The DBA Toolkit and Security
The OEM contains a set of database administration tools you can use to perform the normal, day-to-day tasks required of a DBA.

If you are a seasoned DBA, you will still find many tools within the product set to help you be a better DBA. We recommend that, if you are a new DBA, you take advantage of the “Show SQL” option available from most of the tool screens to help you learn the SQL commands used to execute the various tasks you will perform with the OEM.
