Oracle database is a very powerful database management system that is widely used in various enterprise-level applications and websites. When installing Oracle, you usually have the option of using the GUI installer or using the command line installer. This article will introduce how to install the Oracle database using the command line installer.
Step 1: Download the Oracle database installation package
First, download the appropriate Oracle database installation package from the Oracle official website. Before downloading the installation package, you need to confirm the operating system and bit number of your computer. Select the corresponding version to download according to your needs.
Step 2: Unzip the Oracle database installation package
After the Oracle database installation package is downloaded, you need to unzip the installation package. It is recommended to extract the installation package to a folder that does not contain spaces, such as: /home/oracle/instantclient_19_8.
Step 3: Prepare the installation file
Before installing the Oracle database, you need to prepare a response file. The response file is an XML format file that contains all the options that need to be installed. When installing, you can use a response file to avoid manually entering installation options. You can create a response file through the following command:
cd /home/oracle ./configure -silent -responseFile $PWD/db_install.rsp
This command will create a response file named db_install.rsp in the /home/oracle directory.
Step 4: Perform command line installation
After preparing the installation files, you can start command line installation. It can be executed through the following command:
cd /home/oracle/database ./runInstaller -silent -responseFile /home/oracle/db_install.rsp
When the command is executed, the Oracle installation program will automatically run and the Oracle database will be automatically installed in the background. It should be noted that you need to enter the password of the Oracle account during the installation process, so be sure to remember this password.
Step 5: Verify whether the Oracle database is installed successfully
After the installation is completed, you can use the following command to verify whether the Oracle database is installed successfully:
sqlplus / as sysdba
If the installation is successful, You will see output similar to the following:
SQL*Plus: Release 19.0.0.0.0 - Production on Sat Dec 26 16:24:49 2020 Version 19.3.0.0.0 Copyright (c) 1982, 2019, Oracle. All rights reserved. Connected to: Oracle Database 19c Enterprise Edition Release 19.0.0.0.0 - Production Version 19.3.0.0.0 SQL>
If it fails, relevant error information will be prompted. If you encounter a problem, you can troubleshoot it through Oracle's official documentation.
Summary
Installing an Oracle database through the command line can simplify and automate the database installation process. Although some configuration and preparation work is required during the installation process, once successfully installed, we can easily manage and monitor the Oracle database. I hope this article can help Oracle database beginners learn to install Oracle database using the command line.
