Audience Profile

This basic course is designed for IT personnel who have little or no CICS experience.

At Course Completion

Upon completing this course, students will be able to:

  • Describe the role of CICS in a business transaction environment
  • Outline the flow of a typical CICS transaction
  • Describe the functions that the primary CICS-supplied transactions perform
  • Use the CICS master terminal transaction (CEMT) to query and control system resources
  • Describe various ways of defining resources in CICS
  • Use transactions that CICS supplies to define and manage resources
  • Explain how CICS stores and manages resource definitions
  • Describe the features of the CICS Explorer
  • List the facilities that CICSPlex System Manager provides
  • Describe how CICS implements security
  • List the recoverable resources of CICS
  • Describe CICS transaction backout and forward recovery
  • List the types of CICS startup and shutdown
  • Describe the facilities that CICS provides for maintaining the integrity of data that is associated with CICS programs
  • Describe CICS support for databases and Virtual Storage Access Method (VSAM) files
  • Describe the functions of presentation, business, and data access logic
  • Define the role and use of the COMMAREAs and CHANNELs in CICS applications
  • Show how CICS Basic Mapping Support (BMS) supports the 3270 display
