WebA buffer is a container for data. A logical I/O, also known as a buffer I/O, refers to reads and writes of buffers in the buffer cache. When a requested buffer is not found in memory, the database performs a physical I/O to copy the buffer from either the flash cache or disk into memory, and then a logical I/O to read the cached buffer. Webstatistics are captured along with the high-resource-usage SQL statements. Parameters can be used to set the limits for the SQL statement collection, which will be highly system dependent. It is also possible to capture statistics from an individual session as part of a snapshot by using the i_session_id parameter to the procedure. gfl2c40030sn
