ABSTRACT
Most connections to an Oracle server are network connections which use Transmission Control Protocol/Internet Protocol (TCP/IP) and Ethernet as the underlying protocols. Th ese connections are made up of network packets-TCP/IP packets packaged within Ethernet frames. Th e packets that run over the network can be categorized into three main groups:
1. Packets that form the initiation of the session and include the logon packets. 2. Packets that form the requests from the client to the server-including the Structured Query
Language (SQL) statements/queries. 3. Packets that form the responses from the server to the client-including the result sets/
replies to the queries.
