Step 2: Execute the installation program
- Double-click the downloaded exe installation program, select "Run as Administrator" in the pop-up dialog box, and run the installation program.
- Select "Install database software only" because you only need to install Oracle 11gR2 locally, so select this option.
- Click "Next".
- On the next page, you will be prompted to select the directory where you will install the Oracle database software. By default, Oracle installs the files in the C:\app\admin\product\11.2.0\dbhome_1 directory. You can choose your own location and click "Next".
- On the next page, you will need to set basic Oracle information: including the global database name, the password of the administrator user, and select Oracle to run the service automatically or manually. The automatic service will start automatically after the installation is completed, and the manual service needs to be started manually.
- Click "Next" and on the next page you need to select the components to install and configure.
- Click "Next" to complete the installation and configuration of all steps, and then the installer will start running and display the progress.
Step 3: Configure
Select to automatically configure the database during the installation process, and then click "Finish", Oracle will start the configuration. You can change the default configuration according to actual conditions. Before configuration is complete, the installer will prompt you to set network configuration, language settings, security settings, etc.
Step 4: Verify the installation
- Confirm whether the Oracle service has been started. You can confirm whether the Oracle service is started by opening the Windows Service Manager and searching for the Oracle service.
- Enter the command sqlplus / as sysdba to run SQL Plus as a system administrator. If 'Connected to an idle instance' appears, the oracle database has been started.
Summary:
