Automatic start on Linux Systems with systemctl

Some newer versions of Linux, as there are RHEL 7 and CentOS 7.x, uses the systemctl to start applications at boot.

To enable the Uniface License server DLM to start using systemctl take the next steps.

1. Create a new service unit file at /etc/systemd/system/dlm.service with content:

       [Unit]
       Description=Uniface DLM services
       After=network.target
   
       [Service]
       Type=oneshot
       ExecStart=/opt/Compuware/dlm/Linux/amd64/cpwr -start
       ExecStop=/opt/Compuware/dlm/Linux/amd64/cpwr -stop
       SuccessExitStatus=0 1
       TimeoutStartSec=0
       RemainAfterExit=yes
   
       [Install]
       WantedBy=default.target
   
   

   Note: change the path to the cpwr process name to your actual path if it deviates from the default.
   

   
   

2. make process executable

    # chmod 755 dlm.service

3. Reload the systemd process to consider newly created dlm.service

   # systemctl daemon-reload

4. Enable the service

   # systemctl enable dlm.service

5. Test systemctl start

       # systemctl start dlm
       # ps -ef | grep cpwr

6. Test systemctl stop

       # systemctl stop dlm
       # ps -ef | grep cpwr

7. Reboot system to test

       # reboot
       # ps - ef | grep cpwr
