AUDIENCE:
Online system analysts, designers and programmers.
OBJECTIVE:
Improve the individual's ability to design efficient, reliable and user
friendly CICS application systems.
DESCRIPTION:
This course is an extensive overview of system design considerations
and common design errors. The key issues in this class are high performance,
reliability, user satisfaction, and flexibility of CICS application systems.
Many application functions can be satisfied by more than one CICS facility.
This class will cover the pros and cons of each facility. Students will
better understand when to use or when not to use a particular facility.
Performance and reliability will be stressed throughout the class.
Many other useful topics such as 24 hour systems, human engineering, system
sharing, and others are also included.
WORKSHOP:
None.
PREREQUISITES:
The CICS Introduction and Concepts class is strongly recommended.
