Not able to start Em Console for Oracle 11g in Linux 6.1

Question

I have a RedHat Linux 6.1 Laptop. I successfully installed Oracle 11g in my laptop and configured the DB.
Post Installation everything was working fine and I could open the EM console.
After stopping the DB, I am not able to bring up the em console. Notice the below error

======================================
One of the links suggested it could  be because of sys and sysman users being locked. I ran the "alter user  sysman  account unlock;" command and unlocked it.
BEFORE Unlock

Hi,
As you have mentioned that the sysman account was locked I would recommend to change the sysman password as per below doc to ensure the password is consistent at both config file and DB level
How To Change the Password of the Database User Sysman (DB Control Repository Schema) (Doc ID 259379.1)
Then try accessing the DBcontrol using below URL
http://localhost:1158/em/console
