mostly used on smaller systems. z / VSE is the successor to VSE / ESA , VSE / SP, DOS / VSE , DOS / VS and DOS / 360 . The roots of z / VSE lie in the 1960s and the System / 360 .
description
The latest release 6.2 of the IBM Z operating system has been available since December 1st, 2017.
With z / VSE V5.1, 64-bit virtual addressing was supported for the first time . On April 7th, z / VSE version 5.2 was announced. This version was available on April 25, 2014.
z / VSE originally only supported 24-bit addressing. As the underlying hardware evolved, z / VSE also introduced support for 31-bit addressing. In March 2007, IBM released z / VSE version 4. z / VSE Version 4 supports the z / Architecture and thus 64 bit real addressing.
IBM continues to recommend that customers run a Linux-on-System z on the same system as the z / VSE . This 64-bit Linux system can extend z / VSE applications and access z / VSE applications and data through HiperSockets . In addition, a wide variety of middleware products can be used on Linux-on-System z .
The interface for batch processes is JCL ( Job Control Language ). There is also an interface for z / VSE console operators. CICS is one of the most widely used transaction monitors and is very popular with z / VSE customers. Today, CICS also supports the latest innovations such as B. Web Services. With z / VSE V6.1 a new CICS version was introduced. DB2 is also available for z / VSE.
Like z / OS, z / VSE supports traditional 3270 terminals as a user interface. Most customers have now started to access their applications using a web browser . For historical reasons, the TCP / IP implementation is a product that has to be paid for separately and is offered in two different versions by two software manufacturers. Most customers today use TCP / IP.
The z / VSE operating system celebrated its 50th birthday in October 2015. With z / VSE 4.1, IBM introduced 64-bit real addressing. The version z / VSE 3.1, which was discontinued in mid-2009, was the last version compatible with 31-bit mainframes; subsequent versions from version 4.1 onwards require a 64-bit capable mainframe server.
