Oracle Grid Control Agent Problems

-->
Oracle Grid Control Agent Problems
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
Oracle Enterprise Manager 10g Release 10.2.0.2.0.

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
