A mainframe computer, informally called a mainframe or big iron, [1] is a computer used primarily by large organizations for critical applications like bulk data processing for tasks such as censuses, industry and consumer statistics, enterprise resource planning, and large-scale transaction processing.
When attempting to build an application that needs to interface with an application on a mainframe computer, but no mainframe is available during development, a test harness may be built to use as a substitute this can mean that normally complex operations can be handled with a small amount of resources by providing pre-defined data and responses so the calculations performed by the mainframe ...
IBM Z Development and Test Environment can be used for education, demonstration, and development and test of applications that include mainframe components. The Z390 and zCOBOL is a portable macro assembler and COBOL compiler, linker, and emulator toolkit providing a way to develop, test, and deploy mainframe compatible assembler and COBOL ...
For example, a condition can be expressed as x IS GREATER THAN y or more concisely as x GREATER y or x > y. More complex conditions can be abbreviated by removing repeated conditions and variables. For example, a > b AND a > c OR a = d can be shortened to a > b AND c OR = d. To support this syntax, COBOL has over 300 keywords.
OpenText™ UFT One, an AI-powered functional testing tool, accelerates test automation across desktop, web, mobile, mainframe, composite, and packaged enterprise-grade applications. It was formerly known as Micro Focus Unified Functional Testing and QuickTest Professional ( QTP ).
IBM CICS (Customer Information Control System) 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. CICS family products are designed as middleware and support rapid, high-volume online transaction processing.
Teleprocessing Network Simulator (TPNS) is an IBM licensed program, first released in 1976 as a test automation tool to simulate the end-user activity of network terminal(s) to a mainframe computer system, for functional testing, regression testing, system testing, capacity management, benchmarking and stress testing.
A mainframe computer is not easy to define. Most people associate a mainframe with a large computer, but mainframes are getting smaller all the time. The terms mainframe and enterprise server are converging. Supercomputers are generally used for their speed and complexity, while mainframes are used for storing large volumes of sensitive data ...
