Overview
This course continues the 'Architecture Series' by introducing additional CICS/TS domains such as Storage Manager, Log Manager and Recovery Manager. Also included are components such as Temporary Storage, Transient Data and Interval Control which probably are readily familiar from an 'externals' perspective, however here we complete the entire picture of how they work, how they are managed and how they can be debugged. Additionally we introduce Web Services, Sockets, Web and EJB functionality.
This course is available for one-company, on-site presentations and for live presentation over the Internet, via the Virtual Classroom Environment service.
Prerequisites
Prior attendance on the course CICS/TS Architecture Part 1 - Foundations is recommended.
Delegates will learn how to
- describe 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 Services and the Pipeline Manager Domain; Web and Document Handler domains and obtain a brief introduction to CICS EJB functionality.
