Issue/Introduction

How to update the installed version of Java JRE for all UIM hubs?

Environment

• Release: DX UIM 20.4* or 23.4*
• Component: java_jre

Cause

• Java runtime environment update

Resolution

Follow these steps to update the Java runtime environment in UIM

---

1. Download the latest java_jre probe from the Support Archive (support.nimsoft.com)

2. RT-click and import the java_jre package into the local archive on the Primary hub

3. Drag and drop the imported package onto the robot to change the Java runtime environment

4. Verify that the update is complete by checking that the following values are updated to <new_java_folder>
    (after deploying a new java_jre version a new folder will be created - you need to use the new directory's name)

     robot.cfg file Environment variables:

                 NIM_JRE_HOME = jre/<new_java_folder>
                 NIM_JRE_HOME_1_8 = jre/<new_java_folder>

5. Restart the robot
    Restarting the robot ensures that all the Java probes deployed on the robot will use the latest jre version

6. Manually delete the old java_jre folder (for example: jre8u382b05) located in the directory <UIM_Installation>\Nimsoft\jre in all the robots

    As of 5 Dec 2025, the latest jave_jre is version 3.0.0 which is java jre8u472b08.
   
    In this example the highlighted folders and files may be deleted as they are not used.
