I received the above error when try to start Oracle Enterprise Manager (OEM)
And the reasons might be sysman,dbsnmp password expired or lock due to user password setting The simple steps to unlock the sysman user.
STEP 1: Sign in SQLPlus as sysman in my case only password expired as shown in below image and if remember the old sysman password and accoring
to password setting if allow you to change the
password then change the password
else ,
Sign in as SYSDBA and run the below sql
ALTER USER SYSMAN IDENTIFIED BY NEW_PASSWORD ACCOUNT UNLOCK;
STEP 2: Once you change the password and unlock the sysman password try to log in to OEM
STEP 3: Try to log in as sys as sysdba ,and once able to log in this will prompt for all user expired password and new password ,assign the new password for expired user password .
STEP 4: Log out and log in again and enjoy working with OEM
