The listener process(es) on a server detect incoming requests from clients for connection - by default on port 1521 [5] - and manage network-traffic once clients have connected to an Oracle database. The listener uses a configuration-file - listener.ora - to help keep track of names, protocols, services and hosts.
The port numbers in the range from 0 to 1023 (0 to 2 10 − 1) are the well-known ports or system ports. [3] They are used by system processes that provide widely used types of network services. On Unix-like operating systems, a process must execute with superuser privileges to be able to bind a network socket to an IP address using one of the ...
After data transfer is completed, the connection termination closes the connection and releases all allocated resources. A TCP connection is managed by an operating system through a resource that represents the local end-point for communications, the Internet socket .
Oracle Communications Messaging Server is Oracle's messaging server software. The software was obtained by Oracle as part of the company's acquisition of Sun in 2010. Oracle's Messaging Server could potentially be the most widely deployed commercial email server on the planet, with claims of 150 million mailboxes deployed worldwide (mostly by ...
Many non-IP-based networks, such as X.25, Frame Relay and ATM, implement the connection-oriented communication at the network or data link layer rather than the transport layer. In X.25, in telephone network modems and in wireless communication systems, reliable node-to-node communication is implemented at lower protocol layers.
The OPC specification was based on the OLE, COM, and DCOM technologies developed by Microsoft Corporation for the Microsoft Windows operating system family. The specification defined a standard set of objects , interfaces e.g. IDL and methods for use in process control and manufacturing automation applications to facilitate interoperability .
[citation needed] In 1984 Donald Gillies at MIT wrote a ntcp multi-connection TCP which runs atop the IP/PacketDriver layer maintained by John Romkey at MIT in 1983–84. Romkey leveraged this TCP in 1986 when FTP Software was founded. [39] [40] Starting in 1985, Phil Karn created a multi-connection TCP application for ham radio systems (KA9Q ...
The Oracle iPlanet Web Proxy Server, is a popular HTTP/1.1 Proxy server software developed by Sun Microsystems. OiWPS 4.0 is widely used for proxying, caching, and filtering web content, boosting network security and performance, as well as to protect and secure, and load balance across, content servers.
