Using Parallel Queries

In general, parallel queries are optimal for Decision Support System (DSS) and Online Analysis Processing (OLAP). They are also optimal for analytical systems that have large data collections, multiple CPUs with a low number of concurrent users, or Oracle Real Application Clusters (Oracle RAC) nodes.

Oracle Text supports the following parallel queries:

• Parallel Queries on a Local Context Index

• Parallelizing Queries Across Oracle RAC Nodes
