Position Overview

We are seeking a seasoned Oracle Database Administrator (L3) with 5–7 years of hands-on experience specializing in Oracle Database environments running natively on Windows Server platforms (2016 through 2025).

The ideal candidate will have deep expertise in managing Oracle Standard Edition 2 (SE2) environments (12c/19c), navigating Windows OS-specific architecture (threads, services, and memory allocation), and maintaining high availability without relying on Enterprise-only features. You will play a pivotal role in maintaining daily operational stability, executing infrastructure migrations, and creating structured SOPs to delegate routine monitoring tasks to NOC teams.

Windows & System Administration
• Install, configure, patch, and manage standalone Oracle 19c databases natively on Windows Server platforms.
• Perform OS-level database administration on Windows,



including Windows Service management (net stop/start), Windows Registry configuration, and thread-level session troubleshooting using native utilities (orakill).
• Manage memory allocation (SGA and PGA) within the single-process oracle.exe Windows memory boundary to prevent pagefile swapping and ORA-04030 errors.

Core Database Operations & SE2 Optimization
• Administer databases within Standard Edition 2 (SE2) architecture, leveraging CDB/PDB multitenant models while working within SE2 hardware and CPU limits.
• Perform routine database maintenance: user management, tablespace/datafile growth forecasting, schema management, and security auditing.
• Execute Release Update (RU) patching and database upgrades on Windows environments with minimal operational downtime.
• Execute database migrations, refreshes, and Data Pump (EXPDP/IMPDP) exports/imports across Windows hosts.
