Before sending data across the network, Oracle Net buffers and encapsulates data into the session data unit (SDU). Oracle Net sends the data stored in this buffer when the buffer is full, flushed, or when database server tries to read data. When large amounts of data are being transmitted or when the message size is consistent, adjusting the size of the SDU buffers can improve performance, network utilization, or memory consumption. You can deploy SDU at the client, the application Web server, and the database server | ORACLE Oracle Database SQL Reference 10g Release 2 B14200-02 December 2005 Oracle Database SQL Reference 10g Release 2 B14200-02 Copyright 1996 2005 Oracle.
