| Shared Server is a scalability option of Oracle. It provides a way to increase the number of supported user processes while reducing the overall memory usage. This configuration is well suited to high-volume, small-transaction-oriented systems with many users connected. Because users share processes, the number of overall idle processes is also reduced. It is not well suited for large data retrieval type applications such as decision support. |
