Oracle Database – administration, configuration and maintenance of databases

Training process

Training needs analysis

If you have specific requirements regarding the training programme, we will carry out a training needs analysis for you. This will guide us on which aspects of the programme should receive greater emphasis, so that the training programme meets your specific needs.

What will you gain?

Confident Oracle Administration - You will learn how to manage Oracle instances, databases, and schemas on your own, so you can handle day-to-day DBA tasks more efficiently and bring structure to database operations.

Reliable Environment Setup - You will practice Oracle installation plus instance, memory, and file configuration, making it easier to build a stable environment that is ready for daily use and future growth.

Stronger Data Security - You will learn how to manage users, roles, profiles, and privileges, and how to apply security policies and TDE so you can protect data better and reduce the risk of misuse.

Effective Backup and Recovery - You will master RMAN backup planning, full and incremental backups, and recovery procedures, so you can restore systems faster after failures, mistakes, or data loss incidents.

Faster Issue Diagnosis - You will work with AWR, ASH, logs, and alerts to identify the real causes of performance drops, understand database behavior, and respond more quickly to production problems.

Better Query Performance - You will analyze execution plans, indexes, and system parameters, helping you tune SQL more effectively, remove bottlenecks, and improve application response times in practice.

DBA Task Automation - You will use DBMS Scheduler and PL/SQL scripts to automate routine administration, backups, and maintenance work, saving time while reducing the number of manual mistakes.

Higher System Availability - You will understand the basics of Data Guard, RAC, and failover procedures, which will help you design more resilient environments and prepare systems for outages more effectively.

What are the prerequisites for participating in the training?

Basic SQL Skills - You should be comfortable reading and writing simple SQL queries and understand tables, relationships, and basic data operations so you can keep up with the hands-on exercises.

Database Fundamentals - You should understand core database concepts such as instances, schemas, users, indexes, and backups so you can follow Oracle administration topics more effectively.

Operating System Basics - You should be able to navigate an operating system, work with files and directories, and run basic commands, since part of the course covers environment configuration.

Technical Experience - You should have basic experience working with IT systems or database applications so you can quickly understand the context of maintenance, security, and admin tasks.
