AutoStart/Shutdown Oracle and Listener on RHEL7/OL7 using systemd

1. Create unit file in the /etc/systemd/system/ directory and make sure it has correct file permissions. Execute as root:
[root@em12c ~]#  touch /etc/systemd/system/Oracle_Listener_LISTENER.service 
[root@em12c ~]#  chmod 664 /etc/systemd/system/Oracle_Listener_LISTENER.service
2. Add the following content to the file: /etc/systemd/system/Oracle_Listener_LISTENER.service
[Unit]
Description=Oracle Listener (LISTENER)
After=network.target
[Service]
Type=forking
PIDFile=/home/oracle/scripts/LISTENER.pid
ExecStart=/bin/su - oracle -c "/home/oracle/scripts/lsnrstart.sh LISTENER"
ExecReload=/bin/su - oracle -c "/home/oracle/scripts/lsnrshut.sh LISTENER;/home/oracle/scripts/lsnrstart.sh LISTENER"
ExecStop=/bin/su - oracle -c "/home/oracle/scripts/lsnrshut.sh LISTENER"
[Install]
WantedBy=multi-user.target
3. Execute the following commands to reload the configuration and start the custom service:

[root@em12c ~]# systemctl daemon-reload
[root@em12c ~]# systemctl start Oracle_Listener_LISTENER.service [root@em12c ~]# systemctl enable Oracle_Listener_LISTENER.service

4. Create unit file in the /etc/systemd/system/ directory and make sure it has correct file permissions. Execute as root:
[root@em12c ~]#  touch /etc/systemd/system/Oracle_Instance_orcl.service [root@em12c ~]#  chmod 664 /etc/systemd/system/Oracle_Instance_orcl.service
5. Add the following content to the file: /etc/systemd/system/Oracle_Instance_orcl.service
[Unit]
Description=Oracle Instance (orcl)
After=network.target
Wants=Oracle_Listener_LISTENER.service
[Service]
Type=forking
PIDFile=/home/oracle/scripts/orcl.pid
ExecStart=/bin/su - oracle -c "/home/oracle/scripts/dbstart.sh orcl"
ExecReload=/bin/su - oracle -c "/home/oracle/scripts/dbshut.sh orcl;/home/oracle/scripts/lsnrstart.sh orcl"
ExecStop=/bin/su - oracle -c "/home/oracle/scripts/dbstart.sh orcl"
[Install]
WantedBy=multi-user.target

6. Execute the following commands to reload the configuration and start the custom service:

[root@em12c ~]# systemctl daemon-reload 
[root@em12c ~]# systemctl start Oracle_Instance_orcl.service
[root@em12c ~]# systemctl enable Oracle_Instance_orcl.service
7. Check the service status:
[root@em12c ~]# systemctl |grep -e Oracle -e DESCRIPTION
