To create a new Oracle 11.2.0.4 database instance when using the "Launch DB Instance Wizard" in the AWS Management Console, select the DB Engine Version "11.2.0.4v1".
To upgrade an existing database instance, use the "Modify" option in the AWS Management Console and select the DB Engine Version "11.2.0.4v1". Before you upgrade a production database instance, we recommend that you test the upgrade process with a test DB instance to verify how long the upgrade process takes, and that you test your application with the new DB Engine version. We do not recommend upgrading Micro DB Instances, because the upgrade process may run slowly and impact database performance.
