What are the key skills and qualifications needed to thrive as an AS/400 Computer Operator, and why are they important?

To thrive as an AS/400 Computer Operator, you need a solid understanding of IBM iSeries (AS/400) systems, job scheduling, and system monitoring, often supported by relevant IT certifications or experience. Familiarity with tools such as IBM Navigator for i, job control languages (JCL), and backup/recovery utilities is typically required.
