I am looking at the Linux agent installation documentation (below) and it applies to v6 of Linux (configuring a script in /etc/init.d).
Installed SEM version = 2019.4
Install the SEM Agent on Linux and Unix
It also notes:
To configure the SEM Agent to start automatically on boot, add /etc/init.d/swsem-agent
(or swsem-agent) to your list of startup scripts.
Does the installation provide a default template script?
Thanks,
Randy
