z/OS is a 64-bit server operating system from IBM. It is the new name for the existing IBM mainframe system OS/390, combining MVS and UNIX System Services (a mainframe implementation of Unix formerly known as MVS Open Edition).While retaining many features, functions, and interfaces harking back to the 1970s and even 1960s, z/OS also offers many of the same attributes and elements of so-called open systems. So while CICS, IMS, RACF, SNA, and the like are still
available and in daily use, they are less the focal point for new applications than in years past. z/OS now also runs Java, supports UNIX ( Single UNIX Specification) APIs and applications, and easily communiates with TCP/IP and Web protocols. A complementary IBM product, z/VM, allows running LinuxThis article is about Linux-based operating systems, GNU/Linux, and related topics. See Linux kernel for the kernel itself. See Linux (washing powder) for the Swiss brand of washing powder. Tux, a plump penguin, is the official Linux mascot Linux is the n applications on the same system. This combination of z/OS updates and Linux-on-zSeries enablement has done much to modernize the mainframe.
1 Notes
In the same December 2001 rebrand:
- S/390 became zSeriesSince December, 2001, IBM designates all its mainframes with the name eserver zSeries with the e depicted in IBM's well-known red trademarked symbol. Nonetheless, the term zSeries now popularly refers only to IBM's newest line of 64-bit mainframes, starti, the "z" standing for "zero down-time";
- AS/400The AS/400 is an IBM minicomputer for small business and departmental users, released in 1988 and still in production under the name iSeries . The AS/400 is an object oriented system with an integrated database that was designed to implement E. Codd's rel became iSeries and in April 2003 i5IBM system, successor of the AS/400 and iSeries system. Based on a Power 5 chip., but OS/400OS/400 is an operating system used on IBM's line of AS/400 minicomputers. OS/400, along with the AS/400 line of minicomputers, was introduced in 1988. OS/400 has subsystems built into it that allow IBM System/3x applications to run on the AS/400 hardware remained OS/400, rather than becoming "i/OS";
- RS/6000The IBM pSeries formerly called RS/6000 (for R ISC S ystem 6000 , is IBM's current RISC/ UNIX-based workstation computer line. Announced in 1990, the RS/6000 replaced the RT-PC. It is based on the IBM POWER CPU architecture and runs the AIX operating syst became pSeries and in July 2004 p5, the "p" standing for "performance", but AIX remained AIX, rather than becoming "p/OS";
- NetFinity became xSeries
