This section describes data views that route requests targeted at a list of subtrees to a set of data-equivalent data sources.
The example in this section has multiple data sources that each contain the same set of subtrees. The data sources are data-equivalent and pooled into one data source pool for load balancing. A data view is configured for each subtree to expose that subtree to client requests. Figure 17–3 shows the example deployment.
A request is exposed to a data view only if the target DN is subordinate to the base DN of the data view. When a request is exposed to a data view, the request is forwarded to the data source pool specified by the data view.
If the target DN of a request is not subordinate to the base DN of any data view, Directory Proxy Server returns an error.
In Figure 17–4, requests that target dc=example1,dc=com or dc=example2,dc=com are forwarded to the data source pool. Directory Proxy Server returns an error for requests that target neither dc=example1,dc=com nor dc=example2,dc=com.
For information about how to configure the data views in this section, see Data Views That Route Requests When a List of Subtrees Is Stored on Multiple, Data-Equivalent Data Sources in Sun Java System Directory Server Enterprise Edition 6.1 Administration Guide.
