This error occurs while running oracle database auto start script.
chkconfig --level 345 dbora on
service dbora does not support chkconfig.
Edit the dbora script. There is a typo in chkconfig: -20 80. It has a space in front of 20. e.g;
chkconfig: - 20 80
Now you can use the command
chkconfig --level 345 dbora on
