Oracle Fusion Middleware Release Notes for Oracle Directory Server Enterprise Edition

Join Data View Searches

To optimize the performance of searches of a join data view, Directory Proxy Server makes use of Virtual List View (vlv) indexes. It helps you to avoid the scenario where search hits the size limits due to the lots of entries from one data source and very few from the others. To use VLV indexes, see Browsing Index in Oracle Fusion Middleware Reference for Oracle Directory Server Enterprise Edition.
