Maintenance tasks – Run statistics gathering (DBMS_STATS in Oracle, RUNSTATS in DB2), index rebuilds/reorgs (REORG in DB2), integrity checks, and assist with patching (PSU/RU for Oracle, fix packs for DB2).
Documentation & change execution – Maintain SOPs, log root causes for recurring issues, update knowledge base, and implement pre-approved schema/config changes during change windows with rollback plans ready.
