How to install oracle silently on linux

When using a Linux environment, sometimes you may need to install the Oracle database on the operating system. At this time, a simple and effective method is to use silent installation mode to install Oracle. This article will introduce how to use silent installation mode to install Oracle database.

First, we need to download the installation file of the Oracle database. Before downloading the installation file, we need to confirm whether the Java Software Development Kit (JDK) has been installed on the Linux operating system we are running. You can check whether the JDK has been installed by entering "java -version" on the command line. If it is not installed, you need to install it first.

Next, download the Oracle installer appropriate for your server operating system version and architecture. The download address of the installer can be found on the Oracle official website.

After downloading the installation file, we need to unzip the file and open the installation folder. Running the "runInstaller" script will start the installation process.

Before running the script, we need to enter the "xhost" command on the command line to set the access permissions of the X server. In this way, the Oracle installer can access the X server.

Next, we need to open the runInstaller script. You can make the file executable by right-clicking the runInstaller file, selecting "Properties", and checking "Allow executing file as program" in the "Permissions" tab. To run a file through the command line, use the following command: ./runInstaller.

The Oracle installer will display a graphical user interface, and we need to follow the instructions of the installation wizard to complete the installation. There will be many parameters that need to be configured in the installation program, and using silent installation mode can automate these processes.

Silent installation mode requires you to create a response file in advance and use the configuration file to set parameters when executing the installation script without waiting for the wizard prompts. The response file should contain the same parameters as the wizard, such as the installation directory, database name, port number, and passwords for the administrator (sys) and system (system) users.

The response file is usually named "response.rsp" and is stored in the same directory as the installer. In silent installation mode, we need to use the "-silent" option on the command line to specify the use of the response file as the installation parameter reference.

For example, the following command will run the Oracle installer to install the database using the settings defined in the response.rsp file: ./runInstaller -silent -responseFile /path/to/response.rsp

Before using the response file to install the database, we need to edit the response.rsp file according to actual needs. The following are some parameters that may need to be configured:

• ORACLE_HOME: The installation root directory of Oracle products.
• ORACLE_BASE: The root directory where the system runs Oracle products.
• UNIX_GROUP_NAME: Create system users and groups and associate the user with the group.
• INSTALL_DB_AND_CONFIG: Specify the Oracle product to be installed and configured. Select the database installer here.
• oracle.install.db.DBA_GROUP: Specify the name of the database administrator user group.
• oracle.install.db.BACKUPDBA_GROUP: Specify the backup database administrator user group name.
• oracle.install.db.DGDBA_GROUP: Specifies the name of the data protection administrator user group.
• oracle.install.db.KMDBA_GROUP: Specifies the key management administrator user group name.
• oracle.install.db.OSDBA_GROUP: Specifies the operating system (UNIX) administrator user group name.
• oracle.install.db.OSOPER_GROUP: Specifies the name of the operating system (UNIX) operator user group.
• oracle.install.db.CLUSTER_NODES: Specifies the global name (GNS) of the Oracle instance to be installed.

After you finish editing the response file, save it to an appropriate location and execute the silent installer. The installer will run directly using the installation parameters defined in the response file and will not respond to user input until the installation is complete.

In short, by using the silent installation mode, Oracle database installation becomes more automated and convenient, making the installation process smoother and more efficient.
