This CICS Certification Course goes beyond legacy syntax to cover how organizations run CICS today, alongside Java, REST APIs, containers, and OpenTelemetry-based observability. You practice writing and debugging CICS-COBOL programs, defining resources, and monitoring transactions inside a live mainframe environment. The curriculum maps to real job requirements for CICS developers and system programmers, closing the gap between classroom theory and what banks, insurers, and airlines need on day one.
Prerequisites
This CICS Certification Course is built to accommodate both beginners and working mainframe professionals. Before you start, it helps to have:
- A basic understanding of mainframe concepts (z/OS, TSO/ISPF) – not mandatory, as a refresher is included
- Familiarity with COBOL programming, since most CICS applications are written in COBOL
- General awareness of file structures such as VSAM or relational databases like Db2
- No prior CICS experience is required – foundational modules bring newcomers up to speed
Course Objectives
- Understand CICS architecture, the transaction lifecycle, and resource management
- Build and deploy CICS-COBOL applications using both classic and modern development tools
- Configure and manage CICS regions, transactions, programs, and system tables
- Apply CICS security models, including RACF-based access control and zero-trust principles
- Debug and troubleshoot CICS applications using CEDF, CICS Explorer, and dump analysis
- Integrate CICS with Db2, VSAM, MQ, and modern web services
- Build the practical foundation needed to pursue recognized CICS and IBM Z certification paths
What You Will Learn
- CICS architecture: regions, tasks, transactions, multitasking, and multithreading
- BMS mapsets, physical/symbolic maps, and pseudo-conversational programming
- Command-level CICS programming with COBOL, including EXEC CICS and error handling
- File control, VSAM processing, and Db2 integration within CICS programs
- CICS Web Services, JSON support, and REST API enablement for legacy programs
- Java in CICS: Liberty JVM servers, Spring Boot support, and container extensions
- CICS security: RACF integration, resource-level protection, and audit readiness
- Monitoring and tuning with CICS Performance Analyzer and OpenTelemetry tracing
- Modern tooling: CICS Explorer, Zowe Explorer, and VS Code-based development workflows
- Problem determination using CEDF, CEMT, transaction dumps, and trace analysis
