Web Reference: Oracle Database bypasses the buffer cache for particular operations, such as sorting and parallel reads. To use the database buffer cache effectively, tune SQL statements for the application to avoid unnecessary resource consumption. Oracle has the ability to write data into a data file without first writing them into the buffer cache. In such an operation, the data is appended behind the high water mark (HWM) of a table. The buffer cache is a critical component of Oracle's memory architecture, designed to store copies of data blocks that have been read from data files. This tutorial covers how to use and optimize the buffer cache to enhance the performance of your Oracle database.
