You can face very strange problems after installing agents that is

1) The Agent will not connect to the OMS

2) You will not be able to secure the Agent.

If you see the status of agent you will see something like this,

oracle@host # ./emctl status agent

And if you try to secure agent you will get something like this

oracle@jdb1p # ./emctl secure agent

Enter Agent Registration password : 

Agent successfully stopped...   Done.

Securing agent...   Started.

Requesting an HTTPS Upload URL from the OMS...   Failed.

The OMS is not set up for Enterprise Manager Security.

Now the cause is that the URL for the OMA upload is not set properly in emd.properties file.

You have to fix

REPOSITORY_URL= 

and

emdWalletSrcUrl=

after making changes in URL you can secure your agent using 

emctl secure agent

Always first make sure that you set your home properly also the path of emdroot
