After I post about how to install Oracle Enterprise manager (em12c) today I will talk how to deploy em12c agent

There are two methods to do that

1) Configuring Automatic Discovery 2) Adding targets manually

I will describe the both :) each one separately.

Before deploy you need to decide if you want to use Oracle user or root user the below steps you have to do before using oracle:

[root@em12c ~]# vi /etc/sudoers

And change and add the following lines:

Comment this line:

#Defaults requiretty

Add the below line

oracle ALL=(ALL) ALL

And remove ! From this line:

Defaults visiblepw

Now On em12c there’s something called privilege delegation

Privilege delegation allows a logged-in user to perform an activity with the privileges of another user. Sudo and PowerBroker are privilege delegation tools that allow a logged-in user to be assigned these privileges. These privilege delegation settings will be used for all provisioning and patching activities on these hosts.
