J2EE Applications Topology
2-2 Advanced Topologies for Enterprise Deployments
2.1.1 Hardware Requirements
You can look at Table 2–2 to get an idea of some of the hardware requirements you’ll
need to meet to successfully install, configure, and run various components of an
enterprise deployment topology.
2.1.2 Installation Sequence
Install the items in the following order:
1. Infrastructure DMZ: Install an OracleAS Infrastructure 10g with Identity
Management services and Oracle Application Server Metadata Repository. See
Chapter 5, Section 5.14, "Installing OracleAS Infrastructure" in Oracle Application
Server 10g Installation Guide for complete installation information.
Management Central Management Services
Oracle Application Server plugs into existing central
management services
Role-based management (initial functionality in 904 and major
functionality in Oracle Application Server)
Multiple administrators
Backup and Recovery: Complete cold backup of the entire
distributed environment
Security Global OID/SSO or logical SSO (consisting of 1 or more SSO
instances) sharing the same logical OID (consisting of 1 or
more OID instances)
Both SSO and OID behind the external firewall for internal
users
When hosting applications for both internal and external users
(such as MOC), security considerations will need to make sure
some security services can be shared by both users.
Integrating with departmental third-party directories (iPlanet,
Active Directory, eDirectory)
Provisioning/De-Provisioning users
Application Deployment
and Performance
J2EE applications deployed on Oracle Application Server
Clusters with or without Web Cache
Portal application using Web Cache, even on a single node
environment
Forms applications working against a OLTP System with no
SSO
BI applications working against a data warehouse with tighter
security
All applications accessible by Portal and Wireless devices
Self Service Applications (using IP and Workflow)
High Availability (HA) Infrastructure HA: Multiple types of HA solutions for different
Infrastructure Services
Optional: OPMN based cluster management for middle tier
applications
Third-Party Products Firewall, load balancers, hardware clusters, hardware
accelerators
