One of the reasons could be that the password for the SYSMAN user is expired. However, changing the password alone will not solve this issue. Several additional steps are required in order to make Oracle Enterprise Manager connect:

Before you start: Verify that ORACLE_HOME, ORACLE_SID environment variables are set. – If not, set them using as environment variables or open a command line and type SET ORACLE_SID=<The database SID>

1. Stop the dbconsole: emctl stop dbconsole (dos and Unix) or using the windows services stop the OrcleDBConsole<The database SID>.

2. Connect to the database as a user with DBA privilege with SQL*Plus
and run the following command:

alter user sysman identified by <the new password> ;

3. Verify that the new password works
SQL> connect sysman/<the new password>

4. Go to ORACLE_HOME/<HostName_SID>/sysman/config and save a backup of the emoms.properties file.

a) Open the file emoms.properties and search for:
oracle.sysman.eml.mntr.emdRepPwd=<some encrypted value>

Replace the encrypted value with the new password value

Search for oracle.sysman.eml.mntr.emdRepPwdEncrypted=TRUE
and change TRUE to FALSE

c) Save and close emoms.properties

5. Restart the dbconsole:

emctl start dbconsole (dos and Unix) or using the windows services start the OrcleDBConsole<The database SID>.

6. Open emoms.properties again and Search for:
a)oracle.sysman.eml.mntr.emdRepPwd=
verify that the password is encrypted

oracle.sysman.eml.mntr.emdRepPwdEncrypted=
verify that the value is set to TRUE

7. Refresh Oracle Enterprise Manager
