CICS: Customer Information Control System - An IBM licensed program that provides online transaction processing services and management for critical business applications. CICS runs on many IBM and non-IBM platforms (from the desktop to the mainframe) and is used in various types of networks that range in size from a few terminals to many thousands of terminals. The CICS application programming interface (API) enables programmers to port applications among the hardware and software platforms on which CICS is available. Each product in the CICS family can interface with the other products in the CICS family, thus enabling interproduct communication.
DFSMS: "DFSMS" represents "Data Facility Storage Management Subsystem." An IBM licensed program that provides storage, data, and device management functions
DNS: Domain Name Server - In the Internet suite of protocols, a server that responds to queries from clients for name-to-(IP)address and address-to-name mappings as well as for other information.
EREP: Environmental Record Editing and Printing Program. A program that makes the data contained in the system recorder file available for further analysis.
FTP: File Transfer Protocol - In the Internet suite of protocols, an application layer protocol that uses TCP and Telnet services to transfer bulk-data files between machines or hosts.
IPL: Initial Program Load 1. The initialization procedure that causes an operating system to commence operation. 2. The process by which a configuration image is loaded into storage at the beginning of a work day or after a system malfunction. 3. The process of loading system programs and preparing a system to run jobs.
ISPF: Interactive System Productivity Facility - An IBM licensed program that serves as a full-screen editor and dialogue manager. Used for writing application programs, it provides a means of generating standard screen panels and interactive dialogues between the application programmer and terminal user.
Java: An object-oriented programming language for portable interpretive code that supports interaction among remote objects. Java was developed and specified by Sun Microsystems, Incorporated.
JCL: Job Control Language - A control language used to identify a job to an operating system and to describe the job's requirements.
JES: Job Entry Subsystem - An IBM licensed program that receives jobs into the system and processes all output data produced by the jobs.
Linux: An open source implementation of the UNIX system.
LPAR: Logical Partition - A subset of a single system that contains resources (processors, memory, and input/output devices). A logical partition operates as an independent system. If hardware requirements are met, multiple logical partitions can exist within a system.
MVS: Multiple Virtual Storage. Implies MVS/390, MVS/XA, MVS/ESA, and the MVS element of the z/OS and OS/390 operating systems.
OS/390: Pertaining to the IBM operating system that includes and integrates functions previously provided by many IBM software products (including the MVS operating system) and (a) is an open, secure operating system for the IBM S/390 family of enterprise servers, (b) complies with industry standards, (c) is Year 2000 ready and enabled for network computing and e-business, and (d) supports technology advances in networking server capability, parallel processing, and object-oriented programming.
POSIX: Portable Operating System Interface - a set of standard operating system interfaces based on UNIX. Unix was chosen for its universality, then it was standardized for portability across hardware systems.
TSO: Time Sharing Option - An option of the MVS operating system that provides interactive time sharing from remote terminals.
USS: Unix Systems Services - IBM's implementation of Unix OS that runs under z/OS.
z/OS: Pertaining to the IBM operating system that includes and integrates functions previously provided by many IBM software products (including the MVS operating system) and (a) is an open, secure operating system for the IBM Z series of enterprise servers; (b) complies with industry standards; (c) enabled for network computing and e-business; (d) supports technology advances in networking server capability, parallel processing, and object-oriented programming; can run Linux (in a separate LPAR) and/or USS.
