Hello,

do exist a possibility to execute the playbook on a machine, that isn’t recognizedin the host file?

For example

- **ansible-playbook oracle-db12c-installation.yml --extra-vars “variable\_hosts=10.92.0.40”**

yes, just specify it as your 'new hosts file' or inventory:

ansible-playbook oracle-db12c-installation.yml --extra-vars -i '10.92.0.40,'

assumes playbook is using `hosts: all`
