CICS Interview Questions And Answers

Mainframes :: Customer Information Control System Job Interview Questions and Answers

CICS Interview Questions and Answers will guide us now that CICS (Customer Information Control System) is a transaction server that runs primarily on IBM mainframe systems under z/OS and z/VSE. CICS is a transaction manager designed for rapid, high-volume online processing. This processing is mostly interactive (screen-oriented), but background transactions are possible.
