It is a general-purpose transaction processing subsystem for the z/OS® operating system. CICS provides services for running an application online, by request, at the same time as many other users are submitting requests to run the same applications, using the same files and programs.
CICS stands for " Customer Information Control System ". It is an Online Transaction Processing (OLTP) system and application server that provides online transaction management and connectivity for applications running on mainframes under z/OS.
CICS stands for Customer Information Control System. CICS was developed in 1968 by IBM. CICS allows users to develop and execute online application in an MVS environment. CICS has become the most commonly used server for Internet applications.
In our first of our intro to the mainframe series of articles, Melita Saville from IBM walks us through CICS (Originally called the Customer Information Control System), how it connects diverse applications, and more. Learn more about CICS and how it can be used on mainframe today.
CICS (Customer Information Control System) is middleware that sits between the z/OS IBM mainframe operating system and business applications. As an online transaction processing (OLTP) system, it is used to build customer transaction application programs.
For CICS to support such a great range of businesses and types of applications, it must be flexible. A key part of CICS flexibility is the way that it defines and processes the resources that it needs and how resources are defined and managed separately from the applications that use them.
It is an Online Transaction Processing (OLTP) system and application server that provides online transaction management and connectivity for applications running on mainframes under z/OS. CICS is often referred to as an online system for mainframes.
