IBM Course Code: WM820
This five-day instructor-led course is designed to teach experienced CICS system programmers advanced resource definition and tailoring skills, enabling them to fully leverage the many features available in today's CICS environments.
This course teaches students advanced CICS topics, including troubleshooting, configuration and tailoring, and CICS support for Web services. IBM CICS is a modern transactional application server designed to execute demanding mixed-language application workloads, and to enable those applications to be easily integrated with enterprise solutions.
Through a combination of instructor-led lectures and hands-on labs, students learn about topics such as planning for recovery, CICS integration with IBM DB2, problem analysis, CICS interproduct communication, database services, external interfaces to CICS transactions, and CICS integration with IBM WebSphere MQ. The course also teaches students the system programming and administration aspects of service-oriented architecture (SOA) and CICS Web services.
The hands-on lab exercises are designed to reinforce the lecture material and give students the opportunity to practice newly acquired CICS system programming skills, including application debugging and working with Web services.
This course is applicable to all releases of CICS TS V3.
