Customer Information Control System (CICS) is a family of mixed language application servers that provide online transaction management and connectivity for applications on IBM Mainframe systems under z/OS and z/VSE.
A computer cluster is a set of loosely or tightly connected computers that work together so that, in many respects, they can be viewed as a single system.
In IBM mainframe computers, a Coupling Facility or CF is a piece of computer hardware which allows multiple processors to access the same data.
Extended Remote Copy or XRC is an IBM zSeries and System z9 mainframe computer technology for data replication.
Global Resource Serialization (GRS) is the component within the IBM z/OS operating system responsible for enabling fair access to serially reusable computing resources, such as datasets and tape drives or virtual resources, such as lists, queues, and control blocks.
High availability is a characteristic of a system, which aims to ensure an agreed level of operational performance, usually uptime, for a higher than normal period.
The International Business Machines Corporation (IBM) is an American multinational technology company headquartered in Armonk, New York, United States, with operations in over 170 countries.
IBM Db2 contains database-server products developed by IBM.
Global Mirror is an IBM technology that provides data replication over extended distances between two sites for business continuity and disaster recovery.
IBM Information Management System (IMS) is a joint hierarchical database and information management system with extensive transaction processing capabilities.
IBM mainframes are large computer systems produced by IBM since 1952.
IBM System z9 is a line of IBM mainframe computers.
In IBM mainframes, a Cross-system Coupling Facility, or XCF, is a component of z/OS that manages communications between applications in a sysplex.
IBM Z is a family name used by IBM for all of its mainframe computers from the Z900 on.
A logical partition, commonly called an LPAR, is a subset of a computer's hardware resources, virtualized as a separate computer.
Mainframe computers (colloquially referred to as "big iron") are computers used primarily by large organizations for critical applications; bulk data processing, such as census, industry and consumer statistics, enterprise resource planning; and transaction processing.
Middleware is computer software that provides services to software applications beyond those available from the operating system.
Multiple Virtual Storage, more commonly called MVS, was the most commonly used operating system on the System/370 and System/390 IBM mainframe computers.
An operating system (OS) is system software that manages computer hardware and software resources and provides common services for computer programs.
Parallel computing is a type of computation in which many calculations or the execution of processes are carried out concurrently.
Peer to Peer Remote Copy or PPRC is a protocol to replicate a storage volume to another control unit in a remote site.
Peer-to-peer (P2P) computing or networking is a distributed application architecture that partitions tasks or workloads between peers.
RACF, short for Resource Access Control Facility, is an IBM software product.
Resource Measurement Facility (RMF) is a performance monitor for the z/OS Operating System.
In distributed computing, a single system image (SSI) cluster is a cluster of machines that appears to be one single system.
A supercomputer is a computer with a high level of performance compared to a general-purpose computer.
Virtual Storage Access Method (VSAM) is an IBM DASD file storage access method, first used in the OS/VS1, OS/VS2 Release 1 (SVS) and Release 2 (MVS) operating systems, later used throughout the Multiple Virtual Storage (MVS) architecture and now in z/OS.
z/OS is a 64-bit operating system for IBM mainframes, produced by IBM.
