This appendix provides example worksheets that characterize host requirements for typical deployment scenarios.
Guidelines
Components Required for all Deployments
You must install the following components:
Administrative Portal
Portal
Image Service
Plumtree Search
Automation Service
ALUI Database
Optionally, install the following additional components to add specific functionality:
ALI API Service
Required for access to the ALI SOAP API.
Document Repository Service
Required to support document upload, Publisher, and Collaboration.
Publisher Publisher Database
Required to provide template-based branding for portal communities and the full set of Publisher features and portlets.
Collaboration Collaboration Database
Required for Collaboration features and portlets.
Studio, Studio Database
Required for Studio features and portlets.
Analytics Analytics Database
Required for Analytics features and portlets.
General Principles
All machines should have multiple CPUs.
More RAM generates better performance for all products.
Disk speed is more important for the Database Server, Document Repository Service, and Search.
One-Host Portals
Usage
Demonstration, proof of concept, development, or test environment.

Risks and Mitigation
A two-machine configuration might be suitable for user acceptance testing for 100-200 users, where system availability is not a priority. If you plan to deploy a two-host portal for a small number of users, consider the following risks and mitigating factors.
Risks
Suggestions
The Automation Service might draw CPU and memory from the Portal component during crawls, maintenance operations, and user synchronization.
Schedule the Automation Service to run its jobs at night.
Collaboration, Publisher, Studio, Search, Analytics, and the database compete for memory, slowing performance.
Do not index a large number of documents, host many Studio databases, or publish a lot of content.
Increase the amount of RAM on the second machine.
Set all components to use a smaller memory footprint.
If performance is still unacceptable, move the database to a separate server and follow the three-machine configuration option.
Three-Host Portals
Usage
Minimum host requirements for a production portal.
If you plan to deploy Publisher, Collaboration, Studio, or Analytics, BEA recommends a three-host portal only for demonstration, proof of concept, development, or testing environment.

Caution:
If you deploy on Oracle databases, install the database servers on a host separate from all other portal components. For a three-host deployment, follow the template for a two-host deployment and install only the database servers on the third host.
