OEM 13cR3: Install Agent Using Silent Method

In this blog I am going to cover method of installing OEM agent using the silent method. 
There are 2 silent methods, but, the one which prefer is the AgentPull method. 

This can be useful specially in cases when you do not have password to oracle user and you use sudo to access it, but still want to do the installation. 

So, here is how it goes 

Step 1 : 
Download the agent Image (For Linux / Unix)

$ wget https://<hostname:port of oms>/em/install/getAgentImage --no-check-certificate
$ mv getAgentImage AgentPull.sh
$ chmod u+x AgentPull.sh

Step 2 :
Verify your required platform is present or not
$ ./AgentPull.sh -showPlatforms

Step 3 :
Create rsp file with name agent.properties
LOGIN_USER=sysman
LOGIN_PASSWORD=welcome
PLATFORM="Linux x86-64"
AGENT_REGISTRATION_PASSWORD=wel246come
AGENT_BASE_DIR=/u01/app/oracle/agent

Step 4 : 
Install the agent
$ /tmp/AgentPull.sh RSPFILE_LOC=/tmp/agent.properties AGENT_BASE_DIR=/u01/app/oracle/agent

(Log files removed for brevity)

And once it goes on the installation will complete.
Next you can go to OEM console and Add targets
