20 Installing the JDK and the JRE with a Configuration File

You can use a configuration file to standardize JDK and JRE installations and specify options that are not available on the command line. An installer configuration file is an alternative to, and extension of, options specified on the installer command line.

Note: Windows, macOS, Linux, and Solaris command-line installers support the configuration file, but not every operating system supports all configuration file options.

This page has these sections:

"System Runtime Configuration File"

Using a Configuration File

If you are installing the JRE or JDK on Windows, use the INSTALLCFG command-line option to specify a configuration file:

installer INSTALLCFG=configuration_file_path

installer is the installer base file name, for example, jre-8u211-windows-x64.exe or jdk-8u211-windows-x64.exe.
configuration_file_path is the path to the configuration file.

If you are installing the JRE or JDK on Solaris, Linux, or macOS, create a configuration file name named /etc/java/config/jre-install.properties. When you launch the JRE or JDK installer, it looks for a configuration file with this specific path and name.

Configuration File Options

The following table lists the installer configuration file options that apply for each operating system.

Note:

You may substitute the value Enable for 1 and the value Disable for 0.

You may use the same options at the command line when running the JDK or JRE Windows Offline Installer. See "Command-Line Installation".

Table 20-1 Configuration File Options

Option	Operating Systems	Values	Description	Default Value	Saved in Runtime Configuration File?
`AUTO_UPDATE=`	Windows, macOS	`Enable`, `Disable`	Enables the auto update feature.	`Enable`	yes
`DEPLOYMENT_RULE_SET=`	Windows, macOS, Linux, Solaris	path	Specifies the path and file name of your organization's deployment rule set. See Deployment Rule Set in the Java Platform, Standard Edition Deployment Guide.	None	yes
`EULA=`	Windows	`Enable`, `Disable`	Prompts the user to accept the end-user license agreement (EULA) if a Java applet or Java Web Start application is launched.	`Disable`	yes
`INSTALL_SILENT=`	Windows	`Enable`, `Disable`	Performs a silent (non-interactive) installation.	`Disable`	yes
`INSTALLDIR=`	Windows	path	Specifies the folder/directory into which the files are installed. For Windows, this will only work for first time install of a family. Linux and Solaris use operating system tools for this purpose and installation directory relocation will be handled by operating system tools (for example: `rpm --prefix=path`)	Operating system default path	no
`INSTALLDIRPUBJRE=`	Windows	path	When installing the JDK, this option specifies the folder where the public JRE is installed. When specifying this option, you must also specify which folder where the JDK is installed with the `INSTALLDIR` option.	Operating system default path	No
`NOSTARTMENU=`	Windows	`Enable`, `Disable`	Specifies that the installer installs the JDK or JRE without setting up Java start-up items.	`Disable`	no
`REBOOT=`	Windows	`Enable`, `Disable`	If disabled, prompts you to restart your computer after installing the JDK or JRE. However, in most cases, the installer does not need to restart your computer after installing the JDK or JRE.	`Enable`	no
`REMOVEOUTOFDATEJRES=`	Windows	`0`, `1`	Note: Applicable to online and offline installers only (files and wrappers). Enables uninstallation of existing out-of-date JREs during JRE install. Using `REMOVEOUTOFDATEJRES=0` leaves all out-of-date Java versions on the system. Using `REMOVEOUTOFDATEJRES=1` removes all out-of-date Java versions from the system. For example, running `jre1.8.0_60.exe /s REMOVEOUTOFDATEJRES=1` will remove all JREs below the security baseline. JREs above the security baseline will not be uninstalled.	`0`	no
`STATIC=`	Windows	`Enable`, `Disable`	Performs a static installation (see "Static Installation").	`Disable`	no
`USAGETRACKER_CFG=`	Windows, macOS, Linux, Solaris	path	Specifies the path and file name of the Java Usage Tracker properties file. See Java Usage Tracker Guide.	None	yes
`WEB_ANALYTICS=`	Windows	`Enable`, `Disable`	Enables or disables the installer to send installation-related statistics to an Oracle server.	`Enable`	yes
`WEB_JAVA_SECURITY_LEVEL=`	Windows, macOS, Linux, Solaris	`H` (high), `VH` (very high)	Configures the installation's security level for Java applications running in a browser or run with Java Web Start.	`H`	no
`WEB_JAVA=`	Windows, macOS, Linux, Solaris	`Enable`, `Disable`	Configures the installation so downloaded Java applications are, or are not, allowed to run in a web browser or by Java Web Start.	`Enable`	no

Sample Configuration File

The following is a sample JRE configuration file for Windows. It specifies the following:

Perform a silent install.
Install the JRE in the directory C:\java\jre.
Set the security level for unsigned Java applications running in a browser to very high.

Example 20-1 Sample Configuration File for Windows

INSTALL_SILENT=Enable
INSTALLDIR=C:\java\jre
WEB_JAVA_SECURITY_LEVEL=VH

System Runtime Configuration File

After installing the JDK or JRE with a configuration file, the installer saves the file (with a subset of options used during install) in one of the following locations in your computer, depending on your operating system:

Windows: %ALLUSERSPROFILE%\Oracle\Java\java.settings.cfg

The value of the environment variable %ALLUSERSPROFILE% is typically C:\ProgramData.
Solaris and Linux: /etc/Oracle/Java/java.settings.cfg
macOS: /Library/Application/Support/Oracle/Java/java.settings.cfg
