> x oracle  
> y db  
> x prod

I assume the x should be the hostname, and the second column should be  
the line in /etc/hosts.allow?

> how can i do it for huge number of nodes ?

You put more than one host in the "- hosts:" line? 😉

Seriously, put the x=oracle values in the host\_vars for each hosts.  
Call it something describing, hostname\_in\_etc\_hosts\_allow and set it  
to oracle on host x (host\_vars/x/main.yml), and to db on host y.

Then put the variable hostname\_in\_etc\_hosts\_allow in your task:

- name: Add a word in remote file  
&nbsp;&nbsp;hosts: temp  
&nbsp;&nbsp;remote\_user: xx  
&nbsp;&nbsp;sudo: yes  
&nbsp;&nbsp;tasks:  
&nbsp;&nbsp;&nbsp;&nbsp;- name: edit cron.allow  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;lineinfile:  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;destfile: /etc/cron.allow  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;line: '{{ hostname\_in\_etc\_hosts\_allow }}'

BTW: "sudo: yes" is being substituted by "become: yes" and  
"become\_method: sudo" for quite some time, might throw an error in  
future releases.
