Dileep Reddy Polakamma

I am an Oracle Database Administrator with over four years of hands-on experience managing Oracle databases (11g–19c), performing installations, upgrades, and patching across Linux and UNIX platforms. I have implemented and maintained ASM, Data Guard (physical standby), RMAN backups, and cloning procedures to support production, test, and development environments.

My work includes space management, tablespace reorganization, rebuilding fragmented indexes, gathering optimizer statistics, and query-level performance tuning using AWR and plan management. I routinely perform exports/imports (Exp/Imp, EXPDP/IMPDP), monitor alert logs and trace files, and automate backup and restoration processes.

I follow ITIL/change-management processes and have experience with RAC, PDB/CDB administration in 19c, CRON job maintenance, and working in enterprise environments for clients in healthcare, banking, and retail. I focus on reliable operations, rapid recovery, and continuous performance improvements.
