It Starts to Clear Up

After some dabbling and a few internet searches i understood a few things:

1. Oracle's lovable "2 Day DBA" tells that when the DBA uses DBCA to delete a database "on Windows, any associated services are also deleted". So services are added for every database created; "ORCL" is the default name of the database created automatically; therefore OracleDBConsoleorcl is really OracleDBConsole + orcl. It's unfortunate that they didn't even insert an underscore there. They also change ORCL to orcl freely, which is annoying (e.g., there is a service called OracleJobSchedulerORCL).
2. When, just out of curiosity i googled up OracleDBConsole, i came upon Mark Rittman's lovely website, where i finally understood that the Enterprise Manager is a separate product and it's Grid Control is another separate product. So i went to Oracle's download site and indeed, there was the Enterprise Manager Grid Control, but that download was bigger than the database itself -- over 1GB. This is rather insane, so i passed.
3. The web-based Enterprise Manager is accessible through pointing the web browser to http://localhost:5500 (or http://sugarcube:5500). It is only available when the notorious OracleDBConsole service is running. It also seems to be terribly slow. But maybe i have to configure something. Or, for that matter, read chapter 3 of "2 Day DBA".
