Installing the Oracle Database Software

This topic explains how to run Oracle Universal Installer to perform most database installations.

Note:

• If you plan to use Oracle Restart or Oracle ASM, then you must install Oracle Grid Infrastructure for a standalone server before you install and create the database. Otherwise, you must manually register the database with Oracle Restart.

• You may have to shut down existing Oracle processes before you start the database installation.

• You can install Oracle Database by using the silent or response file installation method, without the GUI. This method is useful to perform multiple installations of Oracle Database.

To install the Oracle Database software:

1. Log in to Windows as an Administrator user.

   If you are installing on a Primary Domain Controller (PDC) or a Backup Domain Controller (BDC), log on as a member of the Domain Administrators group.

2. If you are installing Oracle Database on a computer with multiple Network Interface Cards or multiple aliases, use System in the Control Panel to create the ORACLE_HOSTNAME system environment variable. Set this variable to point to the host name of the computer on which you are installing Oracle Database.
3. Navigate to the location for Oracle Database 18c, open a command prompt with administrator privileges, and run the setup.exe command.
4. Follow these guidelines to complete the installation:

   • Do not install Oracle Database 18c software into an existing Oracle home.

   • Follow the instructions displayed in the Oracle Universal Installer. If you need additional information, click Help.

   • Do not modify the Java Runtime Environment (JRE) except by using a patch provided by Oracle Support Services. Oracle Universal Installer automatically installs the Oracle-supplied version of the JRE. This version is required to run Oracle Universal Installer and several Oracle assistants.

   • If you encounter errors while installing the software, see for information about troubleshooting.

   • If you chose an installation type that runs Oracle Database Configuration Assistant in interactive mode, then you must provide detailed information about configuring your database and network.

     If you need help when using the Oracle Database Configuration Assistant in interactive mode, click Help on any screen.

     Note:

     If you chose a default installation, Oracle Database Configuration Assistant does not run interactively.

5. When the Configuration Assistant tasks are complete, click Finish, click Exit, then click Yes to exit from Oracle Universal Installer.
6. Optionally, delete the OraInstalldate_time directory to remove the temporary files that were created during the installation process. The OraInstalldate_time directory holds about 45 MB of files. This directory is created in the location set by the TEMP environment variable setting.

   Restarting your computer also removes the OraInstalldate_time directory.
