Installing Liberty using Installation Manager

You can install WebSphere® Application Server Liberty using IBM® Installation Manager Version 1.8.5 or later. Installation Manager provides managed installations, allows for in-place updates, and is the same tool that is used to install many other IBM products.

About this task

[17.0.0.3 and later]Important: Support for using Java™ SE 6 with WebSphere Liberty ended in September 2017. The Liberty kernel was recompiled for 17.0.0.3. Beginning with 17.0.0.3, the Liberty kernel no longer runs with Java SE 6. If you continue to use Java SE 6 on earlier releases after the end of support date, you might expose your environment to security risks.

Java SE 8 is the recommended Java SDK because it provides the latest features and security updates. As an alternative to installing Java SE 8, you can install another supported Java SDK version.

Installation Manager is a general-purpose software installation and update tool that runs on a range of computer systems. You can use the Installation Manager graphical user interface (GUI), command line, response files, or console mode as dependent on your operating system.

New: Liberty now follows a continuous delivery process with a new fix pack numbering scheme. For more information, see What is new in this release of Liberty.

The documentation primarily covers installing the Liberty product. You can also install supplemental offerings to use with Liberty, such as IBM HTTP Server or the Web Server Plug-ins. For information about installing these offerings, see the installation documentation for WebSphere Application Server traditional.
