You have to create a whole new database (usually on another box entirely, but it can be on the same as your 'regular' instance). You then have to tell Oracle to create an OMS repository within that new database. Only then can you start the OMS service itself.

You can do all of that in one hit by running the Enterprise Manager Configuration Assistant (emca from the command prompt, or under the Configuration and Migration tools menu option). If you ask it to, EMCA will invoke DBCA (the database configuration assistant) to create the new database for you (and it usually gets called OEMREP). Otherwise, use the same tool to point the EMCA to create a repository within a database you yourself have created (but don't stick the repository inside the database that you actually want to manage via EM).

I prefer to create my own database, rather than let EMCA do the job for me, because EMCA creates an absolutely *huge* database, with all the Java and XML and Intermedia stuff installed that is totally unnecessary for the job. It only needs to be quite small, and certainly doesn't need all those extras.

I realise you are on Windows, but you may find the last 30 pages or so of my paper on installing onto Red Hat 9 useful. It goes through exactly the steps needed to get Enterprise Manager console working, and applies, broadly, to any platform. Check the website white papers.
