Oracle Database is a powerful tool for managing and storing data developed by Oracle Corporation. It is widely used in enterprise environments worldwide. Installing it on the Windows platform may seem daunting, but with this comprehensive guide, you can set it up easily. Let's start by discussing the prerequisites needed to ensure a smooth installation process.
Prerequisites
Before starting the installation, make sure that your system meets the following requirements:
- Operating System: Windows 10, Windows Server 2016 or later.
- RAM: At least 2GB (4GB recommended).
- Disk space: At least 10GB for database installation.
- Processor: Intel x86-64 or compatible.
- Networking configuration to ensure seamless connectivity.
In addition, you will need an Oracle account to download the Oracle database installation files. You can create an account on the Oracle website.
Step 1: Download the Oracle Database
First, visit the Oracle database download page through your web browser. Choose the appropriate version for your system. The current database version can be Oracle 19c or the latest available Long-Term Support (LTS) version.
You'll likely find the following download options:
- Oracle Database Software (Oracle Database 19c): Contains all the components required to install and run Oracle Database.
- Oracle Database Instances: Optional installation includes sample schema and sample applications.
Once you’ve made your selection, download the files and make sure they’re saved in a directory where you can access them easily.
Step 2: Prepare Your System
After downloading, you need to prepare your Windows environment for Oracle database installation. Follow these instructions:
Create Directories
Create a directory where the Oracle database will reside. For example:
C:\oracle\product\19.0.0\dbhome
Extract the installation files
Extract the downloaded zip files to the directory you created. You can use any decompression tool like WinRAR or 7-Zip to do this.
Step 3: Install Oracle Database
Now, you can proceed with the installation:
Run setup
Go to the extracted folder, find 'setup.exe', right-click on it and select 'Run as administrator'. Running as administrator ensures that you have the proper permissions during the installation process.
Installer Wizard
The Oracle Database Installer Wizard starts and will guide you through the process. You must:
Choose configuration
Select from the following installation options:
- Create and configure a single instance database: Select this if you need a new database.
- Install database software only: Choose this option if you plan to create a database later.
- Upgrade existing database: Select if to upgrade.
System Class
Select your system type - Desktop Class or Server Class. Desktop Class is typically better suited for personal or small-scale installations, while Server Class is for larger setups, better suited for production environments.
Select Oracle Home User
Select an existing Windows user or create a new user. It is generally a good practice to create a dedicated user for Oracle database processes.
Specify the installation location
Point to the directory that you created earlier (for example, C:\oracle\product\19.0.0\dbhome).
General installation configuration
Provide the database name and administrative password. Choose some secure name for the password and remember it for later use.
Prerequisite Checks
Before proceeding, the installer will perform the necessary checks to make sure your system is ready. If any problems appear, fix them.
To install
When the check is complete and no issues are found, proceed by clicking Install. The process may take some time, so be patient.
Completing the configuration
After installation, some configuration tasks need to be completed, such as running some scripts prompted by the installer.
Step 4: Verify the installation
To verify the installation:
Log in to SQL*Plus
SQL*Plus is a command-line tool used for database management. Open CMD and navigate to the oracle installation bin directory (for example, C:\oracle\product\19.0.0\dbhome\bin\). Enter the following command:
sqlplus /nolog
When SQL*Plus starts, login using the following:
connect to sys as sysdba;
You will be asked to enter the password set during the installation process. If the connection is successful, it means your database is running.
Step 5: Connect with Oracle Database
After confirming the installation, you can start using the Oracle database. Here are some basic commands that you may find helpful as a beginner:
Create User
Create a new user by running:
CREATE USER identified by test password;
Grant permission
Grant the new user the necessary permissions to connect and interact with the database:
provide connect,resources for testing;
Create tables
You can now create tables and insert data. Here is how to create a sample table:
create table test_table (
id number primary key,
name VARCHAR2(50)
);
Enter data
You can insert data using SQL:
INSERT INTO test_table(id, name) VALUES(1, 'Sample name');
Troubleshooting common problems
If you encounter any problems during installation, consider the following:
- Internet connection: Make sure your Internet connection is stable, as interruptions may corrupt downloads or affect configuration.
- Access permissions: Make sure you have administrator permissions.
- Antivirus/Firewall Interference: If any firewall or antivirus is interfering with the installation then disable it temporarily.

By following these steps, you will be able to successfully install Oracle Database on your Windows machine. Always remember to use secure credentials and keep your database updated to ensure it remains secure and efficient.
