CICS V6.1 for Systems Programmers (TD-CICSSP)

Audience

This course is intended for:

  • IBM CICS Systems Programmers
  • Technical CICS Programmers needing a better understanding of CICS


Prerequisites

Ideally attendees should have one or two years experience supporting CICS Transaction Server.


Duration

5 days. Hands on.


Course Objectives

This CICS for System Programmers course covers the latest version of CICS 6.1. Upon completion, attendees will be able to understand how to install CICS/TS using zOSMF and customize a new CICS system using DFHISTAR. They will be able to describe how CICS resources are defined and how CICS Communicates with VTAM and TCPIP. The attendee will understand the RACF Security interface, the VSAM and DB2 interfaces as well as the Operational and Intersystem Communication Interfaces. The major CICS Utilities are also covered as is Startup and Shutdown, Recovery and Logging. The attendees will also be able to describe the CICS-MQ Interface, Threadsafe and understand CICS Web Services. A CICS 6.1 system will be available for online access and workshops. This course is also available at previous releases, please ask for details.
