2-6 Advanced Topologies for Enterprise Deployments
2.4 Enterprise Topology: Development Life Cycle Topology Installation
and Configuration
Table 2–4 describes the installation and management considerations for the
development life cycle topology:
2.5 Enterprise Topology Post-Installation Tasks
This section describes post-installation tasks you’ll need to perform for these areas of
your enterprise deployment topology:
■ Infrastructure
■ OracleAS Portal and Oracle Application Server Wireless
■ Oracle Application Server Single Sign-On
Third-Party Products Depending on the load on the application, Load balancers
might be needed
Table 2–4 Considerations for the Development Life Cycle Enterprise Topology
Consideration User Considerations
Install Test Environment: Single host for mid tier and Infrastructure
(all services from one DB).
Staging Environment: Multiple mid tiers on one single big
machine or multiple machines with either dedicated or shared
product metadata services, but always shared security services.
Production Environment: Very similar to Staging environment,
except now using enterprise wide security service
Oracle Application Server won’t break when there are hard
disk replacements, CPU changes, or RAM upgrades
Management Test - Stand Alone or command line tools
Development - Stand Alone or centralized management
Production - Centralized Management
Security Fluid Security requirements
Re-association of security services is mandatory
Application Deployment
and Performance
Shutdown/startup, deploy time are prioritiesFrequent
reconfiguration of tunable parameters, needs to be fastMay
have multiple versions installed and possibly runningThis is
the environment for testing load balancing, combinations of
applications on one box.
High Availability (HA) Testing Environment: Not a concern. Applications and specific
configuration files will be backed up.
Staging Environment: Cold Failover Cluster or Local DG.
Complete cold backup.
Production Environment: RAC or Cold Failover Cluster and
Remote DG for Disaster Recovery. Complete cold backup.
Third-Party Products Depending on the load on the application, DMZ, firewalls,
load balancers, routers might be needed.
