Enterprise Topology Overview 1-9
1.5.1 Installation Sequence
Install the items in the following order. The computers are listed in Figure 1–4.
1. Computer 1: Install an OracleAS Infrastructure 10g with Identity Management
services and
OracleAS Metadata Repository. See Section 6.14, "Installing
OracleAS Infrastructure 10g" in the Oracle Application Server 10g Installation Guide
for specific steps.This creates a database to contain the
OracleAS Metadata
Repository. It also creates an Oracle Internet Directory.
2. Computer 2: Install a second OracleAS Metadata Repository. See Section 6.16,
"Installing OracleAS Metadata Repository in a New Database" in the Oracle
Application Server 10g Installation Guide for specific steps.When the installer
prompts you to register the OracleAS Metadata Repository, enter the connect
information for the Oracle Internet Directory created in step 1.The Portal and
Wireless middle tier will use this second metadata repository for its product
metadata. See Section 6.10, "Can I Use Multiple Metadata Repositories?" in the
Oracle Application Server 10g Installation Guide for specific steps.
3. Computer 3: Install a Portal and Wireless middle tier. See Section 7.10, "Installing
Portal and Wireless or Business Intelligence and Forms" in the Oracle Application
Server 10g Installation Guide for specific steps.When the installer prompts for Oracle
Internet Directory, enter the connect information for the Oracle Internet Directory
created in step 1. This Oracle Internet Directory contains the registration for the
OracleAS Metadata Repository installed in steps 1 and 2.When the installer
prompts for the OracleAS Metadata Repository, select the OracleAS Metadata
Repository installed in step 2.
4. Computer 4: Install a J2EE and Web Cache middle tier. See Section 7.8, "Installing
J2EE and Web Cache with OracleAS Cluster and Identity Management Access" in
the Oracle Application Server 10g Installation Guide for specific steps.When the
installer prompts for Oracle Internet Directory, enter the connect information for
the Oracle Internet Directory created in step 1.When the installer prompts for the
OracleAS Metadata Repository, select the OracleAS Metadata Repository installed
in step 1.
1.6 Development Life Cycle Topology
This topology is a combination of other topologies to support moving applications
from test to stage to production environments:
Test environment: Application developers test their applications in their own
environments. Examples of testing environments can be found in the Oracle Application
Server 10g Installation Guide:
■ Section 10.1, "Java Developer Topology"
■ Section 10.2, "Portal and Wireless Developer Topology"
■ Section 10.3, "Forms, Reports, and Discoverer Developer Topology"
Stage environment: Quality assurance personnel test all applications before deploying
them to the production environment. In this environment, you can use the topology
described in Section 1.5, "Departmental Topology". This topology in a stage
environment runs applications from all departments, not just from a single one.
Production environment: Applications are ready for use by users internal and external
to the enterprise. See Section 1.3, "Enterprise Data Center Topology: J2EE
Applications"
