Oracle 19c | MS SQL Server | Oracle RAC | Linux / Windows | 24x7 Production

• Production Ownership: Administered 20+ Oracle 19c databases across Standalone and RAC production environments supporting FedEx mission-critical logistics workloads with 99.9%+ uptime; maintained zero SLA breaches attributable to DBA actions over 2.5 years.
• RMAN Backup & Recovery: Designed and executed RMAN backup strategies (Full + Incremental L0/L1, Crosscheck, Restore, Clone) for 15+ Oracle 19c databases; reduced RTO to under 2 hours through documented recovery runbooks and periodic restore validation in non-prod.
• SQL Performance Tuning: Diagnosed and resolved 12+ high-impact SQL performance issues in FedEx production using AWR, ASH, and execution plan analysis; applied composite indexing and query rewrites to achieve up to 40% reduction in query response time, directly improving application SLA adherence.
• Python DBA Automation: Built Python automation suite using cx_Oracle, paramiko, and smtplib to automate tablespace capacity alerts, session-kill scripts, peak-load HTML reports (delivered from jump server via email), and scheduled health-check scripts — eliminating 4–6 hours/week of repetitive manual DBA effort.
• Incident Management (RCA): Owned P1/P2 incident resolution in 24x7 FedEx environment; diagnosed ORA-04031 (shared pool exhaustion), ORA-01555 (snapshot too old), tablespace full, redo log corruption, and archive log gaps using a structured Diagnose → Isolate → Fix → Validate → Communicate → Prevent framework.
• Oracle RAC Operations: Operated Oracle RAC clusters: managed cluster services (srvctl start/stop/status), node-level operations, VIP / SCAN listeners, OCR/voting disk health checks, and inter-node diagnostics using crsctl; coordinated planned failovers during maintenance windows.
• Data Guard / DR: Familiar with Oracle Data Guard architecture (primary/standby roles, redo log shipping, switchover/failover via dgmgrl); observed and documented DR drill procedures in FedEx standby environment; actively building hands-on lab on Oracle 19c XE.
• Administration & Security: Managed tablespace capacity planning, user provisioning, role/privilege administration, and security compliance tasks across 20+ schemas; coordinated with application and infra teams during deployments and planned maintenance windows.
• MS SQL Server: Supported MS SQL Server 2019 backup/restore operations and Always On Availability Group monitoring; handled failover validation and log-shipping gap resolution.
