• Create and manage database objects (e.g. tablespaces, tables, indexes, packages) and run DB2 utilities (LOAD, UNLOAD, REORG, RUNSTATS) for physical maintenance.
• Collaborate with developers to optimise SQL queries and indexing strategies, perform performance tuning, and ensure data integrity best practices are upheld.
• Automate tasks using JCL, REXX, COBOL, and Python; deploy application releases and troubleshoot related issues.
• Monitor tablespace capacity, implement RACF-based security protocols, manage backup and disaster recovery procedures, and maintain technical documentation.
