Description
The purpose of this class is to enable Systems Programmers to begin building an understanding of CICS architecture from the ground up. By understanding the Kernel, Dispatcher, Transaction Manager, and the Application domains, not only do all of the subsequent components in the ‘Structure & Debugging’ fall into place, but also the fundamentals for Debugging, Performance Tuning and Application Design begin to become a reality. There are two parts to 'Structure & Debugging’ and it is recommended that they be taken in order. Parts 1 & 2 may be taken consecutively or with a short consolidation gap between them.
Objectives
Upon successful completion of this course, the student will be able to:
- Understand all aspects of CICS Storage Management including solving and preventing Storage Violations
- Manage Logstreams and understand Recovery Management issues
- Manage and understand Temporary Storage and Transient Data expectations
- Understand communication with CICS either via Terminal Control or Sockets domain
- Appreciate the features delivered by Web and Document Handler domains and obtain a brief introduction to CICS EJB functionality
Prerequisites
Extensive experience of the externals of CICS such as application and/or system programming and/or resource definition and administration is required. Prior CICS Internals knowledge is not required.
