To include external native libraries: Copy the native libraries into a system library directory, e. You can verify that the directory is included in Java's System Property " java. This technique allows you to install a private version of the JDK for the current user into any location, without affecting other JDK installations.

This technique allows you to perform a system-wide installation of the JDK for all users, and requires root access. Note that this is a legacy install option. You can install a JDK archive binary in any location that you can write to. These instructions install a private version of the JDK. Before the file can be downloaded, you must accept the license agreement. The archive binaries can be installed by anyone in any location that you can write to.

The JDK is installed in a directory called jdk1. For example, for the JDK 8 update 1 release, the directory would be named: jdk1. The JDK documentation is a separate download. Use these instructions if you want to use the pkgadd utility to install the JDK. This technique allows all users on your system to access Java.

You can use the roles 1 command to determine whether you are able to assume the root role. You can skip this step if you intend to install the JDK in a non-default location.

Starting with version 8u40, the JDK installation is integrated with the alternatives framework and after installation, the alternatives framework is updated to reflect the binaries from the recently installed JDK.

Java commands such as java , javac , javadoc , and javap can be invoked from the command line. Using the java -version command, users can confirm the default recently installed JDK version. In some versions of the alternatives framework, certain link names in these groups were duplicated, which resulted in installation failures. All links unique to the javac group are moved into the java group, but the set of symbolic links registered by the installer are not changed; only the duplicated links have been dropped.

The implication of this change is that if you install JDK 8u and JDK 8u or older versions and uninstall JDK 8u, the symbolic links from the java group that are managed by the alternatives framework will be deleted.

To restore the deleted links, run the following command:. Installation of these RPMs on Linux distributions other than OL gives a warning message indicating that security validation of the package fails. This indicates that the public key used to sign this RPM needs to be installed in the system.

A sample warning message and the public key installation steps are as follows:. Installing the software automatically creates a directory called jdk1. If you do not have root access, simply install the JDK into your home directory, or a subdirectory that you have permission to write to.

If you install the software in a directory that contains a subdirectory named jdk1. Please be careful to rename the old directory if it contains files you would like to keep. By default, the installation script configures the system such that the backing store for system preferences is created inside the JDK's installation directory. If the JDK is installed on a network-mounted drive, it and the system preferences can be exported for sharing with Java runtime environments on other machines.
