ace.service

[Unit]
Description=Startovanje ACE-a
After=network.target

[Service]
ExecStart=/etc/init.d/ibmace.sh start
ExecStop=/etc/init.d/ibmace.sh stop
Type=forking
KillMode=none
LimitNOFILE=10240
LimitNPROC=4096

[Install]
WantedBy=multi.user.target

I don't know what Type=forking means and below components so maybe need to edit that. When i created script and service and put script in /etc/init.d/, create sym link to rc*.d(all), put S99 and K10 for starting and stopping. In bash_profile added this two lines and do the source

export PATH

    . /opt/ace-12.0.4.0/server/bin/mqsiprofile
    . /opt/mqm/bin/setmqenv -s

After reboot, in pom.txt it's show like it's started, but when i do systemctl status ace.service output is

[root@ct-tre-iib ~]# systemctl status ace.service
● ace.service - Startovanje ACE-a
   Loaded: loaded (/etc/systemd/system/ace.service; enabled; vendor preset: disabled)

Also i have doubts about these two directories.

drwxr-xr-x. 10 root root  133 Oct 12 17:59 ace-12.0.4.0
dr-xr-xr-x. 21 mqm  mqm  4096 Jun  7 21:23 mqm

Maybe i need to change owner from root user to mqm in ace. What should i do next? Anyone?
