Advanced CICS
| Duration: 3 days |
| Participants: This course is designed for students who are experienced COBOL CICS developers who need to program more efficiently and use some of the newer CICS features of CICS TS and CICS/ESA. |
|
Objectives:
Upon successful completion of this course you will be able to:
- Describe and use new features in CICS TS and CICS/ESA. - Use a variety of efficient techniques to reduce the size, run-time, and transmission time of CICS programs. - Describe the impact of multiple and remote regions and use them to write more complex systems. |
|
Overview:
- This course focuses on writing efficient, complex CICS Applications and using new features found in CICS TS and CICS/ESA. |
| Prerequisites: A working knowledge of CICS COBOL programming is required. |
| Format: Lecture and hands-on computer workshops. |
