Oracle Database Discussions

I've installed Oracle 11g Enterprise Edition (basic installation with starter database) on my laptop. I've created two databases and the link to
access Database Control (Enterprise Manager) for each is as follows

[https://192.168.2.3:5500/em]
[https://192.168.2.2:1158/em]

I cannot access either of them. I've tried [https://localhostname:####/em,] still no access.

The system variable(s) ORACLE_HOME is not currently defined. I've tried to define it as follows, ORACLE_HOME=C:\app\product\11.1.0\db_1.

In Windows XP services OracleDBConsoleMyDB1 and OracleDBConsoleMyDB2 each service is
set to Automatic . . . but neither shows current status.

The databases are up and running, I can connect and query from each.

How can I get the web interface to Enterprise Manager to work?

Thanks.
