This comprehensive guide takes you from absolute beginner to proficient Oracle Database Administrator through a carefully structured series of lessons and hands-on exercises. You’ll start with an introduction to the Oracle environment, learning how to prepare your practice setup on Linux and Windows so you can follow along with real-world examples.

The course then explains the fundamentals of relational database management systems (RDBMS) and provides a detailed overview of Oracle Database technologies, roles and responsibilities of a DBA. You’ll explore Oracle Database architecture, tablespaces, datafiles and the core components that keep an enterprise database running.

Practical modules walk you through installing and creating Oracle databases step by step, both on Linux and Windows. You’ll work with essential Oracle tools such as SQL-Plus and SQL Developer, learning how to start up and shut down database instances, configure initialization parameters, manage SPFILE and PFILE, and query the data dictionary to monitor and optimise your system.

You’ll also master Oracle’s multitenant architecture by creating container databases (CDB) and pluggable databases (PDB), performing basic multitenant administration tasks and understanding how this feature improves scalability and resource management. Finally, the course covers managing database memory, concepts and practices for tuning memory allocation, and performing essential DBA tasks that mirror what professionals do in production environments. By the end of the course, you’ll be able to confidently administer Oracle databases and apply best practices in real-world scenarios.
