    Virtual Machine/Enterprise Systems Architecture™ (VM/ESA™) represents the next major milestone in the history of the VM family of operating systems. It is a single product that supports both centralized and distributed computing systems in a way that preserves data integrity and protects shared resources. Operating systems of this kind are essential to the use of computers today, as ... View full abstract»

    The rapid evolution of distributed and personal systems in recent years has not diminished the importance of centralized computing. Today, systems at all levels need to operate in networked configuration to allow users and applications to access and manipulate data from anywhere with full integrity and optimal performance. Virtual Machine/Enterprise Systems Architecture™ (VM/ESA™) sa... View full abstract»

    Release 1.1 of the Virtual Machine/Enterprise Systems Architecture™ (VM/ESA™) operating system introduces a new function called VM Data Spaces, provided through a new virtual-machine architecture called Enterprise Systems Architecture/Extended Configuration (ESA/XC). ESA/XC is the strategic VM/ESA virtual-machine environment for Conversational Monitor System (CMS) users and service v... View full abstract»

    The interpretive-execution facility of Enterprise Systems Architecture/390™ (ESA/390™) provides an instruction for the execution of virtual machines. This instruction, called START INTERPRETIVE EXECUTION (SIE), was initially created for virtualizing either System/370 or 370-XA architectures, and was used later for virtualizing ESA/370™ and ESA/390 architectures. SIE has evolve... View full abstract»

    Discussed is work toward satisfying requirements on the Conversational Monitor System (CMS) in the areas of data sharing and physical DASD space sharing. This work advances the present CMS file system design that allows only active read sharing among users on a single VM system, where each user has a reserved, private allocation of DASD space for file data. Described in this paper is the CMS Share... View full abstract»

    A system service for coordinated recovery of resources is a critical function needed for distributed processing environments because applications need to provide for data integrity while the location of the data and processes are transparent to the application. VM is the first IBM operating system to provide Coordinated Resource Recovery as a system service rather than as a service provided by uni... View full abstract»

    Coordinated Resource Recovery is a Virtual Machine/Enterprise Systems Architecture™ (VM/ESA™) function for providing consistency of changes to multiple resources in environments that include distributed applications. It provides a uniform solution for applications to the problem of resource consistency. Systems management of Coordinated Resource Recovery in VM/ESA (CRR) is the set of... View full abstract»

    This paper discusses the concepts and facilities of the Shared File System (SFS) support for Virtual Machine/Enterprise Systems Architecture™ (VM/ESA™) Coordinated Resource Recovery (CRR). It includes background information on limitations that lead to SFS support for coordination of file recovery functions. The level of support provided by the Virtual Machine/System Product (VM/SP) R... View full abstract»
