Launching the Installation Wizard
Once the download is complete, locate the downloaded executable file and double-click it to launch the Oracle Database 18c XE installation wizard. The wizard will guide you through the installation process, providing options and prompts along the way.
Choosing Installation Options
The installation wizard presents several options that allow you to tailor the installation to your needs. These include:

- Database Configuration: You can specify the database name, administrator password, and other configuration settings.
- Installation Location: You can select the directory where you want to install Oracle Database 18c XE.
Setting Up the Database
The installation wizard will prompt you to create a database user account. This account will have administrative privileges and control access to the database. Choose a strong password and remember it, as you’ll need it to connect to the database later.
Completing the Installation
After configuring the installation options, the wizard will begin installing Oracle Database 18c XE on your system. This process may take some time, depending on your system’s hardware and network speed. Once the installation is complete, you’ll be presented with a success message.
Verifying the Installation
To ensure that Oracle Database 18c XE has been installed successfully, you can verify the installation by connecting to the database using SQL*Plus. Open a command prompt and navigate to the Oracle Database 18c XE installation directory. Enter the following command:
“`

“`
This will launch SQL*Plus. Now, log in to the database using the administrator account you created during installation:
“`
CONNECT / AS SYSDBA
“`
If you are able to connect to the database successfully, the installation has been completed successfully.
Connecting to the Database
To connect to the database from other applications, you’ll need to use a database client. Oracle provides several client tools, including SQL Developer, which is a powerful IDE for database development. You can download and install SQL Developer from the Oracle website.
