Updating inside an oracle
Security Groups By default, DB instances are created with a firewall that prevents access to them.
You therefore must create a security group with the correct IP addresses and network configuration to access the DB instance.
In order to deliver a managed service experience, Amazon RDS does not provide shell access to DB instances, and it restricts access to certain system procedures and tables that require advanced privileges.
The Bring Your Own License model is supported on Amazon RDS for the following Oracle database editions: Amazon RDS supports Multi-AZ deployments for Oracle as a high-availability, failover solution. For more information, see High Availability (Multi-AZ).Use this account for any administrative tasks such as creating additional user accounts in the database.The SYS user, SYSTEM user, and other administrative accounts are locked and cannot be used.Amazon RDS does not allow direct host access to a DB instance via Telnet or Secure Shell (SSH).When you create a DB instance, the master account that you use to create the instance gets DBA user privileges (with some limitations).
