AWS ALB with Oracle e-business suite

Question

I am facing an issue with the ALB.
We are having the EC2 with Oracle e-business suite installed on it. It is in a private subnet.
The ALB is in a public subnet

When we access the url of the ALB, it shows that the page will be redirected back to the DNS name of the ec2 instance.

ALB URL : alb.something.com:8080
EC2 URL : ec2.internal.com:8080

Is there something to be done on the ALB ? cause I have tried the redirect actions with no success.
or this is something to do with the Oracle configuration ? I am no expert in Oracle. but I am trying to find the issue here ?

Accepted Answer

This is a common occurrence with applications that are not "aware" of network devices such as load balancers.  
  
Somewhere in the application you will need to configure the "application URL" and rather that the hostname update to use the loadbalancer.

I believe this Oracle document should help you.  
https://docs.oracle.com/cd/E18727-01/doc.121/e12893/T174296T174298.htm  
Where it states  put in the ALB name and port.
