Can't login em, execute emca-config dbcontrol db do not know always default 1522 port number, helpless, Google some, from the second step below to start execution ... (My monitor is fine)

1. Open the net config Assistant in the Oracle Configuration tool, select "Listener Configuration", Next, then "reconfigure", next, take a closer look at the parameters of each step configuration is OK.
2. Use the "Emca-deconfig Dbcontrol DB" command on the command line to remove the configuration
3. Delete repository using "emca-repos drop" command
Note: 2nd, 3 steps to do, or in the re-installation of EM will be reported "Ora-20001:sysman already exists." Error caused the installation to fail.
4. Use "Emca-config dbcontrol db-repos Create" command for creating EM.
After the above steps have been completed successfully created a good EM, click on the Start menu in the Oracle folder in the database CONTROL-ORCL connection can be normal access to EM.
It is important to note that the address of the access EM was https://localhost:1158/em when I first installed Oracle, the port number is 1158, and now the port number behind the address link after I rebuilt em is changed to 5500.
