Installing or updating Oracle OpenJDK

Oracle OpenJDK and Tomcat are prerequisites for SunSystems and must be maintained with the latest performance and security enhancements. Windows environment variables are used by SunSystems to establish the location of these local installations.

You must use the latest version to ensure your environment has the most recent security updates for Oracle Java Development Kit:

  1. Download the zip file for Windows/x64 from https://jdk.java.net/18/
  2. Unzip the file into C:\SunSystemsPlatform or an equivalent folder and update the SUNSYS_JAVA_HOME64 environment variable with this location.
    Note: 
    • If you are updating Java on an existing installation, then you must run Restart Services after updating the Java environment variable.
    • If you are installing SunSystems, then SUNSYS_JAVA_HOME is set during the installation process.
