CICS Transaction Server - Concepts & Facilities

This two-day course introduces and explains CICS Transaction Server (CICS/TS) to those who have limited or no knowledge of CICS but who need a clear understanding of what CICS is, what it does and how it does it. The course describes and explains the main concepts and facilities of CICS, and introduces the growing family of CICS server and client products that are available. This course is the essential first step for anyone wishing to work effectively in a CICS environment, and forms a solid foundation on which future CICS education can be based.

The next step

For those training in software development, the next CICS course to take is the five-day CICS/TS Application Programming Workshop.
If your interest is in CICS administration or systems programming, then the next course you should consider is CICS Transaction Server Systems Administration.
