1.1 About Enterprise Topologies and Why Oracle Recommends Them

An enterprise topology is an advanced installation and configuration of Oracle

Application Server, usually in a large setting such as a data center.

In an enterprise deployment topology, there are three main application server

deployment goals:

■ Ensuring that quality of service exists in the software and hardware configurations

in any given topology:

■ The enterprise systems efficiently managed and balanced workloads;

■ Applications run efficiently when resources such as hardware, network tools,

etc., are added or removed in a deployment topology;

■ Planned and unplanned activities such as system management tasks have zero

downtime in the topology.

■ Provide a secure application server platform;

■ Security and Identity Management:

■ Ensure that users can be provisioned and managed centrally;

■ Ensure that delegation of administration is possible and done consistently;

■ Provide the ability to integrate with other security and identity management

systems in an enterprise topology.

■ Software Provisioning and Management:

■ Simplify and automate application distribution and accessibility;

■ Ensure that systems can be self managed;

■ Monitor and manage many systems as one logical unit;
