Definition
(Context: Hardware)
IBM® CICS® Transaction Server is a family of scalable general-purpose transaction processing solutions for z/OS, VSE/ESA, and distributed platforms. These servers support large transaction volumes with fast, consistent response times and provide high availability and scalability at a low cost per transaction.
CICS manages the sharing of resources, the integrity of data and prioritization of execution, with fast response. CICS authorizes users, allocates resources (real storage and cycles), and passes on database requests by the application to the appropriate database manager (such as DB2). We could say that CICS acts like and performs many of the same functions as the z/OS operating system.
