What you’ll learn

Discover the essential elements of Oracle Database and the core administration tasks every small-scale Oracle DBA should acquire. From setting up Oracle 12cR2 to managing users, storage and backups, this practical course gives you the capacity to make your day-to-day projects more manageable and efficient.

Installing Oracle Database

A reliable installation is the foundation of effective administration. In this course, you’ll learn how to plan for a successful Oracle Database 12cR2 setup by assessing system requirements, preparing the operating environment, and using the Oracle Universal Installer (OUI) step-by-step. You’ll explore Oracle’s flexible architecture, set environment variables, and understand the purpose of the Oracle Inventory. We’ll also cover safe removal procedures to ensure you can cleanly de-install software when needed.

Using administration tools

Different administration tasks call for different tools. You’ll work hands-on with SQL Developer, Enterprise Manager Express, and SQL*Plus to perform a variety of configuration, monitoring, and troubleshooting tasks. We’ll compare the strengths of each tool and show you practical workflows so you can choose the right approach for the task at hand, whether you’re checking performance metrics, modifying user accounts, or updating database settings.

Oracle networking

Without proper networking configuration, your database can’t be accessed effectively. This course introduces Oracle Net concepts and takes you through configuring and managing the Oracle Net Listener. You’ll practise setting up local naming with Net Manager, test connections with TNSPING, and manage listener services from Enterprise Manager. By the end of the course, you’ll be able to create a stable, secure connection environment for your databases.

FAQs

Over two immersive days, you’ll gain increased confidence in Oracle 12cR2 administration. In our live labs, you’ll explore tools like SQL Developer and Enterprise Manager Express, perfect if you’re managing a smaller database and want to build your expertise.

Is this course right for someone new to database administration?

Yes – if you understand relational database basics and can write basic Oracle SQL statements, you’ll be able to follow the content. The course is designed for those starting to handle administrative tasks for small-scale Oracle databases, such as support engineers, sysadmins, or junior DBAs.

Will I learn to create and configure a database from scratch?

Definitely. You’ll gain hands-on experience with the Database Configuration Assistant (DBCA), exploring storage options, CDB versus non-CDB configurations, workload-based database types, and character set selection so you can design and deploy environments tailored to specific needs.

Does the training include performance monitoring techniques?

Yes. You’ll learn to use Oracle’s built-in monitoring architecture, including Automatic Workload Repository (AWR) and Automatic Database Diagnostic Monitor (ADDM), alongside additional advisor tools. This ensures you can track performance trends, identify bottlenecks, and apply informed improvements.

How much will I need to know about Linux or UNIX?

Only a basic familiarity is recommended. The course is delivered on a Linux platform, and all relevant commands will be demonstrated in context, so you’ll pick up practical operating system skills as you progress through the exercises.

Will the skills apply to newer Oracle versions?

Yes. Although the focus is on Oracle Database 12cR2, the administration techniques also apply to 18c and 19c, as the core tools and processes remain consistent.
