Yum-cron service execution

NethServer release 7.6.1810 (final)
Module: yum-cron 3.4.3 161.el7.cento

Hi everyone, can anyone post the status of the yum-cron service?
I noticed that in / var / lock / subsystem / yum-cron is not present as in the past. I would just like to make a comparison.
This is my server’s:

● yum-cron.service - Run automatic yum updates as a cron job
Loaded: loaded (/usr/lib/systemd/system/yum-cron.service; disabled; vendor preset: disabled)
Active: inactive (dead)

And this is the configuration:
yum-cron = service
applyUpdate = no
customMail =
download = no
messages = yes
randomWait = 360
status = enabled

Thank you all !

   CGroup: /system.slice/yum-cron.service

IIRC, this is default config with just one change (download):

# config show yum-cron 
yum-cron=service
    applyUpdate=no
    customMail=
    download=yes
    messages=yes
    randomWait=360
    status=enabled

Hi, by running yum-cron manually I read this: ● yum-cron.service -

Loaded: loaded (/usr/lib/systemd/system/yum-cron.service; disabled; vendor preset: disabled)
Active: active (exited) since Fri 2019-05-31 11:28:41 CEST; 5min needle
Process: 23570 ExecStart = / bin / touch / var / lock / subsys / yum-cron (code = exited, status = 0 / SUCCESS)
Main PID: 23570 (code = exited, status = 0 / SUCCESS)
How do I activate the service automatically?
Also if I see config show yum-cron and change parameters (eg status enabled or disabled) what signal do I have to do?
Thank you

You can try with:

systemctl enable yum-cron

Don’t know if there’s a specific signal-event.

thank you so much .
