Oracle Parallel Processing Explained

In Oracle database, parallel processing refers to splitting a query or operation into multiple parts and executing these parts simultaneously on multiple processors or servers to speed up the execution speed of the query or operation. By using parallel processing, the database can leverage multiple processors, servers, or cores to process large amounts of data simultaneously, thereby improving the performance and throughput of the database. Parallel processing in Oracle database is typically used in large data warehouses or analytical applications to significantly speed up the execution speed of complex queries. Oracle database provides a range of parallel processing features, including parallel queries, parallel DML (Data Manipulation Language), and parallel DDL (Data Definition Language). By configuring and optimizing these parallel processing features, the performance and processing capability of the database can be maximized.
