On a 64-bit system, you can download either the 64-bit or the 32-bit version of the Java platform. See Oracle JDK 8 and JRE 8 Certified System Configurations for information about supported platforms, operating systems, and browsers. In addition, you can check which specific RPM package provides the java files: rpm -q -whatprovides java System Requirements for Installing JDK on Linux Platforms Using the java -version command, you can confirm the default (recently installed) JDK version.

Java commands such as java, javac, javadoc, and javap can be called from the command line. After installation, the alternatives framework is updated to reflect the binaries from the recently installed JDK. The JDK installation is integrated with the alternatives framework. System Preferencesīy default, the installation script configures the system such that the backing store for the system node of Java Preferences API (the Java package) is configured in the /etc/.java/.systemPrefs directory.

You must log in with root credentials to install or update JDK. Note: If you install an older version of a JDK when the newer version of the same feature family already exists, an error is displayed, prompting you to uninstall a newer JDK version if an older version has to be installed. Additionally, a symbolic link named /usr/java/jdk1.8.0- arch pointing to the installation directory is created for backward compatibility.

If you attempt to install JDK 8u381 after JDK 8u 371 is installed, the installer uninstalls JDK 8u371 and installs JDK 8u381.Īll versions of JDK of the same feature release are installed in /usr/lib/jvm/jdk-1.8-oracle- arch, where arch is either 圆4, aarch64, or x86, depending on the architecture of your system. For example, you can't install JDK 8u371 and JDK 8u381 simultaneously. If you try to install the newer version of the same feature release while the older version exists, the installer uninstalls the older version and installs the new version. You can install only one version of JDK of the same feature release. General Notes About Installing the JDK on Linux Platforms from RPM Packages If this functionality of the JDK is required, you need to manually configure it by making sure either the /etc/.java/.systemPrefs or jdk-1.8-oracle- arch/.systemPrefs directory exists.

Installing the JDK from archive files doesn't configure the backing store for the system node of Java Preferences API (the Java package). Ensure that you rename the old directory if it contains files that you would like to keep.

If you install the software in a directory that contains a subdirectory named jdk-1.8-oracle- arch, the installer overwrites files of the same name in that directory. If you do not have the root access, either install the JDK in your home directory or a subdirectory for which you have write permissions. If you install JDK in a specific location such as /opt, you must log in with root credentials to gain the necessary permissions. Installing the JDK automatically creates a directory named /usr/lib/jvm/jdk-1.8-oracle- arch, where arch is either 圆4 (64-bit systems), aarch64 (64-bit ARM systems), or x86 (32-bit systems), depending on the architecture of your system.
