Here's the extremely helpful answer given by AWS Tech Support.
No there is no way of connecting to an Existing Oracle DB without a BYOL license type. The BYOL means that you already own a valid Oracle license and would just like to use it. If you use the On-Demand, it means Amazon provides you a valid license included in the price, so having said this you would have to create a new Oracle DB instance which is what you are seeing in Elastic beanstalk.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
