Sun Java System Portal Server 7.2 Deployment Planning Guide

Building Module Solution Recommendations

This section describes guidelines for deploying your building module solution.

How you construct your building module affects performance.

Consider the following recommendations to deploy your building module properly:

Directory Server

Identify your Directory Server requirements for your building module deployment. For specific information on Directory Server deployment, see the Directory Server Deployment Guide.

Consider the following Directory Server guidelines when you plan your Portal Server deployment:

The scalability of building modules is based on the number of LDAP writes resulting from profile updates and the maximum size of the LDAP database.


Note –

If the analysis at your specific site indicates that the number of LDAP write operations is indeed a constraint, some of the possible solutions include creating building modules that replicate only a specific branch of the directory and a layer in front that directs incoming requests to the appropriate instance of portal.

Search Service

When you deploy the Search Engine as part of your building module solution, consider the following:
