EDG: Clarification on the relationship between Oracle Traffic Director (OTD), Virtual Server and Origin Server Pools (Doc ID 2212219.1)

Last updated on AUGUST 07, 2018

Applies to:

Oracle SOA Suite - Version 12.2.1.0.0 and later
Oracle Traffic Director - Version 12.2.1.0.0 and later
Information in this document applies to any platform.

Goal

When following Chapter 12 of the Fusion Middleware Enterprise Deployment Guide for Oracle SOA Suite (E73511-01) to install and configure Oracle Traffic Director 12c (12.2.1) with Oracle SOA Suite, the following environment configuration is being used:

1. An F5 hardware load balancer configured with a virtual host name address.
2. Two VMs are configured for the Web Tier.  These VMs are front-ended by the F5 load balancer. The virtual host name address on the load balancer is forwarding requests to these VMs.
3. Oracle Traffic Director (OTD) is installed on each of these VMs in standalone mode.
4. There are two Oracle VMs in the FMW tier hosting WebLogic Server 12c.

As mentioned in section "12.10.4 Summary of the Origin Servers and Virtual Hosts", the following Origin Server pools were created (based on the products installed):
admin-pool
wsm-pool
soa-pool
ess-pool
osb-pool

A question arises:

Per table "Virtual Servers Required for Each Product" on page 12-20 of the document, Virtual Server, soainternal.example.com, is tied to the following Origin Server pools:
soa-pool
wsm-pool
ess-pool

However, when creating a Virtual Server, it seems that only one Origin Server Pool can be associated with a Virtual Server.

Is it necessary to associate multiple Origin Server pools with one Virtual Sever?
