CICS/TS Architecture Part 1 – Foundations Training
This course enables Systems Programmers and Systems Administrators to gain a clear and true grasp of CICS architecture from the ground up. By understanding the Kernel, the Dispatcher, the Transaction Manager and the Application Domains, not only do all of the subsequent components 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 ‘Architecture Series’ and it is recommended that they be taken in order. Parts 1 & 2 may be run consecutively or with a consolidation gap between them.<br><br>This course is available for one-company, on-site presentations and for live presentation over the Internet, via the Virtual Classroom Environment service.
- describe the domain architecture of CICS/TS
- explain the dispatching of work on multiple TCBs including L8, J8, SO, SL and QR
- describe how work gets into CICS by a variety of means
- explain how the Loader and Program Manager domains work
- debug CICS system and transaction problems
- discuss IPCS and the CICS verbexit
- tune CICS/TS
- describe the CICS-DB2 interface
- describe the exploitation of Threadsafe programs.
Experience of the externals of CICS, such as application and/or systems programming and/or resource definition and administration is preferred. Prior CICS internals knowledge is not required.
