Topictrick: Mainframe Skills and Modernisation
Main focus
Topictrick centres on enterprise technology skills, from IBM mainframes, COBOL and JCL to DB2, CICS, z/OS, software architecture, APIs and Claude AI. It connects foundational concepts with the practical concerns of legacy-system modernisation and technical interviews.
Why it matters
Preparing for a mainframe interview, diagnosing a DB2 problem or revising core programming concepts gives the material a clear use. The combination of specialist platform coverage and system-design topics suits learners building confidence across established enterprise environments.
Style
Long-form deep dives aim for sustained explanation, while short animated pieces support quicker revision. Recent lessons include DB2 errors, query-plan reading, recovery strategies and programming statements, creating a mix of conceptual teaching and focused troubleshooting.
Consistency
Monthly publishing supports a steady learning rhythm, with recent releases alternating concise explainers and longer practical lessons. Several IMS backup-and-recovery uploads cover closely related ground.
- IBM mainframe fundamentals
- COBOL and JCL programming
- DB2 diagnosis and query analysis
- IMS backup and recovery
- z/OS and CICS concepts
- Software architecture and APIs
- Enterprise technology interviews
Editorial note
Use current vendor documentation and workplace-specific standards when applying database recovery, operational or configuration guidance.
