CICS TS Systems Administration

SEE SCHEDULE

Duration: 5.0 days

Method: Instructor-led. Hands-on workshops.

Price: $3400.00

Course Code: CI4000


Audience

This course is designed for administrators of CICS Transaction Server for z/OS.

Description

This course has been updated to incorporate the new facilities and functions introduced in CICS TS V5. This 5-day instructor-led course is intended for those who have the responsibility for administering CICS TS systems. The course combines formal lectures with a series of practical exercises. Over the course of the week, the attendees build and operate an actual CICS TS system from scratch. The Hands-on exercises provide the opportunity to create a CICS region from scratch. Once created, subsequent lectures and exercises will allow the definition and management of resources within it. The topics and exercises are delivered in a sequence providing a logical sequence to the process and an opportunity to add a CICS to a CICSPlex.

Objectives

Upon successful completion of this course, the student will be able to:

  • Perform all CICS administration duties
  • Use CEDA transaction to dynamically define resources
  • Use other administrative interfaces such as the CICS Explorer and DFHCSDUP utility.
  • List the process of adding a CICS to a CICSPlex
  • Maintain the macro coded table entries
  • Explain the effect system Initialization parameters have on performance, reliability, and availability.
  • Define and understand the use of resources and facilities such as: Terminals, Profiles, Task dispatching, System initialization, Programs, Mapsets, Virtual storage management, Inter CICS channel communication using (MRO, ISC, and IPIC), Event Processing, File definitions, LSR pool usage, Temp Storage and Transient Data queues, Db2 and WMQ connectivity, CICS Logging, Event processing and much more.

Prerequisites

A basic knowledge and experience of CICS. Students are encouraged to bring along their resource definitions.
