Client/server communicationThese topics explain the concepts and terms that you must understand in order to configure client/server communication.
Local connectionsA local connection is a connection between a client and the database server on the same computer.
Stream-pipe connections (UNIX™ and Linux™)A stream pipe is a UNIX™ interprocess communication (IPC) facility that allows processes on the same computer to communicate with each other.

Stream-pipe connections (UNIX and Linux)

A stream pipe is a UNIX™ interprocess communication (IPC) facility that allows processes on the same computer to communicate with each other.

Stream-pipe connections have the following advantages:

Unlike shared-memory connections, stream pipes do not pose the security risk of being overwritten or read by other programs that explicitly access the same portion of shared memory.
Unlike shared-memory connections, stream-pipe connections allow distributed transactions between database servers that are on the same computer.

Stream-pipe connections have the following disadvantages:

Stream-pipe connections might be slower than shared-memory connections on some computers.
Stream pipes are not available on all platforms.
When you use shared memory or stream pipes for client/server communications, the hostname entry is ignored.
