Setting the JAVA_HOME variable for Liberty collective members and controllers

All Liberty collective members must have a Java™ Runtime Environment (JRE) installed that meets the minimum requirements of the Liberty server. After a JRE is installed on the host computer, you can set the JAVA_HOME variable so that the Liberty operation can locate the JRE.

About this task

In order for the collective controller to perform remote operations on Windows members such as starting or stopping a member server, the collective controller must run with an IBM® JRE. Third-party JREs do not contain the required security classes. You can get a JRE that supports Liberty products and SSL from Installation Manager offerings or developerWorks®:

You can set the JAVA_HOME variable in operating system settings or at a command line. Setting set the JAVA_HOME variable enables remote operations to locate the JRE.
