Net8 is the fundamental Oracle technology that allows Oracle services and clients to communicate with each other over a network. Net8 is most often used to connect client software to Oracle database servers. It may also be used to connect database servers to one another, allowing communication between distributed databases.This practical guide provides the information that readers, especially database administrators, need to know in order to install configure, tune, and troubleshoot Net8. It discusses how Oracle's network architecture, products, and name resolution methods work, and it provides the details of client and server configuration using a variety of Oracle protocols and networking products, including:

The Oracle Internet Directory (OID), Oracle's implementation of the standard Lightweight Directory Access Protocol (LDAP). This directory can be used to maintain a central repository of net service names that can be referenced by all clients.Oracle Names, a networking component used mainly in earlier versions of Oracle, that allows net service names to be defined centrally.Multi-Threaded Server (MTS), an environment in which the client connections share access to a pool of shared server processes.Oracle Connection Manager, a Net8 component that acts much like a router and provides protocol conversion, connection concentration, and access control.The book also describes the utilities Oracle provides to help manage a Net8 environment; these include the Listener Control Utility (lsnrctl), the Oracle Names Control Utility (namesctl), the Oracle Connection Manager Control Utility (cmctl), tnsping, and Net8 Assistant. In addition, it provides a variety of networking troubleshooting techniques and commonly encountered Net8 configuration problems, and provides complete syntax for all networking files and commands.
