Departmental Topology
1-8 Advanced Topologies for Enterprise Deployments
Description
This topology (Figure 1–4) consists of an OracleAS Infrastructure, plus several middle
tiers, including at least one Portal and Wireless middle tier. This topology uses two
metadata repositories:
one for product metadata (installed on computer 2). The Portal and Wireless
middle tier uses this metadata repository.
one for Identity Management services (installed on computer 1). All the middle
tiers use this metadata repository for Identity Management services.
Expanding the Topology
You can install Oracle Application Server middle tiers on additional computers, as
needed. You would associate these middle tiers with either metadata repository. For
more information, see Oracle Application Server 10g Administrators Guide.

in High Availability Environments" in the Oracle Application Server 10g Installation
Guide for specific steps.
This topology makes the following assumption:
When you install the OracleAS Infrastructure 10g, you create a new Oracle
Internet Directory.
