http port change in ERP from 80 to 1001

[satish]

Dear erman,

Our EBS environment is in intranet.we have a requirement to change the load balancer port from 80 to any other port

2 node application server     R12.2.5

2 node db server (rac+Asm)   version 12.1.0.2

load balancer login url http://erpuat.lod.com

Due to security concerns,we would like to change the load balancer port from 80 to some other port.We dont want https,so we dont use port 443.

We have changed the load balancer port from 80 to 1001 and tested the url and it is working,but our concern is
*can we use port 1001 for http in lb and in our ebs?

Thank you

Are you asking the Load balancer side or EBS side?
Because load balancer port is just a configuration on EBS side, it is just something that EBS knows. That is EBS behaves according to that port.. That port's availability is not related with EBS apps server , it is in load balancer.
In EBS side, the ports that need to be available is Oracle Http Server's listen port, Weblogic ports and etc.

The flow is generally like below->

LB :> OHS ....

or if I give more detail with ports;

LB:80 -> OHS:8000 ....

Please clarify your question and come again.

Thanks for the update erman.

1)Load balancer port is 80..Now we want to change it to some other port.
Just want to confirm if we can use any port between 80 and 1024

2)After changing port,new url will be <a href="http://erpuat.lod.com:newport....old">http://erpuat.lod.com:newport....old url is http://erpuat.lod.com
If client dont want to enter port in url,can we setup any redirection rule in EBS servers?
or do we need to perform the redirection in load balancer?

Thanks,

Anything that you do in Load Balancer level is load balancer's concern.
We only make some changes(for load balancer configuration) in autoconfig xml of apps tier and run autuconfig to manage that change.
So if you change the port of load balancer url, then we need to make our EBS to be configured accordingly.
I guess you know all of that.

As for the redirection question, yes load balancer team & network team should manage that change.
What needs to be done here is, redirecting the port 80 of that load balancer entry point to the port 1024.
Clients who don't want to enter any port number to their browser bar, can be managed that way.
I guess it is called as iRule in F5/big IP (load Balancer) world.
anyways, your Load Balancer admins should guide you on this.

so the flow can be;

client -> port 80 of load balancer -> port 1024 of load balancer -> listen port of EBS HTTP Server .

However; the question is -> why do you change that load balancer url's port then? :)

Thanks for the update.Network team is going to block port 80 due to security guidelines and so we have to change it to some other port.
