Migrating to OpenJDK 1.8.0

Proceed as follows to switch between the different JVMs:

1. Install or update the package:

   • RHEL: yum install java-1.8.0-openjdk-headless

   • SLES: SUSE no longer provides Oracle/Sun Java in the distribution or through the update channels.

     1. Use YaST > Software > Software Management and remove all previous versions of Java, for example, java-1_6_0-sun, icedtea-web. Do not remove the openJDK version of Java if you have it installed. This is required for Java functionality in LibreOffice.
     2. Download and install the original JDK from the download site java.com for Linux x64 RPM.

2. Optional: Execute the update-alternatives --config java command and select "OpenJDK 1.8.0".

3. Make sure that the JAVA_HOME system variable points to "OpenJDK 1.8.0". Therefore, adapt the conf/env.conf file of nevisIDM by setting the JAVA_HOME variable to the correct OpenJDK.

   For example:

   JAVA_HOME=/etc/alternatives/jre_1.8.0

   Point to a path without a full version number to simplify upgrades of the installed OpenJDK package.

4. Restart nevisIDM.
