Options for Oracle DB Instances
This section describes options, or additional features, that are available for Amazon RDS instances running the Oracle DB engine. To enable these options, you add them to an option group, and then associate the option group with your DB instance. For more information, see Working with Option Groups.
Some options require additional memory to run on your DB instance. For example, Oracle Enterprise Manager Database Control uses about 300 MB of RAM.

You can adjust the Oracle parameters so that the database requires less RAM; alternatively, you can scale up to a larger DB instance.
