CICS TS V6 Internals Module 1 [TS61]

This class aims to enable Systems Programmers to begin building an understanding of CICS architecture from the ground up. By understanding the Kernel, Dispatcher, Transaction Manager and Application domains, not only do all of the subsequent components in the ‘Internal’ fall into place, but also the fundamentals for Debugging, Performance Tuning and Application Design begin to become a reality. There are two modules in the ‘Internals’ and it is recommended that they be taken in order. Modules 1 & 2 may be taken consecutively or with a short consolidation gap between them

This comprehensive ten-day 'Boot Camp' type course provides attendees with an accelerated learning approach to system support for CICS Transaction Server (CICS TS) for z/OS. The course is designed for students new to the CICS TS for z/OS environment who need to develop the skills to administer the product. The hands-on lab exercises follow presentation topics giving students the opportunity to try out their newly-gained skills immediately. 

The course will start with an introduction to CICS TS for z/OS concepts and facilities. Students will work on an existing CICS TS and subsequently build a CICS TS from scratch and use the CICS provided tool, such as CEMT, CEDA, and the CICS provided batch utilities. The use of the CICS Explorer to define and manage CICS resources will be introduced. Once created, subsequent lectures and exercises will allow the definition and management of additional resources within a CICS TS region. 

The student will advance past the basic build of a CICS region to defining and supporting more advanced resources such as “bundles” and the “event binding” area and more.

The student created CICS will be configured to connect to WMQ and as part of a CICSPlex.
