Multiple Virtual Storage


Multiple Virtual Storage

(operating system)(MVS) Release 2 of OS/VS2, called MVSbecause it had multiple 16 MB virtual address spaces, incontrast to SVS. MVS ran on the IBM 390 seriesmainframes. It became MVS/SP, then MVS/XA (with 31-bitaddressing) and then MVS/ESA.

MVS/Open Edition (MVS/OE), aimed at the growing open systemsmarket, added TCP/IP and Unix support in an MVS addressspace, allowing users to run IBM, CICS-type applications,batch applications and Unix.

MVS/ESA was repackaged as OS/390 as a marketing exercise butit's basically the same thing.
