Http://localhost:1158/em cannot open 2

After "Http://localhost:1158/em can't open 1" of some toss, EM still can't access.

So a different way

Oracle 10g replacement of host name or IP causes EM (dbconsole) to start failure solution:

PS: Replaced the host name or IP, if only a simple pl/sql connection database, you can not reconfigure EM,
You only need to change the two files in the Listener.ora and Tnsnames.ora under/oracle/product/10.2.0/db_1/network/admin,
The file: host=**** changed to the corresponding primary key name or IP can be.
If you need to start EM, the above changes will not meet our requirements, and need to reconfigure the relevant information.
->set oracle_sid=ora10g
->emca-repos recreate
...........
Enter the following information:
Database sid:ora10g
Listener Port number: 1521
SYS User's password:
Sysman User's password:
Do you want to continue? [Yes (Y)/no (N)]: Yes
...........
->emca-config Dbcontrol DB
Enter the following information:
Database sid:ora10g
Database control has been configured for DB ora10g
You have chosen to configure database control to manage databases ora10g
This action will remove the existing configuration and default settings and perform the configuration again
Do you want to continue? [Yes (Y)/no (N)]: Yes
Listener Port number: 1521
SYS User's password:
DBSNMP User's password:
Sysman User's password:
Email address of the notification (optional):
Notification of the outgoing (SMTP) server (optional):
-----------------------------------------------------------------
The following settings are specified
The database Oracle_home ... ... d:/oracle/product/10.2.0/db_1.....
Database host name .......... MICROSOF-029
Listen to the program port number ....... 1521
Database SID ... ora10g. ........
e-mail address of the notification ... .....
Notification of the outgoing (SMTP) server ........
-----------------------------------------------------------------
Do you want to continue? [Yes (Y)/no (N)]: Yes
->emctl Start Dbconsole

If you see the word that the service has started successfully, it means that the reconfiguration was successful.
