Cannot run a script as root user

Dear all,

I am facing an issue while I try to run the appian status.sh script  as root user despite the ownership is root.

I am getting the following error:

ERROR: JAVA_HOME is not set and no 'java' command could be found in your PATH.

Please set the JAVA_HOME variable in your environment to match the
location of your Java installation.

Any idea of how I can run it as root?

Thanks beforehand.

Kind regards,
