This course is perfect for CICS Systems and Applications Programmers who are responsible for solving CICS Systems and Transaction dumps.
Delegates should have two-to-three years experience coding CICS Command Level Applications, and should have some knowledge of programming.
Knowledge of COBOL is desirable but not essential.
3 days. Hands on.
Upon completion of this course, attendees will:
- Be able to confidently debug transactions dumps
- Be more self-sufficient when dealing with application problems
- Understand the methodologies of dump solving
