Objectives

In this three-day, instructor-led, entry-level course, delegates learn about the basic concepts and facilities of IBM CICS Transaction Server V5.

After completing this course, delegates will have the prerequisite knowledge for all of the follow-on CICS application and systems programming courses that IBM Training offers.

Course objectives include:

  • 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.
