Oracle Enterprise Manger Agent not working, making it not possible to configure EM DB console

I have installed oracle database 11gR2 on Oracle linux 7.2. However, oracle enterprise manager was not working. I tried to figure our what was wrong and a long search, i came across a blog that suggested that I should reconfigure EM. using the following command

#emca -config dbcontrol db -repos recreate

This command started well, but failed at the point where it securing the DB console with the following error.

Error securing Database Control, Database Control has been brought up in non-secure mode. To secure the Database Control execute the following command(s): 

 1) Set the environment variable ORACLE_SID to orcl    

 2) /u01/app/oracle/product/11.2.0.4/db_1/bin/emctl stop dbconsole   

 3) /u01/app/oracle/product/11.2.0.4/db_1/bin/emctl config emkey -repos

 4) -sysman_pwd < Password for SYSMAN user            /u01/app/oracle/product/11.2.0.4/db_1/bin/emctl secure dbconsole
  -sysman_pwd < Password for SYSMAN user >    

 5) /u01/app/oracle/product/11.2.0.4/db_1/bin/emctl start dbconsole

 To secure Em Key, run /u01/app/oracle/product/11.2.0.4/db_1/bin/emctl config       emkey -remove_from_repos -sysman_pwd < Password for SYSMAN user >
 Aug 3, 2016 3:48:30 PM oracle.sysman.emcp.EMConfig perform

The problem lies in executing step (4) above. Each time i run command of step 4, i get the following error

*[04-08-2016 12:00:39] USERINFO ::DBCONSOLE already stopped...   Done.
[04-08-2016 12:00:39] USERINFO ::Failed to stop agent...*

The command emctl stop agent is not recognised as well as emctl start agent

My agent version is 10.2.0.4.0

my DB control version is 11.2.0.1.0

I cant stop nor start the agent. this prevents me from proceeding with whatever help in I get on the internet because it requires starting and stopping the agent.

When i run the command *#emctl status agent*, i get the following out put

*Oracle Enterprise manager 11g DB Control version 11.2.0.1.0

Copyright (C) 1996, 2009 Oracle Corporation. All right reserved.*

Please I have been trying to solve this for the pas 5 days, but i always get stuck by when there's any step involving starting or stopping the agent. So i guest my main problem is the agent.

To enable Oracle Enterprise Manager on Oracle Linux 7.x you need to upgrade the Oracle Database Server and Oracle Database to version 11.2.0.4.0. After that the Oracle patch "19692824: DBCONTROL is not coming up on OEL 7" must be installed to upgrade the version of OEM Agent.

Finally you can enable OEM with HTTPS using the command:

emca -config dbcontrol db -repos create

Note: The patch 19692824 is not compatible with Oracle Database Server 11.2.0.3.0
