VSE (operating system)

z/VSE (Virtual Storage Extended) is an operating system for IBM mainframe computers, the latest one in the DOS/360 lineage, which originated in 1965. It is less common than prominent z/OS and is mostly used on smaller machines. Primary z/VSE development occurs in IBM's Böblingen labs in Germany.

Overview

DOS/360 originally supported 24-bit addressing. As the underlying hardware evolved, VSE/ESA acquired support for 31-bit addressing. IBM released z/VSE Version 4 in 2007. z/VSE Version 4 requires 64-bit z/Architecture hardware and supports 64-bit real mode addressing. With z/VSE 5.1 (available since 2011) z/VSE introduced 64 bit virtual addressing and memory objects (chunks of virtual storage), that are allocated above 2 GB. The latest shipping release is z/VSE 5.2.0 - available since April 2014.

IBM recommends that z/VSE customers run Linux on z Systems alongside, on the same physical system, to provide another 64-bit application environment that can access and extend z/VSE applications and data via Hipersockets using a wide variety of middleware. CICS, one of the most popular enterprise transaction processing systems, is extremely popular among z/VSE users and now supports recent innovations such as Web services. DB2 is also available and popular.

Dos (Fanny Lu album)

Dos (English: Two) is the title of the second album by Colombian Pop and Vallenato singer, Fanny Lu. The album was released in Colombia on December 8, 2008, and in the United States and Puerto Rico the following week. In Colombia, Dos went straight to number one in the album charts in its debut week. The album features the lead single and the official song of the year in Colombia, "Tú No Eres Para Mi" (You Are Not For Me).

Album information

The album was greeted with huge anticipation following the success of the lead single "Tú No Eres Para Mi". The hit was number one on Colombian radio for eleven weeks. As well as this, there were high expectations considering the success of Fanny's first album, Lágrimas Cálidas (English: "Warm Tears"), which spent nine weeks at number one in Colombia. Fanny Lu produced the album and co-wrote many of the tracks, most notably "Un Minuto Más" (English: "One More Minute"), a duet with Noel Schajris. The song is a tribute to her late father who was murdered. Weeks before the release of the album, Fanny stated that "We were looking for a fusion of sounds. I didn't limit myself. I gave myself the luxury of exploring, because it was important not to repeat what I'd done. For example, many times, instead of accordions, we experimented with winds. This album is like a walk along all those genres I love, and all the songs have their own palate and color."
