We would like to upgrade Java (JDK) with Clarity to a higher patch level, how do we proceed? 

Environment

Release : Any

Resolution

1. Determine a supported Java version to use with your Clarity version
2. Install the Java version on your server. You do not have to uninstall the old version
3. Ensure the user running Clarity has full permissions over Java folder, including execute permissions
4. Correct the environmental variables for JAVA_HOME and PATH to point to the new Java version folder
5. In Clarity, stop all services
   service stop all
6. Open properties.xml and update the path for java home to point to the new Java, example:
    <java home="/opt/java/jdk-11.0.16+8"
7. Start back the services
   service start all
8. Repeat on any other servers in cluster
