[Oracle DataBase Server 12.1 installation on Oracle Linux 6.7]: Autostart only packages what nedeed

Next command will disable autostart all packages.

# for i in $(chkconfig --list | grep '3:on\|4:on\|5:on' | awk {'print $1'}); do chkconfig --level 345 $i off; done

Check what packages will start after reboot automatically

# chkconfig --list | grep '3:on\|4:on\|5:on'  |awk '{print $1}' | sort

After that, we will start only packages what we really needs:

# {
chkconfig --level 345 network on
chkconfig --level 345 sshd on
chkconfig --level 345 ntpd on
}

# {
chkconfig --level 345 auditd on
chkconfig --level 345 messagebus on
chkconfig --level 345 netfs on
chkconfig --level 345 sysstat on
chkconfig --level 345 crond on
chkconfig --level 345 xinetd on
}

Later we will add:

# chkconfig --level 345 startupOracleDatabase12R1 on

Check what ssh package will run after reboot

# chkconfig --list | grep ssh

Try to reboot server to check what all correct.

# reboot
