Oracle White Paper—Oracle Portal Enterprise Deployment Guide: 11.1.1.2

• Components are separated between DMZs on the Web Tier, application tier, and the

directory tier.

• Direct communication between two firewalls at any one time is prohibited.

• If a communication begins in one firewall zone, it must end in the next firewall zone.

• Oracle Internet Directory is isolated in the directory tier DMZ.

• Identity Management components are in the DMZ.

• All communication between components across DMZs is restricted by port and

protocol, according to firewall rules.

High Availability

The Enterprise Deployment architectures are highly available, because each component or

functional group of software components is replicated on a different computer, and configured

for component-level high availability.
