When I tried to upgrade CAMM on my PM console I got following error.
Installer has detected an unsupported version of java. CAMM requires java Runtime Environment version 11. Please run this installer with java version 1.11
The installer cannot run on your configuration. it will now quit
Dx NetOps Mediation Manager 22.2.x
Java 11 is a requirement
You can run yum install -y java-11-openjdk, or work with your linux admin to install Java 11 and rerun the upgrade
