Cause

Java 11 is installed on the system when applying the 1.1.14-1 DPC OS update, but the update does not make it the default Java versions.When you run the DPC upgrade to 19.9, it changes the default Java version to 11. For some reason, the OS update caused the Java version to update to Java 11. DPC 19.8 and earlier requires Java 8 to run.This is what is causing this error.

Resolution

To address this issue, do the following: Log in to DPC CLI using SSH or PuTTY as admin and su - to root.Run the following command: sudo update-alternatives --config java There are two choices for the alternative Java (providing /usr/bin/java).

This sets the system to use Java 8Restart DPC services with the following command: ~admin/bin/dpc restart Reach out to Dell Support if you have any questions or issues with this procedure.
