Java Update

The Java Update feature enables you to change the Java Runtime Environment (JRE) used by PowerChute to any other JRE already installed on your system. Follow the steps below to update the Java version used by PowerChute.

1. Download a valid JRE on your system. JREs can be downloaded from the AdoptOpenJDK website.

   PowerChute supports AdoptOpenJDK 11. You can only update the Java version used with PowerChute to a 64-bit JRE. The Java versions supported by PowerChute are available in the Operating System Compatibility chart.

    

2. Navigate to the PowerChute installation directory, and create a new folder called “Updates”. If the default installation directory was chosen during installation, this location will be:

   1. • C:\Program Files\APC\PowerChute\Updates for Windows systems

      • /opt/APC/PowerChute/Updates/ for Linux systems

3. Copy the Java file downloaded in Step 1 above to the Updates directory.

4. Navigate to the About screen in the PowerChute UI (Help > About). In the Java Update Available field, the downloaded Java file will be listed in a drop-down box.

5. Select the Java version you want to update PowerChute to use from the drop-down box, and click Upgrade.

6. A confirmation dialog will appear. Click OK.

7. Another dialog will appear and PowerChute restarts. Wait 2-3 minutes for the Java version to successfully update.

8. When the PowerChute service restarts, refresh your browser and navigate to the About screen. The Java Version field will be updated to show the new Java used by PowerChute.
